Abstract

A method for using an unmanned aerial vehicle to install objects on wire and catenary structures is described. The method includes tagging the location, attaching the object to the UAV, navigating the UAV to the position, attaching the object, testing the attachment, releasing the object, inspecting the attachment, and returning the UAV to the ground. Sensors, flight control systems, means for attachment, and variations of embodiments of the methods, systems, and mechanical devices are described.

Claims

1. A method for attaching an object to a wire or catenary structure, comprising:

(a) identifying a target location on said wire or catenary structure;

(b) attaching said object to an unmanned aerial vehicle with a flight control system;

(c) navigating said unmanned aerial vehicle using said flight control system from ground to a location near said target location;

(d) positioning said unmanned aerial vehicle using said flight control system to a position such that said object can contact said target location;

(e) fastening said object to said wire or catenary structure using said flight control system;

(f) testing that said object is securely fastened to said wire or catenary structure;

(g) releasing said object; and

(h) returning said unmanned aerial vehicle to the ground.

2. The method of claim 1, further comprising inspecting the attachment of said object after it is fastened to said wire or catenary structure.

3. The method of claim 1, wherein said positioning of said unmanned aerial vehicle is assisted by the use of a gimbal mount.

4. The method of claim 1, wherein said flight control system uses a real time kinematic global positioning for navigating and positioning.

5. The method of claim 1, wherein said flight control system uses a local positioning system for navigating and positioning.

6. The method of claim 1, wherein said flight control system controls stability while said unmanned aerial vehicle exerts reverse thrust.

7. The method of claim 1, wherein said flight control system controls stability while said unmanned aerial vehicle is bottom-tethered to said wire or catenary structure.

8. The method of claim 1, wherein said flight control system controls for yaw while torque acts upon said unmanned aerial vehicle.

9. The method of claim 1, wherein said object is an aerial marker.

10. The method of claim 9, wherein said aerial marker has a wedge shaped opening to assist in positioning the unmanned aerial vehicle for fastening the aerial marker.

11. The method of claim 9, wherein said aerial marker has downward facing V-guides to assist in positioning the unmanned aerial vehicle for fastening the aerial marker.

12. The method of claim 1, wherein fastening said object includes the fastening of an automatic cable fastener to secure said object in place on said wire or catenary structure.

13. The method of claim 1, wherein said flight control system uses at least one of the following sensors to assist in navigating and positioning:

3D motion sensors, an RFID interrogator identifying said target location, a laser or lidar rangefinder, an infrared sensor, or mechanical feelers.

14. The method of claim 1, wherein said unmanned aerial vehicle uses at least one of the following to assist in fastening said object:

an imaging device detecting fastening, an electrical signal indicating fastening, a signal from the flight control system indicating fastening, a strain gauge indicating fastening.

15. The method of claim 1, wherein said unmanned aerial vehicle uses at least one of the following to assist in fastening said object:

automatic mechanical latch, automatic magnetic latch, an electrically-controlled latch, an automated screwdriver, an automated socket wrench, a take-up wire spool, a gravity-actuated clasp, a spring-driven clamp, screwing together sleeved semi-spheres or hemispheres, driving a geared winch, closing a grapple, automated mechanical wire grips, pressurized air, an exploding bolt which releases an automatic fastening action, applying adhesive, activating a servo, activating a solenoid.

16. A unmanned aerial vehicle comprising:

a flight control system;

a platform for mounting an object on a wire or catenary structure;

sensors for navigating to specific location;

a means for attaching said object to a wire or catenary structure;

a means for testing that said object is securely attached to said wire or catenary structure;

a means for releasing said object.

17. The unmanned aerial vehicle of claim 16, wherein the object is an aerial marker.

18. The unmanned aerial vehicle of claim 16, further comprising a gimbal mount.

19. The unmanned aerial vehicle of claim 16, wherein said means for attaching said object is an automatic cable fastener.

20. The unmanned aerial vehicle of claim 16, wherein said flight control system uses a real time kinematic global positioning or a local positioning system.
