Patent number: 7826919Abstract: 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 at least one of coupled to and 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 based on 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.Type: GrantFiled: June 9, 2006Date of Patent: November 2, 2010Assignee: Kiva Systems, Inc.Inventors: Raffaello D'Andrea, Peter K. Mansfield, Michael C. Mountz, Dennis Polic, Patrick R. Dingle
