Amazing project. I have enjoyed a lot making this design.
It is incredible how with 3d home printing technology we can print things that are so useful :-)
Thank you UCFArmory and http://enablingthefuture.org/

I am the president of the e-NABLE program at Siena College and I am trying to build this arm for a recipient in need. I am having trouble with the electronics. I have had experience in circuits but I seem to be running into a lot of issues. Firstly, I was wondering if you used an arduino micro because it seems that the code is too big for the micro. In addition i was wondeirng if you have a schematic or a picture of your circuit that you can send me. You can email me back at firstname.lastname@example.org if preferred. I would really really appreciate it if you could help me out with this. Besides me, it will greatly help the girl I am working with who is really looking forward to this arm.
What sized printer would I need to make this arm for an adult?
please guide me regarding the sensor used. please post a link from where you bought it.
Help, help, I made printing and hand size is an adult.
I need this hand print in size to a child, like the photo:
How do I print the hand of the hand size of a child?
Awesome job! Did you use NinjaFlex, or some other flexible filament for the cartilages?
Hi friends from UCFArmory,
I tried with ninjaflex and it worked, it goes like a charm,
the most difficult has been to fix the tendons to the servo, it has been a little bit tricky but the final result is amazing.
The emg sensor I have used is the grove emg detector (http://www.seeedstudio.com/depot/Grove-EMG-Detector-p-1737.html)
the strategy I have implemented has been to see the variations between current and previous emg sensor input to determine if the arm has moved.
