1 introduction
The emergence of intelligent robots in the 1960s opened up a new era of intelligent production automation. Today, more than 50 years after the advent of industrial robots, robots have been regarded as an indispensable production tool. The technological progress in the fields of sensor, control, drive and materials has opened up a new field of robot application. Intelligent mobile robot is an important branch of robotics.
2 basic system composition and related technologies of intelligent mobile robot
Because intelligent mobile robot has a broad application prospect in dangerous and harsh environment and civil use, countries all over the world pay close attention to its development. The five common system elements are as follows: (1) the mechanical mechanism unit is the skeleton of the intelligent mobile robot, and all the modules of the robot depend on it. The structure and performance of the mechanical mechanism unit, the strength directly affects the stability of the whole robot. With the development of science and technology and the research and development of new materials, the structure and performance of intelligent robot products have been greatly improved, and the technological and dimensional design of mechanical mechanisms have become more reasonable and efficient, lighter and more beautiful, more environmentally friendly and energy-saving. more safe and reliable and so on. (2) Power and drive unit provide power source for intelligent mobile robot. (3) the environment sensing unit is equivalent to the facial features of the intelligent mobile robot. the robot recognizes the surrounding environment and collects various parameters through the sensing unit, and then converts it into a photoelectric signal that can be recognized by the control module. input to the control unit for data processing. (4) the actuator unit is the executive part of the intelligent mobile robot, which can execute commands and complete tasks according to the commands of the control center. Different robots have different actuators, and the design of actuators affects the efficiency, accuracy, stability and reliability of the actions to be performed. (5) as the core part of the whole mechanical system, the information processing and control unit, like the human brain, regulates the whole system and directs all activities by it. Collect and store the information collected from the sensor, analyze all the information, plan and make decisions, and output commands. To enable the robot to run purposefully.
Intelligent mobile robot is an integrated electromechanical system which integrates many functions, such as environment perception, dynamic decision-making and planning, behavior control and execution. It is an important research achievement of many disciplines, such as sensor technology, control technology, mobile technology, information processing, artificial intelligence, electronic engineering, computer engineering and so on. in a sense, it is the product of machine development and evolution. it is one of the most active fields in the development of science and technology at present.
3 a kind of obstacle surmounting robot
The mobile robot we designed (figure 1) has good maneuverability, and the front wheel, front wheel and rear wheel can move up and down independently. The front guide wheel (figure 1) controls the swing angle of the rocker through the rotation angle of the crank disc to drive the movement of the related planar linkage mechanism, so as to realize the extension and contraction of the front guide wheel to realize climbing. The side driving mechanism on both sides of the robot is a planar link-slider over-obstacle mechanism, and the front and rear wheels (figure 1) drive the movement of the planar linkage mechanism through the movement of the guide rod in the slot respectively, realizing the extension and contraction of the front and rear wheels and realizing the obstacle crossing function. The robot can achieve a larger obstacle height through the design of the size, and can also achieve the climbing of various types of obstacles by reasonably controlling the swing angle of the wheel.
4 the application of intelligent mobile robot
With the progress of science and technology, the function of robot is constantly improved, and the application range of intelligent mobile robot is also greatly broadened. It is not only widely used in industry, agriculture, medical treatment, service and other industries, but also well applied in harmful and dangerous situations such as danger discharge, ocean development and space exploration (such as radiation, disaster area, poison, etc.).
4.1 Land Intelligent Mobile Robot
In the late 1960s, in order to complete the occupation of space and the lunar exploration program, the Soviet Union and the United States respectively developed and applied mobile robots to achieve various tasks such as alien soil sample collection and soil analysis. The emergence of land intelligent mobile robot is to help human beings complete the impossible tasks. Land mobile robots are also widely used in the military, which can remove explosives, mine sweep, detection, remove obstacles and so on. In recent years, intelligent mobile robots have gradually begun to integrate into people’s daily life.
4.2 underwater intelligent mobile robot
In recent years, with the increasing demand for resources, people begin to develop atomic energy and marine resources, and the underwater environment is very complex (poor visibility, difficult positioning, fluid changes, etc.). Underwater intelligent mobile robot has attracted attention because of its advantages in seafloor resources exploration. In recent years, scientists at Kiel University in Germany have developed a new deep-water robot, ROV Kiel 6000, which can reach a depth of 6000 meters in search of mysterious deepwater creatures and “white gold” combustible ice.
4.3 Bionic Intelligent Mobile Robot
In recent years, many robot research institutions around the world pay more and more attention to the research work of bionics and mechanism. In some cases, bionic robots have unique advantages, for example, serpentine robots have a low center of gravity and can imitate the movements of snakes, and shuttling through disaster sites and other complex terrain can help humans accomplish a variety of tasks. In addition, there are bionic pet dogs, bionic fish, bionic insects and so on.
5 the development direction and prospect of intelligent mobile robot
The main factors that affect the development of mobile robot are navigation and positioning technology, multi-sensor information fusion technology, multi-robot coordination and control technology and so on.
(1) highly intelligent emotional robot. With the development of science and technology, people have higher and higher requirements for human-computer interaction technology. Emotional mobile robot with human intelligence is the future development trend of mobile robot. At present, mobile robots can only be said to have partial intelligence, and people are eager to have safe and reliable highly intelligent robots that can communicate. Although it is still very difficult to realize a highly intelligent emotional robot, one day, with the breakthrough of science and technology, it will become a reality.
(2) highly adaptive and multi-functional robot. The emergence of robots serves human beings, and there are still many unknown worlds waiting for us to explore in nature. Human beings are unable to set foot in all kinds of dangerous, complex and changeable environments, so people are eager to have robots that can replace human beings. Highly adaptive multi-functional robots will also be one of the development directions of robots.
(3) Universal service robot. With the development of science and technology, robots should be more and more easily integrated into people’s daily life and serve people in daily life. For example, in the family, robots can help people do all kinds of housework and have a close relationship with people’s lives.
(4) Special intelligent mobile robot. According to different application fields and different purposes, the design of a variety of special intelligent mobile robots is the future development direction, such as nanobots, space exploration robots, deep-sea exploration robots, entertainment robots and so on.
