The electromechanical system that simulates the action of human hand and arm works according to the principle of electromechanical coupling and the principle of master-slave. Therefore, it is only an extension of human hand and arm, without independent ability. It is attached to the host equipment, and it is an operating device with simple action, fixed operating procedures and constant positioning points. Industrial robots are widely used in industrial production, mainly in the following aspects:

① Realize single machine automation: automatic loading and unloading of various semi-automatic machine tools.

② Composition of automatic production line: on the basis of single machine automation, automatic loading, unloading and conveying of workpieces can make some single machines connected into automatic production lines.

③ Special working environment: such as high temperature (heat treatment, forging, casting, etc.), toxic and harmful, interstellar exploration, seabed resource development and other environments, the manipulator (or automatic or remote control) is used to replace the human.
