Abstract

A package delivery system for delivering a plurality of packages with one or more unmanned aerial vehicles (UAVs) includes a package receptacle to receive and store the plurality of packages. A charging station charges a plurality of UAV batteries which power the one or more UAVs. A UAV landing pad permits the one or more UAVs to land thereon. A loader loads a package of the plurality of packages and/or a UAV battery of the plurality of UAV batteries onto the UAVs when the UAVs are on the UAV landing pad. A transporter moves the packages and/or the UAV batteries s toward the loader.

First claim

What is claimed is:

1. A system for handling a package, the system comprising:
an UAV powered by a battery;
a receptacle configured to store the package;
a charging station to charge the battery;
a landing pad engaged with the UAV during transfer of the package and the battery to and from the UAV; and
a transporter configured to transfer at least one of the package and the battery between the UAV and a loader, wherein the loader is configured to transfer at least one of the package and the battery between the transporter and the receptacle and the charging station, respectively.

2. The system of claim 1 , wherein the battery that is transferred from the UAV is at least partially discharged.

3. The system of claim 2 , wherein the battery lacks a sufficient charge to power the UAV during a delivery of the package.

4. The system of claim 1 , wherein the battery that is transferred from the UAV is fully charged.

5. The system of claim 4 , wherein a battery that is fully charged has a sufficient charge to power the UAV during a delivery of the package and a return journey of the UAV to the charging station.

6. The system of claim 1 , wherein the package contains a pharmaceutical payload, and wherein the battery that is fully charged based on a weight of the pharmaceutical payload.

7. The system of claim 1 , wherein the landing pad selectively, magnetically couples with UAV.

8. The system of claim 1 , wherein the landing pad includes a holder, wherein the UAV includes a skid that selectively engages the holder.

9. The system of claim 8 , wherein the landing pad selectively, magnetically couples with the UAV when the skid engages the holder.

10. The system of claim 8 , wherein the UAV is equipped with at least one sensor to detect a characteristic of the landing pad.

11. The system of claim 10 , wherein the UAV positions and orients itself based on the characteristic detected by the at least one sensor such that the skid engages the holder.

12. The system of claim 11 , wherein the characteristic is an inscription on the landing pad.

13. The system of claim 1 , wherein the UAV is spaced from the transporter by a total distance including:
a first reach distance between the transporter and the loader; and
a second reach distance between the UAV and the loader.

14. The system of claim 1 , wherein the UAV is spaced from the transporter by at least one of a first reach distance between the transporter and the loader, and a second reach distance between the UAV and the loader.

15. A method for handling a package, the method comprising:
transferring a package between a receptacle and a transporter;
transferring the package between the transporter and a loader;
transferring a battery between a charging station and the transporter;
transferring the battery between the transporter and the loader; and
transferring at least one of the package and the battery between the loader and a UAV while the UAV is docked with a landing pad.

16. The method of claim 15 further including:
determining that the battery is fully charged such that the battery has a sufficient charge to power the UAV to and from a delivery;
in response to determining the battery is fully charged, transferring the battery that is fully charged from the charging station to the UAV; and
in response to determining that battery is insufficiently charged to power the UAV to and from a delivery, transferring the battery from the UAV to the charging station.

17. The method of claim 15 further including
detecting, by a sensor in communication with the UAV, a characteristic of the landing pad;
adjusting the UAV to an orientation and a position based on detecting the characteristic; and
engaging a skid coupled with the UAV with a holder coupled with the landing pad.

18. The method of claim 17 further including magnetically coupling the UAV with the landing pad.

19. The method of claim 17 further including magnetically coupling the skid with the holder.

20. The method of claim 15 , wherein the steps of transferring at least one of the package and the battery between the transporter and the UAV includes transferring the at least one of the package and the battery a first reach distance between the transporter and the loader.

21. The method of claim 20 , wherein the steps of transferring at least one of the package and the battery between the transporter and the UAV further includes transferring the at least one of the package and the battery a second reach distance between the loader and the UAV.