6 concluding remarks
In a word, intelligent mobile robot involves sensor technology, control technology, mobile technology, information processing, artificial intelligence, control engineering and other multidisciplinary technologies. In the future, intelligent mobile robot will move towards life, which is safe and reliable and easy to operate. Although intelligent mobile robots are developing at an amazing speed, there is still a long way to go to achieve highly adaptive, intelligent, emotional and multi-functional mobile robots.

The design method of robot is undoubtedly a problem that many people are very interested in, so this paper makes a detailed exploration on the design method of robot.
Keywords robot; design; method
1. Preface
Throughout the history of human development, the progress of tools can drive human civilization. Nowadays, design is developing in the direction of intelligence, and robot is an important product of human beings in the process of developing intelligence. Therefore, the common design method of robot is a necessary tool for designers.
two。 Hardware Design of Control system
Under the background of the continuous development of modern science and technology, the amount of heavy physical labor involved in the industrial field is increasing. It is difficult to realize some of the labor tasks by relying solely on manpower. And in order to well complete the relevant production tasks in the industrial field. Through the research and application of the robot device, the hardware part of the robot control system is mainly composed of five modules: control module, tracking module, obstacle avoidance module, motor drive module and power module.
(1) Control system module. ATmega128 is an 8-bit low-power CMOS microprocessor based on AVR RISC structure, which is fast in operation and has multiple PWM outputs. It can process the input signals generated by the circuits such as speed measurement and obstacle avoidance, and output the control signals to the drive amplifier circuit to control the speed of the motor. The PWM signal generated in this way is better in real-time than the PWM signal generated by timer interruption, and will not occupy the timer resources of the system.
(2) tracking module. Tracking refers to the car walking along the white guide line on the competition field, and the schematic diagram of the tracking module is shown in figure 2. The tracking module adopts grayscale sensor, the transmitting tube is ordinary LED lamp, and the receiving tube is photosensitive transistor 3DU33. The working principle is: different color objects reflect different brightness of LED emitted light, photosensitive transistor 3DU33 receives these different brightness light, it will present different voltage Vx. The Vx is input to the in-phase end of the comparator LM339 and compared with the voltage V0 set by the potentiometer. When VxV0, the comparator outputs a high level. When the Vx tracking robot is composed of seven gray sensors, the front and rear ends of the comparator are tracking modules. Among them, the middle three grayscale sensors play the role of line patrol, the grayscale sensors at both ends play the role of detecting bends, and the remaining two grayscale sensors patrol and detect bends alternately. Experiments show that the layout of such grayscale sensors has a good effect of robot tracking, and the “performance-to-price ratio” is very high.
(3) obstacle avoidance module. The obstacle avoidance module mainly uses the infrared transmitting and receiving sensor. When the infrared induction obstacle avoidance module is close to the object, it outputs the low-level signal; when the object is not sensed, it outputs the high-level signal. If the signal line is connected to the control port of the single-chip microcomputer, the control program can detect obstacles. When the robot is on the path, it can find obstacles and avoid the detour in time.
(4) driver module. The tracking obstacle avoidance robot requires flexible walking and fast response, so the driving motor is required to have the characteristics of “fast speed, timely braking” and so on. The tracking obstacle avoidance robot we designed and manufactured adopts the JMP-BE-3508I drive board module of Zhongming Company, whose input voltage is 11V to 24V and the maximum output current is 20A, which meets the requirements of fast forward, braking and turning. And the speed of the motor reaches 500rpm, and the blocking torque is 8KG.CM, which has a strong braking function. The four PWM output signals of the single chip microcomputer are used to control the rotational speed of the four wheels. The forward, backward and turning of the robot are realized by means of “four-wheel drive” and “differential turning”.
(5) Power supply module. The power module of the tracking robot mainly realizes the following three functions: the stable output voltage of ① is 5V. Therefore, the power supply module we design and manufacture takes 7805 chip as the core, and the input voltage is cut off to 5V. ② provides enough current. The maximum output current of the 7805 chip is 1.5A, while the tracking robot needs a large current, so we use two 7805 chips to power the control system and external equipment respectively. ③ filtering. The 7805 patch capacitor and 10 μ F electrolytic capacitor are connected in parallel at the input and output of the chip to filter high frequency and low frequency signals.
3. Software and hardware module development process and interface program
The main contents are as follows: (1) Image processing module: the camera captures the image in real time, compares the transformed image with the initial image, and finds out the position of the difference in the image through TCP.
(2) TCP communication module: the vision system is connected to the Baikale controller through Ethernet, and the controller can be used as a client or server to transmit data in real time. The defined structure is used for the vision system to transmit position and posture to the robot and the robot to feedback the pose and signal state data to the vision system in real time.
(3) position conversion module: the position and posture of the vision system is converted into that of the robot and transmitted to the robot to control the operation of the robot.
(4) trajectory planning module: carry out trajectory planning and speed planning, and select the optimal trajectory (straight line, arc, irregular curve, etc.) according to the current position and target position of the robot. then the trajectory and speed are interpolated, and the interpolation value is called the robot kinematics algorithm to calculate the reliability of the trajectory, and then the position and speed of real-time interpolation are transmitted to the motion control module.
(5) Motion control module: according to the value of real-time interpolation, combined with acceleration, plus acceleration and other control parameters to the driver.
(6) Servo module: according to the data sent by the controller, combined with the servo control parameters, the drive motor runs to each position with the fastest response and speed.
4. Robot accuracy Calibration and Vision Software processing
4.1 accuracy calibration
Accuracy calibration includes robot accuracy calibration and robot position calibration relative to the vision camera. Before the robot moves, it is necessary to use the laser tracker to calibrate the mechanical parameters such as the length of each axis, zero, deceleration ratio, coupling ratio and so on, and give it to the kinematics and controller system so that the robot can run accurately according to the theoretical trajectory. Go to the specified point. The three-point method and six-point method are used to calibrate the X, Y and Z distance of the robot relative to the vision camera to the position conversion module, and the transformation relationship between the robot coordinate system and the camera coordinate system is determined.
4.2 Visual processing software
It includes fixed vision system calibration module and mobile vision system calibration module. Installing the vision system in a fixed position is equivalent to establishing a user coordinate system for the robot. This module is used for the pose conversion between the computing robot and the fixed vision system. The installation of the vision system on the flange position at the end of the robot is equivalent to establishing a tool coordinate system for the robot to change the position in real time with the motion of the robot. this module is used for the position conversion relationship between the computing robot and the dynamic vision system. Real-time processing of the running communication status and error status of the transmission robot, vision system and Ethernet.
