Pinchy
April 18, 2016 · View on GitHub
Pinchy is presented as the second iteration of our previous robot, uBot. It is an educational robot specifically made to be used as an ideal medium to start learning to program, know more about robotics and familiarize yourself with the basic electronic concepts.
What's this?
Pinchy is an open source educational robot that can be printed using ordinary 3D printers. It's made up of a PCB, used as a shield with an Arduino Micro on top of it, the before mentioned chasis and some sensors to interact.

Chasis
The chasis that makes this robot more than a custom PCB with an Arduino is made with our 3D printers helping us to reduce the costs of assembling a fully functional educational robot. All the necessary files are here.

Circuit and Board
Pinchy's main PCB
The circuitry that is needed is in the Circuits folder, there you can find the schematics and the CAD files for the main PCB and for the custom-made optoreflectors.
