Abstract

An unmanned vehicle is provided. The unmanned vehicle includes a navigation system configured to navigate the unmanned vehicle relative to a beam of energy emitted from a beam source, a power receiver configured to receive energy from the beam, and an energy storage system configured to store received energy for use in selectively powering the unmanned vehicle.

Claims

1. An unmanned vehicle comprising:

a navigation system configured to navigate said unmanned vehicle relative to a beam of energy emitted from a beam source;

a power receiver configured to receive energy from the beam; and

an energy storage system configured to store received energy for use in selectively powering said unmanned vehicle.

2. An unmanned vehicle in accordance with claim 1, wherein said unmanned vehicle is an unmanned aerial vehicle (UAV).

3. An unmanned vehicle in accordance with claim 1 further comprising a vehicle propulsion system configured to propel said unmanned vehicle, said vehicle propulsion system comprising at least one motor and at least one positioning device.

4. An unmanned vehicle in accordance with claim 1 further comprising:

a control system; and

a vehicle propulsion system, said control system configured to control a position of said unmanned vehicle using said vehicle propulsion system.

5. An unmanned vehicle in accordance with claim 4, wherein said control system comprises a power management and distribution system for use in selectively allocating power to said unmanned vehicle.

6. An unmanned vehicle in accordance with claim 1, wherein said power receiver comprises at least one of a photovoltaic array and a rectenna.

7. An unmanned vehicle in accordance with claim 1, wherein said navigation system is further configured to:

measure an amount of energy stored in said energy storage system; and

guide said unmanned vehicle to the beam of energy when the energy stored is below a pre-determined threshold.

8. An unmanned vehicle in accordance with claim 1, wherein said navigation system is further configured to utilize at least one of global positioning system (GPS) coordinates, visual cues, and radio signals, to navigate said unmanned vehicle.

9. An unmanned vehicle in accordance with claim 1 further comprising a position control system configured to enable fine positioning of said unmanned vehicle.

10. An unmanned vehicle in accordance with claim 9, wherein said position control system is further configured to measure a power output of said power receiver.

11. An unmanned vehicle in accordance with claim 10, wherein said position control system is further configured to measure a time associated with each power output measurement.

12. An unmanned vehicle in accordance with claim 9, wherein said position control system comprises an inertial measurement unit and at least one sensor configured to measure a relative position of said unmanned vehicle.

13. An unmanned vehicle in accordance with claim 12, wherein said at least one sensor comprises a camera configured to detect at least one of object features and optical beacons.

14. A vehicle system comprising:

a beam source configured to emit a beam of energy; and

an unmanned vehicle comprising a navigation system, a power receiver, and an energy storage system, said navigation system configured to position said unmanned vehicle relative to the beam, said power receiver configured to receive energy from the beam, said energy storage system configured to store received energy for use in powering said unmanned vehicle.

15. A system in accordance with claim 14, wherein said beam source comprises a locating system configured to aid said unmanned vehicle in locating the beam.

16. A system in accordance with claim 15, wherein said locating system comprises a global positioning system (GPS).

17. A system in accordance with claim 14, wherein said beam source comprises a position reference system configured to substantially center said unmanned vehicle relative to said beam.

18. A system in accordance with claim 17, wherein said position reference system comprises at least one of a local reference signal and a set of object features visible to a camera coupled to said unmanned vehicle.

19. A system in accordance with claim 14, wherein said beam source comprises a proximity activation system, said beam source activated when said unmanned vehicle is within a predefined distance from said beam source.

20. A system in accordance with claim 19, wherein said proximity activation system comprises at least one of an acoustic sensor configured to recognize a sound emitted by said unmanned vehicle, a visual sensor configured to recognize an appearance of said unmanned vehicle, and a radio configured to receive positional data from said unmanned vehicle.
