Driven by the need to achieve superior control performances for robots with hyper degrees of freedom, the virtual decomposition control approach is thoroughly presented in this book. This approach uses subsystem (such as links and joints of a complex robot) dynamics to conduct control design, while guaranteeing the stability and convergence of the entire complex robot without compromising the rigorousness of the system analysis. The central concept of this approach is the definition of the virtual stability. The stability of the entire complex robot is mathematically equivalent to the virtual stability of every subsystem. This fact allows us to convert a large problem to a few simple problems with mathematical certainty.

This book comprises fourteen chapters. The first five chapters form the foundation of this approach. The remaining nine chapters are relatively independent. Starting from Chapter 6, each chapter deals with a particular type of systems including motor/transmission assemblies, hydraulic robots, coordinated multiple robots, space robots, humanoid robots, adaptive teleoperation, and modular robot manipulators. At the end, the extensions of this approach to distributed-parameter systems and to electrical circuits are given, paving the way for other applications to follow.

This book is intended for practitioners, researchers, and graduate students who have acquired fundamental knowledge on robotics and control systems and have been committed to achieving the best control performances on complex robotics systems and beyond.

Digital Media, Online Activism, and Social Movements in Korea deepens the current understanding of online activism and its impacts on society by highlighting how various forms of social movements have been mobilized in Korea. Through exploring movements in Korea such as political participation based on SNS, the 2008 U.S. beef protests, and the 2016-2017 candlelight vigils, the contributors study the intersection of digital media platforms, current trends, and social, cultural, and political conditions within Korean society. Using a wide range of events and movements, this book analyzes how people have utilized the development of digital media to facilitate social movements and effect social change.
