Control System Design of 4-DOF Robot Arm Based on LabVIEW

This paper presented a solution of control system of 4 DOF robot arm which is used in materials handling system,and discussed about the working principle and design of the system in detail.With this design,not only the structure of robot arm becomes compact and simple,but also the weight is dropped;at the same time,the output power to do work is increased relatively.The robot arm is mainly designed with a simple and efficient wire driving structure so that all driving components could be configured on the fixed base which is far away from the relative joints.
