Abstract
A vehicle with unlimited mobility in all directions in the driving plane, in which the wheels are provided with a pivot drive which is set on the basis of values determined by a computer. The calculation is effected according to an algorithm, whose basis results from the geometric relations of triangles whose corner points are formed by the respective pivot axis of the wheel, the vehicle center M, and the center Dn, D'n of the instantaneous track curve.
