How are you? First of all, great work with the platform and thanks for welcoming me to the community! I'm guessing you've seen by now but I'm looking at developing upper body prosthesis that enable interaction with others, shaking hands, holding hands, dancing, feeling a childs temperature, feeling someone touch a prosthesis and sharing emotions. It would be super helpful if you are able to spend 2mins answering my survey!
Thanks in advance! If you're interested to know more and have time for correspondence it would be great for my project. It would be great if you could spread it to friends and family who wouldn't mind answering the survey too, through their perspective of how they'd like to interact with a prosthetic hand if it could feel.
Thanks John, we are always happy to share information that will help animals. We are writing up the official story of the crow and the goose right now to gather all the facts. We can share the articles once we get them written up.
I am a new fan of yours from India. I have read your articles and blogs about amputation. We were a bunch of students who were doing a prosthetic arm project, just for fun. But then we have came across the real trauma of amputation during the pre project survey(read the full story on our blog shabdorg.blogspot.com). After that incidence we taken this project as our life long project. Our mission is atleast we could give our national amputees at least what people of your country can get. In our country each year million of rupee is wasted on research and the final product is kept in the research center itself as a showpiece. The reality is in our country 80%amputees never get more than the bandages over the wound. Anyways we are not in favour the new research of transplantation of arm from a brain dead person to an amputee. Though its almost 100% successful (49/50), it is death of ethics and almost killing someone for a rich man amputation surgery.
In the meanwhile we came across your website and at last we are here. We just want to enquire how really this site helps us to achieve our goal. Please do contact us, my mail id is firstname.lastname@example.org
Some people found it useful that the Carnes arm's feature used position dependent motion combination. There was elbow dependent wrist rotation allowing pronation for an extended elbow and supination for a flexed elbow. So from past experience some position dependency of prosthetic function could be justified to be 'useful'.
With limited input variables, the one and only clever way to exploit these constraints has not been found.
So my guess would be to include the Bosch accelerometer, build a demo and start testing it. Only when you wear it and play with it you can find out how cool or how useless it really is.
Just starting out, Jon, and your link to Open... was very interesting. Just FYI, I have an evaluation board for the Micro line of Microcontrollers. It has a Wii-like accelerometer and some demo software that makes it like a Wii. The accelerometer proper is a digital wonder chip from Bosh, costs ~$5 small quantities. So, if Wii-like motion sensing is wanted, it looks like it is in the bag, more or less, already.
I'm including the simplest schematics ckt. that i ever designed for this prosthesis hand. Please note, i tried to use only those components which are only available in developing countries (like my countriy Bangladesh). Moreover it minimize the cost dramatically with a small sacrifice of performance.
OLÁ JON! RECENTEMENTE ANALISEI ALGUNS ARTIGOS DO SITE IEEE,E
NUM DELES VINHA FALANDO SOBRE SEU CASO.SOU ESTUDANTE DE ENGENHARIA ELÉTRICA E ESTOU INTERESSADA EM DESENVOLVER PESQUISAS NESSE RAMO DE "PRÓTESES".O QUE DIFICULTA É QUE NO BRASIL AINDA NÃO ENCONTREI EM MINHAS PESQUISAS INSTITUIÇÕES VINCULADAS À ESTUDOS TAMBÉM DESSE RAMO.
GOSTARIA DE ENTRAR EM CONTATO COM VOCÊ E SE POSSÍVEL OBTER INFORMAÇÕES QUE IRÃO CONTRIBUIR PARA MEUS ESTUDOS.
Mr. Kuniholm, I've just joined this site due to the Scientific American article. I've been a bilateral knee disarticulation amputee since I was 8, and I've gone through a good number of prosthetists who knew little on how to handle sockets for the type of amputation I have. In part, thanks to this, i've learned about socket designs, artificial knees and feet.
While I'm studying Aerospace Engineering, I've had a few ideas on socket more generalized socket designs for lower extremity amputees. Basically a flexible and open socket, lined with high density foam, with straps to hold close the socket on the stump. The idea that I had with this, is to produce a very generic socket that could be mass produced for use in third world nations where amputations are not uncommon (due to war, landmines, etc.).
I'm more than willing to help out in any way possible for this initiative.
Mr Kuniholm Hi my name is Joan and I live in Panama and last year I had an accident with an industrial machine where I amputated finger and little finger cancel it AMPUTATION partial hand. I am interested to know what kind of financial help you could through his organization helps amputees could donarme a partial hand prosthesis based on silicone either aesthetics or function as it does not have the resources and in my country neither helps people like me.
Yup, I made the scrubber. I have made a few attachments since I lost my arm in Iraq 11 months ago. There is definitely a lack of interest in the body powered arm prosthtics. Hopefully we can make some cool stuff on here.
I have been able to take a look at the knives made by Texas Assistive Devices, and they look like they would be pretty solid to cut with. My main focus is to try to make a device in which someone could walk into any kitchen, choose any size blade/handle knife, and then be able to use it without slipping.
I've been looking at technologies used in making guitar capos to try to create a robust grip. I found a new patent (2003) that involves a spring loaded hinge that locks at any angle as the hinge is being closed and then expands to its original shape when a lever is pressed to unwind the spring. So far, it looks like the best way of delivering a strong grip with little amount of preparatiion. I'll definitely let everyone know how it turns out!
Good to hear from you!
