The Segway accomplished its awesome self-balancing with the aid of gyroscopic sensors.A gyroscope is a spinning disc that is free to move in all directions.
When you measure the gyroscope spinning, you can measure how far the person leans on a Segway, and by noting which sensor is activated – what direction.
For example, if a person leans forward, it gets measured and the wheels spin faster to make the Segway accelerate (and keeping it balanced at the same time).
