Adaptive thrust vector unmanned aerial vehicle
A method for unmanned delivery of an item to a desired delivery location includes receiving, at an unmanned vehicle, first data representative of an approximate geographic location of the desired delivery location, receiving, at the unmanned vehicle, second data representative of a fiducial expected to be detectable at the desired delivery location, using the first data to operate the unmanned vehicle to travel to the approximate geographic location of the desired delivery location, upon arriving at the approximate geographic location of the desired delivery location, using the second data to operate the unmanned vehicle to detect the fiducial; and upon detecting the fiducial, using the fiducial to operate the unmanned vehicle to deliver the item.
1. An unmanned aerial vehicle (UAV) comprising:
a fuselage;
one or more first spars coupled to the fuselage, and one or more first rotors each of which is mounted upon a respective first spar in a substantially horizontal position for providing vertical thrust for the UAV;
one or more second spars coupled to the fuselage, and one or more second rotors each of which is mounted upon a respective second spar in a substantially vertical position for providing horizontal thrust for the UAV;
wherein each of the second spars is rotatable relative to the one or more first spars.
2. The UAV of claim 1 , wherein each of the second spars is rotatable relative to the one or more first spars to alter flight characteristics of the UAV.
3. The UAV of claim 1 , wherein each of the second spars is rotatable relative to the one or more first spars when the UAV switches between hovering and a flying mode.
4. The UAV of claim 1 , wherein at least one second spar is longer than each first spar.
5. The UAV of claim 1 , wherein at least one second spar is rotatable to move the respective second rotor along a path around the one or more first rotors and the fuselage.
6. The UAV of claim 1 , wherein the UAV is operable to fly horizontally without using the one or more second rotors.
7. The UAV of claim 1 , wherein the fuselage is shaped to provide lift when the UAV flies in a lateral direction.
8. The UAV of claim 7 , wherein the UAV is operable to fly with the lift being provided by the fuselage without the one or more first rotors providing any additional lift.
9. The UAV of claim 7 , wherein the one or more first rotors are operable to provide additional lift in addition to the lift provided by the fuselage.
10. The UAV of claim 1 , wherein the UAV comprises a package bay, and the first and second spars extend from the package bay.
11. A method comprising:
operating one or more first rotors to provide lift to a UAV, each first rotor being mounted on a respective first spar coupled to a fuselage of the UAV;
operating one or more second rotors to provide horizontal thrust to the UAV, each second rotor being mounted on a respective second spar coupled to the fuselage; and
rotating at least one of the second spars relative to the one or more first spars.
12. The method of claim 11 , wherein rotating at least one of the second spars relative to the one or more first spars alters flight characteristics of the UAV.
13. The method of claim 12 , further comprising switching the UAV between hovering and a flying mode when rotating at least one of the second spars relative to the one or more first spars.
14. The method of claim 11 , wherein at least one second spar is longer than each first spar.
15. The method of claim 11 , wherein rotating at least one second spar relative to the one or more first spars rotates moves the respective second rotor along a path around the one or more first rotors and the fuselage.
16. The method of claim 11 , further comprising operating the one or more first rotors to fly the UAV horizontally without using the one or more second rotors.
17. The method of claim 11 , comprising flying the UAV horizontally while the fuselage provides lift.
18. The UAV of claim 17 , comprising flying the UAV horizontally without using the one or more first rotors while the fuselage provides lift.
19. The UAV of claim 17 , comprising flying the UAV horizontally without using the one or more first rotors while the fuselage provides lift and the one or more first rotors provide additional lift.
20. The UAV of claim 11 , wherein the UAV comprises a package bay, and the first and second spars extend from the package bay.
