In particular, made the detailed design about base, arm, and end effector and the control system etc. including Total design, waist’s construction design, the arm’s construction design, the wrist’s construction design, the end effector’s construction design, and the drive system of manipulator. At the same time, analysis and compute the hydraulic pressure system and control system. Deeply design the manipulator’s control system, which based on PLC. After analysis about the craft process and the requests of the manipulator, the hardware circuit and the control program of the manipulator then is designed. In a word, the design of the manipulator has come to the anticipant object.
