New experimental gripper for Robobuilder

Thanks very much.

Its hard to gauge - but the model is very tough - I suppose it depends on how far it falls, but a simple trip won't have much effect. The tendon is the weakest link. I still need to do some experiments to characterize its behavior under load.

beautiful work!
how hard is the material? can the robot fall on the hand safely?

A few details:

It consists of two pieces, the first is the fingers and thumb with flexible joints and integral tendons. A second piece attaches to the wck central shaft and acts as a cam pulling on the tendon. It's designed to use the existing nuts and bolts that come with the kit. Two B40x66 bolts with nuts hold the fingers in place and B12 through the cam attaches it to the wck servo with a nut.

More photos are /will be available at http://www.shapeways.com/shops/ip_robotics as well as other gripper design.

I'm attaching pictures of a new gripper, built by 3D printing for Robobuilder.

Will post some video of it in action soon.
