US Classification:

482 57, 482 51, 434 61, 434 55

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.
