摘要： A system for transporting inventory includes an inventory holder (30) and a mobile drive unit (20). The inventory holder includes a frame capable of storing inventory items and a docking plate (350) capable of receiving a docking head (110) from underneath. The mobile drive unit, includes a docking head capable of coupling to the docking plate and a drive module capable of propelling the mobile drive unit (120). The mobile drive unit is further capable to move the inventory holder when the docking head is coupled to the inventory holder.

摘要： A system (10) for transporting inventory items (40) includes an inventory holder (30) capable of storing inventory items and a mobile drive unit (20). 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..
