Abstract

Systems and methods are provided for swapping the battery on an unmanned aerial vehicle (UAV). The UAV may be able to identify and land on an energy provision station autonomously. The UAV may take off and/or land on the energy provision station. The UAV may communicate with the energy provision station. The energy provision station may store and charge batteries for use on a UAV.

First claim

What is claimed is:

1 . An unmanned aerial vehicle (UAV) battery changing station, said station comprising:
a UAV landing area configured to support a UAV when the UAV is resting on the station, said UAV coupled to a first battery configured to power the UAV, wherein the UAV landing area comprises a detectable marker configured to aid the UAV in landing; a battery storage unit comprising at least one holding station configured to store a battery capable of powering the UAV upon being coupled to the UAV; a communication unit in communication with the UAV and configured to receive a signal indicative of a remaining level of charge of the first battery; and one or more processors programmed to effect display of the detectable marker based at least on the remaining level of charge of the first battery, wherein the detectable marker is utilized to direct the UAV to land on the UAV landing area or to bypass the battery changing station.

2 . An unmanned aerial vehicle (UAV) battery changing station, said station comprising, said station comprising:
a UAV landing area configured to support a UAV when the UAV is resting on the station, said UAV coupled to a first battery configured to power the UAV, wherein the UAV landing area comprises a detectable marker configured to aid the UAV in landing; and a battery storage unit comprising at least one holding station each configured to store one or more batteries capable of powering the UAV upon being coupled to the UAV, wherein one or more processors are programmed to cause the detectable marker to indicate a state of charge of at least one battery stored in the battery storage unit.

3 . The battery changing station of claim 1 , wherein the landing area comprises multiple detectable markers configured to aid the UAV in landing or bypassing the battery changing station.

4 . The battery changing station of claim 1 , wherein the detectable marker is a raised pattern, a recessed pattern, an image, a symbol, a decal, a barcode, a QR code, or a light visible on the energy provision station landing area.

5 . The battery changing station of claim 2 , wherein the detectable marker is a raised pattern, a recessed pattern, an image, a symbol, a decal, a barcode, a QR code, or a light visible on the energy provision station landing area.

6 . The battery changing station of claim 1 , wherein the detectable marker comprises one or more images, wherein the images aid a UAV in landing when the UAV recognizes a particular image indicative that the UAV is to land.

7 . The battery changing station of claim 2 , wherein the detectable marker comprises one or more images, wherein the images aid a UAV in landing when the UAV recognizes a particular image indicative that the UAV is to land.

8 . The battery changing station of claim 1 , wherein the detectable marker comprises LED lights, wherein the LED lights flash in a specific spatial or temporal pattern that the UAV recognizes at the specific spatial or temporal pattern that is indicative that the UAV is to land.

9 . The battery changing station of claim 2 , wherein the detectable marker comprises LED lights, wherein the LED lights flash in a specific spatial or temporal pattern that the UAV recognizes at the specific spatial or temporal pattern that is indicative that the UAV is to land

10 . The battery changing station of claim 1 , wherein the detectable marker indicates an orientation of the UAV to be landed on the UAV landing area.

11 . The battery changing station of claim 10 , wherein the detectable marker is asymmetric to be indicative of the orientation.

12 . The battery changing station of claim 1 , wherein the detectable marker is indicative of the distance of the landing area relative to the UAV.

13 . The battery changing station of claim 1 , wherein the detectable marker is discernable to the UAV from above the UAV landing area.

14 . The battery changing station of claim 2 , wherein the detectable marker is discernable to the UAV from above the UAV landing area.

15 . The battery changing station of claim 1 , wherein the detectable marker is on an exterior surface of the battery changing station.

16 . The battery changing station of claim 2 , wherein the detectable marker is on an exterior surface of the battery changing station.

17 . The battery changing station of claim 1 , wherein the detectable marker is uniquely recognized by an approaching UAV.

18 . The battery changing station of claim 2 , wherein the detectable marker is uniquely recognized by an approaching UAV.

19 . The battery changing station of claim 1 , wherein the battery changing station emits intra-red (IR), ultra-violet (UV), radio, and/or audio signals.

20 . The battery changing station of claim 2 , wherein the battery changing station emits intra-red (IR), ultra-violet (UV), radio, and/or audio signals.

21 . A method of processing information from a battery changing station at an unmanned aerial vehicle (UAV), said method comprising:
detecting, by the UAV, a detectable marker from the battery changing station of claim 1 ; and generating, with aid of one or more processors at the UAV, a command signal that affects operation of the UAV based on the detection of the detectable marker.

22 . The method of claim 21 , wherein the command signal drives one or more propulsion units of the UAV.

23 . The method of claim 21 , wherein the command signal causes the UAV to land on the battery changing station after the UAV detects the detectable marker on the battery changing station, and wherein the UAV does not receive any other information from the battery changing station.

24 . The method of claim 21 , wherein the command signal causes the UAV to effect a choice between (1) bypassing the UAV landing area, or (2) landing on the UAV landing area, based on the detectable marker.

25 . The method of claim 24 , wherein the command signal is generated without any input by a user.

26 . A method of processing information from a battery changing station at an unmanned aerial vehicle (UAV), said method comprising:
detecting, by the UAV, a detectable marker from the battery changing station of claim 2 ; and generating, with aid of one or more processors at the UAV, a command signal that affects operation of the UAV based on the detection of the detectable marker.

27 . The method of claim 26 , wherein the command signal drives one or more propulsion units of the UAV to land on the UAV landing area when detectable marker is indicative that the one or more batteries stored in the battery changing station are fully charged.

28 . The method of claim 27 , wherein the UAV lands in an autonomous or semiautonomous fashion.

29 . The method of claim 26 , wherein the command signal does not drive one or more propulsion units of the UAV to land on the UAV landing area when the detectable marker is indicative that no battery on the battery changing station is fully charged.
