Bicep for Robot InMoov

Here is "InMoov", the robot you can print and animate. You have a 3D printer, some building skills, This project is for you!!
Don't be scared or intimidated, I started this a few months ago and didn't even know what was Arduino or a servo motor!
Start with printing the hand like I did, and go on the rest if you feel.
