When you want to make a mobile robot, DC motors can be a great choice. We normally accept that they can be purchased for a few dollars each, but what if you want to make your own?
In order to assist with the winding process for a self-built—or at least self-wound—motor, Mr. Innovative created an… innovative fixture with two stepper motors and an Arduino Nano for control.
Arduino code and electrical drawings can be found here, and 3D-printed parts are available on Thingiverse.
