Abstract
A gripping device on an industrial robot is provided with a plurality of light-emitting members for generating a plurality of light beams that intersect at predetermined angles, and with a plurality of light-receiving elements for receiving the light beams. When the gripping device moves relative to an object that is to be gripped, the object intercepts the light beams, on the basis of which the position of the object relative to the gripping device is detected. This permits even an object which is not precisely located at a predetermined position to be gripped accurately by the gripping device following detection of the object position.
