Abstract
This new invented mechanism is geometrically defined by two concentric tetrahedrons. Four motors are mounted onto the four vertexes of an outer tetrahedron frame. Four outer arc-links which are driven by these motors are pivotally connected with another four inner arc-links which are pivoted by four vertexes of an inner tetrahedron frame. This mechanism not only extends the range in pitch, roll and yaw three rotational DoF for enlarging the limits of Stewart 6-axis motion platform but also increases two translational DoF for improving the shortage of gimbals type multi-ring mechanism. This mechanism can simulate high maneuvering motion (ex. Barrel roll or fast spin) as high-speed vehicles (ex. fighter or roller coaster) can to stimulate passengers with virtual-but-real and shocked-but-exciting sensation. This mechanism will be chosen as a motion platform or a space orientating mechanism for a theme park game machine or a military fighter trainer.
