When I followed the documentation I had a little trouble with the
different views and that some of the parts did not have a quantity
label. I can review the directions again and mark possible changes
then email it to Jon. I took a look at the LEGO CAD program and I
remember someone saying it did not have all the parts that were used

I'd certainly appreciate your making sure that you fill in any gaps in
the documentation that you find. Remaining work includes figuring out
how to actuate the hand using NXT. If you're ambitious, documenting
the hand using a LEGO CAD model, including modeling the pieces used
that aren't in the standard LEGO CAD packages would be awesome.

I began summer research today. I have constructed the hand using the
documentation online. I am now researching and waiting for my advising
professor to come back in town to see what our next step will be. I
will do my best to update my progress weekly.

I'm very much in accord with Simon's comments about the ridiculous
repair costs, but more I'm concerned about the interlocking medical/
prosthetic industry, which treats us as diseased "patients" and our
prosthetics as integral body parts. Granted, it takes expertise to
make a well-fitting socket, but at the other extreme, I sit in a

Daniel & Co.:
Please visit the Wiki page ([link])
for a list of all of the current projects that are being actively
pursued to get assistance in solving problems. One that intrigues me
is the updating of the APRL hook, which is an incredibly sophisticated
design that needs sturdier parts than the cast aluminum case, etc.

My company is wanting to get involved somehow. I have 12 techs (some
software oriented, some hardware oriented, some both), 4 fabricators,
and 4 people with experience in all three areas (electronic -
software, electronic - hardware, and fabrication/rapid prototyping)
and we have two techs who are also NREMT-P and one of my managers is a

Hand model

If you are interestedin the some of the prosthetics we are working on there are a few people you can talk to. I made a prototype lego hand that is unpowered, but has most of the movement of a real hand. That is just one example though. The website has more stuff on it.

I am an engineering student at Sweet Briar College. My advising
research professor, and I were looking into doing prosthetics research
this summer. Our interest is in prosthetic hands, hints the interest
in this project. Is there a specific group or person we could contact
for more details about it or is everything basically online?

Might I point out the Sanguino. Slightly smaller and cheaper than the
Arduino but yet compatible with it and with 4x the memory:

wasn't able to figure out everything he was saying, so I left some

In the electric impedance tomography; really you're just detecting the
difference in voltage around the arm. You can use pennies for
electrodes.

According to this you can use lotion to make the electrodes have
clearer readings. I know this article is about the EKG, but it really

Wristband sensor

2008-12-29T09:59:08Z

I'm exploring the initial stages of an idea for a new input device.
Essentially, the device would be a wristband containing sensors of
some description, where the sensors pick up movements in the wrist
corresponding to finger movement (basically creating a chording
keyboard where the user only has to wear a wristband). While my

Has anyone contacted Dean Kamen on his new arm he is developing for
the brave men and women who lost arms in war?

Hay:

I think you might be a little late because that is exactly how the
iLimb works. I got to see how it works at a show (AOPA it think?)
last March.

Although now that you mention it a three finger version might be more
functional than the iLimb's five fingered hand.