4.3 Design and implementation of man-machine interface
When the robot fails and cannot move the position automatically, such as when it encounters a hardware limit or a collision, you can go to the manual page, select the robot operation, and move the robot to the specified position. For the new palletizing process line, it is necessary to configure system parameters, location information, and product parameters. Palletizing data editing and creation function, the product covers bags, boxes, and variable number of fetching functions. You can add product quantity, change product direction, single-step quantity modification, product position movement, rotation and other settings. On this page, the example generates five packages of bagged products on each layer, numbered from 1 to 5. You can change the actual palletizing order of the products by adjusting the numbering order.
5. Concluding remarks
In short, in the process of robot design, targeted design should be carried out according to the purpose of the design, and the above thinking methods should be used to solve the problems in the design process in time, with the promotion of machine intelligence, there is no doubt that the design of the robot will have a broader sky in the future.

[key words] Fault treatment for the working principle of igm welding robot
0 preface
Robot technology is a high and new technology formed by the integration of computer, control theory, mechanism, information and sensing technology, artificial intelligence and other disciplines. The intervention of this new technology puts forward higher requirements for maintenance technicians. How to ensure the reliability and stability of the welding robot and give full play to the maximum advantages of the robot, the fault repair and equipment maintenance of the robot is particularly important.
Composition and working principle of 1 igm welding robot
1.1 composition of igm welding robot
Igm welding robot is an industrial robot engaged in welding (including cutting and spraying). It has the advantages of fine processing, dexterous movement, high welding precision and good weld shape. It has been widely used in the machinery industry.
1.2 working principle of igm welding robot
Igm welding robot internal axis control principle: through the digital servo board DSE-IBS to process the current position calibration, position drive, speed drive and other information, the processed information is fed to the servo driver, modulated by the pulse width modulator inside the servo driver, and then enlarge the output to promote the servo motor. While the servo motor is moving, the encoder runs synchronously, and the collected position angle information is fed back to the RDW control board. Through the incremental calculation of the RDW board and the position information after data setting, the position information is returned to the DSE-IBS board, and the next cycle is calculated and processed. This process is carried out repeatedly to realize the real-time position change process.
Fault diagnosis and Analysis of 2 igm Welding Robot
2.1 failure types of welding robot
The fault type of welding robot can be divided into software fault and hardware fault, the fault caused by machine software, such as the phenomenon of system shutdown, and the fault caused by machine hardware, such as the fault of drive unit and electrical components. According to the fault phenomenon, it can be divided into three categories: man-made fault, natural fault and sudden fault. For maintenance, it is difficult to remove natural and sudden faults, because this kind of maintenance not only aims at the fault unit itself, but also improves the system, which requires careful analysis, optimization and improvement of fault diagnosis. avoid repeating the eliminated faults and make the system more stable and reliable.
2.2 Common failure treatment of igm welding robot
2.2.1 after the robot is started, the instructor has no alarm message, but the manipulator can not start the arc normally. First of all, check the system whether the wire feed air, found that the wire feeding system can not manually feed wire, the protection cylinder has pressure, but there is no protective gas at the nozzle of the welding torch. Check the welding cable, arc plate and wire feeding plate of the manipulator again, and no fault is found. This shows that the function of the manipulator is normal, and the welding circuit may not be smooth. Whether the welding circuit is normal or not can be judged by measuring the impedance of the welding circuit.
Test procedure for circuit impedance:
I connect the ground wire connecting the workpiece to ensure that the contact part between the ground wire clip and the workpiece is clean and good
Ii turns on the power supply of the robot cabinet and sets the power switch of the Funis welder to the “I” position.
Iii selects the “r” function in the welder secondary menu.
Iv removes the welding torch nozzle, screws the conductive nozzle, and sticks the conductive nozzle to the workpiece surface. It should be noted that in the process of measurement, the contact between the conductive nozzle and the workpiece should be kept clean. The wire feeder and cooling system do not start while the measurement is being carried out.
V gently press the torch switch or tap the wire feed key. The calculation of the impedance of the welding circuit is completed. During the measurement, the right display screen displays “run”
After the calculation of the vi welding circuit, the display screen displays the measured value. The measured impedance of the welding loop is 18 Ω (the normal value is 20 Ω), indicating that the welding loop of the welding robot is unobstructed. After power-off and power-on debugging, the welding robot can start the arc normally, which should be connected to the abnormal contact of the circuit by connecting the grounding clip, disassembling the nozzle, conductive nozzle and so on.
2.2.2 during the welding process of the igm robot, it is difficult to start the arc, the welding current is extremely unstable, and the arc is often broken, and the “Arc fault” arc fault occurs repeatedly.
I check the grounding cable, the measured loop resistance is 9.7 Ω, normal
The best value is 20 Ω.
Ii checks that the wire diameter (diameter 1.2) matches the nominal diameter of the wire feeder.
The iii wire material (G2Si) matches the welding method and welding base metal.
Observation of welding torch nozzle after iv, there are a lot of dust cutting powder, manual delivery of welding wire is not smooth, there is a small amount of bending and wire injury, indicating that wire feeding is not smooth.
V to test the resistance of wire feeding. The wire feeding locking rod and compression rod are opened, and the hand plate retracts the welding wire, and the resistance is found to be very high. It is mostly caused by the blockage of the wire feeding hose or the excessive angle between the hose and the manipulator.
Vi inspection of wire feeding wheel wear, V-shaped wire feeding groove is not easy to be too deep and too wide, it is better to place a welding wire of 1.2 specification, the gap is too large, it will affect the stability of wire feeding and the stability of welding current. When the wire feeding wheel is removed, it is found that the wire feeding wheel is worn seriously, the roundness error is large and the wire feeding groove is too deep. Once the wire feeding mechanism is out of control, it will feed the wire at high speed, and the welding power source can not get normal signal feedback (photoelectric speed measurement is used to measure the wire feeding speed), which can not provide stable current and voltage, resulting in abnormal welding. Replace the wire feeding wheel, wire feeding hose, and adjust the pressure, the fault is removed, and the welding is normal.
