Available in PDF, EPUB and Kindle. Book excerpt: LES ROBOTS BIPEDES CONSTITUENT UNE CLASSE PARTICULIEREMENT INTERESSANTE DE ROBOTS MOBILES, EN RAISON DE LEUR CAPACITE D'ADAPTATION A DES TERRAINS OU DES SOLS VARIES. CEPENDANT, LA SYNTHESE ET LE CONTROLE DE LA MARCHE DES ROBOTS BIPEDES POSENT DES PROBLEMES TRES COMPLIQUES TELS QUE LE CONTROLE DE LA STABILITE STATIQUE ET DYNAMIQUE DU ROBOT PENDANT LA MARCHE. CETTE THESE S'INTERESSE A LA MARCHE STATIQUEMENT STABLE D'UN MODELE PLAN DE ROBOT BIPEDE A 7 SEGMENTS. CE MODE DE MARCHE EST CARACTERISE PAR LE MAINTIEN DE LA PROJECTION VERTICALE DU CENTRE DE MASSE (CM) TOTAL DU CORPS A L'INTERIEUR DE LA SURFACE DE SUSTENTATION. LA MARCHE STATIQUEMENT STABLE PEUT ETRE AINSI ASSIMILEE A UNE SUCCESSION DE POSTURES STABLES. GENERALEMENT CETTE ALLURE DE MARCHE S'EFFECTUE A FAIBLE VITESSE AFIN DE REDUIRE LES EFFETS DE L'INERTIE. LA MARCHE HUMAINE EST, EN GENERAL, UNE MARCHE DYNAMIQUE OU L'ETRE HUMAIN PROFITE DE L'INERTIE ET DE LA FORCE DE GRAVITE POUR EFFECTUER DES MOUVEMENTS BALISTIQUES. TOUTEFOIS, ON OBSERVE LA MARCHE STATIQUEMENT STABLE PENDANT LA MARCHE SUR UNE SURFACE ACCIDENTEE OU PENDANT LA MONTEE D'ESCALIERS. LE CALCUL DU CM EST PRESENTE A TRAVERS UNE RELATION D'EQUIVALENCE CINEMATIQUE COMPLETE ENTRE LES COORDONNEES TRIDIMENSIONNELLES DU CM D'UNE STRUCTURE ARBORESCENTE QUELCONQUE ET LA POSITION DU POINT TERMINAL D'UNE CHAINE SIMPLE DONT LES PARAMETRES GEOMETRIQUES DEPENDENT DE LA DISTRIBUTION MASSIQUE DU SYSTEME ORIGINAL ET DONT LES VARIABLES DE CONFIGURATION SONT UNE FONCTION INVARIANTE SIMPLE DES VARIABLES DE LA CHAINE ORIGINALE. LES SCHEMAS DE COMMANDE SONT BASES SUR L'APPROCHE DU CONTROLE PAR FONCTION DE TACHE, OU LE PROBLEME DE CONTROLE EST ASSIMILE A UN PROBLEME DE MINIMISATION D'UNE FONCTION DE COUT. L'OBJECTIF GLOBAL DE LA COMMANDE EST DECOMPOSE EN TROIS SOUS-TACHES DONT LA REALISATION SE FAIT PAR UN ORDRE DE PRIORITE DEFINIE PAR LA FONCTION DE TACHE GLOBALE. CES APPROCHES SONT APPLIQUEES POUR LA MARCHE SUR UNE SURFACE PLANE, LA MONTEE ET LA DESCENTE D'ESCALIERS.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse traite le problème de la commande de la marche dynamique des robots bipèdes sous-actionnés. Deux nouvelles approches de commande sont proposées. La première est une commande prédictive non linéaire de faible dimension. Elle consiste à trouver un retour d'état partiellement linéarisant et des trajectoires de référence sur les coordonnées linearisées. Ces trajectoires sont paramétrées par un scalaire calculé par optimisation afin de stabiliser la dynamique des zéros. L'analyse de la stabilité en boucle fermée est effectuée en utilisant un outil graphique basé sur la section de Poincaré. La deuxième approche de commande fait partie des approches dites de Lyapunov. Elle est basée sur des lois de commande non linéaires inspirées des commandes dites hybrides position/force. Principalement, elle consiste à commander le robot bipède dans les différentes phases du cycle de marche, tout en assurant une stabilité du système sur le cycle complet de marché.

