    Abstract: A system for managing inventory items includes a portable inventory holder and an unmanned drive unit configured to move the inventory holder between locations in an inventory facility. The inventory facility includes a plurality of uniquely identifiable fiducial markers having a small set of values distributed in a pattern. The drive unit captures at least one image of a subset of the plurality of the fiducial markers. The at least one captured image is processed to determine a location of the drive unit within the facility. A path is determined along which the drive unit moves to an inventory holder and moves the inventory holder to another location. The pattern of fiducial markers can include one or more repeated instances of uniquely identifiable fiducial markers. A fiducial marker can encode information using a readable code and at least one attribute of the fiducial marker.

    Abstract: A system for managing inventory items includes a portable inventory holder and an unmanned drive unit configured to move the inventory holder between locations in an inventory facility. The inventory facility includes a plurality of light emitting elements. The drive unit captures an image of a subset of the light emitting elements. The captured image is processed to determine the location of the drive unit within the facility. A path is determined along which the drive unit moves to an inventory holder and moves the inventory holder to another location. The light emitting elements can be provided by optical fibers embedded in the floor of the inventory facility.

    Abstract: An inventory system includes an inventory holder that may be moved by a mobile drive unit. The inventory holder may hold inventory items. The mobile drive unit may move in a manner for facilitating a shift of position of at least one inventory item relative to the inventory holder. Such movement may be accomplished, for example, by accelerating, decelerating, turning while driving, spinning, dropping the inventory holder, or by causing at least one of the mobile drive unit or the inventory holder to at least one of interact with or engage an obstacle such as a bump over which the mobile drive unit drives, a bar positioned above a floor on which the mobile drive unit drives, a wall, another mobile drive unit, or another inventory holder.
