PlyBot Plywood Robot
The PlyBot is a 5" x 7" differentially steered robot made from 1/4" aircraft grade plywood. It is shaped from a rectangular piece of plywood, and requires only minimal cutting and drilling.
It is powered by two Tamiya gear motors (made from kits) and two Tamiya 58mm diameter rubber wheels. A steel ball transer (aka ball caster) is used for balance on the end opposite the motors/wheels.
