Nothing in this video rotated so much as just one degree, minute, or second of arc, not even the transporting trailers/vehicles. The skid pipes are a good idea, and maybe some bogie casters at the corners would help. Sic Dean Kamen on it, but it will be tricky to control the engine closely enough (time constant is too long.)

Great fantasy, though.

See http://www.me.berkeley.edu/one_wheel_vehicle/Movie.htm for a video of Taylor's machine.

Your video was definitely better than the other one. It's hard to tell for sure, but it looked as though the frame bottomed out on the road a few times. It was a pretty flat road, though. I don't see this as working where there are rocks, roots, potholes, or quick changes in grade. Despite all that, the idea is indeed intriguing, even though this vehicle is just plain too large for trail navigation. Excellent exercise in feedback control, though.

Are these guys serious? look at the acronym for the society's name!

the acronym seems fitting because it looks like that's whats going to be dragging on the ground in this thing!
