A robot gripper is disclosed which, instead of the usual gripper fingers, carries two expandable gripper mandrels. These mandrels mate with two sockets on a powered screwdriver adapter and may be expanded to grip the sockets when it is desired to move the screwdriver to a different location. Air and vacuum are supplied via the mandrels to provide screwdriver bit changing and screw pick-up during use. Fig. 1 shows a controllable robot gripper 1 carrying two expandable gripper mandrels 2 which may be moved towards or away from each other. A triangular adapter housing 3 has two sockets 4 at two corners into which the gripper mandrels 2, appropriately spaced, are inserted. The third corner of adapter housing 3 is bored to fit the drive output end of powered screwdriver 5.
