Abstract: The invention relates to a motion generator comprising an end effector which moves relative to a surface, the end effector being moved by at least six actuation mechanisms, in which each actuation mechanism comprises an elongate tensioned member connected at one of its ends to the end effector, whereby the end effector is suspended above the surface by the tensioned members, and at the other of its ends to an associated rocker of the same actuation mechanism, whereby the rocker is mounted to be pivotable about an axis which is fixed relative to the surface, and in which, when a rocker is actuated, the associated tensioned member and the end effector are moved. The invention also relates to motion systems and simulators comprising such motion generators, as well as to methods of operation and production.
