This thing is a basic model of a mini RC sumo car project using the common N20 gear motors and a HotRC wireless remote controller. It includes a large pocket for a dual-18650 battery holder, a recess in the bottom for an 8833 dual motor driver, and a clip for holding an Arduino Nano. Rubber for wheels is meant to be a 1/2" slice of 1" silicon heater hose.

It is basic in the sense that it "works" but it is not a good sumo car because it is not ballasted correctly and it has no blade. The idea is that students take this design and make something better out of it.
