In this paper, an overall robot design, bined with production practice and theory to determine the structure of the manipulator and the action process, coordinate types and degrees of freedom, and lists the technical parameters of the manipulator. Designed a manipulatordriven program, control program, control program during the selection of different options when paring the advantages and disadvantages, and finally determine the specific control program. Manipulator control device during the selection, the control device on a detailed analysis of options, such as the specific selection step motor parameters. Finally, the use of programmable logic controller to control the manipulator, taking account of the principles of PLC and process of selection, and draws out the external wiring diagram of PLC. Programmable Logic Controller in use when the work is divided into two kinds of manual and automatic mode, and the mapping of the automatic work order function map.
