Whole-Body Control for Multi-Contact Balancing of Humanoid Robots: Design and Experiments (Springer Tracts in Advanced Robotics #143)

by Bernd Henze

This book aims at providing algorithms for balance control of legged, torque-controlled humanoid robots. A humanoid robot normally uses the feet for locomotion. This paradigm is extended by addressing the challenge of multi-contact balancing, which allows a humanoid robot to exploit an arbitrary number of contacts for support. Using multiple contacts increases the size of the support polygon, which in turn leads to an increased robustness of the stance and to an increased kinematic workspace of the robot. Both are important features for facilitating a transition of humanoid robots from research laboratories to real-world applications, where they are confronted with multiple challenging scenarios, such as climbing stairs and ladders, traversing debris, handling heavy loads, or working in confined spaces. The distribution of forces and torques among the multiple contacts is a challenging aspect of the problem, which arises from the closed kinematic chain given by the robot and its environment.

Whole-Body Impedance Control of Wheeled Humanoid Robots

by Alexander Dietrich

Introducing mobile humanoid robots into human environments requires the systems to physically interact and execute multiple concurrent tasks. The monograph at hand presents a whole-body torque controller for dexterous and safe robotic manipulation. This control approach enables a mobile humanoid robot to simultaneously meet several control objectives with different pre-defined levels of priority, while providing the skills for compliant physical contacts with humans and the environment. After a general introduction into the topic of whole-body control, several essential reactive tasks are developed to extend the repertoire of robotic control objectives. Additionally, the classical Cartesian impedance is extended to the case of mobile robots. All of these tasks are then combined and integrated into an overall, priority-based control law. Besides the experimental validation of the approach, the formal proof of asymptotic stability for this hierarchical controller is presented. By interconnecting the whole-body controller with an artificial intelligence, the immense potential of the integrated approach for complex real-world applications is shown. Several typical household chores, such as autonomously wiping a window or sweeping the floor with a broom, are successfully performed on the mobile humanoid robot Rollin' Justin of the German Aerospace Center (DLR). The results suggest the presented controller for a large variety of fields of application such as service robotics, human-robot cooperation in industry, telepresence in medical applications, space robotics scenarios, and the operation of mobile robots in dangerous and hazardous environments.

The Whole Building Handbook: How to Design Healthy, Efficient and Sustainable Buildings

by Maria Block Varis Bokalders

The Whole Building Handbook is a compendium of all the issues and strategies that architects need to understand to design and construct sustainable buildings for a sustainable society. The authors move beyond the current definition of sustainability in architecture, which tends to focus on energy-efficiency, to include guidance for architecture that promotes social cohesion, personal health, renewable energy sources, water and waste recycling systems, permaculture, energy conservation - and crucially, buildings in relation to their place. The authors offer a holistic approach to sustainable architecture and authoritative technical advice, on: * How to design and construct healthy buildings, through choosing suitable materials, healthy service systems, and designing a healthy and comfortable indoor climate, including solutions for avoiding problems with moisture, radon and noise as well as how to facilitate cleaning and maintenance. * How to design and construct buildings that use resources efficiently, where heating and cooling needs and electricity use is minimized and water-saving technologies and garbage recycling technologies are used. * How to 'close' organic waste, sewage, heat and energy cycles. For example, how to design a sewage system that recycles nutrients. * Includes a section on adaptation of buildings to local conditions, looking at how a site must be studied with respect to nature, climate and community structure as well as human activities. The result is a comprehensive, thoroughly illustrated and carefully structured textbook and reference.

Whole Earth: The Many Lives of Stewart Brand

by John Markoff

Told by one of our greatest chroniclers of technology and society, the definitive biography of iconic serial visionary Stewart Brand, from the Merry Pranksters and the generation-defining Whole Earth Catalog to the marriage of environmental consciousness and hacker capitalism and the rise of a new planetary culture—the story behind so many other storiesStewart Brand has long been famous if you know who he is, but for many people outside the counterculture, early computing, or the environmental movement, he is perhaps best known for his famous mantra &“Stay Hungry. Stay Foolish.&” Steve Jobs&’s endorsement of these words as his code to live by is fitting; Brand has played many roles, but one of the most important is as a model for how to live. The contradictions are striking: A blond-haired WASP with a modest family inheritance, Brand went to Exeter and Stanford and was an army veteran, but in California in the 1960s he became an artist and a photographer in the thick of the LSD revolution. While tripping on acid on the roof of his building, he envisioned how valuable it would be for humans to see a photograph of the planet they shared from space, an image that in the end landed on the cover of his Whole Earth Catalog, the defining publication of the counterculture. He married a Native American woman and was committed to protecting indigenous culture, which connected to a broader environmentalist mission that has been a through line of his life. At the same time, he has outraged purists because of his pragmatic embrace of useful technologies, including nuclear power, in the fight against climate change. The famous tagline promise of his catalog was &“Access to Tools&”; with rare exceptions he rejected politics for a focus on direct power. It was no wonder, then, that he was early to the promise of the computer revolution and helped define it for the wider world. Brand's life can be hard to fit onto one screen. John Markoff, also a great chronicler of tech culture, has done something extraordinary in unfolding the rich, twisting story of Brand&’s life against its proper landscape. As Markoff makes marvelously clear, the streams of individualism, respect for science, environmentalism, and Eastern and indigenous thought that flow through Brand&’s entire life form a powerful gestalt, a California state of mind that has a hegemonic power to this day. His way of thinking embraces a true planetary consciousness that may be the best hope we humans collectively have.

