Abstract

According to certain embodiments, a device comprises a body, a mechanical propulsion system affixed to the body to cause the body to traverse a multi-oriented surface and to prevent contact between the body and the multi-oriented surface, a thrust system to apply a thrust force to the device that opposes a gravitational force acting on the device, and a payload with at least one sensor to detect a characteristics of the multi-oriented surface.

First claim

The invention claimed is:

1. A device comprising:
a body;
a mechanical propulsion system affixed to the body, the mechanical propulsion system comprising a plurality of wheels and at least one motor coupled to the plurality of wheels, wherein the mechanical propulsion system is configured to:
cause the body to traverse a multi-oriented surface; and
prevent contact between the body and the multi-oriented surface;

a ducted fan configured to apply a thrust force to the device, wherein the thrust force opposes a gravitational force acting on the device;
a suspension system affixing the mechanical propulsion system to the body, the suspension system comprising a plurality of actuators configured to:
lift the body of the device over a protrusion of the multi-oriented surface;
adjust the orientation of the body; and
raise and lower each of the plurality of wheels with respect to the body in order to maintain contact between the mechanical propulsion system and the multi-oriented surface; and

a payload comprising at least one sensor configured to detect one or more characteristics associated with the multi-oriented surface.

2. The device of claim 1 , wherein the ducted fan is further configured such that a magnitude of a vertical component of the thrust force exceeds the gravitational force.

3. The device of claim 1 , wherein the ducted fan comprises a plurality of control vanes configured to:
control the direction of the thrust force; and
cause the thrust force to act upon a point on the device, with respect to a center of gravity of the device.

4. The device of claim 1 , wherein the suspension system is further configured to adjust the orientation of the body such that the direction of the thrust force is more incidental to the direction of the gravitation force.

5. The device of claim 1 , wherein the suspension system is further configured to adjust the orientation of the body such that the direction of the thrust force is more opposed to the direction of slide of the mechanical propulsion system.

6. The device of claim 1 , wherein the ducted fan is further configured to control the thrust force so as to cause the suspension system to adjust the orientation of the body.

7. The device of claim 1 , wherein the suspension system is further configured to raise the body to a distance away from the multi-oriented surface in response to a topology of the multi-oriented surface.

8. The device of claim 1 , wherein the ducted fan is further configured to lessen a vacuum pressure resultant on the multi-oriented surface.

9. The device of claim 1 , wherein the payload comprises at least one of a visual-spectrum camera, an infrared camera, a thermal camera, a laser scanner, an X-ray module, and an ultrasonic non-destructive testing module.

10. The device of claim 1 , further comprising a marking device configured to mark a defect of the multi-oriented surface.

11. A system for detecting characteristics associated with a multi-oriented surface comprising:
at least one device, wherein each of the at least one device comprises:
a body;
a mechanical propulsion system affixed to the body, the mechanical propulsion system comprising a plurality of wheels and at least one motor coupled to the plurality of wheels, wherein the mechanical propulsion system is configured to:
cause the body to traverse a multi-oriented surface; and
prevent contact between the body and the multi-oriented surface;

a ducted fan configured to apply a thrust force to the at least one device, wherein the thrust force opposes a gravitational force acting on the at least one device;
a suspension system affixing the mechanical propulsion system to the body, the suspension system comprising a plurality of actuators configured to:
lift the body of the device over a protrusion of the multi-oriented surface;
adjust the orientation of the body; and
raise and lower each of the plurality of wheels with respect to the body in order to maintain contact between the mechanical propulsion system and the multi-oriented surface; and

at least one sensor configured to detect characteristics associated with the multi-oriented surface; and
a controller configured to control the at least one device and further configured to detect one or more characteristics associated with the multi-oriented surface based at least in part on the at least one sensor.

12. The system of claim 11 , wherein at least one device further comprises at least one tool.

13. The system of claim 12 , wherein the tool comprises at least one of a paint applicator, a sealant applicator, a glue applicator, a sanding apparatus, a deburring apparatus, a cutting apparatus, a welding apparatus, a rivet applicator, a marker, a sticker applicator, a repair tool, and a tool delivery system.

14. A method of detecting characteristics comprising:
traversing a multi-oriented surface with at least one device, the at least one device comprising:
a body;
a mechanical propulsion system affixed to the body, the mechanical propulsion system comprising a plurality of wheels and at least one motor coupled to the plurality of wheels, wherein the mechanical propulsion system is configured to:
cause the body to traverse the multi-oriented surface; and
prevent contact between the body and the multi-oriented surface; and

a ducted fan configured to apply a thrust force to the at least one device, wherein the thrust force opposes a gravitational force acting on the at least one device;
a suspension system affixing the mechanical propulsion system to the body, the suspension system comprising a plurality of actuators configured to:
lift the body of the device over a protrusion of the multi-oriented surface;
adjust the orientation of the body; and
raise and lower each of the plurality of wheels with respect to the body in order to maintain contact between the mechanical propulsion system and the multi-oriented surface; and

detecting, by at least one sensor, one or more characteristics associated with the multi-oriented surface.

15. The method of claim 14 , wherein the step of traversing the multi-oriented surface with at least one device further comprises directing by at least one of manual control, semi-autonomous control, and autonomous control.

16. The method of claim 15 , wherein the step of directing further comprises communicating to the at least one device by at least one of a tethered wire and a wireless communications protocol.

17. The method of claim 15 , wherein the step of directing is determined based at least in part on a path selected to reduce energy expenditure by at least one of the mechanical propulsion system and the thrust system.

18. The method of claim 14 , further comprising responding to the one or more characteristics, wherein responding comprises at least one of painting, gluing, sealing, sanding, deburring, cutting, welding, riveting, marking, repairing, and applying a sticker.
