M5Stack RoverC with mecanum wheels

Mecanum wheels are deeply strange. Each wheel contains rollers canted at 45 degrees so that when you drive them they apply a force at an angle to a normal wheel. In other words, if you drive something forward with a “normal” wheel you will get a force that pulls you forward. Drive something forward with a mecanum wheel and you get a force that will push you at an angle. By balancing the forces generated by each of four wheels you can drive forwards, backwards, sideways, around on the spot or at any other odd angle.

M5stack make a tiny robot with these wheels and it is great fun. I want to put one of their cameras onto it, so that I can get a robot that can see things and steer round them.
