Description

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/

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.

Thank you

Help, help, I made printing and hand size is an adult.
I need this hand print in size to a child, like the photo:

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.
