With the development of modern science and technology, industrial arm is a kind of high-tech automatic intelligent mechanical production equipment developed in recent decades. In the modern production process, Arm robots are widely used in automatic production lines, the research and production of robotic arm machine has become a new technology rapidly developed in the field of high technology, to better realize the organic combination of mechanization and automation, the mechanization and automation organic combination will be better achieved. The biggest difference between the robot arm and the human arm lies in its flexibility and endurance. The biggest advantage of the automatic manipulator is that it can do the same action repeatedly without fatigue. Therefore, industrial arm robot has been paid attention to by many industries and has been used more and more widely.
