This project is based on the reflections by J. Borenstein and L.Feng, University of Michigan, June 27, 1996, Gyrodometry: A New Method for Combining Data from Gyros and Odometry in Mobile Robots.

Here two sites explaining well how gyroscopes work.

IKARUS   Profi-Gyro

This German gyro is normally used in model-helicopters.

It has a lot of interesting features: normal use for reaction to direction changes, heading-lock use, electronical sensitivity change, temperature compensation, control-LED, reverse motor

The gyro works with the ceramic gyro sensor from Tokin. When applying rotational angle velocity to an oscillating object, perpendicular to the oscillation direction a physical force is generated. The Tokin sensor uses this physical phenomenum.
