This is a single axle with a hub that mounts to our 6 inch tires. The end opposite the hub is bored to fit an 6mm shaft. It is intended to be direct driven by our IG32 motors. The hub is welded to a steel 1/2" diameter shaft.
This is a programmable autonomous robot prebuilt kit that can be controlled via Gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. BeagleBone Black (Rev C) microcontroller provides the most flexible platform possible.
