Abstract: The present invention relates to an omnidirectional wheel including a central hub; and a tread peripherally mounted on the central hub. The tread includes the juxtaposition of wheels or sleeves arranged along radial planes. The wheel also includes spokes connected, two-by-two, via a shaft section. The shaft section is coaxial to the hub, which has a round cross-section, and onto which freely rotatable rings are fitted. The shaft section includes struts inserted between each ring and shaped such that rings remain in a radial position. The shaft section also includes a series of a plurality of abutting tubular segments. The invention further relates to a module for assembling an omnidirectional wheel.

Abstract: The device for crossing obstacles for a motorized vehicle includes a chassis connected to n (n?3) wheels on each side, and a driver suitable for rotating the wheels. Each side of the chassis includes a mechanism comprising n?1 arms hingedly connected two-by-two about a shared pivoting axis on which the n wheels are distributed, respectively a front wheel, n?2 intermediate wheels, and a rear wheel. The mechanism allows each wheel to pivot relative to the axis of each adjacent wheel.
