Dyson Ball?

Before i start designing the vehicle itself, as in the chassis, i was thinking on wheels to start with, how would the vehicle move? So i decided to design a different type of vehicle, much like the "Hailfire" from Starwars.

Once i did a quick mock-up of wheels of the vehicle, i started to think how it would move, and how the chassis stay upright, without spinning with the wheels. I found this picture which helped me visualise a bit more to how the wheels would move around without the whole thing spinning; 

 

I liked the look of this and i see how the wheels would move around the whole circle effectivly. But if i don't want to model a vehicle like the Hailfire, i wanted more of a genuine care look to the vehicle, with a different type of movement. And while i was sketching this car;

And while i was sketching the ball wheel, I looked into how the Dyson ball technology works, which if i could get a ball to work as a wheel it would move alot differently than a normal wheel.

The picture above just shows the one wheel, and how it move compaired to 4.
