Home - Pierre-Yves Oudeyer

I am research director (DR1) at Inria, heading the Flowers team (see PhD students). I was previously a permanent researcher in Sony Computer Science Laboratory for 8 years (1999-2007). I am also editor of IEEE CIS Newsletter on Cognitive and Developmental Systems where I organize interdisciplinary dialogs in cognitive science, AI and robotics, as well as associate editor of IEEE Transactions on Cognitive and Developmental Systems and Frontiers in Neurorobotics. I have been chair of IEEE CIS Technical Committee on Cognitive and Developmental Systems in 2015-16.

I study computational mechanisms allowing robots and humans to acquire open-ended repertoires of skills through lifelong learning. This includes natural and artificial intelligence processes for progressively discovering their bodies and interaction with objects, tools and others. In particular, I study mechanisms of exploration in autonomous learning, and how they can self-organize curriculum learning. This includes mechanisms of intrinsically motivated learning (also called curiosity-driven active learning), autonomous unsupervised exploration, imitation and social learning, multimodal statistical inference, embodiment and maturation and self-organization.

I consider cognitive development as a complex dynamical system which needs to be understood through systemic thinking, leveraging tools and concepts from computational sciences (artificial intelligence, machine learning and robotics), neuroscience and psychology. I consider algorithms and robotics models as powerful scientific languages to express theories of cognitive development in the living.

Of particular interest to me is are the mechanisms of intrinsically motivated goal exploration, enabling humans and machines to self-generate, self-select and self-order their own goals for unsupervised learning of repertoires of sensorimotor and interaction skills as well as their relation with the acquisition and evolution of languages.

I am also working on applications of this research in three fields: adaptive human-computer interfaces, educational technologies and open-source robotics for art and education.

In practice, this has led me to follow two mutually reinforcing research activities (yet with two different epistemological perspectives):

Cognitive science: understanding human cognitive development, where computers and robots are used as conceptual and experimental tools in constant dialog with developmental psychology, neuroscience and linguistics (see an overview in these slides).
Artificial intelligence: constructing machines and robots, inspired by mechanisms of the living, which are capable of lifelong development and adaptation to the physical and social world, including mechanisms of autonomous unsupervised exploration and learning (see an overview in these slides).

Outreach Projects

Poppy: an Open-Source 3D Printed Robotic Platform

Link to information about the Poppy humanoid robot : Poppy Project web site. Poppy is an open-source 3D printed robot for science, education and art designed by the Flowers team. It was built to study the impact of the body on sensorimotor development and cognition: it makes it possible to really consider the body as an experimental variable. See article at Humanoids 2013 conference.

IniRobot: un kit pédagogique pour l'initiation à la robotique à l'école primaire

IniRobot: IniRobot est une série d’activités pédagogiques “clés en main” destinée à la découverte de la robotique et de la programmation à l’école primaire, en particulier lors des activités périscolaires. Ce kit est libre d’utilisation (Creative Commons CC-BY-SA) et utilise le robot Thymio développé à l’EPFL. Il est déployé en France dans les activités périscolaires des écoles de plusieurs villes, dont Lille, Talence et Lormont. Il a été développé par Didier Roy, Thomas Guitard et Pierre-Yves Oudeyer dans l’équipe Flowers, et est partagé sur le site participatif Dessine-moi un robot.

Art and Science

I collaborate regularly with artist within project that explore the frontiers between art and science. This has been the opportunity to create original connections between the general public and our scientific projects, in particular by bringing people to ask themselves and to ourselves stimulating questions about the position of such scientific projects within society at large.

Examples of such projects include:

Artistic residency “Etres et Numériques” (2014), a study of movement and emotions through the interaction between the humanoid robot Poppy and a dancer. This happened at Lycée Saintonge, in Bordeaux, and also included workshop with young students allowing them to discover various aspects of robotics and its role in society.#01- artistique | robotique | médiation – Recherche chien noir à tête d’ours, résidence Lycée Saintonge.

Poppy Project: Open-Source 3D printed Robotics Creation platform for Science, Education and Art

Poppy project is an open-source platform for the creation, use and sharing of interactive 3D printed robots. It was initially developed by the Flowers team at Inria, and is now supported by a large community of contributors and users. The new website of Poppy Project is out, and provides all links to hardware, software and documentation resources to build and/or obtain an open-source 3D printed Poppy robot, under the Creative Commons licence (CC-BY-SA). Poppy Humanoid was the first worldwide open-source 3D printed full body humanoid robot. Poppy Torso and Poppy Ergo are other robots that can be built and modified with the Poppy platform. The Poppy platform is used widely for projects in open science, open education from primary schools to university, and art.
