A locomotion assembly (20) is provided, suitable to be used in a vehicle. The locomotion assembly (20) comprises a frustum-conical structure (30) comprising at least one flexible member (34) having a frustum-conical surface extending between its relatively narrow (38) and wide (36) ends along a frustum-conical axis (A), the frustum-conical member (34) being reversibly deformable from its biased rounded shape corresponding to a frustum-conical shape in which its side elevation is circular into a deformed frustum-conical shape in which its side elevation is non-circular. The frustum-conical structure (30) may serve for supporting at least one surface-engaging member (22) convertible between a round wheel-like configuration, in which its side elevation is substantially circular, and a deformed configuration, in which its side elevation is non-circular and in which a larger portion (70) of the surface-engaging member (22) is in contact with a movement surface (72). |
