Robotic systems are those systems, which interact with their surroundings using actuators, sensors and human interfaces, and provide intelligent services and information. Mechatronics is a superset of robotic technologies and is defined as an interdisciplinary branch of engineering, which combines concepts from various disciplines including electrical and electronic engineering, mechanical engineering, computer science, and robotics. The model of mechatronics system is made up of two interacting submodels, which include a submodel describing the aspects of information flow in the control system and another one describing the aspects of energy flow in the physical system. This book contains some path-breaking studies on mechatronic and robotic systems. It is a collective contribution of a renowned group of international experts. In this book, using studies and examples, constant effort has been made to make the understanding of the difficult concepts of these systems as easy and informative as possible, for the readers.
