Let's get to some of the details of how I built this. The motor, gears, etc., were just parts from my garage salvaged from all manner of electro-mechnical devices over the years. The Arduino, motor shield, battery pack, and various minor parts were all purchased off of E-Bay. In this example they are in two groups in parallel of two batteries in series that power the headlights. It has room for two battery packs - a 12v 1800mAh that drives both the Arduino board and the motor via the motor control shield and a series of four 3.6v 280mAh surplus cell phone batteries I found on-line that can be arranged to run in series or in parallel as your power requirements demand. I designed it with the idea it would be a flexible platform to experiment with and to be able to add accessories, like the blue LED headlights, which is what the small green breadboards are for. My first robot! I built this from the ground up, designing the platform, drive system, sensor array, and programming.
