Steering
The One-Wheeled Vehicle
 
The steering system for the one-wheeled vehicle is fairly simple. It utilizes a gyroscope which is mounted at the rear end of the vehicle, on the right side, and turns about an axis in the lateral (left to right) direction. The steering wheel is in the front of the vehicle, on the left side. As the wheel is turned, that motion is transferred to a long rod, which in turn, affects the motion of a lever at the rear left side of the vehicle. Attached to this lever, is a threaded rod, which is attached to a handwheel, so that the gyroscope position may be manually adjusted, ensuring that the gyroscopic weight wheel has an angular velocity direction perpendicular to that of the longitudinal axis of the vehicle. The rod, as affected by the motion of the lever, can impart to the gyroscope, a moment in the z-direction (up and down), causing angular acceleration in the third (lateral) direction, allowing the vehicle to turn.
