Book excerpt: Cette thèse de doctorat s'adresse tout particulièrement à deux groupes de personnes travaillant sur la cinématique des mécanismes parallèles : les ingénieurs mécaniciens et les géométriciens. À l'origine, ce travail devait être basé uniquement sur des concepts et des outils d'ingénierie. Cependant, à mi-parcours, il a été pertinent d'utiliser un aspect pratique de l'algèbre géométrique et, désormais, cette thèse se veut un judicieux mélange de ces deux approches. En effet, contrairement à ce qu'on trouve généralement dans la littérature, le travail présenté ici ne favorise pas une méthode par rapport à l'autre, mais vise plutôt à utiliser les synergies possibles entre les méthodes de l'ingénierie mécanique et de l'algèbre géométrique. En gardant comme étude de cas l'analyse cinématique de mécanismes parallèles symétriques à cinq degrés de liberté, trois translations et deux rotations, cette thèse peut être considérée comme une ligne directrice de l'application de l'algèbre géométrique dans l'analyse cinématique de mécanismes parallèles. Le choix de ce cas s'est avéré heureux puisque les propriétés cinématiques de ce type d'architecture se sont révélées tout à fait remarquables. Dans cette optique, les chapitres 2 à 4 sont consacrés à l'adaptation des outils de l'algèbre géométrique à l'analyse cinématique des mécanismes parallèles. Ces chapitres gardent toujours en toile de fond l'étude des mécanismes parallèles symétriques à cinq degrés de liberté. La contribution majeure du chapitre 2 est le développement d'une approche systématique pour la modélisation cinématique des mécanismes parallèles symétriques qui est appliquée par la suite dans le chapitre 3 aux mécanismes parallèles iii symétriques à cinq degrés de liberté. Cette application donne des résultats étonnants en ce qui a trait au nombre de solutions du problème géométrique direct : 1680 solutions finies et 208 solutions réelles pour une architecture donnée. Toutes ces solutions sont en termes de paramètres de Study, un espace projectif à sept dimensions. Au chapitre 4, la transformation entre cet espace à sept dimensions et celui à trois dimensions est introduite afin d'obtenir les coordonnées cartésiennes et les angles correspondants pour chaque solution. En outre, les propriétés cinématiques de premier ordre sont également étudiées dans ce chapitre afin d'avoir une meilleure compréhension du mécanisme. Le lecteur pourra ensuite suivre dans les chapitres 5 et 6 une étude cinématique basée sur l'espace à trois dimensions. La préoccupation principale du chapitre 5 est l'analyse constructive de l'espace atteignable par une approche géométrique. Un algorithme proposé dans la littérature pour trouver l'espace atteignable pour une orientation constante d'un mécanisme parallèle à six degrés de liberté est alors étendu aux mécanismes parallèles symétriques à cinq degrés de liberté. Le modèle CAO de l'espace atteignable est également présenté. Les résultats de ce chapitre montrent que l'espace atteignable des mécanismes parallèles symétriques à cinq degrés de liberté peut posséder une petite partie isolée. Le chapitre 6 complète quant à lui la réflexion engagée au chapitre 3 sur le problème géométrique direct. Ce problème est ainsi étudié pour des modèles simplifiés qui ont des solutions explicites ou une expression monovariable. Pour une conception quasi-générale, une expression monovariable de degré 220 est obtenue. Dans ce chapitre, nous dévions un peu de l'espace à trois dimensions pour celui à sept dimensions afin de valider et d'affiner les résultats obtenus, une approche qui peut être appliquée à d'autres cas. Le chapitre 7 est pour sa part consacré à l'analyse des singularités des mécanismes parallèles symétriques à cinq degrés de liberté qui repose sur la géométrie grassmanni-enne. Ce chapitre couvre largement l'étude des configurations singulières des mécanismes parallèles symétriques à cinq degrés de liberté pour les architectures simplifiées proposées dans le chapitre 6. La contribution principale de ce chapitre est l'application de la géométrie grassmannienne aux mécanismes parallèles à mobilité réduite pour lesquels une ligne à l'infini est parmi les lignes de Plùcker. Enfin, le chapitre 8 conclut cette thèse en résumant les résultats obtenus dans les chapitres précédents. Il décrit également plusieurs travaux en cours et propose des sujets de travaux futurs pour une nouvelle orientation de la recherche.

Book Synopsis Type Synthesis, Kinematics Analysis and Dynamic Modelling of Metamorphic Parallel Mechanisms by : Dongming Gan
Download or read book Type Synthesis, Kinematics Analysis and Dynamic Modelling of Metamorphic Parallel Mechanisms written by Dongming Gan and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: (2) Unified Kinematics and Dynamics Modelling of Metamorphic Parallel Mechanisms: Since each of all reconfigured phases of a metamorphic parallel mechanism is equivalent to a traditional parallel mechanism and all phases with different mobility share the same mechanical structure, a unified strategy has been proposed by considering the reconfiguration of the joint and taking the reconfigured phases as special cases of the general configuration. Some selected metamorphic parallel mechanisms have been studied and their unified kinematics, workspace representation, and dynamics modelling are solved. Thus this thesis provides basic synthesis, design, and modelling theory for metamorphic parallel mechanisms considering their reconfiguration and variable mobility.

Book Synopsis Dynamics of Parallel Robots by : Sébastien Briot
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.

