After traveling a set distance (known as the reach), the gyro mechanism kicks in. It senses that the ring and the axis of the gyroscope are not aligned. Via a connection to the torpedo's two ...

However, mechanical gyroscopes tend to drift over time and therefore include a mechanism to keep the spin axis upright with respect to the direction of gravity. The ADI42-124 uses an entirely ...

The gyroscope is the key to how it works - it uses something called gyroscopic precession which can be tricky to understand. This video explains the car and the mechanism inside. US Congress ...
