ABSTRACT:
A dual axis mechanically actuated motion platform which allows a user to move him or herself through a wide range of angular displacement in two intersecting axes individually or simultaneously by apply manual pressure to a lever in the direction of desired angular displacement. The motion platform is comprised of a base frame, a user support platform mounted on top of a universal joint, and a bearing mounted, preloaded offset linkage system coupled to a joystick lever. The offset linkage system creates enough increased mechanical advantage to move the seat platform in concert with the movement of the joystick lever, providing the user with the feeling of controlling an aircraft and the attendant sensations of pitch and roll motion.
