By the dawn of the new millennium, robotics has undergone a major transf- mation in scope and dimensions. This expansion has been brought about by the maturity of the ?eld and the advances in its related technologies. From a largely dominant industrial focus, robotics has been rapidly expanding into the challenges of the human world. The new generation of robots is expected to safely and dependably co-habitat with humans in homes, workplaces, and c- munities, providing support in services, entertainment, education, healthcare, manufacturing, and assistance. Beyond its impact on physical robots, the body of knowledge robotics has produced is revealing a much wider rangeof applications reaching across diverse research areas and scienti?c disciplines, such as: biomechanics, haptics, n- rosciences, virtual simulation, animation, surgery, and sensor networks among others. In return, the challenges of the new emerging areas are proving an ab- dant source of stimulation and insights for the ?eld of robotics. It is indeed at the intersection of disciplines that the most striking advances happen. The goal of the series of Springer Tracts in Advanced Robotics (STAR) is to bring, in a timely fashion, the latest advances and developments in robotics on thebasisoftheirsigni?canceandquality.Itisourhopethatthewiderdissemi- tion of research developments will stimulate more exchanges and collaborations among the research community and contribute to further advancement of this rapidly growing ?eld.

Joint flexibility from harmonic or direct drives or flexible couplings limits the performance of robots. Performance can be improved by taking into account the fast dynamics that are introduced by joint flexibility. High gain acceleration feedback from the link angles simplifies the robot dynamics, but is limited by joint flexibility. One solution is to use joint torque feedback to stabilize the fast dynamics. In light of this, drive systems that incorporate joint torque sensors are being developed. Flexible Joint Robots is the first book to consider the myriad problems and potential solutions that affect flexible joint robot design. The book covers fundamental concepts, including joint torque feedback control laws, acceleration feedback, and adaptive control laws. It presents a dynamic model of a flexible joint robot in several coordinate systems and includes an analysis of the fast dynamics.

The advent of new high-speed microprocessor technology together with the need for high-performance robots created substantial and realistic place for control theory in the field of robotics. Since the beginning of the 80's, robotics and control theory have greatly benefited from a mutual fertiliza tion. On one hand, robot models (inherently highly nonlinear) have been used as good case studies for exemplifying general concepts of analysis and design of advanced control theory; on the other hand, robot manipulator by using new control algorithms. Fur performance has been improved thermore, many interesting robotics problems, e. g. , in mobile robots, have brought new control theory research lines and given rise to the development of new controllers (time-varying and nonlinear). Robots in control are more than a simple case study. They represent a natural source of inspiration and a great pedagogical tool for research and teaching in control theory. Several advanced control algorithms have been developed for different types of robots (rigid, flexible and mobile), based either on existing control techniques, e. g. , feedback linearization and adaptive control, or on new control techniques that have been developed on purpose. Most of those results, although widely spread, are nowadays rather dispersed in different journals and conference proceedings. The purpose of this book is to collect some of the most fundamental and current results on theory of robot control in a unified framework, by editing, improving and completing previous works in the area.

The problem of the control of flexible joint robots is considered. Motion and torque control of robot joints, especially those equipped with harmonic drive (HD) transmission, is a challenging task due to the inherent nonlinear characteristics and joint flexibility of such systems. Two issues related to the control of flexible joint robots are investigated. The first is the development of a systematic scheme for selecting uncertainty bounds of robot joint nonlinearity and flexibility for control design purposes. The second is the development of motion and torque control schemes that guarantee robust performance in the presence of model uncertainties. We propose a twofold robust control design for flexible joint robots with HD: an actuator-level torque control and a link-level motion control. We utilize multivariable ${\cal H}\sb\infty$-based optimal control laws supported entirely by frequency domain measures at both levels. The proposed method provides a unified framework for achieving the desired performance requirements and for preserving robust stability in the presence of model uncertainties. Using simulation it is shown that the proposed method is more robust than conventional methods because the uncertainties due to the actuator-transmission nonlinearity are explicitly considered in the control design procedure. In the design of the actuator level torque control, we analyze nonlinear harmonic drive phenomena that have been widely observed in experiments. The focus is on incorporating into the control design process a knowledge of the mismatch between the physical system and its mathematical models. The describing function and conic-sector-bounded nonlinearity methods are used to build into the control design process the effects of mismatch between hysteresis, friction and nonlinear stiffness of HD transmission and their mathematical models. In the design of the link level motion control, a nonlinear compensator based on the computed torque technique is derived. It is shown that the closed-loop system achieves robust performance using the proposed control design technique. Using the Small Gain theorem and the Lyapunov Function method, the stability of the proposed control scheme is verified. Finally, in order to illustrate the proposed technique two control designs are presented for the IRIS-facility experimental testbed (a versatile, modular, and reconfigurable prototype robot developed at the Robotics and Automaton Laboratory of the University of Toronto) together with simulation and experimental results.

This book introduces an unified function approximation approach to the control of uncertain robot manipulators containing general uncertainties. It works for free space tracking control as well as compliant motion control. It is applicable to the rigid robot and the flexible joint robot. Even with actuator dynamics, the unified approach is still feasible. All these features make the book stand out from other existing publications.