Book excerpt: LE TRAVAIL QUE NOUS PRESENTONS APPORTE UNE CONTRIBUTION NOUVELLE DANS LE DOMAINE DES ROBOTS MARCHEURS. OUTRE LA BIBLIOGRAPHIE EXHAUSTIVE, REALISEE CONCERNANT CE TYPE DE ROBOTS ET EN PARTICULIER LES BIPEDES, NOUS AVONS REALISE LES MODELISATIONS GEOMETRIQUES, CINEMATIQUE ET DYNAMIQUE D'UN ROBOT MARCHEUR BIPEDE A 5 CORPS DANS L'ESPACE QUI CONSTITUE UNE NOUVELLE ETAPE DANS LA COMPREHENSION DE LA MARCHE. LA MODELISATION DYNAMIQUE DE CE BIPEDE, S'APPUIE SUR LE FORMALISME DE NEWTON-EULER DANS LEQUEL, GRACE A UN PROCEDE MATHEMATIQUE, EST REALISE L'ELIMINATION DES EFFORTS INTERIEURS. POUR DECRIRE LA CHAINE CINEMATIQUE DU BIPEDE, ON UTILISE LES COORDONNEES CARTESIENNES INERTIELLES DU CENTRE DE MASSE, LES ANGLES D'EULER INERTIELS DE CHAQUE SOLIDE ET LES EQUATIONS DE LIAISONS ENTRE LES SOLIDES. ON DISTINGUE PARMI CES LIAISONS CELLES QUI SONT HOLONOMES ET CELLES QUI SONT NON HOLONOMES. NOUS AVONS DEVELOPPE DEUX LOGICIELS DE CALCUL SYMBOLIQUE, L'UN PERMETTANT L'OBTENTION AUTOMATIQUE DES EQUATIONS DE LIAISONS HOLONOMES POUR UNE CHAINE CINEMATIQUE ARTICULEE GENERALE ET EN PARTICULIER POUR LE BIPEDE, ET L'AUTRE PERMETTANT LE CALCUL AUTOMATIQUE D'UNE PARTIE DES EQUATIONS DYNAMIQUES. ENFIN, AUX MODELISATIONS GEOMETRIQUES ET CINEMATIQUES OBTENUES, EST ACCOMPAGNEE UNE SELECTION DE TRAJECTOIRES PLAUSIBLES DU BIPEDE SELON UN CRITERE DIT DANS LA LITTERATURE CRITERE DU ZMP, ET UNE ANIMATION DE CERTAINS MOUVEMENTS DE LA MARCHE

L'OBJECTIF CONSISTE A DEFINIR UNE LOCOMOTION PERMETTANT A UN ROBOT A PATTES DE MARCHER AUSSI VITE QUE POSSIBLE SUR TERRAIN PLAT, TOUT EN MAINTENANT TROIS PATTES AU SOL. L'ETUDE EST BASEE SUR LES ALLURES BIEN CONNUES DE TYPE CRAWL, UTILISEES PAR BEAUCOUP DE MAMMIFERES LORSQU'ILS GARDENT TROIS PATTES EN CONTACT AVEC LE SOL. LE CRAWL EN MARCHE AVANT EST AMELIORE GRACE A LA SUPERPOSITION D'UN MOUVEMENT OSCILLATOIRE LATERAL DU CENTRE DE MASSE DE LA PLATE-FORME. CECI PERMET DE GARANTIR L'EQUILIBRE QUAND L'ALLURE SE RAPPROCHE DE LA LIMITE DU CRAWL. AU-DELA DE CETTE LIMITE, L'ALLURE EST CARACTERISEE PAR DES PHASES A DEUX PATTES AU SOL ET CONVERGE VERS LE TROT. DES VIRAGES ET DES ROTATIONS SUR PLACE SONT AUSSI DEFINIS SUIVANT LE MEME PRINCIPE QUE LE CRAWL EN MARCHE AVANT. DE PLUS, LES TRANSITIONS ENTRE LES DIFFERENTS TYPES DE MARCHE - MARCHE AVANT, ARRIERE, VIRAGES ET ROTATIONS - SONT PARTICULIEREMENT DETAILLEES.

Available in PDF, EPUB and Kindle. Book excerpt: The essays in this edited volume, written in English and French, tackle the intriguing problems of fear and safety by analysing their various meanings and manifestations in literature and other narrative media. The articles bring forth new, cross-cultural interpretations on fear and safety through examining what kinds of genre-specific means of world-making narratives use to express these two affectivities. The articles also show how important it is to study these themes in order to understand challenges in times of global threats, such as the climate crisis. The main themes of the book are approached from various theoretical perspectives as related to their literary and cultural representations. Recent trends in research, such as affect and risk theory, serve as the basis for the discussion. The articles in the volume also draw from disciplines such as gender studies and trauma studies to examine the threats posed by collective fears and aggression on individuals' lives and propose ways of coping with fear. These themes are addressed also in articles analysing new adaptations of old myths that retell stories of the past. Many of the articles in the volume discuss apocalyptic and dystopian narratives that currently permeate the entire cultural landscape. Dystopian narratives do not only deal with future threats, such as totalitarianism, technocracy, or environmental disasters, but also suggest alternative ways of being and new hopes in the form of political resistance.

