装配机器人（Assembly robot） Present situation and development trend of assembly robot Robot technology is the combination of computer control theory, mechanism, information and sensor technology, artificial intelligence, bionics and other subjects formed, its essence is the comprehensive perception, decision-making, action and interaction of the four technologies, contemporary research is extremely active, with increasingly wide field. The level of robot application is an important symbol of the national industrial automation level. At present, the field of robot application is mainly concentrated in the automotive industry, accounting for 28.9% of the total number of robots available. Followed by electrical manufacturing, accounting for about 16.4%, while the chemical industry accounted for 11.7%. In addition, industrial robots in food, pharmaceutical, equipment, aerospace and metal processing and other aspects also have more applications. With the development of industrial robot, its application field began to expand from manufacturing to non manufacturing industry, at the same time in the original manufacturing industry is in deep penetration continuously, to large, thin, soft, narrow, thick, hard processing field deepening, expansion. The application field of new wood furniture, animal husbandry and fishery, buildings, bridges, medical, office, household education research and some other non manufacturing field limit. Now, the types of industrial robots are welding robots, carrying robots, spray painting robots, glue spreading robots, assembly robots, cutting robots, detecting robots and cleaning robots. Generally speaking, a robot system can be divided into five parts according to its function: (a) mechanical body: internal support structure including airframe, frame, mechanical connection, etc.. B) power part: including power supply, motor and other actuators and its drive circuit. C) sensing devices: sensors and their corresponding signal detection circuits. D) con
