The invention relates to a motion platform system comprises a motion platform 2 which is supported above a base 4 by displacement units 6. Displacement units 6 comprise a drive unit 8 which drives a crank 12. A connecting arm 14 is connected between the crank 12 and the motion platform 2, so that translational and tilting movement of the motion platform 2 is achieved by appropriate operation of the drive units 8. Each connecting arm 14 has a curved profile which enables a full range of movement of the motion platform 2 to be achieved using connecting arms 14 of relatively short length. The connection between the connecting arm 14 and the crank arm 12 can be brought close to, or within, the crank arm 12. The height of the motion platform 2 above the base 4, and bearing loads within the drive units, can thus be reduced. |
