The easiest to use a robot?
AGV belongs to industrial handling robot, which is equipped with automatic guidance device, controlled by computer, and has the functions of movement, automatic navigation, multi-sensor control, network interaction and so on. The demand field of AGV robot is relatively concentrated, which is mainly used in industrial manufacturing and intelligent warehousing to improve logistics efficiency.
It can be said that AGV handling robot is one of the most widely used industrial robots. AGV handling robot can be seen in industrial manufacturing, warehousing and logistics, tobacco, medicine, food, chemical and other industries. It is widely used in the production process to solve the problems of handling, out of storage, storage and other problems, so that the production process is more smooth.
The main characteristics of AGV handling robot are:
1. Efficient handling operations can be carried out
Through the integration of AGV handling robot and other equipment, the original tedious handling work can be realized by AGV robot, which greatly improves the efficiency of factory logistics transportation, saves a lot of labor for enterprises, and greatly improves the automation level of enterprises.
Second, cooperate closely with the production line
In the production operation, raw materials, semi-finished products and finished products are usually transported point-to-point frequently, which puts forward high requirements for the cooperation between the AGV handling robot and the production line. In the process of practical application, we should not only have a certain allocation in the time interval, but also have higher requirements in the time to complete the transportation.
Third, tailor-made for enterprises
The production scenarios of different enterprises are very different, which requires the AGV program to be tailored according to the production process of the enterprise, according to the relevant production site or setting environment, as well as the characteristics of product processing. Through rich project experience, Miklimei has optimized and modified the structure of AGV handling robot, and has formed the company’s standard AGV product library to meet the AGV handling robot with high precision, good stability and strong environmental adaptability that can be used by most customers.
Material handling is a daily work that can be seen everywhere, which exists in various industries, but behind the seemingly inconspicuous simple work, there is a long-term and basic enterprise demand, and it is often limited by personnel, cost, efficiency and other factors. in this case, AGV handling robot brings better economic benefits for enterprises by improving transportation efficiency and transportation quality and saving labor costs.
How to choose AGV handling robot?
AGV handling robots are generally non-calibrated, to be clear about their own needs and conditions of use, and then consult with regular manufacturers. Reference source

What is the structure of a small mobile robot?
So far, the driving mechanism of ground mobile robot is mainly divided into three types: track type, leg type and wheel type. Each of the three driving mechanisms has its own characteristics [2].
(1) track
Crawler first appeared on tanks and armored vehicles, and later appeared on some robots driving on the ground. it has good stability, obstacle performance and long service life, so it is suitable for driving on rugged ground, but when the ground environment is bad, the crawler will soon be worn out or even worn out, the heavy crawler and a variety of drive wheels make the whole mechanism bulky and consume relatively large power. In addition, the crawler mechanism is complex, so it is very difficult to analyze the motion and design the autonomous control.
(2) leg style
The leg mechanism has excellent off-road ability, which has been widely valued by robot experts and achieved great results. According to the number of legs, there are various driving structures such as three legs, four legs, five legs and six legs. Here we briefly introduce a typical six-legged mechanism.
In general, the six-legged mechanism uses the way of changing the supporting legs to transfer the overall center of gravity from one leg to the other, so as to achieve the purpose of walking. The walking principle is as follows: when at rest, the robot is supported by six legs. When it is necessary to move, three of the legs are lifted into free legs (the ends of the legs form triangles), and the center of gravity of the robot is supported by Chen bars, and then the free legs move forward, and the distance and orientation of movement are planned by the computer. however, it is necessary to ensure that the ends of the free legs form triangles when landing. Finally, the supporting leg moves forward, and the center of gravity gradually shifts from the supporting leg to the free leg, when the free leg becomes the supporting leg, and the supporting leg becomes the free leg, thus completing a walking cycle.
Legged robots, especially six-legged robots, have strong cross-country ability, but the structure is more complex, and the walking speed is slow.
(3) wheeled
The wheeled robot has the advantage of high speed, but the cross-country performance is not very strong. Nowadays, many wheeled structures have been different from the traditional wheeled structures. with the emergence of a variety of wheel chassis, the combination of wheeled and leg structure has been realized, which has the ability to surmount obstacles comparable to the leg structure. Nowadays, the focus of the research on the robot mechanism has shifted to the wheel-leg mechanism.
The mobile robot designed in this paper is not only required to have the characteristics of fast moving speed and simple control of the general wheeled robot, but also has a better ability to surmount obstacles, so this paper chooses the wheel-leg mechanism with the combination of wheel and leg as the driving mechanism.
2.1.2 Choice of driving form
The driving part is an important part of the robot system, and the commonly used driving forms of the robot are hydraulic drive, pneumatic drive and electric drive.
(1) hydraulic drive
The hydraulic drive uses high-pressure oil as the medium, the volume is smaller than the air pressure drive, the ratio of rate to mass is large, the drive is stable, and the inherent efficiency of the system is high, and the speed regulation is good. At the same time, the hydraulic drive speed regulation is relatively simple, and can realize stepless speed regulation in a wide range. However, due to the high pressure, there is always the danger of oil leakage, which not only affects the working stability and positioning accuracy, but also pollutes the environment, so good maintenance is needed to ensure its reliability. The advantage of hydraulic drive over motor is its own safety. because the motor has the possibility of arc and detonation, the voltage in the explosive area should not exceed 9V, but there is no arc problem in the hydraulic system.
(2) Air pressure drive
Of all the driving modes, pneumatic drive is the simplest. The operating pressure is usually in 0.4~0.6Mpa, up to 1Mpa. It is difficult to use pneumatic servo to achieve high precision, but in the case of meeting the precision, pneumatic drive is the lightest and lowest cost of all robot driving forms. The main advantage of pneumatic drive is that the gas source is convenient, the driving system has buffering effect, simple structure, low cost, and can work in harsh environments such as high temperature and dust. The disadvantage is that the power-to-mass ratio is small, the volume of the device is large, and the pose accuracy of the robot is not high because of the compressibility of the air.
(3) Electric drive
Electric drive uses the force or torque produced by various motors to drive the load directly or through the deceleration mechanism, which reduces the intermediate link from electric energy to pressure energy, and directly obtains the required robot motion. Electric drive is one of the most commonly used driving methods for robots at present. It is characterized by easy control, high motion precision, fast response, easy to use, large driving force, convenient signal monitoring, transmission and processing, low cost, high driving efficiency, no environmental pollution, and can adopt a variety of flexible control schemes.
