Research On The Control System Of A Playback Teaching Robot

This paper introduced the teach and playback control system of a five degree of freedom teaching robot,including system compose,design principle and development process of its software and hardware system. The robot can be taught one time but be played back exactly for many times.The control system is a kind of hierarchical control system,which is composed of teach box,main microcomputer and hypogenous microcomputers. The teach box is made up of LCD and film keys,which makes the operation easy and convenient;while the main microcomputer control system makes the communication between the teach box and hypogenous microcomputer possible and carries out teach and playback function. The servomotors are under the control of hypogenous microcomputers.Experiments proved that the robot can run smoothly and the control system has high control precision,which is good enough for teaching.
