Description

3D Printed 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.

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.

Looking really good. I would like to use your design for a different sized servo. Do you have some CAD-Files (.step would be great) for me to adapt the size?

Hi, thanks for excellent design. What is max/min distance between jaws?

Good design, Provides the best amount of force because there are not components to flex between the motor and the jaws.

Hi, would it be possible to email me the part files because they are saving to my computer as if they had been sliced. my email is maria.peralta@du.edu. thank you so much and if that's not possible that is also ok.

Hello and thank you for your interest. I do not use SolidWorks and this was done on Fusion360. I can upload the Fusion files if you like.

Hi, It seems Pinshape won't allow fusion files to be uploaded. I also have this design on thingiverse so have put it there. https://www.thingiverse.com/thing:2661755/files
