Design of a PWM Programmable Controller for Cartesian Coordinates Robot

This paper presents a desing of a PWM programmable controller for industrial robot to be utilized in process which reqires various movements and repeating operations. To be specific, a low-level robot language is constructed which makes easy for the user to program complex robot motion, and an interpreter is developed to execute the program. Also, related hardware and software, and monitor program for convenience of user are implemented. When the proposed controller is applied to the catresian coordinate 4-axis manipulator, it reveals that the error probabilities of X,Y and Z axis as 0.033%, 0.023%,0.028% respectively.
