Abstract: An expandable wheel has rollers arranged radially about a plate within a main housing. Spokes pivotally connected to the plate are attached to linkages on which the rollers are mounted. The rollers and linkages protrude through apertures in the main housing. The rollers form the circumference of the wheel. Rotation of the plate relative to the main housing changes the angle of the spokes relative to radii of the plate. When the spokes are parallel with the radii of the plate, the rollers are pushed radially outward at a maximum distance from the plate, forming the largest wheel circumference. When the spokes are as near perpendicular as possible with respect to the radii of the plate, the rollers are pulled radially inward at a minimum distance from the plate, forming the smallest wheel circumference.

Abstract: A mobile robotic floor-cleaning device with wheels that may be expanded or contracted to suit various needs by rotating an inner shaft within the main housing of each wheel relative to the main housing. A series of rollers form the circumference of the wheels, and are connected to the inner shaft via a set of spokes. Rotation of the inner shaft relative to the main housing causes the spokes to pull the rollers in or push them out, changing the diameter and circumference of the wheel.
