Three Finger Gripper

This is the first version of the gripper for my robot arm project.

I used 3mm carbon fiber rods as shaft. They are cheap easy to cut, strong and light.

The motors are 16mm DC geared motors with 180 rmp anything from 100-200 should work fine. They are also quite cheap.

To improve the grip I used some rubber foam (in german Mosgummi).
