This is a video of a project I made for fun, an NXT Sandcrawler. It's basically the base from the nxt clone tank with a "sandcrawler" body.
It's controlled by a touch sensor. to control it, all you do is hold the button for as long as you want it to go forward. Then, you press it and it goes left. the third time it goes backwards, and the fourth time, right. Then, it starts all over again! I believe the originator, or at any rate who I got the idea from, is Dave Parker. you can visit his site on Nxtprograms.com. It is, in my opinion, one of the best NXT websites with free building instructions out there. It also has insructions for both versoins of the nxt. It is a great site and I highly recomend it.
