More and more industrial robots are used in industrial production, especially in automobile, metal products, batteries, rubber and plastics industries. With the improvement of performance and the clarity of various application scenarios. At present, high precision, high efficiency and intelligent level determine the development and use of industrial robots. For example, many robots in Japan use high precision resistors to design reasonable optimization circuits to improve precision and sensitivity of robots.
 

 

In addition, as a precision resistor and a precision speed reducer of the core component of the industrial robot, the speed reducer of the robot has the characteristics of short drive chain, small volume, large power, light weight and easy control as compared with a universal speed reducer.
The precision speed reducer enables the robot servo motor to operate at a proper speed, and accurately reduces the rotating speed to the required speed of various parts of the industrial robot, and improves the rigidity of the mechanical body and outputs a larger moment.
 

 

The cost of reducer accounts for about 35% of the cost of robots. The other side is the use of precision resistors. Although the cost of research and development is not very high, it is also the main level of scientific and technological competition in the production of industrial robots. It is also the key factor restricting the development of robot industry. The development of many resistance technologies and precision resistors is almost monopolized, the robot technology and related supporting technologies is crucial. These R & D costs can reach 40% to 50% of the ontology.
 

 

Moreover, RV reducer and harmonic reducer are widely used in joint robot at present. The RV reducer is usually placed in the seat, arm, shoulder and other heavy loads, that is, mainly used for robot joints above 20 kg, while the harmonic reducer is placed on the small arm, wrist or hand, that is, robot joints below 20 kg. What is more, planetary reducer is generally used in rectangular coordinate robots.
 
The use of reducer requires accurate current signals, which are important technical levels in the development of industrial robots.
Take the high-precision resistor as an example, at present, the production technology is all in the top resistance production companies in the world, and many high-precision resistors need to be specially customized in the production of robots. These are also important bottlenecks in the development of robots.
