Industrial robots are mainly composed of human hands and arms, which can replace the heavy labor to realize the mechanization and automation of production. It can operate in harmful environment to protect personal safety. Therefore, it is widely used in machinery manufacturing, electronics, light industry and atomic energy. department. The world's high-end industrial precision manipulators have a trend of high refinement, high speed, multi-axis and light weight.

　　The traverse robot is mainly expanding its application range in China, focusing on the development of precision manipulators for casting and heat treatment to reduce labor intensity and improve working conditions. While applying special traverse robots, we should develop their general precision manipulators, when we have the support, teaching robots, computer control robots and combination robots with increasing speed, decreasing impact and correct position are all necessary in order to better play the role of the manipulators.

        The development trend of foreign machinery numbers is to vigorously develop robots with some kind of intelligence, which enables it to have a certain sensing ability, and get feedback changes in external conditions, making corresponding changes. If there is a slight deviation in position, it can be corrected and self-tested, focusing on the study of visual and tactile functions. At present, certain achievements have been made.

　　The world's high-end industrial precision manipulators have a trend of high refinement, high speed, multi-axis and light weight. The positioning accuracy can meet the requirements of micron and sub-micron, the running speed can reach 3M/S, the mass production products reach 6 axes, and the total weight of the product system with load 2KG has exceeded 100KG.

     With the miniaturization and miniaturization of manipulators, their application fields will break through the traditional mechanical field. The traverse robots need hard power in precision manipulators to develop the high-end industries such as electronic information, biotechnology, life sciences and aerospace so as to meet the requirements of the times.
