The disclosed inventory systems and methods can be used to retrieve and transport items from one location in an inventory system to another. Specifically, an unmanned aerial vehicle (UAV) including passive buoyancy element, a thrust unit, and a retention feature, can be controlled by a management component to retrieve one or more items, transport the item or items, and deposit the item or items. For example, a UAV can be controlled to obtain an item at one location in a warehouse such as a first floor and lift said item to a second location in the warehouse such as a second floor, and deposit the item at the second location.

1. An inventory management system, comprising: a plurality of unmanned aerial vehicles (UAVs), wherein an unmanned aerial vehicle (UAV) of the plurality of unmanned aerial vehicles comprises: a first shell arranged to enclose a volume of lighter-than-air gas and comprising a plurality of ducts extending between a superior surface of the shell to an inferior surface of the shell;a plurality of fans to control movement of the UAV disposed within the plurality of ducts; anda retention feature connected with the inferior surface of the shell to retain a container; anda management component configured with executable instructions, in order to, at least: receive information relating to an item in an inventory system;instruct the UAV to move to a first location above the item;instruct the UAV to retain the item; andinstruct the UAV to move the item to a second location. 2. The system of claim 1, wherein the UAV further comprises a ballast subsystem; and wherein the management component is further configured with executable instructions in order to: cause the ballast subsystem to adjust a quantity of ballast in a ballast container based in part on a net weight of the UAV, the net weight being based in part on at least one or more of a weight of the UAV, a weight of an item, and a buoyant force of the volume of lighter-than-air gas. 3. The system of claim 1, wherein the UAV further comprises a sensor to sense an environment of the UAV; and wherein the management component further comprises: a locator module to determine a position of the unmanned aerial vehicle at least in part based on the environment; anda pathfinding module for determining a route for travel by the unmanned aerial vehicle. 4. The system of claim 3, further comprising: an inventory management facility having at least two floors, wherein the pathfinding module is operable to determine a route for travel between two different floors of the at least two floors. 5. A computer-implemented method of managing inventory, the method comprising: receiving information identifying an inventory item to be retrieved;identifying a location of the inventory item;selecting, via a computer system, an unmanned aerial vehicle (UAV) from a plurality of unmanned aerial vehicles (UAVs), the plurality of UAVs each comprising one or more passively buoyant elements and a plurality of thrust units; andinstructing the UAV to retrieve the inventory item. 6. The computer-implemented method of claim 5, wherein instructing the UAV to retrieve the inventory item further comprises providing instructions via a wireless network. 7. The computer-implemented method of claim 5, wherein instructing the UAV to retrieve the inventory item further comprises instructing the UAV to retrieve at least a top portion of an inventory holder containing the inventory item. 8. The computer-implemented method of claim 5, wherein instructing the UAV to retrieve the inventory item further comprises instructing the UAV to retrieve a container containing the item. 9. The computer-implemented method of claim 8, further comprising: transferring the inventory item to be transferred to a docking station; andinstructing the UAV to retrieve the container from the docking station. 10. The computer-implemented method of claim 5, further comprising: detecting a weight associated with the inventory item; andtransferring a quantity of ballast of the UAV based in part on the weight. 11. The computer-implemented method of claim 5, further comprising: determining a vertical net force on the UAV; andtransferring a quantity of ballast of the UAV at a docking station based in part on the vertical net force. 12. The computer-implemented method of claim 5, further comprising adjusting a power output of the plurality of thrust units by changing a direction of the power output of the plurality of thrust units. 13. The computer-implemented method of claim 5, further comprising: instructing the UAV to transfer the item to a destination; andinstructing the UAV to release the item at the destination. 14. An inventory system comprising: a plurality of items in an inventory management facility;a plurality of docking stations in the inventory management facility configured to receive one or more items of the plurality of items; andan unmanned aerial vehicle (UAV) comprising: a shell containing a passive buoyancy element;a thrust element connected with the shell;a retention element connected with the shell, the retention element being operable to retain one or more of the plurality of items; anda management component configured with executable instructions to control the UAV in order to, at least: receive a request to retrieve an item of the plurality of items; andinstruct the unmanned aerial vehicle to retrieve the item. 15. The system of claim 14, wherein the management component is further configured with executable instructions to control the UAV in order to, at least: instruct the UAV to move to a location above a first docking station, retain the item; transport the item to a second docking station; and release the item at the second docking station. 16. The system of claim 15, wherein the management component is further configured with executable instructions to control the UAV in order to, at least: detect a payload weight of a payload; andadjust a ballast quantity of a ballast based in part on the payload weight. 17. The system of claim 14, wherein the management component is further configured with executable instructions to control the UAV in order to, at least: detect a payload weight of a payload; anddetermine that the payload weight is greater than a maximum payload weight; andinstruct a support UAV to dock with the UAV, such that the UAV and the support UAV are arranged to provide a combined lifting force on the payload. 18. The system of claim 14, wherein the management component is further configured with executable instructions to control the UAV in order to, at least: instruct the UAV to move to a first location above a first inventory holder containing the item; retain the item; move to a second location above a second inventory holder; and deposit the item at the second inventory holder. 19. The system of claim 14, wherein the UAV further comprises one or more sensors; and wherein the management component is further configured with executable instructions to control the UAV in order to, at least: detect, via the sensors, an environment around the UAV; anddetermine a route of travel for the UAV based in part on the environment around the UAV. 20. The system of claim 19, wherein the request to retrieve an item further comprises a request to transfer the item from an origin floor of a multilevel inventory management facility to a destination floor of the multilevel inventory management facility, the origin and destination floors being different floors of the inventory management facility.
