Abstract

A two-wheel gyroscope-stabilized vehicle includes a stabilizing gyroscope, having a gyroscope frame and a gyroscope rotor rotatably mounted in the frame. The gyroscope frame is free to rotate relative to the vehicle body. The vehicle further comprises a support structure that connects the vehicle body and the vehicle wheels, wherein the supporting structure is adapted to move the wheels independently in relation to each other and to move the wheels in relation to the body independently thereof. The support structure helps to keep the vehicle stable when riding on rough terrain. Balancing of the vehicle is provided by maintaining a right angle between the axis of rotation of the gyroscope rotor and direction of the vehicle movement by means of the control system through changing the difference of rotation velocities of the wheels. Steering of the vehicle is provided by means of applying the roll control force to the body.
