Abstract

A reconfigurable system capable of autonomously exchanging material from unmanned vehicles of various types and sizes. The system comprises an environmental enclosure, a landing area, a universal mechanical system to load and unload material from the unmanned vehicle, and a central processor that manages the aforementioned tasks. The landing area may comprise a one or more visible or non-visible markers/emitters capable of generating composite images to assist in landing the unmanned vehicle upon the reconfigurable, autonomous system.

Claims

1. A reconfigurable power station for unmanned aerial vehicles (UAV), comprising:

an enclosure defining a surface;

one or more modular power bays positioned within the enclosure, the modular power bay defining one or more receiving bays for retaining a corresponding swap cartridge;

a landing zone positioned upon the surface and sized to receive one or more UAVs, wherein the landing zone has one or more markers or emitters configured to generate one or more composite images which change in size in a manner corresponding to a proximity of the UAV relative to the landing zone;

a central processor in communication with the one or more markers or emitters; and

a universal swap cartridge processor positionable upon the UAV and which is in communication with the central processor.

2. The power station of claim 1 further comprising one or more swap cartridges positioned within the one or more receiving bays.

3. The power station of claim 1 further comprising a modular power bay status monitor configured to monitor a status of the corresponding swap cartridge.

4. The power station of claim 1 further comprising a swapping mechanism configured to load and/or retrieve a swap cartridge between the one or more receiving bays and the UAV situated upon the landing zone.

5. The power station of claim 1 further comprising a sensor system in communication with the central processor and configured to optically determine an orientation of the UAV relative to the landing zone.

6. The power station of claim 1 further comprising a transmitter and receiver in communication with the central processor for transmitting and receiving data via a communication network.

7. The power station of claim 1 further comprising a mechanical connector and an electrical connector positioned upon the landing zone and configured for attachment to the UAV after positioning upon the landing zone.

8. The power station of claim 1 wherein the one or more markers or emitters are configured to emit visible or invisible signals when the UAV is in proximity to the landing zone.

9. The power station of claim 1 wherein the swap cartridge further comprises an integrated marker unique to the swap cartridge for tracking one or more parameters of the swap cartridge.

10. The power station of claim 1 wherein the one or more composite images are scalable to reduce in size as the UAV approaches to the landing zone.

11. The power station of claim 1 further comprising at least one UAV which is positionable upon the landing zone.

12. A method of swapping a power supply in an unmanned aerial vehicle (UAV), comprising:

receiving a request from a UAV by a reconfigurable power station (RPS);

emitting one or more composite images to the UAV via one or more markers or emitters when the UAV is in proximity to a landing zone located on the RPS;

changing a size of the one or more composite images to correspond to a proximity of the UAV relative to the landing zone;

determining an orientation of the UAV relative to the landing zone after the UAV has landed;

removing a first swap cartridge from the UAV via a swapping mechanism within the RPS; and

installing a second swap cartridge from the RPS and into the UAV.

13. The method of claim 12 wherein receiving a request comprises transmitting the request via a universal swap cartridge processor positioned within or upon the UAV.

14. The method of claim 13 further comprising receiving mission or payload data from the UAV via the universal swap cartridge.

15. The method of claim 12 further comprising establishing a mechanical link with the UAV prior to removing a first swap cartridge.

16. The method of claim 15 further comprising establishing an electrical link with the UAV.

17. The method of claim 12 wherein determining an orientation of the UAV comprises determining an orientation of the UAV, which may or may not comprise optically determining the orientation.
