US Patent 11307574 Unmanned aerial vehicle fleet management

An unmanned aerial vehicle (UAV) includes one or more sources of propulsion coupled to provide propulsion to the UAV, and a power source coupled to power the one or more sources of propulsion. A communication system is coupled to communicate with an external device, and a controller is coupled to the communication system, the power source, and the one or more sources of propulsion. The controller includes logic that when executed by the controller causes the UAV to perform operations, including: measuring a status of the UAV; sending the status of the UAV to the external device; receiving movement instructions from the external device; and engaging the one or more sources of propulsion to move the UAV from a first location to a second location within a storage facility.
