In our country at present is often used in the finished work of manipulator are: injection industry from the mold to grab products and fast teleport to the next will product production processes; Manipulator processing industry for picking, feeding; Casting industry used to extract high-temperature solution, etc.We can achieve this kind of job of carrying manipulator as the research object, familiar with the kinematic principle of carrying manipulator.On this basis, it determines the basic system structure carrying manipulator of the manipulator, completed the design, including the automatic control system, pneumatic systems, hand and wrist, arm a
