Here is a preface for a multi-author book titled Robotics: Modelling, Planning and Control. Preface The field of robotics is undergoing a profound transformation, moving beyond its traditional role in manufacturing to become an integral part of our daily lives. From autonomous vehicles and medical robots to assistive devices and drones, robotics is shaping the future of technology and human-machine interaction. This rapid expansion demands a comprehensive understanding of the core principles that govern robotic systems. It is this need that inspired the creation of Robotics: Modelling, Planning and Control. This book is a collaborative effort by a diverse group of researchers and engineers, each a specialist in their respective areas of robotics. Our goal was to create a resource that bridges the gap between theoretical foundations and practical applications. We recognized that no single author could provide the depth and breadth required to cover the entire subject effectively. By pooling our expertise, we have crafted a text that offers a holistic view of modern robotics, from the fundamental mathematics of robot kinematics to the cutting-edge algorithms used for motion planning and control. The book is structured into three main sections to guide readers logically through the subject. Part I: Modelling lays the groundwork by introducing the mathematical tools necessary to describe the motion and configuration of robotic manipulators. This section covers kinematics, dynamics, and sensors, providing the essential language of robotics. Part II: Planning delves into how robots make decisions. Here, we explore topics such as trajectory generation, path planning in complex environments, and the critical role of perception in a robot's ability to navigate its world. Finally, Part III: Control focuses on the methods used to make a robot execute a desired action. This section covers classical and modern control techniques, as well as force and impedance control, which are vital for robots that interact with their environment. Our primary audience is graduate students, researchers, and practicing engineers who wish to deepen their knowledge of robotics. We assume a basic familiarity with linear algebra, calculus, and introductory physics. While each chapter can be studied independently, the book is designed to be read sequentially to build a solid, interconnected understanding of the subject. Throughout the text, we have included numerous examples, exercises, and illustrations to make complex concepts more accessible. We would like to express our sincere gratitude to the many colleagues, students, and institutions whose work has influenced our own. We also thank our families for their patience and support during the writing process. It is our hope that this book will not only serve as a valuable reference but will also inspire the next generation of roboticists to push the boundaries of what is possible. The journey of creating this book has been a testament to the power of collaboration. We are proud to present a work that reflects the collective expertise and passion of the robotics community. We invite you to explore these pages and join us in the exciting pursuit of building a smarter, more capable, and more autonomous future.
