This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Parallel Robots With Unconventional Joints written by Patrick Grosch and published by Springer. This book was released on 2019-03-20 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how, through certain geometric transformations, some of the standard joints used in parallel robots can be replaced with lockable or non-holonomic joints. These substitutions allow for reducing the number of legs, and hence the number of actuators needed to control the robot, without losing the robot's ability to bring its mobile platform to the desired configuration. The kinematics of the most representative examples of these new designs are analyzed and their theoretical features verified through simulations and practical implementations.

Book excerpt: The objective of this book is to provide those interested in the field of flexible robotics with an overview of several scientific and technological advances in the practical field of robotic manipulation. The different chapters examine various stages that involve a number of robotic devices, particularly those designed for manipulation tasks characterized by mechanical flexibility. Chapter 1 deals with the general context surrounding the design of functionally integrated microgripping systems. Chapter 2 focuses on the dual notations of modal commandability and observability, which play a significant role in the control authority of vibratory modes that are significant for control issues. Chapter 3 presents different modeling tools that allow the simultaneous use of energy and system structuring notations. Chapter 4 discusses two sensorless methods that could be used for manipulation in confined or congested environments. Chapter 5 analyzes several appropriate approaches for responding to the specific needs required by versatile prehension tasks and dexterous manipulation. After a classification of compliant tactile sensors focusing on dexterous manipulation, Chapter 6 discusses the development of a complying triaxial force sensor based on piezoresistive technology. Chapter 7 deals with the constraints imposed by submicrometric precision in robotic manipulation. Chapter 8 presents the essential stages of the modeling, identification and analysis of control laws in the context of serial manipulator robots with flexible articulations.

Download or read book Dynamics of Parallel Robots written by Sébastien Briot and published by Springer. This book was released on 2015-06-22 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book starts with a short recapitulation on basic concepts, common to any types of robots (serial, tree structure, parallel, etc.), that are also necessary for computation of the dynamic models of parallel robots. Then, as dynamics requires the use of geometry and kinematics, the general equations of geometric and kinematic models of parallel robots are given. After, it is explained that parallel robot dynamic models can be obtained by decomposing the real robot into two virtual systems: a tree-structure robot (equivalent to the robot legs for which all joints would be actuated) plus a free body corresponding to the platform. Thus, the dynamics of rigid tree-structure robots is analyzed and algorithms to obtain their dynamic models in the most compact form are given. The dynamic model of the real rigid parallel robot is obtained by closing the loops through the use of the Lagrange multipliers. The problem of the dynamic model degeneracy near singularities is treated and optimal trajectory planning for crossing singularities is proposed. Lastly, the approach is extended to flexible parallel robots and the algorithms for computing their symbolic model in the most compact form are given. All theoretical developments are validated through experiments.

This book was released on 2010-11-20 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although parallel robots are known to offer many advantages with respect to accuracy, dynamics, and stiffness, major breakthroughs in industrial applications have not yet taken place. This is due to a knowledge gap preventing fast and precise execution of industrial handling and assembly tasks. This book focuses on the design, modeling, and control of innovative parallel structures as well as the integration of novel machine elements. Special attention is paid to the integration of active components into lightweight links and passive joints. In addition, new control concepts are introduced to minimize structural vibrations. Although the optimization of robot systems itself allows a reduction of cycle times, these can be further decreased by improved path planning, robot programming, and automated assembly planning concepts described by 25 contributions within this book. The content of this volume is subdivided into four main parts dealing with Modeling and Design, System Implementation, Control and Programming as well as Adaptronics and Components. This book is aimed at researchers and postgraduates working in the field of parallel robots as well as practicing engineers dealing with industrial robot development and robotic applications.

This book was released on 2013-12-11 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Wearable Robots written by José L. Pons and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wearable robot is a mechatronic system that is designed around the shape and function of the human body, with segments and joints corresponding to those of the person it is externally coupled with. Teleoperation and power amplification were the first applications, but after recent technological advances the range of application fields has widened. Increasing recognition from the scientific community means that this technology is now employed in telemanipulation, man-amplification, neuromotor control research and rehabilitation, and to assist with impaired human motor control. Logical in structure and original in its global orientation, this volume gives a full overview of wearable robotics, providing the reader with a complete understanding of the key applications and technologies suitable for its development. The main topics are demonstrated through two detailed case studies; one on a lower limb active orthosis for a human leg, and one on a wearable robot that suppresses upper limb tremor. These examples highlight the difficulties and potentialities in this area of technology, illustrating how design decisions should be made based on these. As well as discussing the cognitive interaction between human and robot, this comprehensive text also covers: the mechanics of the wearable robot and it’s biomechanical interaction with the user, including state-of-the-art technologies that enable sensory and motor interaction between human (biological) and wearable artificial (mechatronic) systems; the basis for bioinspiration and biomimetism, general rules for the development of biologically-inspired designs, and how these could serve recursively as biological models to explain biological systems; the study on the development of networks for wearable robotics. Wearable Robotics: Biomechatronic Exoskeletons will appeal to lecturers, senior undergraduate students, postgraduates and other researchers of medical, electrical and bio engineering who are interested in the area of assistive robotics. Active system developers in this sector of the engineering industry will also find it an informative and welcome resource.
