A.J. Vázquez, Madrid, Spain (EU)
Car body has a truncated spherical shape, 1.6 m diameter, divided in four 90º pieces. The top and bottom (dark grey) are metallic with a circular reinforced tube and fixed to the floor.

The four wheels are in rhombic position allowing an easy driving.
The driving axial wheels are those of a motorcycle rear wheel; the side wheels are the front ones. The two axial wheels are connected with a cross pulley. Turning right or left the former wheel, the back moves the same angle in opposite direction. This design saves weight, because don’t need differential nor transmission compensating in excess the battery weight, reducing price and maintenance costs.
