This is a design for progressive movement fingers that use small linkage devices inside each finger. These linkage may need to be printed in metal or made in metal in order to hold up to real usage. This design also takes advantage of a lateral pivot at the top of the wrist joint. This enables progressive and independent gripping of each finger. This object is still in testing phase so beware.

See http://www.thingiverse.com/thing:221560 for updated finger with larger range of movement.

This design was created by Bob Roth from Tulsa, OK. and he has been gracious enough to share the design with our community of makers.

This project is an extension of the work being done by Robohand, Ivan Owen, Jorge Zuniga, and the e-NABLE group. This work is being done in my lab at the University of Wisconsin Milwaukee.

I wish I could make something like that

Hi! Has anyone ever completed one of those hands? I would love to see one, as I don't really understand the connection from the fingers push/pull rods to the wrist movement.

Is there a possibility to get an iges file oft this awsome design?

Thanx in advance:::ben:::

Please thank Bob Roth (https://plus.google.com/u/0/106162796811521778880/posts)https://plus.google.com/u/0/10... as he was generous enough to share it with me. I just translated the files. Bob used steel cables I believe when he made this. There are not motors involved. It is all based on the movement of the wrist.

Thanks for making this design available. This kind of work is why I wanted to get into 3D printing. Cheers.

how do you controll the fingers, with strings attached to a motor?
