Servo-Controlled Robotic Gripper Using Rack & Pinion Drive for Parallel Jaw Movement https://youtu.be/Qfd0ikdnAsg This robotic gripper/jaw utilizes a low-cost Tower Pro MG996R servo to achieve smooth, parallel jaw movement. Unlike traditional grippers that rely on lever action, this design directly drives both jaws with a rack and pinion system. As a result, it offers slightly more grip and precise control over the jaw movement. The robotic gripper can be easily integrated into a robotic arm setup, making it a versatile addition to any robotics project. Key components required for assembly include: 1 Tower Pro MG996R servo motor (approximate price: UK £5 / US $10) 4 M3x15mm screws 4 M3x10mm screws 8 M3 nuts To power the robotic gripper, a servo motor test board and a 2.5A USB phone charger can be used. Alternatively, an Arduino board can also be employed for control.

However, it closes to only about 22mm. This modification was made in response to a request for the gripper to operate a Rubik's cube measuring 57mm square. Note that this new design has not been thoroughly tested and is intended as an experimental variant.
