Abstract
The present invention provides a rotary gripper for robotic use including a support portion for connection to a robotic apparatus, a gripper head movably mounted on the support portion and carrying a pair of opposed gripping fingers, a first drive mechanism for opening and dosing the gripper fingers and a second drive mechanism for rotating the gripper head. The drive mechanisms are generally transverse relative to each other and each includes at least one pneumatically driven, reciprocating piston. In the first drive mechanism, a pinion gear is operably connected to the piston for reciprocating movement therewith. The piston in the second drive mechanism is operably coupled to a rack engaging the pinion gear to turn the gear, thereby moving the gripper head relative to the support portion.
