Robotic gripper

A robotic gripper. Each of two gripper fingers is attached to a bearing carriage. Each bearing carriage defines a rack gear and is adapted to ride on a bearing rail. A single pinion gear has two gear elements. Each of the two gear elements are meshed with one of the two rack gears so as to drive the two bearing carriages in opposite direction upon rotation of the pinion gear. A worm gear is fixed to the single pinion gear. A worm screw is meshed to the worm gear and adapted to cause rotation of the worm gear and the single pinion gear and a gripping action or a releasing action of the two gripping fingers, depending on the rotation of the worm screw. A motor is adapted to drive the worm screw in a first rotary direction and a second rotary direction.
