Contributions à l’imagerie polarimétrique et à ses applications en vision pour la robotique

2019

Ce mémoire présente le bilan de l'ensemble de mes travaux de recherche effectués de septembre 2006 à juin 2019 au sein de l'équipe Creusotine du laboratoire Le2i devenue équipe Vibot ERL CNRS 6000 depuis janvier 2018. Les principales activités de recherche que j'ai menées au cours de ces 10 dernières années autour de l'imagerie polarimétrique, de la vision omnidirectionnelle et de leurs applications en vision pour la robotique seront particulièrement détaillées dans ce document. Elles seront présentées selon deux grandes parties : la première concernera plutôt l'aspect mise en œuvre et calibrage des caméras et la seconde se concentrera sur les applications potentielles en vision pour la rob…

ROS - Robotiikan tutkimustyökalusta kohti kaupallista menestystarinaa

2017

Avoimen lähdekoodin ROS-käyttöjärjestelmä on yleisesti tutkimushankkeissa käytetty robotiikan kehitysalusta. Tutkielman tavoitteena on ollut arvioida onko ROS järjestelmä, joka tulee yleistymään myös robotiikan kaupallisissa ratkaisuissa. ROS-pohjaisia kaupallisia tuotteita on jo olemassa ja sen käyttöä on pilotoitu runsaasti erilaisilla sovellusalueilla. Erityisesti palvelu- ja pilvirobotiikan alueilla ROSilla on kasvavaa potentiaalia. ROS on vielä kehittyvä järjestelmä ja ei nykyisellään sovellu kriittisimpiin robotiikan tehtäviin. Kuitenkin järjestelmän tuleva versio ROS 2.0 antaa lupauksia siitä, että teknologia on sovellettavissa yhä useimmilla laitealustoilla ja sovellutuksissa tuleva…

Motions with Emotions? : A Phenomenological Approach to Understanding the Simulated Aliveness of a Robot Body

2019

This article examines how the interactive capabilities of companion robots, particularly their materiality and animate movements, appeal to human users and generate an image of aliveness. Building on Husserl’s phenomenological notion of a ‘double body’ and theories of emotions as affective responses, we develop a new understanding of the robots’ simulated aliveness. Analyzing empirical findings of a field study on the use of the robot Zora in care homes for older people, we suggest that the aliveness of companion robots is the result of a combination of four aspects: 1) material ingredients, 2) morphology, 3) animate movements guided by software programs and human operators as in Wizard of …

On the Stability of the Soft Pendulum With Affine Curvature: Open-Loop, Collocated Closed-Loop, and Switching Control

2022

This letter investigates the stability properties of the soft inverted pendulum with affine curvature - a template model for nonlinear control of underactuated soft robots. We look at how changes in physical parameters affect stability and equilibrium. We give conditions under which zero dynamics corresponding to a collocated choice of the output is (locally or globally) stable or unstable. We leverage these results to design a switching controller that stabilizes a class of nonlinear equilibria of the pendulum, which can drive the system from one equilibrium to another.

Do humans dream of prophetic robots?

2020

Social robotics is a technology that, as its definition varies, encompasses conceptually diverse fields materializing in innovations from simple chatbots to sophisticated androids talking about the peaceful coexistence of humans and robots. The advances in social robotics have led to promising applications in education, work, entertainment, and even religion. Yet a measure of fear and confusion about the capabilities of contemporary and future robots exists, with one of the reasons being the presentation of some contemporary robots as being more advanced than they really are.

Kinematic and Elastostatic Design Optimisation of the 3-DOF Gantry-Tau Parallel Kinematic Manipulator

2009

Published version of an article in the journal: Modeling Identification and Control. Also available from the publisher:http://dx.doi.org/10.4173/mic.2009.2.1 One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The Gantry-Tau improves this ration further by allowing a change of assembly mode without internal link collisions or collisions between the links and end-effector. The reconfigurable Gantry-Tau kinematic design obtained by multi-objective optimisation according to this paper gives the following features: 3-D workspace/footprint ration is more than 3.19, lowest Cartesian stiffness in the workspa…

Étude d'un système de stéréo-vision hybride

2013

National audience; On considère dans ce travail un système de vision hybride fixe composé d'une caméra fisheye et d'une caméra PTZ dans un environnement rigide. Nous souhaitons être en mesure d'orienter la caméra mécanisée sur une cible visible depuis l'image omnidirectionnelle de manière à obtenir une image de bonne définition de l'objet d'intérêt à partir de la caméra PTZ. Nous proposons dans cet article d'utiliser la modélisation sphérique des images ainsi que les propriétés de la géométrie épipolaire afin d'initialiser la localisation de la cible dans la caméra PTZ.