Available in PDF, EPUB and Kindle. Book excerpt: This is one of the first systematic attempts to bring language within the neo-Darwinian framework of modern evolutionary theory, without abandoning the vast gains in phonology and syntax achieved by formal linguistics over the past forty years. The contributors, linguists, psychologists, and paleoanthropologists, address such questions as: what is language as a category of behavior; is it an instrument of thought or of communication; what do individuals know when they know a language; what cognitive, perceptual, and motor capacities must they have to speak, hear, and understand a language? For the past two centuries, scientists have tended to see language function as largely concerned with the exchange of practical information. By contrast, this volume takes as its starting point the view of human intelligence as social, and of language as a device for forming alliances, in exploring the origins of the sound patterns and formal structures that characterize language.

Book excerpt: The papers in this volume discuss the current status of the cognitive/neuroscience synthesis in research on vision, whether and how linguistics and neuroscience can be integrated, and how integrative brain mechanisms can be studied through the use of noninvasive brain-imaging techniques. Recent attempts to unify linguistic theory and brain science have grown out of recognition that a proper understanding of language in the brain must reflect the steady advances in linguistic theory of the last forty years. The first Mind Articulation Project Symposium addressed two main questions: How can the understanding of language from linguistic research be transformed through the study of the biological basis of language? And how can our understanding of the brain be transformed through this same research? The best model so far of such mutual constraint is research on vision. Indeed, the two long-term goals of the Project are to make linguistics and brain science mutually constraining in the way that has been attempted in the study of the visual system and to formulate a cognitive theory that more strongly constrains visual neuroscience. The papers in this volume discuss the current status of the cognitive/neuroscience synthesis in research on vision, whether and how linguistics and neuroscience can be integrated, and how integrative brain mechanisms can be studied through the use of noninvasive brain-imaging techniques.

Book excerpt: The book includes all the background material required to understand the principles underlying intelligence, as well as enough detailed information on intelligent robotics and simulated agents so readers can begin experiments and projects on their own. By the mid-1980s researchers from artificial intelligence, computer science, brain and cognitive science, and psychology realized that the idea of computers as intelligent machines was inappropriate. The brain does not run "programs"; it does something entirely different. But what? Evolutionary theory says that the brain has evolved not to do mathematical proofs but to control our behavior, to ensure our survival. Researchers now agree that intelligence always manifests itself in behavior—thus it is behavior that we must understand. An exciting new field has grown around the study of behavior-based intelligence, also known as embodied cognitive science, "new AI," and "behavior-based AI." This book provides a systematic introduction to this new way of thinking. After discussing concepts and approaches such as subsumption architecture, Braitenberg vehicles, evolutionary robotics, artificial life, self-organization, and learning, the authors derive a set of principles and a coherent framework for the study of naturally and artificially intelligent systems, or autonomous agents. This framework is based on a synthetic methodology whose goal is understanding by designing and building. The book includes all the background material required to understand the principles underlying intelligence, as well as enough detailed information on intelligent robotics and simulated agents so readers can begin experiments and projects on their own. The reader is guided through a series of case studies that illustrate the design principles of embodied cognitive science.

Available in PDF, EPUB and Kindle. Book excerpt: Speech is the principal supporting medium of language. In this book Pierre-Yves Oudeyer considers how spoken language first emerged. He presents an original and integrated view of the interactions between self-organization and natural selection, reformulates questions about the origins ofspeech, and puts forward what at first sight appears to be a startling proposal - that speech can be spontaneously generated by the coupling of evolutionarily simple neural structures connecting perception and production. He explores this hypothesis by constructing a computational system to modelthe effects of linking auditory and vocal motor neural nets. He shows that a population of agents which used holistic and unarticulated vocalizations at the outset are inexorably led to a state in which their vocalizations have become discrete, combinatorial, and categorized in the same way by allgroup members. Furthermore, the simple syntactic rules that have emerged to regulate the combinations of sounds exhibit the fundamental properties of modern human speech systems.This original and fascinating account will interest all those interested in the evolution of speech.
