Hello all!

Another update on the finger prosthesis project. Richard, the co-creator and designer of what we've been calling "Robohand", now has a more refined version of the prosthetic which has a new tip that allows him to perform precise tasks like....

One of the best aspects of this current design is that much of it was constructed from things one can find at a hardware store. The main lever arm & mounting arm for the tip were made from a brass door hinge. The control ring was made from a plumbing fitting. The grip-pad on the finger tip was made from a pad that you can buy to stick underneath table legs. The sleeve to provide padding for his stump is a finger-grip that office workers use when sifting through stacks of paper.


Here are a few images of the latest device:


The only specialty components involved in this design are the orthopedic plastic used to create the hand-mount (usually obtained via a doctor or physical therapist) and the tiny ball-joints (the little ball joints are used in RC cars and can be obtained via a hobby shop or online store).




Within the next week, for those who are interested, we'll be sharing more detailed information on how the prosthetic devices are constructed on our blog: http://comingupshorthanded.com/2013/01/04/celebrating-our-first-year/

I still think this is the awesomest thing anybody has ever done.  If I had money, I'd send it to you.

I love that you got most of the stuff from a common hardware store and yet it has a certain elegance as well as being functional.  The polished brass is particularly lovely.
