Book excerpt: Les mécanismes parallèles sont fréquemment utilisés comme robots manipulateurs, comme simulateurs de mouvement, comme machines parallèles, etc. Cependant, à cause des chaînes cinématiques fermées qui caractérisent leur architecture, le mouvement de leur plateforme est limité et des singularités cinématiques complexes peuvent apparaître à l'intérieur de leur espace de travail. Par conséquent, une maximisation l'espace de travail libre de singularité pour ce type de mécanismes est souhaitable dans un contexte de conception. Dans cette thèse, deux types de mécanismes parallèles sont étudiés: les mécanismes parallèles plans ?avec, en particulier le 3-RPR? et les mécanismes spatiaux ?avec, en particulier, la plateforme de Gough-Stewart. Pour chaque type de mécanisme parallèle, une forme simple d'équation de singularité est obtenue. Le principe consiste à séparer l'origine O' du repère mobile du point considéré P et de faire coïncider O' avec un point particulier de la plateforme. L'équation ainsi obtenue est l'équation de singularité du point P de la plateforme qui contient un ensemble minimal de paramètres géométriques. Par ailleurs, il est prouvé que les centres des cercles et sphères définissant l'espace de travail se trouvent exactement sur les lieux de singularité. Cette observation et l'équation de singularité simplifiée constituent les points de départ de l'analyse de l'espace de travail libre de singularité ainsi que de l'optimisation géométrique. Pour le mécanisme parallèle plan 3-RPR, l'espace de travail libre de singularité et les limites correspondantes pour la longueur des pattes dans une orientation prescrite sont déterminés. Ensuite l'architecture optimale qui permet d'obtenir un espace de travail maximal tout en étant libre de singularité est discutée. En ce qui concerne la plateforme de Gough-Stewart, cette thèse se concentre sur le manipulateur symétrique simplifié minimal (MSSM). Comme une plateforme de Gough- Stewart a 6 degrés de liberté, son espace de travail se divise en deux: l'espace de travail en position (ou simplement espace de travail) et l'espace de travail en orientation. A partir de l'équation de singularité simplifiée, une procédure générale est développée afin de déterminer l'espace de travail libre de singularité maximal autour d'un point particulier dans une orientation donnée, et afin de déterminer les limites correspondantes des longueurs de patte. Dans le but de maximiser l'espace de travail libre de singularité en orientation, un algorithme est présenté qui optimise les trois angles d'orientation. Sachant qu'une plateforme fonctionne habituellement pour une certaine gamme d'orientations, deux algorithmes qui calculent l'espace de travail en orientation libre de singularité maximal sont présentés. En utilisant les angles d'Euler en roulis, tangage et lacet, l'espace de travail en orientation pour une position prescrite peut être défini par 12 surfaces. Basé sur ce fait, un algorithme numérique est présenté qui évalue et représente l'espace de travail en orientation pour une position prescrite dans les limites données de longueur de patte. Ensuite, une procédure est proposée afin de déterminer l'espace de travail en orientation libre singularité maximal ainsi que les limites correspondantes des longueurs de patte. En pratique, une plateforme peut fonctionner dans un ensemble de positions. Ainsi, l'effet de la position de travail sur l'espace de travail en orientation libre de singularité maximal est analysé et deux algorithmes sont proposés pour calculer ce dernier pour tout un ensemble de positions particulières. Finalement, un algorithme qui optimise les paramètres géométriques est développé dans le but de déterminer l'architecture optimale qui permet à la plateforme de MSSM Gough-Stewart d'obtenir l'espace de travail libre singularité maximal autour d'une position particulière pour l'orientation de référence. Les résultats obtenus peuvent être utilisés pour la conception géométrique, la configuration des paramètres (longueur des pattes) ou la planification de trajectoires libres de singularité des mécanismes parallèles considérés. En outre, les algorithmes proposés peuvent également être appliqués à d'autres types de mécanismes parallèles.

