Abstract: The Reconfigurable Wheel-Track (RWT) is a novel mechanism that allows a wheel to transform into a track, and vice-versa. The wheel permits a vehicle to travel quickly over smooth and semi-rough terrain, then, on-the-fly, transform rapidly into a powered track for crossing extreme terrain. The reconfigurable wheel-track consists of several main components: an outer tire/tread, drive mechanisms for the wheel and track, support mechanisms for the outer tread when in either wheel mode or track mode, and a reconfiguration mechanism that facilitates the transformation from a wheel to a track and vice-versa. The reconfigurable wheel-track includes sensing, actuation, and controls to facilitate efficient and effective transition from wheel to track and vice-versa, and securely maintain each shape.

Abstract: The Reconfigurable Wheel-Track (RWT) device is a novel mechanism that allows a wheel to transform into a track, and vice versa. The wheel mode allows a vehicle to travel quickly over smooth and semi-rough terrain, then, on-the-fly, transform rapidly into a powered track mode for crossing extreme terrain. The reconfigurable wheeltrack device comprises several main components: an outer tire/tread, a drive mechanism for driving the tread when in track mode and a reconfiguration mechanism that facilitates the transformation from wheel mode to track mode and vice versa.
