Robots are designed to perform a complex series of tasks automatically. The field which deals with design, operation, construction and use of robots is referred to as robotics. It is an interdisciplinary field of science and engineering which includes mechanical engineering, information engineering, computer science and electronic engineering. Robotics utilizes computer systems for sensory feedback, information processing and to control robots. They are especially used in the situations that are dangerous for humans such as in manufacturing processes, bomb detection and deactivation, high heat, space and clean-up of hazardous materials and radiations. Industrial robots, mobile robots, modular robots, collaborative robots, service robots and educational robots are the examples of the most commonly used modern robots. This book presents the complex subject of robotics in the most comprehensible and easy to understand language. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. Through this book, we attempt to further enlighten the readers about the new concepts in this field.