Whole Energy System Dynamics: Theory, modelling and policy

by Catalina Spataru

In order to address the twenty-first-century challenges of decarbonisation, energy security and cost-effectiveness it is essential to understand whole energy systems and the interconnection and interaction between different components. An integrated language is therefore needed to assist energy policymakers and to help industrial stakeholders assess future energy systems and infrastructure and make realistic technical and economic decisions. Whole Energy System Dynamics provides an interdisciplinary approach to whole energy systems; providing insights and understanding of it in the context of challenges, opportunities and solutions at different levels and time steps. It discusses approaches across disciplinary boundaries as well as existing issues within three main themes: theory, modelling and policy, and their interlinkage with geopolitics, markets and practice.

Whole Life Costing: A New Approach

by Peter Caplehorn

Whole life costing has been a subject waiting to come of age for many years. What was previously of mainly academic interest is now becoming a key business tool in the procurement and construction of significant projects. With the advent of PPP and in particular of PFI, details of the project life need to be assessed and tied in to funding and operation plans. Many of these projects run to millions of pounds and are of high political or social importance, so the implications of the life of materials is crucial. A fundamental requirement of these procurement routes has been that the whole enterprise should be included within the bid, so that a company takes on not only the construction but also the running and maintenance of any building. Additionally as sustainability has emerged and grown in importance, so has the need for a whole life time costing approach, partly driven by governmental insistence. At the heart of sustainability is an understanding of what the specification means for the future of the building and how it will affect the environment. Whole life costing considers part of this and provides an understanding of how materials may perform and what allowances are needed at the end of their life. This book sets out the practical issues involved in the selection of materials, their performance, and the issues that need to be taken into account. The emphasis, unlike in other publications, is not to formularise or to package the issues but to leave the reader with a clear understanding and a sensible practical way of arriving at conclusions in the future.

Whole Life Costing for Sustainable Building

by Mariana Trusson

Whole life costing is now integral to building procurement, both for new buildings and major refurbishments. It is key when assessing investment scenarios for estates as well as individual buildings, and has become a tool for justifying higher capital cost items. Standard whole life costing methods combine capital cost, facilities costs, operational costs, income and disposal costs with a “single action–single benefit” approach. Costing based on this type of single attribute assessment misses out on realising value from the intricacies of the interactions buildings have with their occupants, users and the location in which they are placed. In contrast, the multi-attribute approach presented by the author of this book explains how to analyse the whole cost of a building, while also taking into account secondary and tertiary values of a variety of actions that are deemed important for the project owners and decision-making stakeholders. The process is an effective tool for presenting a good business case within the opportunities and constrains of real life. For example, it presents the interdependencies of how: Building location affects servicing strategies which impact on maintainability and control and, by extension, on occupant comfort; Material selection affects time on site, building maintainability as well as overall building quality and the environment; Building shape impacts on servicing strategies as well as operating costs. The reader will be shown how to incorporate this method of whole life valuation into standard cost models allowing for a more robust decision making process. This is done by breaking down project aims into their most basic aspects and adopting the methods of simple quantitative risk analysis, the functionality of which is based on real data. Written by an author immersed in project team collaboration to identify the interdependencies of design decisions throughout her professional life, this is the most practical guide available on the topic.

Whole System Design: An Integrated Approach to Sustainable Engineering

by Peter Stansinoupolos Michael H Smith Karlson Hargroves Cheryl Desha

Whole System Design is increasingly being seen as one of the most cost-effective ways to both increase the productivity and reduce the negative environmental impacts of an engineered system. A focus on design is critical, as the output from this stage of the project locks in most of the economic and environmental performance of the designed system throughout its life, which can span from a few years to many decades. Indeed, it is now widely acknowledged that all designers - particularly engineers, architects and industrial designers - need to be able to understand and implement a whole system design approach. This book provides a clear design methodology, based on leading efforts in the field, and is supported by worked examples that demonstrate how advances in energy, materials and water productivity can be achieved through applying an integrated approach to sustainable engineering. Chapters 1-5 outline the approach and explain how it can be implemented to enhance the established Systems Engineering framework. Chapters 6-10 demonstrate, through detailed worked examples, the application of the approach to industrial pumping systems, passenger vehicles, electronics and computer systems, temperature control of buildings, and domestic water systems. Published with The Natural Edge Project, the World Federation of Engineering Organizations, UNESCO and the Australian Government.

Whole-Wheat Bread for Human Health

by Yosef Dror Ephraim Rimon Reuben Vaida

This book examines the effect of whole-wheat bread on health, with evidence linking the consumption of whole-wheat products to a decrease in the relative risk of non-communicable diseases in comparison with products baked from refined flour. The authors focus on key areas such as milling and refining procedures, bakery products, and assessment of the present consumption of wheat products. They offer a detailed description of all available ingredients of wheat-kernel, with particular attention paid to the health benefits of wheat-kernel antioxidants and dietary fiber ingredients. Vitamins, glutathione, choline and betaine, carotenoids, sterols and stanols are covered, and the book concludes with a general overview of the effect of whole-wheat bread on colon activity and immune capacity. Methods of improving bread nutritional quality, and the potential for the upgrading of the nutritional qualities of whole-bread, are also discussed. Consumption of whole-wheat in Western societies, however, has either not increased or increased very slightly. The authors intend for this book to highlight the health benefits of whole-wheat bread and the factors that contribute to these benefits.