2.2.3 the zeroing parameters of igm robot are lost automatically. When the igm robot starts up next time, the zeroing parameters will be lost automatically, the zeros will be recalibrated, the input parameters will be re-calibrated, and the saved parameters will be lost repeatedly. Check the teaching cable, interface, program, shaft card, RDW board lights are all normal, check the backup battery (buffer battery, which is used to provide short-term power supply for the system and store information in the case of power off or accidental power loss) measure the voltage value, one is 8.9V, the other is 12V, the total voltage is 21V, the normal value is 24V, everything is normal after changing a set of batteries, and there is no data loss.
2.3 Analysis and treatment of sudden failures
The fault was unpredictable and it happened suddenly. It appears the most in the actual work. Most of the system faults are affected by the environment, such as the circuit board failure of the control part of the welding robot, the power supply fault, the communication fault and so on, which are reflected in the sudden alarm and unable to eliminate the alarm when the robot is working. Restart and return to normal, but soon there is an alarm, this kind of failure makes the whole system unstable.
In order to further judge whether the drive is good or bad, narrow the fault range
To check the encoder, the encoder used in each axis of the RCI series robot is an absolute encoder, which is an electromagnetic component that can transmit the information of rotation angle, which is composed of two fixed windings (sin winding and cos winding) and a reference winding. The principle is basically similar to that of a rotary transformer. Unplug the X12 plug and measure the resistance values of 11-12, 13-5 and 14-4 terminals respectively, and none of them has a resistance value, indicating that the encoder is abnormal.
Find the 12-axis servo motor, check and find that the encoder plug is locked and the cap has been withdrawn, and the plug connection is loose. The plug is re-inserted and locked in place, and the resistance values of 11-12, 13-5, 14-4 and 9-10 terminals are 94 Ω, 65 Ω, 65 Ω and 600 Ω, respectively, indicating that the windings are normal. After power on, the driver can be turned on normally and the fault is relieved.
3 concluding remarks
Maintenance work is a repeated process in which theory guides practice, and practice promotes theory. The organic combination of theory and practice will make maintenance personnel more in-depth and more accurate in judging and dealing with various faults. Maintenance personnel must have the ability to think, analyze and judge independently, pay attention to observation in operation, do not blindly change the setting and jumper status of welding robots, and form the good habit of making work records. summarize all kinds of fault phenomena and treatment process, accumulate fault diagnosis and maintenance experience, in order to improve the maintenance level.

Digital home is the basic unit of intelligent community system in the future. The so-called “digital home” is based on the family to provide intelligent services covering the whole family, including data communication, home entertainment and information appliance control functions. One of the main contents of digital home design is the realization of communication function, including the communication between the family and the outside world and the communication between the related facilities within the family. From the current development, external communication is mainly through broadband access. Intenet, and the communication within the home, the author uses the relatively competitive Bluetooth (bluetootlh) wireless access technology. Traditional digital families use pc for overall control, which is lack of humanization. According to the idea of artificial emotion, the author designs an intelligent robot with a variety of external sensors. The intelligent robot is regarded as a family member, through which the control of the digital home is realized. This paper mainly designs the model of the application of intelligent robot in digital home health care. Bluetooth technology is used in the communication between intelligent robot and medical instrument and control pc. The cost of the whole system is low, the function is more comprehensive, the expansion application is very broad, and has great market potential. 2 overall design of intelligent robot 2.1 Multi-sensor system of intelligent robot the most important related field of robot intelligence technology is the integration and fusion of robot multi-sensory system and multi-sensor information [1]. Collectively referred to as the hardware and software part of the intelligent system. The information fusion of vision, hearing, force, touch and other external sensors and the internal sensors of each joint of the robot can enable the robot to complete important functions such as real-time image transmission, speech recognition, scene identification, positioning, automatic obstacle avoidance, target detection and so on. Adding relevant medical modules (ccd, camera, stereo microphone, image acquisition card, etc.) and special medical sensor components to the robot, coupled with the medical expert system, the functions of health care and telemedicine monitoring can be realized. The block diagram of the multi-sensor system of the intelligent robot is shown in figure 1. 2.2 Intelligent robot control system the robot control system consists of two parts: one is the upper computer, which generally uses pc, which completes the tasks of robot trajectory planning, sensor information fusion control algorithm, vision processing, man-machine interface and remote processing. The second is the lower machine, which generally uses multi-single-chip microcomputer system or dsp as the core components of the controller to complete the functions of motor servo control, feedback processing, image processing, speech recognition and communication interface. If the multi-single-chip microcomputer system is used as the lower computer, each processor completes a single task and completes the overall system function through information exchange and mutual coordination, but its signal processing ability is obviously lacking. Because dsp is good at signal processing and often needs signal processing, image processing and speech recognition for this intelligent robot, dsp is used as the controller of the intelligent robot control system [2]. The control system takes dsp (tms320c54x) as the core component, and consists of Bluetooth wireless communication, gsm wireless communication (supporting gprs), motor drive, digital compass, sensory function sensor (vision and hearing, etc.), medical sensor and multiple serial port communication (rs-232) module. The block diagram of the control system is shown in figure 2. The main results are as follows: (1) the motion of the robot is controlled by the driving motor and the steering motor, and the steering motor uses the information of the digital compass as the feedback quantity for pid control. (2) the rokl01007 circuit of ericsson company is used as the Bluetooth wireless communication module to realize the communication between the intelligent robot and the host computer pc and other medical and health care instruments based on the Bluetooth module. (3) the gsm wireless communication module supporting gprs supports data, voice, short message and fax services, and communicates with the remote medical monitoring center by mobile phone. (4) because tms320c54x has only one serial port, and Bluetooth module, gsm wireless module, digital compass and visual and auditory sensor modules all use RS-232 asynchronous serial communication, so it is necessary to design a multi-select serial port communication module for conversion processing. When the tms320c54x needs the data of the Bluetooth wireless communication module, it is gated through the circuit; when the t~ms320c54x needs the data of a sensor module, the strobe of the last wireless communication module is turned off, and the sensor module is gated at the same time. In this way, each module completes the serial communication with 1~ms320c54x. 3 the realization of the main medical and health care functions the intelligent robot can provide the following services for the medical and health care of digital families: (1) Medical monitoring uses medical sensors with Bluetooth module to real-time detect the main physiological parameters of family members, such as ECG, blood pressure, body temperature, respiration and blood oxygen saturation, and provide local results through the robot’s processing system. (2) remote diagnosis and consultation transmit the collected video and audio data combined with various physiological parameter data to the telemedicine center through the visual and auditory functions of the robot, and the experts of the medical center carry out remote monitoring. Combined with the medical expert system for consultation on the health status of family members, that is, to provide services of looking (video), smelling, asking (audio) and cutting (various physiological parameters) [3]. 