Abstract:
1. A motion platform, comprising: a stationary frame with at least three uprights; a sub-frame disposed substantially within the stationary frame; at least three connecting members for connecting each upright with the sub-frame at a respective connection point, wherein each connecting member comprises an arm, a first coupling, and a second coupling, wherein the first coupling couples a first end of the arm to at least one of said uprights of the stationary frame, and wherein the second coupling couples a second end of the arm to the sub-frame at said connection point; a cabin, connected to the sub-frame, and being suitable for accommodating a person; a plurality of actuators; wherein the sub-frame, the connecting members, and the cabin form a jointed structure configured to enable a translational motion and at least one of the group consisting of a pitch, a yaw, and a roll of said cabin with respect to the stationary frame by means of the plurality of actuators engaging the structure; wherein the sub-frame and connecting members are configured such that, during use, each of the connection points is at a substantially fixed distance with respect to a common central point of the sub-frame; wherein the first coupling of at least one of the connecting members is movably mounted to the relevant upright to allow vertical displacement of the first coupling relative to the upright; and wherein, during use, the connection points are moveable with respect to each other to change the distances between them, and wherein each connection point is moveable along a respective circle relative to the sub-frame.