Book Synopsis Geometric Method for Type Synthesis of Parallel Manipulators by : Qinchuan Li
Download or read book Geometric Method for Type Synthesis of Parallel Manipulators written by Qinchuan Li and published by Springer. This book was released on 2019-07-03 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the synthesis of lower-mobility parallel manipulators, presenting a group-theory-based method that has the advantage of being geometrically intrinsic. Rotations and translations of a rigid body as well as a combination of the two can be expressed and handled elegantly using the group algebraic structure of the set of rigid-body displacements. The book gathers the authors’ research results, which were previously scattered in various journals and conference proceedings, presenting them in a unified form. Using the presented method, it reveals numerous novel architectures of lower-mobility parallel manipulators, which are of interest to those in the robotics community. More importantly, readers can use the method and tool to develop new types of lower-mobility parallel manipulators independently.
Book Synopsis Computational Kinematics by : Jorge Angeles
Download or read book Computational Kinematics written by Jorge Angeles and published by Springer. This book was released on 1993-09-30 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide an account of the state of the art in Com putational Kinematics. We understand here under this term ,that branch of kinematics research involving intensive computations not only of the numer ical type, but also of a symbolic nature. Research in kinematics over the last decade has been remarkably ori ented towards the computational aspects of kinematics problems. In fact, this work has been prompted by the need to answer fundamental question s such as the number of solutions, whether real or complex, that a given problem can admit. Problems of this kind occur frequently in the analysis and synthesis of kinematic chains, when finite displacements are considered. The associated models, that are derived from kinematic relations known as closure equations, lead to systems of nonlinear algebraic equations in the variables or parameters sought. What we mean by algebraic equations here is equations whereby the unknowns are numbers, as opposed to differen tial equations, where the unknowns are functions. The algebraic equations at hand can take on the form of multivariate polynomials or may involve trigonometric functions of unknown angles. Because of the nonlinear nature of the underlying kinematic models, purely numerical methods turn out to be too restrictive, for they involve iterative procedures whose convergence cannot, in general, be guaranteed. Additionally, when these methods converge, they do so to only isolated solu tions, and the question as to the number of solutions to expect still remains.
Book Synopsis Theory of Parallel Mechanisms by : Zhen Huang
Download or read book Theory of Parallel Mechanisms written by Zhen Huang and published by Springer Science & Business Media. This book was released on 2012-07-26 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains mechanism analysis and synthesis. In mechanism analysis, a mobility methodology is first systematically presented. This methodology, based on the author's screw theory, proposed in 1997, of which the generality and validity was only proved recently, is a very complex issue, researched by various scientists over the last 150 years. The principle of kinematic influence coefficient and its latest developments are described. This principle is suitable for kinematic analysis of various 6-DOF and lower-mobility parallel manipulators. The singularities are classified by a new point of view, and progress in position-singularity and orientation-singularity is stated. In addition, the concept of over-determinate input is proposed and a new method of force analysis based on screw theory is presented. In mechanism synthesis, the synthesis for spatial parallel mechanisms is discussed, and the synthesis method of difficult 4-DOF and 5-DOF symmetric mechanisms, which was first put forward by the author in 2002, is introduced in detail. Besides, the three-order screw system and its space distribution of the kinematic screws for infinite possible motions of lower mobility mechanisms are both analyzed.

Book Synopsis Vehicle-Manipulator Systems by : Pål Johan From
Download or read book Vehicle-Manipulator Systems written by Pål Johan From and published by Springer Science & Business Media. This book was released on 2013-10-02 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Furthering the aim of reducing human exposure to hazardous environments, this monograph presents a detailed study of the modeling and control of vehicle-manipulator systems. The text shows how complex interactions can be performed at remote locations using systems that combine the manipulability of robotic manipulators with the ability of mobile robots to locomote over large areas. The first part studies the kinematics and dynamics of rigid bodies and standard robotic manipulators and can be used as an introduction to robotics focussing on robust mathematical modeling. The monograph then moves on to study vehicle-manipulator systems in great detail with emphasis on combining two different configuration spaces in a mathematically sound way. Robustness of these systems is extremely important and Modeling and Control of Vehicle-manipulator Systems effectively represents the dynamic equations using a mathematically robust framework. Several tools from Lie theory and differential geometry are used to obtain globally valid representations of the dynamic equations of vehicle-manipulator systems. The specific characteristics of several different types of vehicle-manipulator systems are included and the various application areas of these systems are discussed in detail. For underwater robots buoyancy and gravity, drag forces, added mass properties, and ocean currents are considered. For space robotics the effects of free fall environments and the strong dynamic coupling between the spacecraft and the manipulator are discussed. For wheeled robots wheel kinematics and non-holonomic motion is treated, and finally the inertial forces are included for robots mounted on a forced moving base. Modeling and Control of Vehicle-manipulator Systems will be of interest to researchers and engineers studying and working on many applications of robotics: underwater, space, personal assistance, and mobile manipulation in general, all of which have similarities in the equations required for modeling and control.
Book Synopsis Robots and Screw Theory by : J. K. Davidson
Download or read book Robots and Screw Theory written by J. K. Davidson and published by Oxford University Press. This book was released on 2004-03-25 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robots and Screw Theory describes the mathematical foundations, especially geometric, underlying the motions and force-transfers in robots. The principles developed in the book are used in the control of robots and in the design of their major moving parts. The illustrative examples and the exercises in the book are taken principally from robotic machinery used for manufacturing and construction, but the principles apply equally well to miniature robotic devices and to those used in other industries. The comprehensive coverage of the screw and its geometry lead to reciprocal screw systems for statics and instantaneous kinematics. These screw systems are brought together in a unique way to show many cross-relationships between the force-systems that support a body equivalently to a kinematic serial connection of joints and links. No prior knowledge of screw theory is assumed. The reader is introduced to the screw with a simple planar example yet most of the book applies to robots that move three-dimensionally. Consequently, the book is suitable both as a text at the graduate-course level and as a reference book for the professional. Worked examples on every major topic and over 300 exercises clarify and reinforce the principles covered in the text. A chapter-length list of references gives the reader source-material and opportunities to pursue more fully topics contained in the text.
