<p>A manipulator comprises a carriage on which is mounted a peel having jaws for gripping a workpiece. The peel can move relative to the carriage longitudinally vertically and in tilt. Detectors give signals representing parameters on which the position of the peel depend and a circuit derives from those signals an indication of the position of the jaws, taking into account the angular attitude of the peel. The position indication can be used to control the peel jaws to a required position relative to the carriage.</p> |
