A motion translating apparatus which may be used in a motion simulator or in a motion controlling device has an x axis, a y axis and a z axis, each of which axes is perpendicular to each other. The apparatus may include a base having a central leg substantially i n the "z" axis; at least three shaft and ball assemblies associated with each leg, each assembl y including a ball having a spherical outer surface and a centreline parallel to the "x-y" plan e, and a rotating shaft fixed to the ball parallel to but offset from the centreline of the ball; wherein the axes of the shafts converge on a centre point and radiate outward from the leg and where in rotation of the shaft displaces the ball eccentrically about the axis of the shaft; and a platform which has an outer circumference and at least three receptacles, wherein each receptacle engages a corresponding ball such that movement of each ball causes movement of the platform; and means for independently rotating each shaft associated with the base or legs .
