Abstract: In this paper,an intelligent robot simulation system is introduced.It includes robot kinematics and ts inverse problems,trajectory planning,workspace determination,collision and interferences detectiongraph generation and processing,and animation technology.Artificial intelligence technoloty is used toderive the formulae of robot kinematics and inverse solutions.Assembly algorithms are used to input3-D graphs,and fast and efficient algorithms for 3-D dynamic graphs are presented.It is appropriate tothe purpose of real time graph simalation of robot.The programs are written in Turbo-pascal and imremented on IBM-PC/XT.
