Detection of Similarity of Trajectory of Center of Gravity in Operating Unicycle Uses Motion Capture System

摘要

Riding a unicycle is good exercise to enhance and keep riderȁ9;s sense of equilibrium, reflexes and quickness. But a lot of people can not ride a unicycle because its stability. And there are no theoretically to be able to ride a unicycle. A way to do so is that, at first, the model of riding unicycle is simply considered as the cart-pendulum model, then using inputs and outputs obtained by measured data of Motion Capture System(MCS), its controller is able to derived. But a relationship between riderȁ9;s body manipulations and movements of center of gravity are not unique. because there a lot of way to make same trajectory of center of gravity by different body manipulations. Therefore, in this paper, to understand a way to ride a unicycle by the relationship, a way to decide the similarity of movements of center of gravity is described.
