Available in PDF, EPUB and Kindle. Book excerpt: Legged robots have the potential to extend our reach to terrains that challenge the traversal capabilities of traditional wheeled platforms. To realize this potential, diverse legged robot designs have been proposed, and a number of these robots achieved impressive indoor and outdoor terrain mobility. However, combining mobility with energy efficiency is still a challenging task due to the inherently dissipative nature of legged locomotion. Furthermore, legged robots typically operate in regimes where the natural dynamics of the mechanical system imposes strict limitations on the capability of the actuators to regulate its motion. This is especially the case for running, during which the magnitude of the ground reaction force is several times of the body weight due to the prominent dynamic effects of the motion. ☐ Biological systems demonstrate the great potential of utilizing compliant elements in legged locomotion. During running, part of the mechanical energy is recovered by the elastic deformation of muscles and tendons and returned back to the system when it is needed. In addition, by storing muscle work slowly and releasing it rapidly, compliance alleviates the requirement for powerful actuators. Introducing compliance into legged robots, however, is not a straightforward task. Compliance might lead to high frequency oscillations or impede the free motion of the joints. In addition, due to the relatively large stiffness, the behavior of the system is largely governed by the natural dynamics of the spring-mass system. Careful analysis of the natural dynamics is necessary to fully exploit the benefits of compliant elements. ☐ With the objective to close the gap between mobility and efficiency, this thesis explores the applications of both active and passive compliant elements in the design and control of running robots. The thesis begins with reduced-order running models with massless springy legs before delving into higher-dimensional models that constitute more faithful representation of robotic systems. Although these models do not incorporate energy losses due to impacts or damping effects, they can predict important aspects of running, including ground reaction force profiles, center of mass trajectories, and the change of stance duration with respect to speed. Using time-reversal symmetries of the underlying dynamics of these reduced-order models, this thesis states analytic conclusions on the stability of periodic running gaits, which can be used to facilitate controller design. Next, a detailed model with segmented leg and inelastic impact is adopted to study the periodic bounding of quadrupedal robot HyQ. Mimicking the reduced-order models, the controller introduces active compliance into the robot. Stable periodic bounding gaits emerge as the interaction results between the robot and its environment. ☐ Inspired by the complementary benefits of passive and active compliance in energy efficiency and control authority, respectively, we propose in this thesis a novel actuation concept: the switchable parallel elastic actuator (Sw-PEA). This concept relies on adding compliance in parallel with the actuator to reduce both the energy consumption as well as the torque requirement related to running robots. In addition, a mechanical switch is used to disengage the spring when it is not needed to facilitate control of joint movement. The effectiveness of the concept is demonstrated experimentally by monopedal robot SPEAR which is actuated by a Sw-PEA. Overall, this thesis explores the application of active and passive compliant elements in the control and design of running robots, using both numerical simulations as well as experimental evaluations. The result of this thesis points out a promising direction on how to use passive compliant elements in combination with actuators for the development of running robots with both good mobility and energy efficiency.
Download or read book The Cambridge Handbook of Compliance written by Benjamin van Rooij and published by Cambridge University Press. This book was released on 2021-05-20 with total page 1559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compliance has become key to our contemporary markets, societies, and modes of governance across a variety of public and private domains. While this has stimulated a rich body of empirical and practical expertise on compliance, thus far, there has been no comprehensive understanding of what compliance is or how it influences various fields and sectors. The academic knowledge of compliance has remained siloed along different disciplinary domains, regulatory and legal spheres, and mechanisms and interventions. This handbook bridges these divides to provide the first one-stop overview of what compliance is, how we can best study it, and the core mechanisms that shape it. Written by leading experts, chapters offer perspectives from across law, regulatory studies, management science, criminology, economics, sociology, and psychology. This volume is the definitive and comprehensive account of compliance.

Download or read book Neural Networks in Robotics written by George Bekey and published by Springer Science & Business Media. This book was released on 1992-11-30 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural Networks in Robotics is the first book to present an integrated view of both the application of artificial neural networks to robot control and the neuromuscular models from which robots were created. The behavior of biological systems provides both the inspiration and the challenge for robotics. The goal is to build robots which can emulate the ability of living organisms to integrate perceptual inputs smoothly with motor responses, even in the presence of novel stimuli and changes in the environment. The ability of living systems to learn and to adapt provides the standard against which robotic systems are judged. In order to emulate these abilities, a number of investigators have attempted to create robot controllers which are modelled on known processes in the brain and musculo-skeletal system. Several of these models are described in this book. On the other hand, connectionist (artificial neural network) formulations are attractive for the computation of inverse kinematics and dynamics of robots, because they can be trained for this purpose without explicit programming. Some of the computational advantages and problems of this approach are also presented. For any serious student of robotics, Neural Networks in Robotics provides an indispensable reference to the work of major researchers in the field. Similarly, since robotics is an outstanding application area for artificial neural networks, Neural Networks in Robotics is equally important to workers in connectionism and to students for sensormonitor control in living systems.

