Unity/Arduino controlled robot base

This is not a game, so please forgive me if it should not be in the Showcase section.

This is an electric wheelchair that I replaced the electronics with a laptop, arduino and a couple of motor controllers. It is a Unity controlled base that I will use for various robot projects in the future but for now was just an opportunity to learn serial communication and how to control large motors.

See it in action here:

(please note, some bleeped cursing in the beginning of video from a clip of me exploding one of the chips )
