Abstract

A motion platform system includes a support and a motion platform supported by the support and rotatable about a plurality of bearing axes. The motion platform is further rotatable with respect to the support about at least one axis that is offset from the plurality of bearing axes. The motion platform may include an intermediate frame supported by the support, where the intermediate frame is rotatable about a first bearing axis with respect to the support. The motion platform may further include an inner frame supported by the intermediate frame, where the inner frame is rotatable about a second bearing axis with respect to the intermediate frame. Rotations of the inner and intermediate frames about the first and second bearing axes facilitate rotation of the inner frame with respect to the support about at least one axis offset from the bearing axes.

Claims

1. In a motion platform system including a motion platform supported by a support and rotatable about a plurality of bearing axes, wherein said motion platform includes an intermediate frame supported by said support and an inner frame supported by said intermediate frame, a method of manipulating said motion platform comprising:

(a) rotating said motion platform about at least one axis that is offset from said plurality of bearing axes, wherein step (a) includes;

(a.1) rotating said intermediate frame about a first bearing axis with respect to said support; and

(a.2) rotating said inner frame about a second bearing axis with respect to said intermediate frame;

wherein rotation of said inner and intermediate frames about said first and second bearing axes facilitate rotation of said inner frame with respect to said support about at least one of a third axis and a fourth axis.

2. The method of claim 1, further comprising:

(b) supporting at least one user on said inner frame.

3. The method of claim 1, wherein said system further includes a base supporting said support, and wherein the method further comprises:

(b) moving said support in at least one direction with respect to said base.

4. The method of claim 3, wherein step (b) includes:

(b.1) rotating said support with respect to said base.

5. The method of claim 1, wherein said first and second bearing axes are substantially perpendicular to each other and said third and fourth axes are respectively offset from said first and second bearing axes.

6. The method of claim 1, wherein said system further includes at least one actuator, and wherein the method further comprises:

(b) actuating said at least one actuator to facilitate rotations of said inner and intermediate frames about respective first and second bearing axes.

7. The method of claim 6, wherein said at least one actuator includes first and second actuators, and wherein step (b) includes:

(b.1) actuating said first actuator to effect rotation of said intermediate frame about said first bearing axis; and

(b.2) actuating said second actuator to rotate said inner frame about said second bearing axis.

8. The method of claim 7, wherein step (b.1) includes:

(b.1.1) moving said first actuator in a first direction to effect rotation of said intermediate frame about said first bearing axis; and

step (b.2) includes;

(b.2.1) moving said second actuator in said first direction to effect rotation of said inner frame about said second bearing axis;

wherein the first and second actuators are moved simultaneously to facilitate a rotation of said inner frame with respect to said support about said third axis.

9. The method of claim 7, wherein step (b.1) includes:

(b.1.1) moving said first actuator in a first direction to facilitate rotation of said intermediate frame about said first bearing axis; and

step (b.2) includes;

(b.2.1) moving said second actuator in a second direction that differs from said first direction to facilitate rotation of said inner frame about said second bearing axis;

wherein the first and second actuators are moved simultaneously to facilitate rotation of said inner frame with respect to said support about said fourth axis.

10. The method of claim 6, wherein said system further includes a controller, and wherein the method further comprises:

(c) controlling rotations of said intermediate and inner frames about said first and second bearing axes via said controller in response to actuation of said at least one actuator.

11. The method of claim 6, wherein said system further includes a monitor, and wherein the method further comprises:

(c) displaying information relating to system operation via said monitor.

12. The method of claim 11, wherein said system further includes a controller, and wherein the method further comprises:

(d) controlling said monitor, via said controller, to display a virtual reality scenario that changes based upon user manipulation of said system.

13. The method of claim 12, wherein said system further includes an exercise assembly, and wherein the method further comprises:

(e) facilitating manipulation of said exercise assembly to exercise a user body during system operation.

14. The method of claim 13, wherein said exercise assembly includes a cycling assembly, and step (e) further includes:

(e.1) facilitating manipulation of said cycling assembly by user feet to exercise a user lower body during system operation.

15. The method of claim 13, wherein said system further includes at least one sensor in communication with said controller, and the method further comprises:

(f) measuring manipulation of at least one of said inner frame, said intermediate frame, said at least one actuator and said exercise assembly via said at least one sensor; and

(g) sending measured information from said at least one sensor to said controller.

16. The method of claim 13, wherein said system further includes at least one resistance member, and wherein the method further comprises:

(f) adjusting resistance, via said at least one resistance member, to at least one of said intermediate frame, said inner frame, said at least one actuator and said exercise assembly to simulate conditions within said virtual reality scenario.
