There was an artricle about Robo Magellan in one of the free Servo magazines we got this year (Or maybe last year) It was about some one who won a competition he used a remote controlled truck kit (Traxxas makes some great ones) as a base then added Ultra sonic sensors for obstical recognition and avoidance as well a digital compass to stay on track. Finally he used a CMU cam to Identify the traffic cone that marked the end point. I dont remember what he used for a controller but all of those sensors could be used with the Vex kit EDU controller or for a little more power a gumstix, any thing with a serial port could be used.
