Rack & Pinion Robotic Gripper Jaw

Servo Controlled Robotic Gripper using rack & pinion drive for parallel jaw movement https://youtu.be/Qfd0ikdnAsg This is a robotic gripper/jaw that uses a low cost Tower Pro MG996R servo. As opposed to some grippers that use a lever action, this directly drives both jaws with a rack and pinion action. It therefore has slightly more grip that traditional lever grippers and the jaw movement is totally parallel. It could be easily modified to fit on to a robotic arm. It requires: 1pcs Tower Pro MG 996R servo motor (approx price UK £5 / US $10) M3x15mm Screws (4 pcs) M3x10mm Screws (4 pcs) M3 nuts (8 pcs) To drive it, I used a servo motor test board and a USB phone charger (2.5A) But you can also use and arduino.

This was for a request to enable the jaw to operated a Rubik's cube of about 57mm Square. Please note that I haven't test this, so hopefully it'll print and function correctly.
