This 3-volume handbook brings together contributions by the world ́s leading specialists that reflect the broad spectrum of modern palaeoanthropology, thus presenting an indispensable resource for professionals and students alike. Vol. 1 reviews principles, methods, and approaches, recounting recent advances and state-of-the-art knowledge in phylogenetic analysis, palaeoecology and evolutionary theory and philosophy. Vol. 2 examines primate origins, evolution, behaviour, and adaptive variety, emphasizing integration of fossil data with contemporary knowledge of the behaviour and ecology of living primates in natural environments. Vol. 3 deals with fossil and molecular evidence for the evolution of Homo sapiens and its fossil relatives.
Dynamic modeling is the fundamental building block for mechanism analysis, design, control and performance evaluation. One class of mechanism, legged machines, have multiple closed-chains established through intermittent ground contacts. Further, walking on natural terrain introduces nonlinear system compliance in the forms of foot sinkage and slippage. Closed-chains constrain the possible motions of a mechanism while compliances affect the redistribution of forces throughout the system. A General Model of Legged Locomotion on Natural Terrain develops a dynamic mechanism model that characterizes indeterminate interactions of a closed-chain robot with its environment. The approach is applicable to any closed-chain mechanism with sufficient contact compliance, although legged locomotion on natural terrain is chosen to illustrate the methodology. The modeling and solution procedures are general to all walking machine configurations, including bipeds, quadrupeds, beam-walkers and hopping machines. This work develops a functional model of legged locomotion that incorporates, for the first time, non-conservative foot-soil interactions in a nonlinear dynamic formulation. The model was applied to a prototype walking machine, and simulations generated significant insights into walking machine performance on natural terrain. The simulations are original and essential contributions to the design, evaluation and control of these complex robot systems. While posed in the context of walking machines, the approach has wider applicability to rolling locomotors, cooperating manipulators, multi-fingered hands, and prehensile agents.
On the Gait of Animals Aristotle Other works by the renowned classical scholar, translator, and literary critic Francis Fergusson include "The Idea of a Theater: A Study of Ten Plays," "Sallies of the Mind: Essays," "Trope and Allegory: Themes Common to Dante and Shakespeare," and "Dante's Drama of the Mind: A Modern Reading of the "Purgatorio. Translator and scholar S. H. Butcher served as editor for the Dover Thift Edition of the "Poetics," as well as for the "Orationes, Volume 1" by Demosthenes. Butcher is also the author of "Aristotle's Theory of Poetry and Fine Art," We are delighted to publish this classic book as part of our extensive Classic Library collection. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. The aim of our publishing program is to facilitate rapid access to this vast reservoir of literature, and our view is that this is a significant literary work, which deserves to be brought back into print after many decades. The contents of the vast majority of titles in the Classic Library have been scanned from the original works. To ensure a high quality product, each title has been meticulously hand curated by our staff. Our philosophy has been guided by a desire to provide the reader with a book that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic work, and that for you it becomes an enriching experience.
The study of primate locomotion is a unique discipline that by its nature is interdis ciplinary, drawing on and integrating research from ethology, ecology, comparative anat omy, physiology, biomechanics, paleontology, etc. When combined and focused on particular problems this diversity of approaches permits unparalleled insight into critical aspects of our evolutionary past and into a major component of the behavioral repertoire of all animals. Unfortunately, because of the structure of academia, integration of these different approaches is a rare phenomenon. For instance, papers on primate behavior tend to be published in separate specialist journals and read by subgroups of anthropologists and zoologists, thus precluding critical syntheses. In the spring of 1995 we overcame this compartmentalization by organizing a con ference that brought together experts with many different perspectives on primate locomo tion to address the current state of the field and to consider where we go from here. The conference, Primate Locomotion-1995, took place thirty years after the pioneering confer ence on the same topic that was convened by the late Warren G. Kinzey at Davis in 1965.
Walking machines have advantages over traditional vehicles, and have already accomplished tasks that wheeled or tracked robots cannot handle. Nevertheless, their use in industry and services is currently limited in scope. This book brings together methods and techniques that have been developed to deal with obstacles to wider acceptance of legged robots. Part I provides an historical overview. Part II concentrates on control techniques, as applied to Four-legged robots.
Gain a thorough understanding of animation and character rigging using Autodesk 3ds Max to create realistic character animations. This book is split into three modules that are subsequently divided into chapters. The first module is the foundation module: in this module you’ll cover, among other topics, the 12 cardinal principles of animation with reference to classic real-world examples and famous movies/animation shots. Using these, the further chapters explore using key frames and graph editors to obtain fluid motion in your animations. Practical examples are used to better explain which feature suits a particular scenario. The second module, called the backbone module, introduces you to deformation tools and their use for character animation. Further chapters cover driven animations, constraints posed by bones, bipeds, and the CAT tools available in 3ds Max 2019. The final module, the lifeline module, encourages you to bring your character to life by applying principles learnt in the previous modules. Here you will be guided on how to retarget animations from one character to other characters or rigs. On completing Character Rigging and Advance Animation, you will be able to create character rigs for bipeds and quadrupeds with ease, animating them with life-like motion. What You Will Learn Understand the 12 principles of animationSet up an animation-ready character rig from scratchMaster the deformation tools available for animation Who This Book Is For Readers who are familiar with 3ds Max at a basic level and are looking at getting into character rigging and animation.
