Below elbow amputees - prosthetic benchmark activities

I would like to invite the audience to contribute activities, grasps, tests that are relevant either for a particular job, hobby or for ADL (activities of daily living) and that should not be missing from a benchmark test of prosthetic setups.

The step by step instructions to create a lego hand are still under development. Here is a snapshot of where I'm currently at. I have modelled the sub-assemblies in LDraw, and uploaded the images to Flickr. (Can anyone recommend a photo site that will display the comments as part of the slideshow? Or know of an easy way to import 100+ images into a document?) Joining the sub-assemblies is still underway. I have not yet tested these instructions using actual legos. (I plan to order them soon.)… Continue

Calling all LEGO Hand enthusiasts!

Posted on January 5, 2010 at 3:00pm 0 Comments

The Open Prosthetics Project Ning site has 188 members, 129 of whom expressed interest in "helping with projects". I'm sure a significant number of you are interested in the LEGO Hand, as I am, but found it wasn't obvious how to contribute. I've decided to take a stab at getting a group of us talking and working together on the hand.



Here's where I suggest we start:

1. Share info to help each other build replicas of John Bergmann's original hand

2. Organize an effort to… Continue
