Servo Controlled Robotic Gripper using rack & pinion drive for parallel jaw movement
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.
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.
You may need to file or remove excess plastic inside where the nuts go
