Abstract

The current technique provides an unmanned vehicle that is capable of travelling in the air, on the ground and/or in the water. The driving force of the unmanned vehicle is provided by at least one propelling module that includes a motor, a shaft and a propeller. The propelling module is coupled to a chassis. The chassis includes one or more support elements that each couples to one or more aileron member. An aileron member is configured to tilt with or about the support element to change fluid flux about the aileron member and thus change a position of the propelling force.

First claim

What is claimed is:

1. An unmanned vehicle, comprising:
a chassis;
a propelling module coupled to the chassis;
at least one moveable member coupled to the chassis through a support element and a flexible coupling element, the at least one moveable member being moveable to change a position of the propelling module relative to a movement path of the unmanned vehicle;
at least two wheels coupled to the chassis, each of the at least two wheels configured to freely rotate with respect to the chassis; and
a controller that, when in operation, controls a movement of the at least one moveable member.

2. The unmanned vehicle of claim 1 , wherein the chassis and the propelling module are structured to be fixed with respect to one another to move as a whole relative to the movement path of the unmanned vehicle.

3. The unmanned vehicle of claim 1 , wherein the flexible coupling element coupling the at least one moveable member through to the chassis is at least one hinge.

4. The unmanned vehicle of claim 1 , wherein the at least one moveable member includes a first moveable member and a second moveable member, the first moveable member coupled to the chassis through a first hinge arranged in a first direction, the second moveable member coupled to the chassis through a second hinge arranged in a second different direction.

5. The unmanned vehicle of claim 4 , wherein the first direction and the second direction are substantially perpendicular to one another.

6. The unmanned vehicle of claim 3 , wherein the at least one hinge is an elastic hinge.

7. The unmanned vehicle of claim 1 , wherein the at least two wheels are structured to float in a liquid medium.

8. The unmanned vehicle of claim 7 , wherein the at least two wheels each includes at least one of a low-density material or an inner tube.

9. The unmanned vehicle of claim 1 , further comprising one or more sensors that detect an operational environment of the unmanned vehicle.

10. The unmanned vehicle of claim 1 , further comprising a pay load module coupled to the chassis, the pay load module including a communication interface capable of coupling to the controller.

11. The unmanned vehicle of claim 1 , wherein the propelling module includes a motor, a shaft and a propeller, the shaft being substantially perpendicular to an axis between two wheels of the at least two wheels.

12. An unmanned vehicle, comprising:
a chassis;
a propelling module rigidly coupled to the chassis in a fixed relationship, the propelling module including a motor, a shaft and a propeller;
at least two aileron members coupled to the chassis through a support member and a flexible coupling element, each aileron member being configured to change air flux thereabout through tilting;
a rotatable connecting member between the chassis and the aileron members that permit the entire chassis to rotate when the air flux changes as the ailerons tilt; and
a controller that in operation controls the tilting of the aileron member.

13. The unmanned vehicle of claim 12 , wherein the chassis includes a frame arranged outside the propelling module, and an aileron member of the at least two aileron members is coupled to the frame.

14. The unmanned vehicle of claim 12 , wherein an aileron member of the at least two aileron members is coupled to the chassis through the support element and the flexible coupling element, the support element configured to rotate about a longitudinal axis thereof.

15. A method of operating an unmanned vehicle, comprising:
detecting, by a sensor, an operation environment of the unmanned vehicle travelling in a first path, the unmanned vehicle including a propelling module and multiple aileron members coupled to the propelling module through a support member and a flexible coupling member;
selecting an operation state of the unmanned vehicle based on the detected operation environment; and
tilting one or more of the multiple aileron members to change a position of the propelling module relative to the first path based on the selected operation state.

16. The method of claim 15 , further comprising controlling a rotation speed of a propeller of the propelling module.

17. The method of claim 15 , wherein the selecting the operation state of the unmanned vehicle includes selecting a ground travelling mode over a flying mode and a floating mode as long as the detected operation environment allows.

18. The method of claim 17 , wherein the tilting the one or more of the multiple aileron members including maintaining the propelling module to stay in a position for ground traveling based on that the detected operation environment is suitable for ground travelling.

19. The method of claim 16 , wherein the controlling a rotation speed of the propeller is based on the detected operation environment.

20. The method of claim 15 , wherein the detecting the operation environment includes detecting an obstacle on the first path of the unmanned vehicle.
