Abstract: Concepts of omnidirectional vehicle transport are described. In one embodiment, an omnidirectional vehicle includes a transportation platform, a drive system, and wheels. At a surface level, the vehicle can maneuver in any direction, including longitudinal and lateral directions. The vehicle can also be positioned to engage the wheels with a track having a rack gear to engage with the wheels. A control system of the vehicle can then drive the wheels in engagement with the track to raise the vehicle to a second level. At the second level, the vehicle can maneuver to transfer items onto the vehicle for transportation of the items back to the surface level. After the items are transferred onto the vehicle, it can be positioned for engagement with the track, and the control system can drive the wheels to lower the vehicle to the surface level and offload the items.

Abstract: Concepts of an omnidirectional pinion wheel are described. In one embodiment, the wheel includes a hub, first and second annular rims each including inner and outer rim surfaces, spokes that extend from the hub to the first and second annular rims, a pinion ring including pinion rods that extend between the inner surfaces of the first and second annular rims, and first and second annular rings of rollers affixed on the outer surfaces of the first and second annular rims. Using an axis of freedom of the rollers, the wheel can move sideways in addition to forward and backward. Further, when used with a vertical rack gear, the wheel can provide vertical displacement by engagement between teeth of the gear and the pinion ring. Additionally, various racks and tracks with teeth for pinion ring engagement are described along with an example vehicle capable of vertical displacement using the wheels.
