A vehicle (2) for moving along a bifurcated channel comprises a guiding unit (4) having a propelled body unit (6) and a directional controller (10) attached to front (8) of the body unit (6). The directional controller (10) is displaceable relative to the body unit (6) between a first and a second position eg by rotating. Upon engagement of the directional controller (10) in one of its positions with a wall of the channel the guiding unit (4) is physically guided along one track of the bifurcation. The vehicle (2) can comprise carrying wheels (12), and the guiding unit (4) can comprise other guiding elements, such as guiding wheels (56 for laterally stabilisation. |
