Especially with the improvement of the structure of the machine, the maturity of pneumatics and hydraulics, and the constant improvement of the control element such as the singlechip, PLC, the motion controller, and soon, and the ceaselessly ameliorative and innovative control mode, the precision, delicacy and reliability of the manipulator has been improved expressly, which contributed to alleviating the worker’s labor intensity and difficulty, boosting the working efficiency and quality, reducing cost, as to play an extremely important part in the development and income of the corporations. The subject is a practical item where the mechanics and electrics are integrated very closely. The writer has made a necessary discussion in the application of PLC, the optimize of mechanical structure and the study of control mode and researches into the mechatronics. the writer summarizes the whole thesis and points out the amelioration, perspective and developing direction of the manipulator. Key Words: manipulator, the hydraulic pressure drive, PLC(Programmable Logic Controller) 目录 第1章 绪论 1 1.1 工业机器人（机械手）的概述 1 1.1.1 工业机器人的发展 1
