Recently soft computing, which covers fuzzy, neuro, probabilistic reasoning, chaos, and evolutionary computation, has been studied in mechatronics by many researchers. Such research trends are summarized in this volume. The topics include fundamentals of control and learning, navigation, vision, multimedia, and several robotics implementation such as inverted pendulum, autonomous vehicle, and ping-pong robot. The contributors are leading experts from various countries. The book will be a great help to those who have an interest in mechatronics and soft computing, e.g., senior or graduate students and researchers in industry.
