Now for the electronics. I don't have a schematic yet but here is what the wiring looks like so far. I am using dual color LEDs for the headlights. Three color LED's would be better as they can do white as well as colors like red for stop.
I am using a L298 motor controller. To the left of the Arduino there is the power strip off a small breadboard to connect all of the power and grounds together. Not visible in the back there is a two line LCD and in the front there is an ultrasonic distance detector.
Here is the first video of it running.
Here is a second video with headlights and servo. Next to get a Nerf launcher on there.
