Motion generation apparatus

A motion generation apparatus comprising:

• a platform comprising an occupant carrier;
• a base assembly having a first-direction set of tracks and an orthogonal second-direction set of tracks, the first-direction set of tracks being moveable in a direction along the second-direction tracks;
• three carriages mounted on the first-direction set of tracks and moveable in a direction along the first-direction, such that each carriage is independently moveable, within the plane containing the first and second directions, on the base assembly;
• three wishbone arms arranged to support the platform above the base assembly, each wishbone arm being connected at its lower, converged, end to a respective one of the carriages via a joint with three degrees of rotational freedom, and being connected at its upper, diverged, end to the platform at a revolute joint having a single degree of freedom about a pivot axis;
• and
• an actuation assembly for moving the first-direction tracks along the second-direction tracks and for moving the carriages along the first-direction tracks, thereby moving the occupant carrier in any or all of six available degrees of freedom.
