Base stations including integrated systems for servicing UAVs

1. A base station for an unmanned aerial vehicle (UAV), the base station comprising:

an enclosure including:

an outer housing defining a roof section; and

an inner housing connected to the outer housing;

a cradle repositionable in relation to the enclosure between a retracted position, in which the cradle is positioned within the enclosure, and an extended position, in which the cradle is exposed from the enclosure to thereby receive the UAV during landing, wherein the cradle is movable along an axis extending in generally perpendicular relation to a landing direction of the UAV during repositioning between the retracted position and the extended position;

one or more heating elements supported by the roof section and thermally connected thereto to thereby heat the roof section;

one or more fiducials supported by the enclosure;

an illumination system supported by the enclosure and configured to illuminate the one or more fiducials; and

a visualization system supported by the enclosure.

2. The base station of claim 1 , wherein the enclosure defines one or more channels configured to direct water in a manner inhibiting entry into the base station.

3. The base station of claim 1 , further comprising one or more temperature sensors in communication with the one or more heating elements such that the one or more heating elements are activated upon receiving a signal relayed by the one or more temperature sensors indicating that temperature has crossed a threshold.

4. The base station of claim 1 , wherein the one or more fiducials include a first fiducial and a second fiducial each supported by the roof section, the second fiducial being removably connected to the roof section.

5. The base station of claim 4 , wherein the first fiducial defines a first surface area, and the second fiducial defines a second surface area less than the first surface area.

6. The base station of claim 5 , wherein the first surface area lies substantially within a range of approximately 40 percent to approximately 80 percent of a surface area defined by the roof section.

7. The base station of claim 6 , wherein the second surface area lies substantially within a range of approximately 10 percent to approximately 50 percent of the first surface area.

8. The base station of claim 4 , wherein the illumination system includes one or more light sources secured to the roof section and configured to light the first fiducial and the second fiducial.

9. The base station of claim 8 , wherein the illumination system is configured to strobe the one or more light sources according to a pattern recognizable by the UAV during approach to thereby identify the base station.

10. The base station of claim 1 , wherein the visualization system includes a digital image capturing device configured to identify precipitation and actuate the one or more heating elements.

11. A base station for an unmanned aerial vehicle (UAV), the base station comprising:

an enclosure including:

an outer housing; and

an inner housing connected to the outer housing, the inner housing defining an internal cavity configured to receive the UAV;

a door movably connected to the enclosure such that the door is repositionable between a closed position and an open position; and

one or more actuators extending between the door and the enclosure, wherein each actuator includes:

a motor assembly secured to the inner housing such that the motor assembly is located between the outer housing and the inner housing; and

a linkage assembly extending between the motor assembly and the door, the linkage assembly extending through the inner housing.

12. The base station of claim 11 , wherein the linkage assembly includes:

a drive screw operatively connected to the motor assembly such that actuation of the motor assembly causes rotation of the drive screw;

a carrier threadably engaged to the drive screw such that rotation of the drive screw causes axial translation of the carrier;

a first arm having a first end and a second end, the first end being pivotably connected to the carrier; and

a second arm having a first end and a second end, the first end of the second arm being pivotably connected to the second end of the first arm and the second end of the second arm being pivotably connected to the door.

13. The base station of claim 12 , further including a bracket fixedly connected to the door, the bracket being pivotably connected to the second end of the second arm.

14. The base station of claim 12 , wherein the drive screw is configured such that rotation of the drive screw in a first direction causes advancement of the carrier towards the door and rotation of the drive screw in a second direction causes advancement of the carrier away from the door.

15. The base station of claim 12 , wherein the drive screw includes threading defining a pitch configured to inhibit force transmission from the door to the carrier to thereby maintain the door in the closed position.

16. A base station for an unmanned aerial vehicle (UAV), the base station comprising:

an enclosure defining an internal cavity configured to receive the UAV, wherein the internal cavity is concealed when the base station is in a first configuration and the internal cavity is exposed when the base station is in a second configuration;

a first fiducial supported by a roof section of the enclosure, the first fiducial defining a first surface area;

a second fiducial supported by the roof section of the enclosure and separated from the first fiducial when the base station is in both the first configuration and the second configuration, the second fiducial defining a second surface area less than the first surface area; and

an illumination system supported by roof section and configured to illuminate the first fiducial and the second fiducial.

17. The base station of claim 16 , wherein the second fiducial is configured for removable connection to the roof section.

18. The base station of claim 16 , wherein the first surface area lies substantially within a range of approximately 40 percent to approximately 80 percent of a surface area defined by the roof section.

19. The base station of claim 18 , wherein the second surface area lies substantially within a range of approximately 10 percent to approximately 50 percent of the first surface area.

20. The base station of claim 16 , wherein the illumination system is configured to strobe according to a pattern recognizable by the UAV during approach to thereby identify the base station.