3.1 Transmission of robot vision and video signal the video signal collected by the robot has two functions: to provide robot vision and to transmit the static and dynamic images of family members to the telemedicine center. The function of robot vision is to obtain the required information from the 3D environment image and construct a clear and meaningful description of the environment object. Vision includes three processes: (1) image acquisition. The 3D environment image is converted into electrical signal by vision sensor (ccd camera of stereo image). (2) Image processing. Image-to-image transformation, such as feature extraction. (3) Image understanding. The description of the environment is given on the basis of processing. Through the transmission of video signals, doctors in telemedicine centers can learn about the physical and mental state of family members in real time. According to the needs of doctors, intelligent robots capture images suitable for health care and diagnosis, and selectively transmit high-resolution and low-resolution images. In the process of health care, there are two different requirements for image transmission: (1) when doctors observe the colors of skin, lips, tongue, nails and facial expressions of family members, they need to transmit static high-resolution color images; the method adopted is to transmit a high-resolution still image at intervals (for example, 5 minutes). (2) when doctors check the body movement ability of family members with the help of dynamic pictures, they can transmit images with lower resolution and smaller size, and the method adopted is reasonable compression and restoration to ensure real-time performance. 3.2 Transmission of robot hearing and audio signals the audio signals collected by the robot also have two functions: one is to provide robot hearing, and the other is that with the help of audio signals, family members can communicate with the doctor. doctors can understand the health status and state of mind of family members. The transmission of audio signal provides a language communication way for doctors to carry out medical care for family members. Robot hearing is a speech recognition technology, and the health care intelligent robot has a variety of sound interaction systems, which can carry out medical testing and monitoring according to the orders of family members. It can also do housework, control digital household appliances and take care of patients according to the orders of family members. A plurality of stereo microphones are used to obtain sound. Because the frequency range of sound is about 300hz-3400hz, too high or too low frequency sound does not need to be transmitted in general, so only transfer the sound in the frequency range of 1000hz-3000hz, doctors and family members can communicate normally, thus the bandwidth occupied by transmitting audio signals can be reduced, and then appropriate communication audio compression protocols can be used to meet the requirements of real-time audio. The auditory system of the intelligent robot is shown in figure 3. 3.3 Collection and transmission of physiological information traditional detection equipment is wired to the human body to collect physiological information, various connections are easy to make patients nervous, resulting in inaccurate data detected. This problem can be well solved by using Bluetooth technology. the medical micro sensor with Bluetooth module is placed on the family members so that it does not interfere with the normal activities of the human body as far as possible. then the collected data is transmitted to the receiving device through Bluetooth technology and processed. A detector with a Bluetooth module is installed on the intelligent robot as a receiving device. Various medical sensors transmit the physiological information data collected to the detector through the Bluetooth module. The detector has two working modes: one is to give the data to the intelligent robot for processing and provide local results. The second is to connect with internet (or send it back directly through gsm wireless module) to achieve the purpose of health care and remote monitoring by transmitting data to the telemedicine center. Video and audio data are also transmitted in this way. The data transmission system of the intelligent robot is shown in figure 4. 4 the application of Bluetooth module 4.1 Bluetooth technology [4] Bluetooth technology is a short-distance wireless communication technology used to replace cable or connection. Its carrier is the worldwide public 2.4ghz (the actual RF channel is fend2402k × 1mhz, 1mhz, 1mhz, 1mhz, 1mhz, etc. , 78) ism frequency band, and uses frequency hopping method to expand the frequency band, the frequency hopping rate is 1600 hops / s. 79 channels with 1mhz bandwidth can be obtained. Bluetooth equipment adopts gfsk modulation technology, the communication rate is 1mbit/s, the actual effective rate can reach 721kbit/s, the communication distance is 10m, and the transmission power is 1mw. when the transmission power is 100mw, the communication distance can reach 100m, which can meet the needs of digital families. 4.2 Bluetooth module rokl01007 Bluetooth module [5] is a wireless baseband module suitable for short-distance communication developed by Ericsson. It has high integration, low power consumption (RF power is 1mw), supports all Bluetooth protocols, and can be embedded in any device that requires Bluetooth function. The module includes five functional modules: baseband controller, wireless transceiver, flash memory, power management module and clock, which can provide functions as high as the hci (host control interface) layer. The structure of a single Bluetooth module is shown in figure 5. The Bluetooth technology supports point-to-point ppp (point-t0-point pro-tocol) and point-to-multipoint communication, and connects several Bluetooth devices wirelessly into a piconet [6]. Each piconet consists of 1 master device (master) and several slave devices (slave), with a maximum of 7 slave devices. The master device is responsible for the action of the communication protocol, and the mac address is represented by 3 bits, that is, 8 devices can be addressed in a piconet (there is virtually no limit on the number of interconnected devices, but only 8 can be activated at a time, of which 1 is a master and 7 are slaves). The slave device is controlled by the master device. All equipment units use the same frequency hopping sequence. The micro medical sensor with Bluetooth module is used as the slave device, and the detector with Bluetooth module on the intelligent robot as the master device. The hardware of master-slave equipment mainly includes antenna unit, power amplifier module, Bluetooth module, embedded microprocessor system, interface circuit and some auxiliary circuits. The master device is the core part of the whole Bluetooth, which is responsible for the conversion and information sharing between different communication protocols, as well as the data exchange function with external communication, and is also responsible for the management and control of each slave device. Conclusion with the progress of society, the development of economy and the improvement of people’s living standards, more and more people need family health care services. The intelligent robot system for digital home health care service proposed in this paper has comprehensive functions, and has a wide range of applications in home intelligent robots, intelligent homes based on Bluetooth technology and digital hospitals. It has great market potential. For more papers, please visit the secretarial hodgepodge website.

Model thesis on Industrial Robotics
Nowadays, with the social and economic development, robots begin to be widely used in various industries to carry out some complex and heavy physical work for workers, which can reduce people’s work burden. The following is a sample paper on industrial robot technology sorted out by me. I hope it can be helpful to everyone!
