Snake Robots

Snake Robots is a novel treatment of theoretical and practical topics related to snake robots: robotic mechanisms designed to move like biological snakes and able to operate in challenging environments in which human presence is either undesirable or impossible. Future applications of such robots include search and rescue, inspection and maintenance, and subsea operations. Locomotion in unstructured environments is a focus for this book. The text targets the disparate muddle of approaches to modelling, development and control of snake robots in current literature, giving a unified presentation of recent research results on snake robot locomotion to increase the reader’s basic understanding of these mechanisms and their motion dynamics and clarify the state of the art in the field. The book is a complete treatment of snake robotics, with topics ranging from mathematical modelling techniques, through mechatronic design and implementation, to control design strategies. The development of two snake robots is described and both are used to provide experimental validation of many of the theoretical results. Snake Robots is written in a clear and easily understandable manner which makes the material accessible by specialists in the field and non-experts alike. Numerous illustrative figures and images help readers to visualize the material. The book is particularly useful to new researchers taking on a topic related to snake robots because it provides an extensive overview of the snake robot literature and also represents a suitable starting point for research in this area.

The book is written by professors and doctoral researchers from the Norwegian University of Science and Technology. The authors are also associated with SINTEF, which is a Norwegian research organization that conducts applied research for the industry. NTNU and SINTEF have had cooperating research activities related to modelling, physical implementation, and control of snake robots since 2001. Over these years, our research group has acquired a leading role within this field with numerous publications in peer-reviewed conferences and top-ranked international journals. The research activity has resulted in the development of several snake robots which have attracted much national and international attention, and has also helped establish and strengthen relations with key research communities working with snake robots in Japan, USA, and the Netherlands. Nonlinear control of mechanical systems, which includes snake robot research, has been the main research activity by the research group of the authors for several decades with excellent results.
