A resilient wheel structure having a rim and a hub interconnected by spokes, wherein the rim is sufficiently stiff to distribute a load to all of the spokes, and wherein the wheel is able to absorb loads in both the radial and axial directions. The rim comprises an inner and outer rim portion supported by ribs, that are located co-radially with curved spokes that allow tension and compression. The wheel structure being optimally used on a mobile robot.
