ABSTRACT:
A method of controlling a transport means (1) comprising a body (2) and wheels (3a to 3h) attached to the body (2) on both sides of its central line one after another in the longitudinal direction of the body, all the wheels (3a to 3h) being arranged to turn about vertical axes (4a to 4h) of turning to change the direction of travel of the transport means (1) so that rotation axes (11a to 11h) for all the wheels (3a to 3h) intersect substantially at the same vertical axis of turning (9) so that the position of the axis of turning in the longitudinal direction of the transport means (1) is shifted in proportion to the magnitude of the an angle of turning (.alpha.); and a transport means (1). To avoid an unexpected obstacle (10) the turning of the wheels (3a to 3h) is deviated from their normal path by shifting the axis of turning (9) in the longitudinal direction of the transport means (1) towards its forward end, so that the rear end moves with a larger curved movement than usually. When the driving conditions are normalized, the axis (9) of turning is returned to its normal position.
