<p>A controller in a robot control system creates a workpiece master image and robot operation program. When there exists a next workpiece to be processed on the basis of the same robot operation program, the controller acquires a master image and a robot operation program for the next workpiece, captures an image of a welding point on the next workpiece on the basis of a workpiece robot operation program, compar es information on the master image and the captured image of the welding point on the next workpiece, and acquires a position on the image of the welding point on the next workpiece corresponding to a welding point in the master image. Then, the controller displays images simultaneously showing positions corresp onding to welding points in the master image collectively for each welding point on the image of the welding point on the next workpiece. When an operato r finds that correction is needed for the collectively displayed images and inst ructs that a position corresponding to a welding point in the master image be corrected, the controller corrects the position corres ponding to the welding point in the master image according to the correction inst ruction.</p> |
