Abstract

In specific embodiments, a vehicle propellable through fluids or along surfaces, comprises a main work section and a plurality of propulsion units for propelling the main work section. The main work section supports one or more payloads. The propulsion units each include a rotor system and a ring-shaped wheel at least partially arranged about the rotor system and rotatable about the rotor system. The ring-shaped wheel is arranged at a banked angle relative to the rotor system.

Claims

1. A vehicle propellable through fluids or along surfaces, comprising:

a main work section for supporting one or more payloads;

a plurality of propulsion units for propelling the main work section, each of the propulsion units including

a rotor system,

a ring-shaped wheel at least partially arranged about the rotor system and rotatable about the rotor system; and

wherein the ring-shaped wheel is arranged at a banked angle relative to the rotor system; and

wherein when the vehicle is level and moving horizontally along a plane, for each of the propulsion units the banked angle is such that the ring-shaped wheel extends outside of the rotor system so that the ring-shaped wheel contacts, before the rotor system contacts, any surface perpendicular to or parallel to the plane.

2. The vehicle of claim 1, further comprising a ring-shaped hub at least partially arranged about the rotor system;

wherein the ring-shaped wheel is rotatable about the ring-shaped hub; and

a wheel motor connected with the ring-shaped hub for rotating the ring-shaped wheel.

3. The vehicle of claim 1, comprising four propulsion units approximately symmetrical arranged about the vehicle, and wherein each of the plurality of propulsion units is connected with the main work section by an arm frame.

4. The vehicle of claim 1, wherein the main work section includes

a payload support hub,

a payload support structure rotatable about the payload support hub, and

a core at least partially nested within the payload support hub, and

wherein the one or more payloads is mountable on the payload support structure.

5. A vehicle propellable through fluids or along surfaces, comprising:

a main work section for supporting one or more payloads;

a plurality of propulsion units for propelling the main work section, each of the propulsion units including

an arm frame extending from the main work section,

a rotor system connected with the arm frame, the rotor system including at least one rotor blade,

a ring-shaped hub connected with the arm frame and at least partially arranged about the at least one rotor blade, the ring-shaped hub having an inner diameter larger than the outer diameter of the at least one rotor blade, and

a ring-shaped wheel rotatable about the ring-shaped hub.

6. The vehicle of claim 5, wherein the main work section includes

a payload support hub,

a payload support structure rotatable about the payload support hub, and

a core at least partially nested within the payload support hub, and

wherein the one or more payloads is mountable on the payload support structure.

7. The vehicle of claim 5, further comprising a wheel motor connected with the ring-shaped hub for rotating the ring-shaped wheel.

wherein the ring-shaped wheel is arranged at a banked angle relative to the at least one rotor blade;

and

wherein when the vehicle is level and moving horizontally along a plane, for each of the propulsion units the banked angle is such that the ring-shaped wheel extends outside of the rotor system so that the ring-shaped wheel contacts, before the rotor system contacts, any surface perpendicular to or parallel to the plane.

8. The vehicle of claim 6, wherein the payload support structure allows multi-axis rotation of a mounted payload.

9. The vehicle of claim 6, wherein the one or more payloads includes one or more sensor payloads and/or one or more effector payloads.

10. The vehicle of claim 6, further comprising:

a hook connected with the payload support structure;

wherein the hook is adapted to catch a structure and support the vehicle on the structure.
