Cette thèse propose et analyse un nouveau robot parallèle cinématiquement redondant (KRP) avec tous les actionneurs situés à la base. La structure de base du robot provient de travaux antérieurs, c'est-à-dire que trois jambes avec 3 degrés de liberté (ddls) chacune sont attachées à la plate-forme mobile par trois liaisons redondantes, ce qui donne un robot KRP avec (6+3) degrés de liberté. Cette thèse se concentre sur quatre thèmes. Tout d'abord, un nouveau robot parallèle à 3 ddls utilisé comme jambe du robot KRP est proposé, et tous les actionneurs sont situés à la base afin de réduire l'inertie des parties mobiles. De plus, les actionneurs sont placés près les uns des autres pour minimiser l'encombrement et produire un espace de travail relativement grand. Les problèmes cinématiques tels que la modélisation cinématique, le problème inverse/direct, l'analyse des singularités et l'espace de travail sont analysés en détail. En outre, pour simplifier l'analyse de l'espace de travail et agrandir l'espace de travail, une conception améliorée du robot à 3 ddls est proposée. L'établissement de modèles dynamiques pour les robots parallèles est un défi en raison des relations complexes entre les vitesses et les forces induites par leur structure en boucle fermée. Cette thèse propose plusieurs méthodes de modélisation simplifiées pour les robots parallèles. Le premier type est dérivé de l'approche lagrangienne et l'idée centrale est de réduire la complexité des expressions représentant l'énergie pour le robot. Par conséquent, ces méthodes ont une bonne généralité et sont disponibles pour divers robots parallèles. Cependant, pour certains robots parallèles (par exemple, le robot à 3 ddls proposé), même en utilisant la méthode simplifiée, les calculs d'énergie sont légèrement complexes. Compte tenu de cela, une autre méthode de modélisation simplifiée basée sur l'approche de Newton-Euler est proposée et analysée. Étant donné que le nouveau robot KRP a une structure similaire à celle des robots KRP précédents, la plupart des méthodes analysées dans les travaux précédents peuvent être directement utilisées. Par conséquent, cette thèse ne résout que brièvement le problème inverse/direct, explique la singularité du point de vue de la force, donne le modèle dynamique et montre la structure et le modèle CAO du prototype du nouveau robot KRP. Enfin, cette thèse propose une méthode générale de contrôle de préhension par laquelle le robot KRP peut faire fonctionner à distance une pince pour générer les forces de préhension requises tout en déplaçant la plate-forme, toutes les actions étant pilotées par les mêmes actionneurs. Le modèle de contrôle de préhension se compose d'un modèle de contrôle du mouvement des jambes et d'un modèle de contrôle de la force des jambes, où la force de préhension peut être contrôlée indépendamment. En conséquence, le modèle de contrôle en force utilise un contrôleur en boucle ouverte, simple à mettre en œuvre et efficace.

Parallel structures are more effective than serial ones for industrial automation applications that require high precision and stiffness, or a high load capacity relative to robot weight. Although many industrial applications have adopted parallel structures for their design, few textbooks introduce the analysis of such robots in terms of dynamics and control. Filling this gap, Parallel Robots: Mechanics and Control presents a systematic approach to analyze the kinematics, dynamics, and control of parallel robots. It brings together analysis and design tools for engineers and researchers who want to design and implement parallel structures in industry. Covers Kinematics, Dynamics, and Control in One Volume The book begins with the representation of motion of robots and the kinematic analysis of parallel manipulators. Moving beyond static positioning, it then examines a systematic approach to performing Jacobian analysis. A special feature of the book is its detailed coverage of the dynamics and control of parallel manipulators. The text examines dynamic analysis using the Newton-Euler method, the principle of virtual work, and the Lagrange formulations. Finally, the book elaborates on the control of parallel robots, considering both motion and force control. It introduces various model-free and model-based controllers and develops robust and adaptive control schemes. It also addresses redundancy resolution schemes in detail. Analysis and Design Tools to Help You Create Parallel Robots In each chapter, the author revisits the same case studies to show how the techniques may be applied. The case studies include a planar cable-driven parallel robot, part of a promising new generation of parallel structures that will allow for larger workspaces. The MATLAB® code used for analysis and simulation is available online. Combining the analysis of kinematics and dynamics with methods of designing controllers, this text offers a holistic introduction for anyone interested in designing and implementing parallel robots.

This book provides an essential overview of the authors’ work in the field of cable-suspended parallel robots, focusing on innovative design, mechanics, control, development and applications. It presents and analyzes several typical mechanical architectures of cable-suspended parallel robots in practical applications, including the feed cable-suspended structure for super antennae, hybrid-driven-based cable-suspended parallel robots, and cooperative cable parallel manipulators for multiple mobile cranes. It also addresses the fundamental mechanics of cable-suspended parallel robots on the basis of their typical applications, including the kinematics, dynamics and trajectory tracking control of the feed cable-suspended structure for super antennae. In addition it proposes a novel hybrid-driven-based cable-suspended parallel robot that uses integrated mechanism design methods to improve the performance of traditional cable-suspended parallel robots. A comparative study on error and performance indices of hybrid-driven based and traditional cable-suspended parallel robots rounds out the coverage. This book addresses the needs of researchers, engineers and post-graduates in the field of cable-suspended parallel robots and related areas.

A few words about the series "Scientific Fundamentals of Robotics" should be said on the occasion of publication of the present monograph. This six-volume series has been conceived so as to allow the readers to master a contemporary approach to the construction and synthesis of con trol for manipulation ~obots. The authors' idea was to show how to use correct mathematical models of the dynamics of active spatial mecha nisms for dynamic analysis of robotic systems, optimal design of their mechanical parts based on the accepted criteria and imposed constraints, optimal choice of actuators, synthesis of dynamic control algorithms and their microcomputer implementation. In authors' oppinion this idea has been relatively successfully realized within the six-volume mono graphic series. Let us remind the readers of the books of this series. Volumes 1 and 2 are devoted to the dynamics and control algorithms of manipulation ro bots, respectively. They form the first part of the series which has a certain topic-related autonomy in the domain of the construction and application of the mathematical models of robotic mechanisms' dynamics.
