POINT MEASURING PROCESS FOR PRESET ROBOT

A process for controlling an industrial robot in which most data for controlling the robot can be supplied using a preset process without moving the robot and only data for regions in which very precise control is required need be prepared by actually moving the robot. A programming unit is provided separate from but connectable to a robot control unit. The programming unit is used to compile and transfer completed programs to the robot control unit for controlling the movements of the robot. To program the robot control unit, the programming unit and robot control unit are connected as an on-line system. Then, data describing a desired path of movement is inputted to the programming unit as a series of coordinates in Cartesian form. In regions where very precise control is required, the coordinates describing the desired path of movement are corrected using small corrective motions of the robot. The inputted data and the corrected coordinates are displayed.
