Abstract (en)
[origin: WO0128796A1] With a vehicle comprising a motor (5; 12; 20, 21; 32, 33) and at least one rotatable element (1, 2; 15; 18, 19; 30, 31) which follows the ground, for the purpose of propelling the vehicle, the motor (5; 12; 20, 21; 32, 33) is adapted for influencing the momentary position of the centre of gravity of the vehicle relative to the ground in such a manner that the rotatable element (1, 2; 15; 18, 19; 30, 31) performs a rotation under the influence of gravitational force. The vehicle is compact and has a simple driving mechanism.
