The invention is a hovercraft with multiple lift chambers which are operable independently of each other. Independently-operable pivot arm assemblies connect each lift chamber to the hovercraft main body, and his gives the hovercraft the ability to travel over uneven surfaces, traverse obstacles that would block conventional hovercrafts, and climb or descend even severe inclines. The hovercraft also includes side thrusters which allow it to maintain its vertical position on an incline while traveling laterally across the incline.

1. A hovercraft, comprising: (a) a main body;(b) a plurality of lift chambers attached to the main body, with at least two of the lift chambers being operable independently of each other;(c) means for providing lift to the lift chambers;(d) means for providing forward motion to the hovercraft; and(e
1. A hovercraft, comprising: (a) a main body;(b) a plurality of lift chambers attached to the main body, with at least two of the lift chambers being operable independently of each other;(c) means for providing lift to the lift chambers;(d) means for providing forward motion to the hovercraft; and(e) arms that connect the at least two lift chambers to the main body, the arms being adapted to raise or lower the at least two lift chambers with respect to the main body, and the arms being separate and distinct from the at least two lift chambers;wherein the hovercraft can traverse uneven surfaces and surmount obstacles. 2. The hovercraft of claim 1, wherein at least two of the lift chambers are movable with respect to the main body, independently of each other, and wherein a plane formed by the bottom of one lift chamber can have a different angle, with respect to the main body, than a plane formed by the bottom of another lift chamber. 3. The hovercraft of claim 1, wherein all the lift chambers are movable with respect to the main body, independently of each other, so that a plane formed by the bottom of one lift chamber can have a different angle with respect to the main body than a plane formed by the bottom of another lift chamber. 4. The hovercraft of claim 3, wherein arms connect all the lift chambers to the main body, and the arms raise or lower the lift chambers with respect to the main body, and the arms are separate and distinct from the lift chambers. 5. The hovercraft of claim 1, wherein a first lift pressure supplied to at least one of the lift chambers is different than a second lift pressure supplied to another of the lift chambers. 6. The hovercraft of claim 1, wherein the means for providing lift is a blower. 7. The hovercraft of claim 1, wherein the means for providing forward motion is at least one thruster. 8. The hovercraft of claim 7, wherein the at least one thruster is rotatable to provide backward motion to the hovercraft. 9. The hovercraft of claim 1, wherein the hovercraft also comprises at least one side thruster to impart side force to the hovercraft. 10. The hovercraft of claim 9, wherein the at least one side thruster is rotatable, to offset other forces acting on the hovercraft or provide additional lift to the hovercraft. 11. The hovercraft of claim 1, wherein the hovercraft also comprises at least one wheel that is extended to enable wheeled operation of the hovercraft and retracted when wheeled operation is not desired. 12. The hovercraft of claim 1, wherein the hovercraft also comprises at least one hydrofoil that is extended to enable hydrofoil operation of the hovercraft and retracted when hydrofoil operation is not desired. 13. The hovercraft of claim 1, wherein the hovercraft also comprises at least one accelerometer for controlling a motion of the hovercraft. 14. The hovercraft of claim 1, wherein the hovercraft also comprises at least one gyroscope for controlling a motion of the hovercraft. 15. The hovercraft of claim 1, wherein the hovercraft also comprises a global positioning system for controlling a motion of the hovercraft. 16. A method of surmounting an obstacle with a hovercraft, comprising the steps of: providing a hovercraft with a main body; a plurality of lift chambers attached to the main body with at least two of the lift chambers being operable independently of each other; arms that connect at least two of the lift chambers to the main body, the arms being adapted to raise or lower the at least two lift chambers with respect to the main body, and the arms being separate and distinct from the at least two lift chambers; means for providing lift to the lift chambers; and means for providing forward motion to the hovercraft;approaching the obstacle, raising a first lift chamber until the first lift chamber clears the obstacle, then moving the hovercraft forward toward the obstacle until the first lift chamber has surmounted the obstacle;raising a second lift chamber until the second lift chamber clears the obstacle, then moving the hovercraft forward toward the obstacle until the second lift chamber has surmounted the obstacle. 17. The method of claim 16, wherein the method also comprises the step of raising a third lift chamber until the third lift chamber clears the obstacle, then moving the hovercraft forward toward the obstacle until the third lift chamber has surmounted the obstacle. 18. The method of claim 16, wherein the method also comprises using thrusters to provide additional lift to the hovercraft. 19. The method of claim 16, wherein the means for providing forward motion is at least one thruster.
