Abstract
An image of a workpiece is taken by a CCD camera, which includes a view field covering a supply range of the workpiece, and is transmitted to an image processor to detect the position and posture of the workpiece. A robot controller controls a robot to approach a position from another position based on the result of the detection. Then, a measurement using a laser sensor is started. Scanning laser beams projected from an emitter are detected by a light detector and the detected data are analyzed by the image processor. When the robot reaches a third position, the measurement is terminated. The laser sensor may be of a split-light-projection type. For the approaching movement, the image taken by the camera is displayed on a display device to perform a jogfeed of the robot on the screen.
