Abstract

A motion simulating device which is capable of creating motion with up to six degrees of freedom; three rotational degrees of freedom and three linear-translational degrees of freedom. The motion simulating device includes a generally spherical capsule abuttively supported on a plurality of rollers that are connected to a translatable frame. At least one of the rollers is a multi-directional active roller that frictionally engages the capsule to impart rotational motion to the capsule in any direction. The frame is optionally attached to a number of actuator legs which are capable of translating the frame along three orthogonal axes. Optimally, sights, sounds and physical sensations may be electronically coordinated and reproduced in the capsule so that a user may interactively control and respond to a variety of environments while simultaneously experiencing the corresponding motion and physical sensations associated with the interactive environment.

Claims

1. A motion simulating device, comprising:

a generally spherical capsule;

a translatable frame for supporting said capsule, the translatable frame including a plurality of beams, a plurality of connecting joints and actuator legs, wherein each connecting joint is rigidly attached to two of said beams and each actuator leg is connected on one end to one of said connecting joints and on the other end to a supporting surface; and

a plurality of rollers connected to said frame and supportively abutting said capsule, wherein at least one of said rollers comprises an active roller for rotationally driving said capsule in any direction.

2. The motion simulating device of Claim 1, further comprising a means for interactively controlling the motion of said capsule and said frame.

3. The motion simulating device of Claim 2, wherein the interactive control means comprises:

a visual display;

a means for sensing the position of said capsule;

a means for coordinating the motion of said capsule and a representation of motion on said visual display; and

a means for controlling the motion of said capsule responding to a representation of motion of the user on said visual display.

4. The motion simulating device of Claim 3, further comprising:

a means for sensing the position of a user within said capsule;

a means for coordinating the motion of a user and a representation of motion on the visual display; and

a means for controlling said interactive solids responding to a representation of the motion of a user on visual display.

5. The motion simulating device of Claim 1, wherein said frame further comprises:

a plurality of beams;

a plurality of connecting joints, each rigidly attached to two of said beams; and

actuator legs, each connected on one end to one of said connecting joints and on the other end to a supporting surface for supporting.

6. The motion simulating device of Claim 1, wherein said connecting joints further comprise:

beam receptacles, each fixedly attaching one end of said beams to said connecting joint; and

a mounting plate for fixedly attaching one of said rollers to said connecting joint.

7. The motion simulating device of Claim 1, wherein said actuator legs further comprise a means for changing the length of said actuator legs.

8. The motion simulating device of Claim 7, wherein said means for changing the length of said actuator legs further comprises a hydraulic cylinder for telescoping a movable rod along the longitudinal axis of a support housing.

9. The motion simulating device of Claim 7, wherein said means for changing the length of said actuator legs further comprises a ball screw for telescoping a movable rod along the longitudinal axis of a support housing.

10. The motion simulating device of Claim 1, wherein said actuator legs are each rotatably connected on one end to one of said connecting joints and on the other end to a supporting surface.

11. The motion simulating device of Claim 1, wherein said active roller comprises:

a drive wheel rotatable about a drive axis generally parallel to a tangent to the surface of said capsule and frictionally engaging said capsule; and

a yoke for orienting the drive axis with respect to said capsule, said yoke being pivotable about an axis generally perpendicular to the drive axis.
