Available in PDF, EPUB and Kindle. Book excerpt: Ce travail est une contribution à l'étude du comportement des robots par la simulation. Nous proposons des outils pour le test de composants logiciels contribuant à faire d'un robot une machine qui agit et perçoit dans un environnement. Différentes représentations du robot et de son environnement sont articulées:―des composants d'émulation du robot fonctionnellement constitué de dispositifs et de composants logiciels pour l'action et la perception; le robot est alors vu comme acteur d'un scénario;―un noyau de simulation qui gère le déroulement d'un scénario dans un décor virtuel, en répondant aux requêtes d'action et de perception émulées. Le noyau de simulation utilise des représentations de l'environnement, de la partie matérielle du robot et de lois physiques régissant leurs évolutions et leurs interactions. Des maquettes de tels outils sont appliquées à l'étude de composants logiciels pour deux applications robotiques: un interpréteur pour l'exécution de tâches de découpe laser par un robot à cinq axes, et un planificateur réactif de missions d'un engin mobile. Nous spécifions ensuite des outils plus généraux, développés en langage Ada. Une version simplifiée est appliquée l'émulation/simulation d'un robot mobile doté d'un composant logiciel de navigation réflexe.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Multi-rigid body dynamics simulation supports design, prototype, test, and evolutionary stages of robotic development. However, the reliability of simulating tasks critical to robotics, i.e. grasping and locomotion, remains low and represents a barrier to future robotics applications. A lack of simulation reliability is typically exhibited by a simulated robot performing a task while under similar conditions the real system fails to perform that same task. Simulations that are not reliable may mislead roboticists into costly, infeasible designs or give false safety assurances of systems where safety is paramount, e.g. autonomous vehicles. Roboticists therefore need assurances that simulation will either consistently predict real performance or indicate that it can not make sound predictions. General software engineering proposes verification and validation as practices for quality assurance. In simulation software, verification checks that implementation is consistent with theory, and validation checks that simulation is consistent with real behaviors. While verification is critical, validation is necessary to objectively demonstrate simulation consistency.This thesis studies validation of multi-body rigid body dynamics simulations with contact and friction in an effort to improve the state of the art in robotics simulation. This work identifies scenarios relevant to robotics tasks, examines simulators performing these tasks, and identifies ways that current simulators should be used and future simulators should be improved. Additionally, this work identifies temporal consistency as a critical requirement for robotics simulators, proposes a temporally consistent simulator architecture, and studies the performance difference between temporally consistent and existing robotics simulators. Finally, this work studies the motion of a minimally simple, yet still sophisticated, real world robot that we can model and examines a means to validate simulation of the robot.

This book was released on 2010-06-21 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Francis BACON, in his Novum Organum, Robert BOYLE, in his Skeptical Chemist and René DESCARTES, in his Discourse on Method; all of these men were witnesses to the th scientific revolution, which, in the 17 century, began to awaken the western world from a long sleep. In each of these works, the author emphasizes the role of the experimental method in exploring the laws of Nature, that is to say, the way in which an experiment is designed, implemented according to tried and tested te- niques, and used as a basis for drawing conclusions that are based only on results, with their margins of error, taking into account contemporary traditions and prejudices. Two centuries later, Claude BERNARD, in his Introduction to the Study of Experimental Medicine, made a passionate plea for the application of the experimental method when studying the functions of living beings. Twenty-first century Biology, which has been fertilized by highly sophisticated techniques inherited from Physics and Chemistry, blessed with a constantly increasing expertise in the manipulation of the genome, initiated into the mysteries of information techn- ogy, and enriched with the ever-growing fund of basic knowledge, at times appears to have forgotten its roots.

Download or read book Virtual Crowds written by Nuria Palechano and published by Springer Nature. This book was released on 2022-05-31 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many applications of computer animation and simulation where it is necessary to model virtual crowds of autonomous agents. Some of these applications include site planning, education, entertainment, training, and human factors analysis for building evacuation. Other applications include simulations of scenarios where masses of people gather, flow, and disperse, such as transportation centers, sporting events, and concerts. Most crowd simulations include only basic locomotive behaviors possibly coupled with a few stochastic actions. Our goal in this survey is to establish a baseline of techniques and requirements for simulating large-scale virtual human populations. Sometimes, these populations might be mutually engaged in a common activity such as evacuation from a building or area; other times they may be going about their individual and personal agenda of work, play, leisure, travel, or spectator. Computational methods to model one set of requirements may not mesh well with good approaches to another. By including both crowd and individual goals and constraints into a comprehensive computational model, we expect to simulate the visual texture and contextual behaviors of groups of seemingly sentient beings.

Download or read book Law Public Policies and Complex Systems Networks in Action written by Romain Boulet and published by Springer. This book was released on 2019-05-07 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates how various scientific communities – e.g. legal scientists, political scientists, sociologists, mathematicians, and computer scientists – study law and public policies, which are portrayed here as complex systems. Today, research on law and public policies is rapidly developing at the international level, relying heavily on modeling that employs innovative methods for concrete implementation. Among the subject matter discussed, law as a network of evolving and interactive norms is now a prominent sphere of study. Similarly, public policies are now a topic in their own right, as policy can no longer be examined as a linear process; rather, its study should reflect the complexity of the networks of actors, norms and resources involved, as well as the uncertainty or weak predictability of their direct or indirect impacts. The book is divided into three maain parts: complexity faced by jurists, complexity in action and public policies, and complexity and networks. The main themes examined concern codification, governance, climate change, normative networks, health, water management, use-related conflicts, legal regime conflicts, and the use of indicators.