Industrial Robot Technology thesis Fan Wen part 1: “talking about the Application of Industrial Robot in Industrial production”
Industrial robot is a multi-joint manipulator or multi-degree-of-freedom robot for industrial field. Industrial robot is a machine device that performs work automatically, and it is a kind of machine that realizes various functions by its own power and control ability. It can be directed by humans or run according to pre-programmed programs, and modern industrial robots can also act according to the principles laid down by artificial intelligence technology. The application of industrial robot in industrial production is discussed.
Key words: industrial robot application industry
1 introduction
Industrial robots were first used in the automobile manufacturing industry, often used in welding, painting, loading, unloading and handling. Industrial robot extends and expands the functions of human hands, feet and brain. it can replace people to work in dangerous, harmful, toxic, low temperature, high heat and other harsh environment, and complete heavy and monotonous repetitive work instead of people. improve labor productivity and ensure product quality. Industrial robot, NC machining center, automatic handling trolley and automatic detection system can form flexible manufacturing system and computer integrated manufacturing system to realize production automation.
2 the main application of industrial robots
(1) poor working environment and dangerous work in the military and nuclear industries, some jobs are harmful to human health and life-threatening, or unsafe and unsuitable for human beings to do, industrial robots are the most appropriate. Such as nuclear plant equipment inspection and maintenance robots, boiling water reactor fuel automatic exchanges in the nuclear industry.
(2) the fields of special operation and extreme operation, such as volcanic exploration, deep-sea secret exploration and space exploration, are beyond the reach of human beings, and only robots can carry out operations. Such as the manipulator used on the space shuttle to recover satellites; remote-controlled marine robots for undersea mining and salvage.
(3) the early industrial robots in the field of automatic production were mainly used for machine tool loading, blanking, spot welding and painting. The most widely used manufacturing industries include motor manufacturing, automobile manufacturing, plastic forming, general machinery manufacturing and metal processing. With the emergence of flexible automation, robots play a more important role in the field of automated production. The following is a brief introduction to the application of industrial robots in the field of automatic production.
2.1 Welding robot
Spot welding robot industrial robot is first used in automobile spot welding, and spot welding robot is widely used in welding thin plate parts of car body. Generally speaking, it takes about 3000 to 4000 solder joints to assemble and weld a car body, 60% of which are done by spot welding robots. In some large quantities of automobile production lines, the number of spot welding robots in service is even as high as more than 150.
The main performance requirements of the spot welding robot are as follows: small installation area, large workpiece space, fast completion of multi-point positioning with small pitch, high positioning accuracy (0. 25 mm) to ensure welding quality, weight (490-980N) to carry welding pliers with built-in transformer, simple teaching and man-hour saving
2.2 Arc welding robot
Arc welding robot is used in the welding process of continuous combination of welding metal, most of which can complete automatic wire feeding, melting electrode and gas shielded welding. Arc welding robot has a wide range of applications, in addition to the automotive industry, in general machinery, metal structures and many other industries. The arc welding robot should be a welding system including all kinds of welding accessories, not just a single machine with a welding torch moving at a planned speed and posture. The basic composition of the arc welding robot is shown in figure 1. The main arc welding methods suitable for robot applications are inert grip shielded welding, hybrid shielded welding, submerged arc welding and plasma arc welding.

Fig. 1 basic composition of arc welding robot system
The main performance requirements of the arc welding robot: in the arc welding operation, the welding torch is required to track the bead movement of the workpiece and constantly fill the metal to form the weld bead. Therefore, the speed stability and trajectory are two important indexes in the process of movement. in general, the welding speed is about 5: 50 mm/s and the trajectory accuracy is about. 2 ~ 0. 5) mm; because the attitude of the welding torch also has a certain influence on the weld quality, it is hoped that the adjustable range of the welding torch attitude can be as large as possible while tracking the welding bead. In addition, there are some other performance requirements, these requirements include: setting welding conditions (current, voltage, speed, etc.), jitter function, groove filling function, welding anomaly detection function (arc break, workpiece melting) and welding sensor interface function (initial solder joint detection, weld bead tracking).
2.3 painting robot
Spray painting robot is widely used in spray painting of automobile body, household appliances and all kinds of plastic products. The painting robot has the following characteristics in terms of environment and action requirements:
(1) the air in the working environment contains explosive spray vapors.
(2) it moves at a high speed along the track, and all the points passing through are the work points.
(3) most of the painted parts are carried on the conveyor belt and spray paint as they move. The articulated painting robot is shown in figure 2.
2.4 handling robot
With the development of computer integrated manufacturing technology, logistics technology and automatic warehousing technology, handling robot is more and more widely used in modern manufacturing industry. The robot can be used in the processing of parts, and the loading, unloading, storage and transportation of materials and auxiliary measuring tools can be used to send parts from one conveying device to another, or to remove the machined parts from one machine tool and install them on another machine tool.
2.5 Assembly robot
Assembly plays a very important role in modern industrial production. Relevant statistics show that the amount of assembly labor accounts for 50% to 60% of the labor volume of product production, and on some occasions, the proportion is even higher. For example, in the chip assembly and circuit board production of the electronic device factory, the assembly labor accounts for 70% ~ 80% of the production labor. Therefore, it is very important to use robots to realize automatic assembly operations.
2.6 Robot flexible assembly system
The robot officially entered the field of assembly work around 1980, around the first year of the popularity of robots. In the early days, the robot was mainly used to replace the manual work on the assembly line, and then the assembly line with robot as the main body appeared soon. The application of assembly robot has greatly promoted the progress of assembly production automation. The flexible automatic assembly system established by the assembly robot can automatically assemble small and medium-sized and moderately complex products, such as motors, pump gearboxes, etc., which is especially suitable for the assembly of small and medium-sized batch productions. it can realize automatic loading and unloading, transmission, detection, assembly, monitoring, judgment, decision-making and other functions.
Robot flexible assembly system usually takes the robot as the center, and has many peripherals, such as parts supply device, workpiece conveying device, fixture, smear and so on. However, if there are too many kinds of parts, the whole system will be too large and the efficiency will be reduced, which is not desirable. In the robot flexible assembly system, the number of robots can be selected according to the output, while the peripherals such as parts supply devices depend on the types of parts and jobs. Therefore, compared with the assembly line, the less the output, the greater the investment of the robot flexible assembly system.
