Abstract: In this paper,a method of lowering dimension is adopted to change five-dimension interpolation into five two-dimension interpolation for solving the problem of five-dimension interpolation with the associated running of the five joints of the robot,so the control for the track of its movement is simplified.The designed and practiced robotics control system with five DOF can guide the robot to confirm and define the position coordinate of the point in space by running in manual teaching pattern,it can also run automatically in step way or in continued way by using the robotics language defined in this control system.

Key words: robot, degree of freedom, joint
