The „Racing Sim D2“ is a motion rig with two degrees of movement: Pitch and Roll. The user is offered an immersive racing experience via a force feedback steering wheel and a moving chair. Received values are sent to the motors and influence the player's position, which changes accordingly. The simulation depicts G-forces, such as those that occur when accelerating, decelerating or steering. Various functions can be selected using buttons and a display on the side of the simulator. This interface is also used for error output. In the event of an error, the motors are de-energised, but the microcontroller remains powered and can therefore be used to detect errors.
