At the same time there have been some new production activities in these production activities, there is a high risk of bodily harm greater in some areas unfit for human work, the robot is just to adapt to such work. In todays large-scale manufacturing enterprises to improve production efficiency, ensure product quality, attention to the production process in general the degree of automation, industrial robots, automated production line as an important member of gradually being recognized and adopted by enterprises. Industrial robot technology and applications to some extent, reflect the extent of a countrys level of industrial automation, at present, industrial robot is mainly responsible for the welding, coating, handling and stacking, and labor intensity greatly repetitive work, work Way to teach the general way of reproduction. Robot is modeled on the part of s
