[Frank Herrmann] had an interesting idea to turn a geared DC motor into ... the ‘stepper motor driver’ interface pins hooked up to the motion controller upstream. The Arduino source for ...

The robot itself is relatively simple, with four geared DC motors, motor drivers wired to an Arduino Nano that interfaces ... you can train a custom autonomous driving policy to suit your environment.

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...
