Abstract
In a control system for a robotic gripper a processing circuit (10) controls movement of the gripper (20) on a prearranged path. An article (A) held by gripper (20) comes into contact with the probe member (32) of a 'known-down' sensor (30). A support assembly (33), on which the probe member (32) is mounted, is displaced with respect to a base member (31) allowing a continuous, uninhibited movement of the gripper along the path, even after contact has been established. In an alternative arrangement the sensor is mounted on the gripper and establishes contact with an article located at a fixed work station.
