A self-balancing scooter is a self-balancing personal transporter consisting of two motorized wheels connected to a pair of articulated pads on which the rider places their feet.
The wheels of the hoverboard house the electric motors themselves. They also contain a tilt and speed sensor. This detects the rpm (revolutions per minute) of the individual wheel, and sends it to the gyroscope and speed control boards, located inside the main body, right next to the wheels.
