This is a small and almost free of cost (about Indian Rs.30 ie 0.6 USD) experimental setup which demonstrates the idea of achieving stability in two-wheeled systems dynamically by using gyroscopic phenomenon.

The the reactive couple of the gyroscope is varied to balance the system by simply changing the voltage supply to the motors. The present setup is crude and can be developed further but is an example of prducing valid results at extremely low costs.
