    Abstract: A gripper and wrist joint assembly for a robotic arm. The gripper comprises a pair of identical jams connected by a pivot and including V-sections for holding large objects and end-mounted pivotal tips for holding small and flat sided objects. The jaws are opened and closed by rotation of a screw-threaded rod having screw threaded connections with the jaws, the axis of the rod being fixed and the pivot pins being guided with linear displacement during adjustment of jaws so that they are maintained central within the gripper housing. The wrist includes a pair of spiroid level gears driven by respective spiroid pinions and each meshing with an output bevel gear carried on a shaft equipped with an adjustment nut for engaging the bevel gears into firm engagement and enabling backlash to be eliminated.
