Visual Control of a Robotic Hand

2004

The paper deals with the design and implementation of a visual control of a robotic system composed of a dexterous hand and stereo cameras. The aim of the proposed system is to reproduce the movements of a human hand in order to learn complex manipulation tasks. A novelty algorithm for a robust and fast fingertips localization and tracking is presented. Moreover, a simulator is integrated in the system to give useful feedbacks to the users during operations, and provide robust testing framework for real experiments (see video).

A Posture Sequence Learning System for an Anthropomorphic Robotic Hand

2003

The paper presents a cognitive architecture for posture learning of an anthropomorphic robotic hand. Our approach is aimed to allow the robotic system to perform complex perceptual operations, to interact with an human user and to integrate the perceptions by a cognitive representation of the scene and the observed actions. The anthropomorphic robotic hand imitates the gestures acquired by the vision system in order to learn meaningful movements, to build its knowledge by different conceptual spaces and to perform complex interaction with the human operator.

Does the brain know who is at the origin of what in an imitative interaction?

2012

International audience; Brain correlates of the sense of agency have recently received increased attention. However, the explorations remain largely restricted to the study of brains in isolation. The prototypical paradigm used so far consists of manipulating visual perception of own action while asking the subject to draw a distinction between self- versus externally caused action. However, the recent definition of agency as a multifactorial phenomenon combining bottom-up and top-down processes suggests the exploration of more complex situations. Notably there is a need of accounting for the dynamics of agency in a two-body context where we often experience the double faceted question of w…

Modèles et contre-modèles de société : représentations, exemplarité, contestations

2016

International audience; Les notions de « modèle » et de « contre-modèle » ont fédéré la réflexion d’un groupe interdisciplinaire de chercheurs en sciences humaines dans le cadre d’un séminaire de deux années (2012-2014). Les perpétuels changements de nos formes de pensée et de nos modes de diffusion des savoirs, des identités et des schémas culturels ont créé des jeux de tension particulièrement sensibles entre ces deux notions. Au point que d’autresconcepts ont été mobilisés pour les étudier : l’imitation, la reproduction, la réduction et la représentation simplifiée. Ils ont été essentiels pour chaque spécialité, lettres classiques, littérature britannique, musicologie contemporaine, civi…

Caractérisation de la distribution spatiale des communautés microbiennes du sol et de ses déterminants à l’échelle du paysage

2014

International audience; Depuis plusieurs années, des approches biogéographiques ont été développées pour mieux caractériser la distribution spatiale des communautés microbiennes du sol, comprendre les processus écologiques mis en œuvre et identifier les filtres environnementaux déterminant leur diversité et leur structure. Ces approches ont été mises en œuvre à différentes échelles spatiales allant de celle de la parcelle agricole à celle d’un territoire et d’un continent. Elles ont permis de mettre en évidence que les communautés microbiennes du sol sont distribuées suivant des patterns biogéographiques non aléatoire et que ces dernières sont soumises à des processus déterministes (sélecti…

Spatial processes driving soil microbial community assembly on a wide scale

2012

International audience; Soil houses a huge biodiversity involved in ecological services through microbial community assembly. However, processes driving soil microbial community assembly are still scarcely understood, particularly the relative importance of environmental heterogeneity regarding to dispersal limitations. This can be achieved through studying the determinism of taxa-area relationship (TAR, how community composition change with geographic distance), a fundamental relationship in ecology. Here, a biogeographical approach was applied on a wide scale to evaluate TAR for soil bacterial and fungal communities and to partition their spatial variations into environmental heterogeneit…

D’autres Héroïdes : les Epistulae heroides de Mark-Alexander Boyd (1592)

2022

The Scotsman Mark Alexander Boyd proposes, in his 1592 collection, "other heroids", in which he gives voice to more diverse women than Ovid did. The article focuses on four epistles written in a Roman context (letters from Rhea Silvia to Mars, from Lavinia to Turnus, from Sophonisbe to Massinissa and from Pauline to Mundus), analyzes the modalities of Ovid's imitation, while underlining some original elements on Boyd's part.

‘Oft turning others' leaves' : la contrainte de l' imitatio dans les sonnets anglais des XVIe et XVIIe siècles

2009

In the sixteenth and the seventeenth centuries, imitation was not usually considered a constraint by poets. Yet Sir Philip Sidney, in his sonnet cycle Astrophil and Stella, seems to advocate a new form of poetic writing based on personal experience and originality, even if he uses the traditional device of impossible love imitated from Petrarchan sonneteers. Stella appears as a new constraint, and her absence and coldness trigger a reflection on the impossibility to write.
