Abstract

We describe an automatic initialization scheme for finding a point of coincidence betwcen a robot's internal coordinate system and the coordinate systcm of its work space. Our mcthod uses an optical transmitter-reccivcr pair mountcd on the robot end effector to scan a T-shaped planar target mounted on the work surface. An automated itcrative mcthod for moving a point on the end effector into precise coincidence with the point of intcrscction betwcen a sensed plane parallel to thc work surface and a sensed line normal to the work surface is shown to converge rapidly.
