Sensor Input: Gyro
The navigation computer has an built-in Gyro, which is used to determine changes in direction of the vehicle. With the vehicle driving forward in a straight line the direction arrow should be pointing to the top of the screen. The Gyro value beside the direction icon should remain fairly constant. The vehicle should then be made to make a turn first to the right and then to the left. When the vehicle turns to the right, the direction icon should turn clockwise and the Gyro value should increase. The size of the angle through which the direction icon turns depends on the tightness of the turn. When the vehicle turns to the left, the direction icon should turn counterclockwise and the Gyro value should decrease.
