Dynamics of the Unicycle
Author: Michał Niełaczny
Publisher: Springer
ISBN: 3319953842
Category : Technology & Engineering
Languages : en
Pages : 85
Book Description
This book presents a three-dimensional model of the complete unicycle–unicyclist system. A unicycle with a unicyclist on it represents a very complex system. It combines Mechanics, Biomechanics and Control Theory into the system, and is impressive in both its simplicity and improbability. Even more amazing is the fact that most unicyclists don’t know that what they’re doing is, according to science, impossible – just like bumblebees theoretically shouldn’t be able to fly. This book is devoted to the problem of modeling and controlling a 3D dynamical system consisting of a single-wheeled vehicle, namely a unicycle and the cyclist (unicyclist) riding it. The equations of motion are derived with the aid of the rarely used Boltzmann–Hamel Equations in Matrix Form, which are based on quasi-velocities. The Matrix Form allows Hamel coefficients to be automatically generated, and eliminates all the difficulties associated with determining these quantities. The equations of motion are solved by means of Wolfram Mathematica. To more faithfully represent the unicyclist as part of the model, the model is extended according to the main principles of biomechanics. The impact of the pneumatic tire is investigated using the Pacejka Magic Formula model including experimental determination of the stiffness coefficient. The aim of control is to maintain the unicycle–unicyclist system in an unstable equilibrium around a given angular position. The control system, based on LQ Regulator, is applied in Wolfram Mathematica. Lastly, experimental validation, 3D motion capture using software OptiTrack – Motive:Body and high-speed cameras are employed to test the model’s legitimacy. The description of the unicycle–unicyclist system dynamical model, simulation results, and experimental validation are all presented in detail.

Book Description
This book tells the story of cyclists who were overcome by the need to venture into the wild on two wheels; the courageous men and women who undertook some of the most epic bicycle journeys of all time. Wild Ride reminds us of a thrilling period of exploration all but forgotten in the age of the motorcar. Daniel Oakman takes us on a rich ride through 130 years of Australian cycling; from the overlanding heroes of Arthur Richardson and Francis Birtles, to the lesser known but no less amazing feats of Jerome Murif, Ted Ryko and Joe Pearson, through to modern-day bikepacking trailblazers such as Kate Leeming, Tegan Streeter and Tom Richards.
