What's further interesting about using hemispheres as wheels is that you can maintain constant driving power to them. You can drive all four "wheels" with a single gearbox. You do not even need to vary the power output to vary its speed.
This, to me, is far more interesting the square wheels. Who wants to file for a patent?
