Abstract: A motion simulator uses an existing personal computer and off the shelf software to physically simulate and control the motions of a computer generated vehicle. The motion simulator is manually powered by the user and includes a control stick connected to an input to the computer whereby movement of the control stick is translated into movement of the computer generated vehicle. A rigid control arm connects the control stick to a base unit and to a cockpit frame to move the cockpit frame relative to the base unit as the control stick is moved. The control stick also contains buttons which provide additional inputs to the computer generated vehicle. Foot operated pedals are also connected to the computer program and to the cockpit to move the cockpit in conjunction with movement of a computer generated vehicle. A throttle lever unit is also connected to the computer to control the computer generated vehicle.
