Abstract
Gyro is well known as the application as Gyro-sensor. However Gyro is also used as an actuator such as: a gyro monorail in the beginning of 20^<Th> century, a research regarding of a gyro bike in 1970's. On the other hand, a self control bike using the inertia moment was proposed. Furthermore, when rifting a cargo by a crane, a rotating suppression system of it was developed as an application of Gyro-actuator. In this paper, we propose a self standing bike using Gyro-actuator which is controlled by a computer. First, a theory of 2-stage top using Euler's equation of the rotation coordinate is proposed. Next, the modeling of a bike using the 2-stage top theory is developed. Finally, the effect of this theory is confirmed by experiments.
