In recent years, with the development of industrial automation manipulator gradually become a new subject, and with the rapid development. Manipulator widely application and forging, stamping, forging, welding, assembling, handling, spray paint, heat treatment, etc. Especially in heavy, high temperature, toxic and dangerous, radioactive, dust and so on bad work environment, manipulator because of its significant advantages by pay special attention to. In a word, the manipulator is to improve the labor productivity, improve working conditions, reduce labor intensity and realize industrial production automation is an important means. This design based on PLC describes the manipulator control system design, introduced the manipulator control system, the hardware selection method, the software design process, and the working process of the PLC control device. The design and implementation of the manipulator in the handling assembly line, manipulator controlled by the S7-200PLC complete conveyor belt carrying objects from
