Abstract
A six degree of freedom (DOF) motion platform system is described that, in contrast to Stewart platforms, is adapted to include redundant load paths or to be without non-redundant load paths. During operation of the six DOF motion platform system, a controller may employ motion control software to provide desired movement of a ride vehicle supported on the upper plate or motion platform of the system. This makes the six DOF motion platform system particularly well suited for use in amusement or theme park rides and similar applications where it is desirable to provide redundant load paths because this reduces significant design constraints and also lowers fabrication and maintenance/operation costs when compared to rides using Stewart platforms. The actuation system used in the motion platform system include four pairs of linear actuators arranged as a rectangular truss instead of a more conventional triangular truss used in six DOF motion platforms.
