Available in PDF, EPUB and Kindle. Book excerpt: This work explores regulation of forward speed, step length, and slope walking for the passive-dynamic class of bipedal robots. Previously, an energy-shaping control for regulating forward speed has appeared in the literature; here we show that control to be a special case of a more general time-scaling control that allows for speed transitions in arbitrary time. As prior work has focused on potential energy shaping for fully actuated bipeds, we study in detail the shaping of kinetic energy for bipedal robots, giving special treatment to issues of underactuation. Drawing inspiration from features of human walking, an underactuated kinetic-shaping control is presented that provides efficient regulation of walking speed while adjusting step length. Previous results on energetic symmetries of bipedal walking are also extended, resulting in a control that allows regulation of speed and step length while walking on any slope. Finally we formalize the optimal gait regulation problem and propose a dynamic programming solution seeded with passive-dynamic limit cycles. Observations of the optimal solutions generated by this method reveal further similarities between passive dynamic walking and human locomotion and give insight into the structure of minimum-effort controls for walking.

Available in PDF, EPUB and Kindle. Book excerpt: Here for the first time in one book is a comprehensive and systematic approach to the dynamic modeling and control of biped locomotion robots. A survey is included of various approaches to the control of biped robots, and a new approach to the control of biped systems based on a complete dynamic model is presented in detail. The stability of complete biped system is presented for the first time as a highly nonlinear dynamic system. Also included is new software for the synthesis of a dynamically stable walk for arbitrary biped systems, presented here for the first time. A survey of various realizations of biped systems and numerous numerical examples are given. The reader is given a deep insight into the entire area of biped locomotion. The book covers all relevant approaches to the subject and gives the most complete account to date of dynamic modeling, control and realizations of biped systems.

Download or read book Modeling Simulation and Optimization of Bipedal Walking written by Katja Mombaur and published by Springer Science & Business Media. This book was released on 2013-02-28 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The model-based investigation of motions of anthropomorphic systems is an important interdisciplinary research topic involving specialists from many fields such as Robotics, Biomechanics, Physiology, Orthopedics, Psychology, Neurosciences, Sports, Computer Graphics and Applied Mathematics. This book presents a study of basic locomotion forms such as walking and running is of particular interest due to the high demand on dynamic coordination, actuator efficiency and balance control. Mathematical models and numerical simulation and optimization techniques are explained, in combination with experimental data, which can help to better understand the basic underlying mechanisms of these motions and to improve them. Example topics treated in this book are Modeling techniques for anthropomorphic bipedal walking systems Optimized walking motions for different objective functions Identification of objective functions from measurements Simulation and optimization approaches for humanoid robots Biologically inspired control algorithms for bipedal walking Generation and deformation of natural walking in computer graphics Imitation of human motions on humanoids Emotional body language during walking Simulation of biologically inspired actuators for bipedal walking machines Modeling and simulation techniques for the development of prostheses Functional electrical stimulation of walking.

Download or read book Adaptability of Human Gait written by A.E. Patla and published by Elsevier. This book was released on 1991-03-25 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large number of volumes have been produced summarizing the work on generation and control of rhythmic movements, in particular locomotion. Unfortunately most of them focus on locomotor studies done on animals. This edited volume redresses that imbalance by focusing completely on human locomotor behaviour. The very nature of the problem has both necessitated and attracted researchers from a wide variety of disciplines ranging from psychology, neurophysiology, kinesiology, engineering, medicine to computer science. The different and unique perspectives they bring to this problem provide a comprehensive picture of the current state of knowledge on the generation and regulation of human locomotor behaviour. A common unifying theme of this volume is studying the adaptability of human gait to obtain insights into the control of locomotion. The intentional focus on "adaptability" is meant to draw attention to the importance of understanding the generation and regulation of "skilled locomotor behaviour" rather than just the generation of basic locomotor patterns which has been the major focus of animal studies. The synthesis chapter at the end of the volume examines how the questions posed, the technology, and the experimental and theoretical paradigms have evolved over the years, and what the future has in store for this important research domain.

Book excerpt: This comprehensively updated and expanded revision of the successful second edition continues to provide detailed coverage of the ever-growing range of research topics in vision. In Part I, the treatment of visual physiology has been extensively revised with an updated account of retinal processing, a new section explaining the principles of spatial and temporal filtering which underlie discussions in later chapters, and an up-to-date account of the primate visual pathway. Part II contains four largely new chapters which cover recent psychophysical evidence and computational model of early vision: edge detection, perceptual grouping, depth perception, and motion perception. The models discussed are extensively integrated with physiological evidence. All other chapters in Parts II, III, and IV have also been thoroughly updated.

Download or read book Visual Perception and Action in Sport written by Keith Davids and published by Taylor & Francis. This book was released on 2005-08-10 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Athletes are dependent upon a constant supply of accurate and reliable information from the environment whilst performing complex movements. Visual Perception and Action in Sport examines the information which is perceived by the human visual system and the way it is utilised to support actions in sport. It focuses attention on the rich diversity of sport-related studies drawn together from a number of theoretical approaches. Divided into three sections, this book covers: * indirect theories of perception and action * direct theories of perception and action * skill acquisition in the sports context. Each of the sections features learning objectives, summary, and study questions to help facilitate student learning. Throughout the text, the integration of theoretical knowledge and practical expertise is emphasised. All three authors are specialists have expertise in the teaching and researching of motor learning and control in sport.

Download or read book Time to Contact written by Heiko Hecht and published by Elsevier. This book was released on 2004-05-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-to-contact is the visual information that observers use in fundamental tasks such as landing an airplane or hitting a ball. Time-to-contact has been a hot topic in perception and action for many years and although many articles have been published on this topic, a comprehensive overview or assessment of the theory does not yet exist. This book fills an important gap and will have appeal to the perception and action community. The book is divided into four sections. Section one covers the foundation of time-to-contact, Section two covers different behavioral approaches to time-to-contact estimation, Section three focuses on time-to-contact as perception and strategy, and Section four covers time-to-contact and action regulation.
