Design files for our proof of concept, open source, 3D printed robotic hands, controller, and user interface Android application.

This project is for DIYers, STEM students/enthusiasts, and developers who enjoy 3D printing, developing microcontroller firmware, and soldering electronics. The project is designed to use mostly standard, off-the-shelf, low-cost components available from online retailers.
