Abstract
A tool mounted on the wrist end of a robot is placed in a predetermined photographing position, and the front and side faces of the tool are photographed by cameras to obtain three-dimensional shape data of the tool. The extent of deformation of the tool is detected by comparing the obtained shape data and reference shape data, and a programmed movement path for the robot is corrected depending on the extent of deformation.
