[0002] A picking robot arm is an automated equipment. Its main function is to grab, carry and place objects to realize automated material handling and transportation. The picking robot arm controls the movement of the robot arm so that it can accurately grab and place objects within a specific spatial range, thereby improving work efficiency and reducing manual labor. With the continuous development of science and technology, automation technology has been widely used in various fields. In the fields of logistics and warehousing, the emergence of automated picking robot arms has greatly improved work efficiency and accuracy. Existing picking robot arms are usually composed of a robot body, a driver and a control system. When in use, the driver is started and stopped by a controller to drive the robot arm to work.