Book excerpt: “In other words, the invention of a mechanism will be to the scientific kinematist a synthetic problem, - which he can solve by the use of systematic, if also difficult, methods.” Reuleaux, F., Theoretische Kinematik, Braunschweig: Vieweg, 1875 Reuleaux, F., The Kinematics of Machinery, London: Macmillan, 1876 and New York: Dover, 1963 (translated by A.B.W. Kennedy) This book represents the third part of a larger work dedicated to the structural synthesis of parallel robots. Part 1 (Gogu 2008a) presented the methodology of structural synthesis and the systematisation of structural solutions of simple and complex limbs with two to six degrees of connectivity systematically generated by the structural synthesis approach. Part 2 (Gogu 2009a) presented structural solutions of translational parallel robotic manipulators with two and three degrees of mobility. This book focuses on various topologies of parallel robotic manipulators with planar motion of the moving platform systematically generated by using the structural synthesis approach proposed in Part 1. The originality of this work resides in the fact that it combines the new formulae for mobility connectivity, redundancy and overconstraints, and the evolutionary morphology in a unified approach of structural synthesis giving interesting innovative solutions for parallel mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the singular configurations associated with a robot mechanism, together with robust methods for their computation, interpretation, and avoidance path planning. Having such methods is essential as singularities generally pose problems to the normal operation of a robot, but also determine the workspaces and motion impediments of its underlying mechanical structure. A distinctive feature of this volume is that the methods are applicable to nonredundant mechanisms of general architecture, defined by planar or spatial kinematic chains interconnected in an arbitrary way. Moreover, singularities are interpreted as silhouettes of the configuration space when seen from the input or output spaces. This leads to a powerful image that explains the consequences of traversing singular configurations, and all the rich information that can be extracted from them. The problems are solved by means of effective branch-and-prune and numerical continuation methods that are of independent interest in themselves. The theory can be put into practice as well: a companion web page gives open access to implementations of the algorithms and the corresponding input files. Using them, the reader can gain hands-on experience on the topic, or analyse new mechanisms beyond those examined in the text. Overall, the book contributes new tools for robot design, and constitutes a single reference source of knowledge that is otherwise dispersed in the literature.

This work also includes new methods for the analysis in different applications, which are important in the proposal of new paradigms. Modeling is presented in applications oriented to a better understanding of biosystems; on the other hand, we also have applications of intelligent systems that enrich and complement the analysis of movement and position. Definitely, we hope that the present research work enriches and contributes with ideas and elements of interest for each of our readers.

Book excerpt: With a rigorous and comprehensive coverage, the second edition of Compliant Mechanisms: Design of Flexure Hinges provides practical answers to the design and analysis of devices that incorporate flexible hinges. Complex-shaped flexible-hinge mechanisms are generated from basic elastic segments by means of a bottom-up compliance (flexibility) approach. The same compliance method and the classical finite element analysis are utilized to study the quasi-static and dynamic performances of these compliant mechanisms. This book offers easy-to-use mathematical tools to investigate a wealth of flexible-hinge configurations and two- or three-dimensional compliant mechanism applications. FEATURES Introduces a bottom-up compliance-based approach to characterize the flexibility of new and existing flexible hinges of straight- and curvilinear-axis configurations Develops a consistent linear lumped-parameter compliance model to thoroughly describe the quasi-static and dynamic behavior of planar/spatial, serial/parallel flexible-hinge mechanisms Utilizes the finite element method to analyze the quasi-statics and dynamics of compliant mechanisms by means of straight- and curvilinear-axis flexible-hinge elements Covers miscellaneous topics such as stress concentration, yielding and related maximum load, precision of rotation of straight- and circular-axis flexible hinges, temperature effects on compliances, layered flexible hinges and piezoelectric actuation/sensing Offers multiple solved examples of flexible hinges and flexible-hinge mechanisms. This book should serve as a reference to students, researchers, academics and anyone interested to investigate precision flexible-hinge mechanisms by linear model-based methods in various areas of mechanical, aerospace or biomedical engineering, as well as in robotics and micro-/nanosystems.
