| Abstract: |
A simulator system for use in providing an event simulation to an occupant includes a motion base moveable only along three mutually orthogonal displacement axes by means of displaceable actuators. An audio-visual display mechanism is included for providing a sequence of audio and visual images to the occupant. A motion base controller generates actuator drive signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images. The projected visual images including "foreground" and "background" portions. The system controller generates the motion base command signals such that the displacement of the motion base is synchronized to the onset of movement of the foreground image and the foreground image is constrained to move, relative to the occupant, only along the same three orthogonal axes as the motion base.

I claim:
1. A three axis orthogonal motion base for use with a simulator system having a system controller that generates command signals for presentation of a sequence of audio-visual image signals to a simulator system occupant synchronously with the movement of the motion base, said motion base comprising:
- a base member fixed to provide a foundation, said base member having a base member interface surface;
- a lower member adapted to be received by said base member interface surface along a cooperative first lower member interface surface to be moveable relative thereto substantially in a first linear direction;
- cooperatively engaging base and lower displacement guide elements respectively affixed to said base member interface surface and said first lower member interface surface for constraining said base and lower members to substantially linear relative movement in said first direction;
- first actuator means communicating with said base and lower displacement guide elements for effecting displacement of said base and lower members relative to one another in response to received first actuator drive signals;
- a middle member adapted to be received by a second lower member interface surface along a cooperative first middle member interface surface to be moveable relative to said lower member substantially in a second direction orthogonal to said first direction, said middle member having an interior cavity;
- cooperatively engaging lower and middle displacement guide elements respectively affixed to said second lower member interface surface and said first middle member interface surface for constraining said lower and middle members to substantially linear relative movement in said second direction;
- second actuator means communicating with said lower and middle displacement guide elements for effecting displacement of said lower and middle members relative to one another in response to received second actuator drive signals;
- a platform adapted to receive ride simulation apparatus upon an upper platform surface;
- cooperatively engaging middle and platform displacement guide elements respectively affixed to said second middle member interface surface and a platform interface surface for constraining said middle member and platform to substantially linear relative movement in a third direction orthogonal to both said first and second directions, said middle and platform displacement guide elements extending fully below said upper platform surface and adapted to be received within said middle member cavity; and
- a third actuator means communicating with said middle and platform displacement guide elements extending fully below said upper platform surface and adapted to be received within said middle member cavity for effecting displacement of said platform relative to said middle member in response to received actuator drive signals.
