Stabilization of a two wheeled vehicle plays a vital role in today’s cluttered roads and congested transportation systems. Gyroscopically stabilized vehicles will provide greater safety than normal two wheelers, thereby leading to lesser number of casualties from road accidents.
There are two ways by which a two wheeled vehicle can be stabilized: dynamic stabilization and control motor gyroscope (CMG). This paper describes the working of the CMG technique in which the reactive precession torque of a high speed flywheel will act to balance the vehicle while keeping the rpm of the flywheel constant. In other words, when torque is applied to an axis normal to the spin axis, causing the gyroscope to precess, a moment is produced about a third axis, orthogonal to both the torque and spin axis. The resulting opposing reactive moment causes the stabilization of the vehicle.
A prototype with self-balancing mechanism has been modelled, fabricated and tested for the same. This paper proposes the mechanism to control and stabilize a two-wheeled prototype at zero forward velocity. The prototype has employed a single degree of freedom flywheel along with two types of motors- one to generate high rpm and the other to precess the axis of rotation.
