Abstract
A robotic gripper (10) has fingers (12) that are configured to grasp an object, and an actuator (20) for driving the fingers. The actuator has a drive train (30) connected to the fingers for driving the fingers, an impact mechanism (40) mechanically connected to the drive train for driving the drive train, and a motor (50) connected to the impact mechanism for driving the impact mechanism. The impact mechanism generates a series of impacts that are delivered to the drive train when the impact mechanism is loaded beyond a threshold torque. The drive train is a back-drive inhibited drive train provided by a worm drive (32, 34) that is mechanically coupled to the impact mechanism.
