METHOD AND SYSTEM FOR TRANSPORTING INVENTORY ITEMS

摘要

Transporting of inventory items includes moving to a starting location associated with an inventory holder, docking with the inventory holder, and moving towards a destination location, while location of the inventory holder is determined. A difference between the determined location of the inventory holder and an anticipated location of the inventory holder is calculated and examined to determine if it is greater than a predetermined tolerance. If the difference is greater than the predetermined tolerance, then undocking from the inventory holder, determining a correction value based on the difference, wherein the correction value indicates at least one of a direction and a distance, moving based on the correction value docking with the inventory holder, and moving towards the destination location.