Download or read book Radically Human written by Paul Daugherty and published by Harvard Business Press. This book was released on 2022-04-26 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technology advances are making tech more . . . human. This changes everything you thought you knew about innovation and strategy. In their groundbreaking book, Human + Machine, Accenture technology leaders Paul R. Daugherty and H. James Wilson showed how leading organizations use the power of human-machine collaboration to transform their processes and their bottom lines. Now, as new AI powered technologies like the metaverse, natural language processing, and digital twins begin to rapidly impact both life and work, those companies and other pioneers across industries are tipping the balance even more strikingly toward the human side with technology-led strategy that is reshaping the very nature of innovation. In Radically Human, Daugherty and Wilson show this profound shift, fast-forwarded by the pandemic, toward more human—and more humane—technology. Artificial intelligence is becoming less artificial and more intelligent. Instead of data-hungry approaches to AI, innovators are pursuing data-efficient approaches that enable machines to learn as humans do. Instead of replacing workers with machines, they're unleashing human expertise to create human-centered AI. In place of lumbering legacy IT systems, they're building cloud-first IT architectures able to continuously adapt to a world of billions of connected devices. And they're pursuing strategies that will take their place alongside classic, winning business formulas like disruptive innovation. These against-the-grain approaches to the basic building blocks of business—Intelligence, Data, Expertise, Architecture, and Strategy (IDEAS)—are transforming competition. Industrial giants and startups alike are drawing on this radically human IDEAS framework to create new business models, optimize post-pandemic approaches to work and talent, rebuild trust with their stakeholders, and show the way toward a sustainable future. With compelling insights and fresh examples from a variety of industries, Radically Human will forever change the way you think about, practice, and win with innovation.
Download or read book Converging Technologies for Improving Human Performance written by Mihail C. Roco and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: M. C. Roco and W.S. Bainbridge In the early decades of the 21st century, concentrated efforts can unify science based on the unity of nature, thereby advancing the combination of nanotechnology, biotechnology, information technology, and new technologies based in cognitive science. With proper attention to ethical issues and societal needs, converging in human abilities, societal technologies could achieve a tremendous improvement outcomes, the nation's productivity, and the quality of life. This is a broad, cross cutting, emerging and timely opportunity of interest to individuals, society and humanity in the long term. The phrase "convergent technologies" refers to the synergistic combination of four major "NBIC" (nano-bio-info-cogno) provinces of science and technology, each of which is currently progressing at a rapid rate: (a) nanoscience and nanotechnology; (b) biotechnology and biomedicine, including genetic engineering; (c) information technology, including advanced computing and communications; (d) cognitive science, including cognitive neuroscience. Timely and Broad Opportunity. Convergence of diverse technologies is based on material unity at the nanoscale and on technology integration from that scale.
Download or read book Human Robot Interaction written by Céline Jost and published by Springer Nature. This book was released on 2020-05-13 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the first comprehensive yet critical overview of methods used to evaluate interaction between humans and social robots. It reviews commonly used evaluation methods, and shows that they are not always suitable for this purpose. Using representative case studies, the book identifies good and bad practices for evaluating human-robot interactions and proposes new standardized processes as well as recommendations, carefully developed on the basis of intensive discussions between specialists in various HRI-related disciplines, e.g. psychology, ethology, ergonomics, sociology, ethnography, robotics, and computer science. The book is the result of a close, long-standing collaboration between the editors and the invited contributors, including, but not limited to, their inspiring discussions at the workshop on Evaluation Methods Standardization for Human-Robot Interaction (EMSHRI), which have been organized yearly since 2015. By highlighting and weighing good and bad practices in evaluation design for HRI, the book will stimulate the scientific community to search for better solutions, take advantages of interdisciplinary collaborations, and encourage the development of new standards to accommodate the growing presence of robots in the day-to-day and social lives of human beings.
Download or read book World Development Report 2020 written by World Bank and published by World Bank Publications. This book was released on 2019-11-19 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global value chains (GVCs) powered the surge of international trade after 1990 and now account for almost half of all trade. This shift enabled an unprecedented economic convergence: poor countries grew rapidly and began to catch up with richer countries. Since the 2008 global financial crisis, however, the growth of trade has been sluggish and the expansion of GVCs has stalled. Meanwhile, serious threats have emerged to the model of trade-led growth. New technologies could draw production closer to the consumer and reduce the demand for labor. And trade conflicts among large countries could lead to a retrenchment or a segmentation of GVCs. World Development Report 2020: Trading for Development in the Age of Global Value Chains examines whether there is still a path to development through GVCs and trade. It concludes that technological change is, at this stage, more a boon than a curse. GVCs can continue to boost growth, create better jobs, and reduce poverty provided that developing countries implement deeper reforms to promote GVC participation; industrial countries pursue open, predictable policies; and all countries revive multilateral cooperation.

Download or read book The System of Objects written by Jean Baudrillard and published by Verso Books. This book was released on 2020-04-07 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The System of Objects is a tour de force—a theoretical letter-in-a-bottle tossed into the ocean in 1968, which brilliantly communicates to us all the live ideas of the day. Pressing Freudian and Saussurean categories into the service of a basically Marxist perspective, The System of Objects offers a cultural critique of the commodity in consumer society. Baudrillard classifies the everyday objects of the “new technical order” as functional, nonfunctional and metafunctional. He contrasts “modern” and “traditional” functional objects, subjecting home furnishing and interior design to a celebrated semiological analysis. His treatment of nonfunctional or “marginal” objects focuses on antiques and the psychology of collecting, while the metafunctional category extends to the useless, the aberrant and even the “schizofunctional.” Finally, Baudrillard deals at length with the implications of credit and advertising for the commodification of everyday life. The System of Objects is a tour de force of the materialist semiotics of the early Baudrillard, who emerges in retrospect as something of a lightning rod for all the live ideas of the day: Bataille’s political economy of “expenditure” and Mauss’s theory of the gift; Reisman’s lonely crowd and the “technological society” of Jacques Ellul; the structuralism of Roland Barthes in The System of Fashion; Henri Lefebvre’s work on the social construction of space; and last, but not least, Guy Debord’s situationist critique of the spectacle.
