Book Description
CETTE THESE PRESENTE L'ETUDE DE LA MODELISATION DES INTERACTIONS QUI SURVIENNENT LORSQUE PLUSIEURS ROBOTS MOBILES, EQUIPES DE SENSEURS VISUELS, PARTAGENT UN MEME ENVIRONNEMENT. DANS UN PREMIER TEMPS, LA MODELISATION DES CAPACITES MOTRICES ET SENSORIELLES D'UN ROBOT MOBILE EST ENVISAGEE. LE CONCEPT DE CARTE DYNAMIQUE EST AINSI INTRODUIT POUR REPRESENTER DE FACON GEOMETRIQUE LA MOBILITE DU ROBOT DANS SON ENVIRONNEMENT. CE CONCEPT EST BASE SUR LA THEORIE DES REGIONS ATTEIGNABLES D'UN SYSTEME DYNAMIQUE. LES METHODES DE CONSTRUCTION DES CARTES DYNAMIQUES DE PLUSIEURS TYPES DE ROBOT MOBILE SONT DECRITES, AINSI QU'UN ALGORITHME D'APPRENTISSAGE DE LA CARTE D'UN ROBOT PAR LUI-MEME. LA RELATION INTIME EXISTANT ENTRE LA CAMERA DU ROBOT ET SES CAPACITES DE DEPLACEMENT EST EGALEMENT EXPLOREE AU TRAVERS DU CONCEPT DE CARTE DYNAMIQUE. DANS UN DEUXIEME TEMPS, LE CONCEPT DE CARTE DYNAMIQUE EST UTILISE POUR GENERER UNE REPRESENTATION DES INTERACTIONS ENTRE LES ROBOTS MOBILES. AINSI, A PARTIR DES CONDITIONS D'ENVIRONNEMENTALES ET DES POSITIONS RELATIVES DES ROBOTS RECUPEREES PAR LE SENSEUR DU ROBOT, LA CARTE DU ROBOT APPRISE ET LES CARTES DYNAMIQUES DES AUTRES ROBOTS ESTIMEES SONT COMBINEES. CETTE COMBINAISON PERMET DE FAIRE APPARAITRE LA DISTRIBUTION DE L'ESPACE ATTEIGNABLE DU ROBOT EN FONCTION NON SEULEMENT DE SES CAPACITES MAIS EGALEMENT DE CELLES DES AUTRES ROBOTS DANS LE CADRE D'UNE TACHE A ACCOMPLIR EN COOPERATION OU EN COMPETITION. CETTE REPRESENTATION EST UTILISEE PAR LA SUITE POUR PERMETTRE LA PLANIFICATION D'UNE TRAJECTOIRE D'EVASION POUR UN ROBOT POURSUIVI ET PRESENTE. LES ECHECS ET LES REUSSITES D'UN SYSTEME D'APPRENTISSAGE D'UNE STRATEGIE DE POURSUITE PAR RENFORCEMENT ONT PERMIS DE PROUVER L'UTILISTE DE LA CARTE DYNAMIQUE COMME UN OUTIL D'ANALYSE DES INTERACTIONS ENTRE ROBOTS. UN BANC D'ESSAI EXPERIMENTAL BASE SUR DES ROBOTS RADIOGUIDES A ETE DEVELOPPE AFIN DE METTRE EN PRATIQUE DANS LE FUTUR LES CONCEPTS DECRITS DANS LE CADRE DE CETTE THESE. LES VEHICULES UTILISES NE POSSEDANT PAS D'ODOMETRIE INTERNE, LA CONCEPTION ET LA REALISATION D'UN SYSTEME D'ODOMETRIE SIMULEE A ETE NECESSAIRE

Book Description
Many robotics researchers consider high-level vision algorithms (computational) too expensive for use in robot guidance. This book introduces the reader to an alternative approach to perception for autonomous, mobile robots. It explores how to apply methods of high-level computer vision and fuzzy logic to the guidance and control of the mobile robot. The book introduces a knowledge-based approach to vision modeling for robot guidance, where advantage is taken of constraints of the robot's physical structure, the tasks it performs, and the environments it works in. This facilitates high-level computer vision algorithms such as object recognition at a speed that is sufficient for real-time navigation. The texts presents algorithms that exploit these constraints at all levels of vision, from image processing to model construction and matching, as well as shape recovery. These algorithms are demonstrated in the navigation of a wheeled mobile robot.

Book Description
This monograph introduces novel methods for the control and navigation of mobile robots using multiple-1-d-view models obtained from omni-directional cameras. This approach overcomes field-of-view and robustness limitations, simultaneously enhancing accuracy and simplifying application on real platforms. The authors also address coordinated motion tasks for multiple robots, exploring different system architectures, particularly the use of multiple aerial cameras in driving robot formations on the ground. Again, this has benefits of simplicity, scalability and flexibility. Coverage includes details of: a method for visual robot homing based on a memory of omni-directional images; a novel vision-based pose stabilization methodology for non-holonomic ground robots based on sinusoidal-varying control inputs; an algorithm to recover a generic motion between two 1-d views and which does not require a third view; a novel multi-robot setup where multiple camera-carrying unmanned aerial vehicles are used to observe and control a formation of ground mobile robots; and three coordinate-free methods for decentralized mobile robot formation stabilization. The performance of the different methods is evaluated both in simulation and experimentally with real robotic platforms and vision sensors. Control of Multiple Robots Using Vision Sensors will serve both academic researchers studying visual control of single and multiple robots and robotics engineers seeking to design control systems based on visual sensors.

Book Description
This book achieves a goal that was set 25 years ago when the HAM theory of human memory was published. This theory reflected one of a number of then-current efforts to create a theory of human cognition that met the twin goals of precision and complexity. Up until then the standard for precision had been the mathematical theories of the 1950s and 1960s. These theories took the form of precise models of specific experiments along with some informal, verbally-stated understanding of how they could be extended to new experiments. They seemed to fall far short of capturing the breadth and power of human cognition that was being demonstrated by the new experimental work in human cognition. The next 10 years saw two major efforts to address the problems of scope. In 1976, the ACT theory was first described and included a production rule system of procedural memory to complement HAM's declarative memory. This provided a computationally adequate system which was indeed capable of accounting for all sorts of cognition. In 1993, a new version of ACT--ACT-R--was published. This was an effort to summarize the theoretical progress made on skill acquisition in the intervening 10 years and to tune the subsymbolic level of ACT-R with the insights of the rational analysis of cognition. Although the appearance of generally-available, full-function code set off a series of events which was hardly planned, it resulted in this book. The catalyst for this was the emergence of a user community. Lebiere insisted that assembling a critical mass of users was essential to the ultimate success of the theory and that a physical gathering was the only way to achieve that goal. This resulted in the First Annual ACT-R Summer School and Workshop, held in 1994. In writing the book, the authors became seized by an aspiration that went beyond just describing the theory correctly. They decided to try to display what the theory could do by collecting together and describing some of its in-house applications. This book reflects decades of work in ACT-R accumulated by many researchers. The chapters are authored by the people that did that particular work. No doubt the reader will be impressed by the scope of the research and the quality of the individual work. Less apparent, but no less important, was the effort that everyone put into achieving the overall consistency and technical integrity of the book. This is the first work in cognitive science to precisely model such a wide range of phenomena with a single theory.
