Much more impressive than the look or power of this beast (it handles dirt, grass, and other surfaces with ease... I'm waiting for the snow fan-tailing videos), is the fact that Steve has used it as a testbed for coupling GPS navigation with the NXT. Take a look at the videos (from 14 Sep) on Steve's webpage for some impressive (not to mention rather humorous) navigation attempts (PS, Steve's back yard is considerably steeper than it looks in the video). Currently Steve is using RobotC to drive the robot, which is completely autonomous, simply following a set of waypoint coordinates. He's also used pbLua to communicate with the GPS, and there are even some people who have managed this with the stadard firmware (although it's rather unclear right now exactly how that is done).
Now, anybody know where I can get a really small, simple, BT-equiped GPS unit? Serenity needs a captain... :-).
