In this video, I build the smallest possible RC Lego car, using only Power Functions components. To count as a remote control car, I decided that the vehicle had to be able to drive and turn independently. I started by building a simple but compact car. I then tested it by measuring the horizontal and vertical gaps it could fit through, and its turning radius. I tested its maneuverability by driving it around obstacles.
I then tried building narrower cars, with the compromise that they were longer. I took this idea to its limit, where the car was as narrow as possible while still housing the Power Functions components, but it was impractically long.
Finally, I built a car (more of a tank) that could both drive and turn with only one motor, reducing the size further, and tested it against the same obstacles.
