Book excerpt: Stucture simple, faible coût, grand espace de travail et technologie mature, ces avantages font que les manipulateurs sériels sont largement utilisés dans de nombreux domaines industriels. Avec le développement rapide de l'industrie et les diverses applications des manipulateurs sériels, de nouvelles exigences strictes sont souhaitées, telles que la stabilité robuste, la grande précision de positionnement et la cadence élevée.Un des moyens efficaces pour améliorer les performances mentionnées est la conception de manipulateurs sériels à découplage dynamique. Dans ce cadre, l'objectif de cette thèse est de valider une structure simple permettant de réaliser un découplage dynamique complet des manipulateurs sériels en tenant compte de la charge embarquée.Le chapitre 1 présente les solutions connues et décrit les inconvénients liés aux différentes techniques permettant une simplification de la dynamique des manipulateurs. L'étude de la bibliographie a permis d'affiner les objectifs à atteindre. Le chapitre 2 traite de la conception de manipulateurs sériels réglables à dynamique linéarisée et découplée. Sans la charge embarquée, la méthode développée réalise le découplage dynamique par rotation inverse des bras et par redistribution optimale des masses. La charge embarquée qui conduit à une perturbation au niveau des équations dynamiques dedécouplage est compensée par la commande.Le chapitre 3 envisage un nouveau concept de découplage dynamique qui consiste à relier aux bras initiaux d'un manipulateur sériel, deux bras additionnels pour réaliser un mécanisme Scott-Russell. Les mouvements opposés des bras du mécanisme Scott-Russell associés à une redistribution optimale des masses permettent de supprimer les termes non linéaires des équations dynamiques du manipulateur. Le modèle linéaire et découplé ainsi obtenu permet de tenir compte de la charge embarquée.Dans le chapitre 4, on considère les propriétés de robustesse (incertitudes paramétriques) de quatre modèles de manipulateurs sériels (un manipulateur couplé, un manipulateur découplé par la commande et les deux manipulateurs découplés qui sont issus des chapitres 2 et 3). Les études qualitatives sont effectuées par simulation en utilisant la même loi de commande optimale et la même trajectoire de référence. Les résultats des simulations permettentde conclure sur la robustesse des manipulateurs décrits aux chapitres 2 et 3 par rapport au manipulateur couplé et au manipulateur découplé par la commande.La méthodologie de conception et les techniques de commande proposées sont illustrées par des simulations réalisées à l'aide des logiciels ADAMS et MATLAB. Les simulations ont confirmé l'efficacité des approches développées.
Book Synopsis Dynamic Decoupling of Robot Manipulators by : Vigen Arakelian
Download or read book Dynamic Decoupling of Robot Manipulators written by Vigen Arakelian and published by Springer. This book was released on 2018-02-20 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest results in the field of dynamic decoupling of robot manipulators obtained in France, Russia, China and Austria. Manipulator dynamics can be highly coupled and nonlinear. The complicated dynamics result from varying inertia, interactions between the different joints, and nonlinear forces such as Coriolis and centrifugal forces. The dynamic decoupling of robot manipulators allows one to obtain a linear system, i.e. single-input and single output system with constant parameters. This simplifies the optimal control and accumulation of energy in manipulators. There are two ways to create the dynamically decoupled manipulators: via optimal mechanical design or control. This work emphasises mechatronic solutions. These will certainly improve the known design concepts permitting the dynamic decoupling of serial manipulators with a relatively small increase in total mass of the moving links taking into account the changing payload. For the first time such an approach has been applied on serial manipulators. Also of great interest is the dynamic decoupling control of parallel manipulators. Firstly, the dynamic model of redundant multi-axial vibration table with load has been established, and, secondly, its dynamic coupling characteristics have been analyzed. The discussed methods and applications of dynamic decoupling of robot manipulators are illustrated via CAD simulations and experimental tests.

Download or read book Biologically Inspired Robotics written by Yunhui Liu and published by CRC Press. This book was released on 2011-12-21 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robotic engineering inspired by biology—biomimetics—has many potential applications: robot snakes can be used for rescue operations in disasters, snake-like endoscopes can be used in medical diagnosis, and artificial muscles can replace damaged muscles to recover the motor functions of human limbs. Conversely, the application of robotics technology to our understanding of biological systems and behaviors—biorobotic modeling and analysis—provides unique research opportunities: robotic manipulation technology with optical tweezers can be used to study the cell mechanics of human red blood cells, a surface electromyography sensing system can help us identify the relation between muscle forces and hand movements, and mathematical models of brain circuitry may help us understand how the cerebellum achieves movement control. Biologically Inspired Robotics contains cutting-edge material—considerably expanded and with additional analysis—from the 2009 IEEE International Conference on Robotics and Biomimetics (ROBIO). These 16 chapters cover both biomimetics and biorobotic modeling/analysis, taking readers through an exploration of biologically inspired robot design and control, micro/nano bio-robotic systems, biological measurement and actuation, and applications of robotics technology to biological problems. Contributors examine a wide range of topics, including: A method for controlling the motion of a robotic snake The design of a bionic fitness cycle inspired by the jaguar The use of autonomous robotic fish to detect pollution A noninvasive brain-activity scanning method using a hybrid sensor A rehabilitation system for recovering motor function in human hands after injury Human-like robotic eye and head movements in human–machine interactions A state-of-the-art resource for graduate students and researchers in the fields of control engineering, robotics, and biomedical engineering, this text helps readers understand the technology and principles in this emerging field.
Book Synopsis Robot Force Control by : Bruno Siciliano
Download or read book Robot Force Control written by Bruno Siciliano and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the fundamental requirements for the success of a robot task is the capability to handle interaction between manipulator and environment. The quantity that describes the state of interaction more effectively is the contact force at the manipulator's end effector. High values of contact force are generally undesirable since they may stress both the manipulator and the manipulated object; hence the need to seek for effective force control strategies. The book provides a theoretical and experimental treatment of robot interaction control. In the framework of model-based operational space control, stiffness control and impedance control are presented as the basic strategies for indirect force control; a key feature is the coverage of six-degree-of-freedom interaction tasks and manipulator kinematic redundancy. Then, direct force control strategies are presented which are obtained from motion control schemes suitably modified by the closure of an outer force regulation feedback loop. Finally, advanced force and position control strategies are presented which include passivity-based, adaptive and output feedback control schemes. Remarkably, all control schemes are experimentally tested on a setup consisting of a seven-joint industrial robot with open control architecture and force/torque sensor. The topic of robot force control is not treated in depth in robotics textbooks, in spite of its crucial importance for practical manipulation tasks. In the few books addressing this topic, the material is often limited to single-degree-of-freedom tasks. On the other hand, several results are available in the robotics literature but no dedicated monograph exists. The book is thus aimed at filling this gap by providing a theoretical and experimental treatment of robot force control.