3 concluding remarks
Industrial robot is a kind of system technology based on the technology of mechanical, electronic, electronic computer and automatic control and other disciplines; it can also be said to be a knowledge-intensive, technology-intensive, interdisciplinary and integrated high and new technology. With the progress and development of these related disciplines and technologies, industrial robot technology will certainly develop and improve rapidly.
The second part of the model paper on industrial robot technology: “discussing the development trend of industrial robot”
With the development of social economy, robots have been widely used in various industries to carry out some complex and heavy manual work for workers. At present, robot is a typical representative of manufacturing and automation equipment, which will be the “ultimate” version of man-made machines. Its application has involved many disciplines and fields, such as information, automation, intelligence, sensor and knowledge. at present, it is the best integration of high-tech achievements in our country and even in the world. Its development is closely related to the development of many disciplines. According to the current development trend, the scope of application of industrial robot is more and more extensive, at the same time, in the technical operation, it has become more and more standardized and standardized to improve the safety of industrial robot. On the other hand, the development of industrial robot is becoming more and more miniaturized and intelligent, and it is more and more widely used in human life.
Key words Safety in the field of intelligent application of industrial robots
With the complex needs of society, industrial robots are more and more widely used in the field of application. On the one hand, industrial robots are widely used in industrial production to replace workers’ dangerous, complex and monotonous long-time operations, such as mechanical processing, pressure casting, plastic forming and metal products industry. at the same time, it is also used in high-risk sectors such as the atomic energy industry, which has been widely used in developed countries. On the other hand, industrial robots are also widely used in other fields. with the rapid development of science and technology, the performance and safety performance of industrial robots have been improved. The scope of application has broken through the industry, especially in the medical industry.
I. the development of industrial robots
The first generation robot generally refers to the programmable robot and remote control manipulator which are widely used in industry. The programmable robot can complete some simple and repetitive tasks according to the program compiled by the operator. The remote control operation mechanism depends on the operator to send out every step. In 1982, General Motors of the United States equipped the robot with a vision system on the assembly line, thus announcing the advent of the second generation of robot-perceptual robot. This generation of robots, with external sensors, can be programmed offline. With the support of the sensor system, it has the function of perceiving the environment to varying degrees and correcting the program itself. The third generation robot is an autonomous robot, which is being developed and developed in many countries. It not only has the perception function, but also has the ability of decision-making and planning. Be able to make decisions and plan actions according to people’s orders or according to the environment, that is, programming according to tasks.
Robot research in China started relatively late. Since the beginning of the “Seventh five-year Plan”, the state has invested money to tackle key problems of industrial machinery and its parts, and completed the research and development of a complete set of teaching and reproducible industrial robot technology. The national high-tech research and development plan began to be implemented in 1986, and the intelligent robot theme tracks the forefront of robot technology in the world. After several years of research, a large number of scientific research achievements have been achieved, and a number of special robots have been successfully developed.
Industrial robot in China started in the early 1970s. After more than 30 years of development, it has roughly experienced three stages: the embryonic period in the 1970s, the development period in the 1980s and the applicable period in the 1990s.
The 1970s was a milestone in the world’s scientific and technological development: man landed on the moon and achieved the soft landing of Venus and Mars. Our country has also launched man-made satellites. The application of industrial robots has set off one of the most exciting parts of the world, especially in Japan, which complements the growing shortage of labor. Under this background, our country began to develop its own industrial robot in 1972.
After entering the 1980s, under the impact of the high-tech wave, with the deepening of reform and opening up, the development and research of robot technology in China has been valued and supported by the government. During the Seventh five-year Plan period, the state invested money to tackle key problems of industrial robots and their parts, completed the development of a complete set of technology for teaching and reproducing industrial robots, and developed spraying, spot welding, arc welding and handling robots. The National High Technology Research and Development Program (863 Program) began to be implemented in 1986. Intelligent robots track the forefront of robot technology in the world. After several years of research, a large number of scientific research achievements have been achieved, and a number of special robots have been successfully developed.
Since the early 1990s, China’s national economy has entered two periods of fundamental transformation, setting off a new round of economic system reform and technological progress. China’s industrial robots have taken a big step forward in practice. Industrial robots for various uses such as spot welding, arc welding, assembly, spray painting, cutting, handling, packaging and palletizing have been developed, and a number of robot application projects have been implemented. A number of robot industrialization bases have been formed, which has laid the foundation for the take-off of China’s robot industry.
China’s industrial robots have made great progress through the support of the Seventh five-year Plan, the Ninth five-year Plan and the 863 Plan, and the industrial robot market has become mature and has been widely used in various industries.
The key points of the development of industrial robot technology in China in the future are as follows: first, dangerous and harsh environment working robots: mainly anti-riot, high-voltage electrified cleaning, planet detection, oil and steam pipelines and other robots; second, medical robots: mainly brain surgery auxiliary robots, remote control operation auxiliary bone correction robots, etc.; third, bionic robots: mainly mobile robots, network remote control operation robots and so on. Its development trend is intelligence, low cost, high reliability and easy integration.
Second, the development trend of industrial robots
Robot is a typical representative of advanced manufacturing technology and automation equipment, and it is the “ultimate” form of man-made machines. It involves many disciplines and fields, such as machinery, electronics, automatic control, computer, artificial intelligence, sensor, communication and network, etc., and is a comprehensive integration of a variety of high-tech development achievements, so its development is closely related to the development of many disciplines. Nowadays, the main development trends of industrial robots are as follows: first, the performance of industrial robots continues to improve (high speed, high precision, high reliability, easy operation and maintenance), while the price of a single machine continues to decline. Second, the mechanical structure is developing towards modularization and reconfiguration. For example, the servo motor, reducer and detection system in the joint module are integrated; the joint module and connecting rod module are reorganized to construct the robot. Third, the industrial robot control system develops to an open controller based on PC, which is convenient for standardization and networking; the device integration is improved, the control cabinet is becoming smaller and smaller, and the modular structure is adopted, which greatly improves the reliability, ease of operation and maintainability of the system. Fourth, the role of sensors in robots is becoming more and more important. in addition to the traditional position, speed, acceleration and other sensors, vision, force, sound, touch and other multi-sensor fusion technology has been maturely applied in the product system. Fifth, robotic machinery began to rise. Since the “virtual axis machine tool” was developed in the United States in 1994, this new device has become one of the hotspots of international research, and has explored and opened up its practical application fields.
