摘要

 机械手是一种能模拟人的手臂的部分动作，按预定的程序、轨迹及其它要求，实现抓取、搬运工件或操纵工具的自动化装置。而可编程控制器（ＰＬＣ）由于其具有的高可靠性、编程方便、易于使用和修改，易于扩展和维护，环境要求低、体积小巧，安装调试方便，在工业控制中有着广泛的应用。本设计采用西门子S7-200系列PLC作为控制机对机械手进行控制及监控。

Abstract
     The manipulator is one kind can simulate person's arm's partial movements, according to the predetermined procedure, the path and other requests, realizes the capture, the transporting work piece or operates tool's automated installment. But programmable controller (PLC), because it has the redundant reliability, the programming convenient, easy to use and the revision, easy to expand and the maintenance, the environment requests, the volume to be exquisite lowly, the installation and trial run to be convenient, has the widespread application in the industrial control. This design uses Simens S7-200 series PLC to carry on the control and the monitoring as the cybertron to the manipulator.
