Abstract

Disclosed is a drone capable of operating in an aqueous environment. The drone may include a buoyant structure configured to provide buoyancy. Further, the drone may include one or more propulsion units configured to propel the drone. Furthermore, the drone may include an upper camera disposed on an upper side of the drone. Additionally, the drone may include a lower camera disposed on a lower side of the drone. Further, each of the upper camera and the lower camera may be configured to capture images. Furthermore, one or more legs configured to enable the drone to stand on a solid surface. Additionally, the drone may include one or more leg-actuators coupled to the one or more legs. Further, the one or more leg-actuators may be configured to change a state of the one or more legs to one of an extended state and a retracted state.

a lower camera configured to capture images, wherein the lower camera is disposed on a lower side of the drone;

at least one leg configured to enable the drone to stand on a solid surface; and

at least one leg-actuator coupled to the at least one leg, wherein the at least one leg-actuator is configured to change a state of the at least one leg to one of an extended state and a retracted state.

2. The drone of claim 1, wherein an optical axis of the upper camera is coincident with an optical axis of the lower camera.

3. The drone of claim 1, wherein each of the upper camera and the lower camera is configured to capture images simultaneously.

4. The drone of claim 1, wherein the buoyant structure comprises a spherical enclosure configured to enclose each of the upper camera and the lower camera.

5. The drone of claim 1, wherein the buoyant structure comprises a propeller protector.

6. The drone of claim 4, wherein the at least one leg comprises a plurality of legs, wherein each leg comprises an extension portion and a foot portion, wherein a first end of the extension portion is connected to at least a portion of the spherical enclosure, and wherein a second end of the extension portion is connected to the foot portion.

7. The drone of claim 1, further comprising:

a transceiver configured to communicate data; and

a processor configured to control at least one of the following;

the at least one propulsion unit, the upper camera, the lower camera, the at least one leg-actuator, the transceiver, and a buoyancy of the buoyant structure.

8. The drone of claim 1, further comprising an enclosure configured to enclose each of the upper camera, the lower camera, a transceiver, and a processor, wherein the enclosure is hermetically sealed.

9. The drone of claim 7, further comprising at least one proximity sensor, wherein the processor is configured to control the at least one propulsion unit based on an output of the at least one proximity sensor.

10. The drone of claim 1, further comprising at least one gimbal configured to support at least one of the upper camera and the lower camera.

11. The drone of claim 1, wherein the at least one propulsion unit comprises at least one motor and at least one propeller.

12. The drone of claim 1, further comprising a Global Positioning System (GPS) receiver.

13. The drone of claim 1, further comprising a wireless controller configured to control operation of the drone, the wireless controller comprising:

an input device configured to receive a control input;

a transceiver configured to communicate data, wherein the data comprises each of the control input and images captured by at least one of the upper camera and the lower camera; and

a display device configured to display images captured by at least one of the upper camera and the lower camera.

14. The drone of claim 1, wherein the at least one propulsion unit is configured to enable the drone to lift off from water.

15. The drone of claim 1, further comprising at least one camera-actuator configured to control at least one of a position and an orientation of at least one of the upper camera and the lower camera.

16. The drone of claim 7, wherein the processor is further configured to:

perform image processing of images captured by at least one of the upper camera and the lower camera; and

control at least one of the at least one propulsion unit, the upper camera, the lower camera, the at least one leg-actuator and the transceiver based on a result of the image processing.

17. The drone of claim 1, wherein the drone is configured to float on a water body with one of the upper side and the lower side facing towards the surface of the water body.

18. The drone of claim 1, wherein the at least one leg is configured to enable the drone to stand on the solid surface with one of the upper side and the lower side facing towards the solid surface.

25. The drone of claim 16, wherein the image processing comprises detection of at least one of a solid body and a water body, wherein the processor is further configured to control the at least one leg-actuator based on the detection.

26. The drone of claim 25, wherein the processor is further configured to perform image correction on images captured by at least one of the upper camera and the lower camera facing towards a water body, wherein image correction compensates for a water based distortion in the images, wherein the water based distortion is caused by optical properties of the water body.

19. A drone capable of operating in aqueous environment, the drone comprising:
