Abstract: A method for cycle counting warehouse inventory using a drone system with a drone carrying a scanning device and a computer with an RF session receiving cycle count tasks. The drone system is placed within a flight range of the drone to a cycle count location and flown to the cycle count location of the cycle count task. The drone acquires the inventory location data and sends it to a warehouse management system through the RF session. Then the drone acquires the inventory data and sends it to a warehouse management system through the RF session. If prompted by the warehouse management system, further data are acquiring such as SKU data, LPN attribute information, and/or quantity information.
