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

This is Esteban Alvarez 3D Mechanical Design coordinator for the Open Prothetics Project, today I have finished the assembly, as you can see of the attached pictures.
Eventually I'll upload the files for sharing with every member, today I will upload IGES format. If you need a particular 3D format please don't hesitate to ask me to the next email: email@example.com…

Regarding Paul Hochman's recent Fast Company article on prosthetics
, as both a consumer of prosthetic arms and an engineer working on the most ambitious prosthetic arm project in history, I have some significant problems with his portrayal of the clinical state of the art. The basic premise raised in the article, that we're anywhere close to "Super Human Prostheses You'll Envy" is laughable to… Continue

Hi Jon, Thank you for inviting me and letting me know about this site and I'm looking forward to helping others.
Let me introduce myself, I am a fifty three year old dominant right above elbow, extremely short amputee. Six years ago when I lost my arm I feared the worst and it has been hard. Murphy’s Law dictates these things will happen at the worst possible time. My business nearly went broke, the small town syndrome, and the vultures were circling. I checked out of hospital and went… Continue

When we incorporated, we imagined that our ideas for open design mattered to many more markets than just amputees, which is why we're the Shared Design Alliance. As one way of tackling problems like ours, I've proposed an open source TV design show for a new Changemakers
Called The 90 Per Cent Solution
, the show would use the power of the crowd to… Continue

I’m not sure if you are aware of some of my latest projects. One of them is to mould the left arm and hand of interested amputees. Any prosthetist or art and sculpture student can do this with strips of moulding plaster on your left arm, upper and lower with elbow bent at ninety degrees without hand at this stage. This female mould in two halves is taken off the arm, put back together temporarily and casting plaster… Continue

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

has written a great post
on some of the issues surrounding open hardware and the differences between hardware and software. As one of the comments below notes, the possibility of well-documenting prior art is absent from the analysis, and is another avenue for preventing patenting of design ideas.
I think… Continue

While I've complained about the fact that many of us are using hooks strongly resembling that designed by and still bearing the name of David Dorrance, who patented the split hook in 1912
and whose company survives today
, there are many benefits to the design. There's a reason that some designs are… Continue

A tip from Brad Veatch of ADA, the developer of the LESA prehensor
(not yet available).
A little teflon pipe thread tape underneath the rubber bands on the hook when you replace them will reportedly increase the life by eight times. Brad apparently has data to support this with cycle testing, and I hope we see that in print soon. My experience has… Continue

I've spoken before about the need for a standard for prosthetic/robotic arm (or leg) control, preferably one also adopted by a larger industry. University of New Brunswick Fredericton (UNB)'s AIF UNB Hand Project
has settled on a CAN-based communications system, using the established standard for automotive communication. Under the name of a consortium that has long sought to standardize upper extremity prosthetic control,… Continue

Seems very cool how the design space is at least moving forward through software, now all we need is to make these babies readily available.... soon very soon!!!

I saw something tonight on a prosthetic supply website that really got under my skin so I decided to write this up.
I quit using the standard rubber bands on my hook about a year ago. Because of the nerve damage to my remaining hand they are nearly impossible for me to put on by myself. While in my local farm supply store one day I happened to stumble upon some small green rubber bands used for animal castration, and some special pliers to put them on with (I think Sean was the one… Continue

Phase 3: Design Phase
In phase 3 I modeled my ideas in SolidWorks analyzed my ideas in Microsoft Excel and then used my final model to make a rapid prototype. Here are the results of my many hours and late nights:
Here are some of the features my design includes:
1. Wide opening in between fingers for increased visibility.
2. Curved grasping… Continue
