That's some great engineering work!

This is brilliant!

Think of realistic uses for this.

I figure land/ice surveys in the Arctic and Antarctic.

Wonderful work of imagination! Now, couldn't this concept be somehow scaled up into a human-carrying vehicle, such as a personal flying car for everyday use? It would certainly reduce the need for so many highways and roads.

Why a robot? A ballast tail should suffice. Make ballast the battery. That would obstruct the roll cage, but would prove the computer redundant and a useless weight.

I doubt this unit has a price below the $100 needed for off-the-shelf radio control parts.
