Research On The Fischer Education Robot Based On PLC

With the rapid development and extensive application of robot,the education robot is recognized by scientific research department and university. The paper using Fischer model as a platform designs and develops an education robot——3-DOF manipulator. First the paper analyzes the gross structure of the manipulator and confirms driving and transmission program, and then it builds up the manipulator in accordance with modular design method. At last the paper researches the control system of the manipulator. The paper focuses on control system. Control system adopts a distribute control system and contains two parts of field control system and PC monitor system. Field control system adopts PLC and PC as industry computer. It allocates PLC I/O points from hardware and compiles the manual and automatic ladder program from software. Based on the PLC communication protocol and VB software a simple and practical monitoring software is compiled and remote operating the manipulator is realized.
