Abstract
A robot 'touches off' on the orthagonal touchblock faces of a workpiece holding fixture and the coordinate of the touches along axes nominally normal to the faces provide significant data from which a coordinate transformation indicative of the orientation and location of the touchblocks in the robot frame of reference can be determined. The coordinate transformation is subsequently applied to workpiece coordinates indicative of the location and orientation of the workpiece and/or points thereon.
