A method, apparatus and system of a motion simulator is disclosed. In one embodiment, a motion simulator not resorting to conventional principles nor employing any fluid or pneumatic components to derive motion with 6 degrees of freedom. Motion derived from bi-directional low voltage motors controlled through a Human Computer Interface Device is described which achieves 120 degrees of "Pitch & Roll" through rotation of ball screws acting through "spherical ball joints". "Yaw", "Rising and Descending" independently achieved through "rack and pinions" acting upon the central spherical pivot and rotational plates. The lower "spherical ball joints" firmly securing the ball screw's bearings, motor and coupling, the upper spherical ball joints mounted on slide-able bearing plates which encase the ball nut. The above providing proportionality between two sets of (ball screws) linear actuators. Rotation induced into the "spherical ball-joint" opposed to the direction of motor and screw is overcome by employing a "hardening peg", "bearing" and "track" sunk into a surface of the "spherical ball-joint".
