Hey guys, sorry for not posting for a while, but on my countless hours of searching the web, i found this: NXT Explorer, it's a robot, that has 6 treads on it, all of which move! This requires countless hours of thinking, and countless hours of building to make, think of all the gears that go into this!
I made one of these once. It wasn't quite as reliable as this one, but it worked pretty well. It took about 9 hours to build. The main challenge was the sheer torque required, something difficult to handle with LEGO gears. (ABS does have it's limitations...) But it was a really cool vehicle to have built.