The overall trend is to transfer from the concept of robot in the narrow sense to the concept of robot technology in the broad sense, and from the industrial robot industry to the robot technology industry of solution business. The connotation of robot technology has become an intelligent system with practical action function and flexible application of robot technology. The structure of the robot is becoming more and more dexterous, the control system is getting smaller and smaller, its intelligence is getting higher and higher, and is developing in the direction of integration.
III. Challenges and prospects for the Development of Industrial Robots in China
China’s industrial foundation is weak, and the development of industrial robots has been in a preliminary stage. Although our country began to develop industrial robots in the 1970s, there is a lack of technical strength and the technological blockade of western countries. In the process of development, there are many problems. Broken down, there are the following points:
First of all, the manufacturing capacity of basic parts in our country is poor. Although China has a certain foundation in related parts, there is a large gap between China and foreign countries in terms of quality, comprehensive product range and batch supply. Especially in the high-performance AC servo motor and precision reducer, the gap is particularly obvious, resulting in the import of key parts, affecting the price competitiveness of robots in our country.
Second, China’s robots have not yet formed their own brand. Although there are a number of enterprises engaged in the development of robots, they have not formed a large scale, lack of brand recognition in the market, and have been facing the crackdown of foreign robot brands in the robot market. As a mature industry, foreign robots adopt the whole machine price reduction to attract domestic enterprises to buy, while in the follow-up strategy of high cost of maintenance spare parts, gradually occupy the Chinese market.
Third, there is a lack of awareness and few policies to encourage industrial robot products. The manufacturing and application level of industrial robots represents the manufacturing level of a country. We must understand the importance of developing China’s industrial robot industry from a national perspective, which is an important means and way for China to transform from a big manufacturing country to a manufacturing power. □

Model article 3 of industrial robot technology paper: “on the mechatronics of industrial robot”
1 the application status of mechatronics technology
1.1 Industrial robots.
The emergence of industrial robots can replace human labor to a certain extent. Industrial robots are an ideal choice for workplaces with high radiation, high noise pollution and high concentration of harmful gases. The development of industrial robots has gone through three stages. the first generation of industrial robots have a low degree of intelligence and can only carry out simple repeated movements through preset programs, which can not cope with the ever-changing working environment and jobs. With the development of science and technology, on the basis of the first generation robot, through the application of various sensors, it can carry out some adaptive work through the acquisition, analysis, processing and feedback of environmental information to the action unit. although the degree of intelligence of this kind of robot is low, it has been successfully applied in some specific fields. Today, when the mechatronics technology is relatively mature, the intelligent level of the third generation robot has been greatly improved. It can collect information and data through powerful sensors, and make judgments similar to the human brain according to the actual situation. Therefore, it can work independently in a variety of environments, but the cost is high, which limits the practical application to a certain extent.
1.2 distributed control system.
Compared with the centralized control system, the distributed control system controls and directs multiple computers responsible for field measurement and control through a central computer. Because of its powerful function and security, it has become the mainstream technology of the current large-scale mechatronics system. According to the actual situation, the level of the distributed control system can be divided into two levels, three levels or more, and the real-time monitoring, management and operation control of the field production process can be completed by the central computer. At the same time, with the continuous development and innovation of measurement and control technology, the distributed control system can also realize the functions of real-time scheduling, on-line optimization, statistical management of production plan and so on. It has the advantages of rich functions, high reliability, convenient operation, low failure rate, easy maintenance and expandability, so the reliability of the system is greatly improved.
2 the development trend of mechatronics technology
2.1 artificial intelligence.
Artificial intelligence is to make industrial robots or CNC machine tools simulate the intelligence of the human brain, so that they have a certain ability of reasoning and judgment, logical thinking and independent decision-making in the production process, which can greatly improve the degree of automation of the industrial production process. Even the realization of real unattended is of great significance to reduce labor costs and improve processing accuracy and work efficiency. At present, artificial intelligence has not only stayed in the concept, so it can be predicted that mechatronics technology will develop in the direction of artificial intelligence. Although it is impossible for robots or CNC machine tools to have the human mode of thinking and intellectual characteristics at the current level of science and technology, in industrial production, making these mechatronics equipment have some human functions can be achieved through advanced technology.
2.2 networking.
The development of network technology provides convenient conditions for remote monitoring and remote control of mechatronics equipment. Therefore, the combination of network technology and mechatronics technology will be the focus of the development of mechatronics technology. In the process of production, operators need to walk back and forth in the workshop, master the status of the equipment, and operate the operation panel of the machine tool. By establishing a communication protocol between the mechatronics equipment and the control terminal, and realizing the transmission of information and data through optical fiber and other media, remote monitoring and operation can be realized, the amount of labor of workers can be reduced, and various functions of the control system can be realized. Theoretically, it is based on network technology.
2.3 Environmental protection.
In the recent decades of the development of human society, although the economy has developed rapidly and people’s living standards have been significantly improved, however, the development model at the expense of resources and environment has seriously polluted the environment on which human beings depend for survival. therefore, with the sustainable development strategy put forward today, the development of any technology should be based on the premise of being friendly to the environment, otherwise there will be no future. Therefore, ring preservation is the inevitable trend of the development of mechatronics technology. In the process of mechatronics application, through the efficient use of resources and achieving standard emissions or even zero emissions in the manufacturing process, the products have no impact on the ecological environment in the process of use. even after scrapping, it can also be effectively recycled, which is the specific form of environmental protection of mechatronics technology, which meets the requirements of sustainable development.
2.4 Modularization.
As there are many manufacturers of mechatronics devices, modularization will be a very promising research direction in order to reduce the cost of system upgrading and provide convenience for maintenance. Through the modular transformation of the functional unit, the corresponding functional module can be directly assembled or replaced when the function needs to be added or changed. even if there is a failure, only the damaged module can be replaced, and the work efficiency is extremely high. the enhancement of versatility saves a lot of costs for enterprises.
2.5 built-in energization.
Mechatronics has higher requirements for electric power, if there is no sufficient power supply, it will affect the production efficiency, even due to the loss of data caused by power outage, so the power supply can always be maintained through the equipment-equipped power energy system. to make the system run more smoothly.
3 conclusion
To sum up, the application of mechatronics technology can greatly improve the production efficiency and precision of products, and has greater technical advantages in the current industrial production. I believe that with the development of science and technology, the technical level of mechatronics will also be continuously improved. to make greater contributions to industrial production.
