One of the fundamental requirements for the success of a robot task is the capability to handle interaction between manipulator and environment. The quantity that describes the state of interaction more effectively is the contact force at the manipulator's end effector. High values of contact force are generally undesirable since they may stress both the manipulator and the manipulated object; hence the need to seek for effective force control strategies. This text provides a theoretical and experimental treatment of robot interaction control. In the framework of model-based operational space control, stiffness control and impedance control are presented as the basic strategies for indirect force control. A key feature is the coverage of six-degree-of-freedom interaction tasks and manipulator kinematic redundancy. Then, direct force control strategies are presented which are obtained from motion control schemes suitably modified by the closure of an outer force regulation feedback loop. Finally, advanced force and position control strategies are presented which include passivity-based, adaptive and output feedback control schemes.All control schemes are experimentally tested on a setup consisting of a seven-joint industrial robot with open control architecture and force/torque sensor. The topic of robot force control is not treated in depth in robotics textbooks, in spite of its importance for practical manipulation tasks. This book is thus aimed at filling this gap by providing a theoretical and experimental treatment of robot force control.

Remarkably, all control schemes are experimentally tested on a setup consisting of a seven-joint industrial robot with open control architecture and force/torque sensor. The topic of robot force control is not treated in depth in robotics textbooks, in spite of its crucial importance for practical manipulation tasks. In the few books addressing this topic, the material is often limited to single-degree-of-freedom tasks. On the other hand, several results are available in the robotics literature but no dedicated monograph exists. The book is thus aimed at filling this gap by providing a theoretical and experimental treatment of robot force control.

The classic text on robot manipulators now covers visual control, motion planning and mobile robots too!Based on the successful Modelling and Control of Robot Manipulators by Sciavicco and Siciliano (Springer, 2000), Robotics provides the basic know-how on the foundations of robotics: modelling, planning and control.

This textbook explores the foundational principles of robotics, focusing on its core pillars: modeling, planning, and control. Balancing mathematical rigor and physical intuition, a coherent formalism is established and used throughout the book. At the same time, technological challenges and application-driven solutions are given appropriate consideration.With a general perspective that includes both fixed-base manipulators and mobile robots, the book presents the essential tools for understanding key topics such as kinematics, statics, trajectory planning, dynamics, and motion control. In its second part, more advanced topics are addressed, including wheeled robots, visual control, motion planning, force control, flexible robots and cooperative manipulation.To support the learning process, appendices provide essential background material on linear algebra, mechanics, differential geometry, control theory, and graph search algorithms. The practical implementation of the methodologies is emphasized throughout, with over 50 worked examples and case studies, many supported by simulations. Additionally, more than 190 end-of-chapter problems are included, with a Solutions Manual available for instructors adopting the book for their courses.Foundations of Robotics is designed for use as a textbook in both undergraduate and graduate robotics courses within engineering programs, making it an ideal resource for students and educators alike.

The book reports an extended version of the lectures given by distinguished scholars at the workshop "Fault diagnosis and fault tolerance for dynamic systems" held in conjunction with the 2002 IEEE International Symposium on Intelligent Control in Vancouver, Canada, from 27-30 October 2002. The book collects some of the most recent results in fault diagnosis and fault tolerant systems with particular emphasis on mechatronic systems. Each chapter focuses on either theoretical aspects or applications to different fields of interest in mechatronics such as industrial robotics, underwater vehicles, hydraulic systems, and flight control.
