Stefano's robotic gripper.

A gripper I have made as part of my college graduation project, based on the design of jjshortcut, included on his Robotic arm with 7 servos (see link on the left).

In my version, the mechanism is moved by a linear actuator (used to adjust automotive headlights) instead of by a servo motor. Also, unlike the original, I've used a robotic construction kit to prototype the main structure of the arm, so my gripper have two holes on each side that will only fit parts included in the kit. (see image on the left).

Lastly, if you do need to customize but don't know the first thing about how to create round toothed gears from scratch, you might also be interested in reading a document I wrote, compiling my experience on the subject so far: http://www.stefanomega.com.br/thingiverse/geartut/index.html
