Abstract:
To substantially reduce or eliminate disadvantages and problems associated with inventory systems, and more specifically, provide a mobile inventory system that supports techniques for automatic correction of particular types of operational errors.SOLUTION: A system for transporting inventory items includes an inventory holder capable of storing inventory items, and a mobile drive unit. The mobile drive unit is capable of moving to a first point with the inventory holder coupled to and/or supported by the mobile drive unit. The mobile drive unit is additionally capable of determining a location of the inventory holder and calculating a difference between the location of the inventory holder and the first point. The mobile drive unit is then capable of determining whether the difference is greater than a predetermined tolerance. In response to determining that the difference is greater than the predetermined tolerance, the mobile drive unit is also capable of moving to a second point on the basis of the location of the inventory holder, docking with the inventory holder, and moving the mobile drive unit and the inventory holder to the first point.SELECTED DRAWING: Figure 1
