A geometric optimal control approach for imitation and generalization of manipulation skills

Sylvain Calinon, Amirreza Razmjoo Fard, Jie Zhao

Daily manipulation tasks are characterized by regular features associated with the task structure, which can be described by multiple geometric primitives related to actions and object shapes. Only using Cartesian coordinate systems cannot fully represent ...

ManiGaze: a Dataset for Evaluating Remote Gaze Estimator in Object Manipulation Situations

Jean-Marc Odobez, Rémy Alain Siegfried, Bozorgmehr Aminian

Gaze estimation allows robots to better understand users and thus to more precisely meet their needs. In this paper, we are interested in gaze sensing for analyzing collaborative tasks and manipulation behaviors in human-robot interactions (HRI), which dif ...

A Dynamical System Approach for Adaptive Grasping, Navigation and Co-Manipulation with Humanoid Robots

Aude Billard, Salman Faraji, Nadia Barbara Figueroa Fernandez, Mikhail Koptev

In this paper, we present an integrated approach that provides compliant control of an iCub humanoid robot and adaptive reaching, grasping, navigating and co-manipulating capabilities. We use state-dependent dynamical systems (DS) to (i) coordinate and dri ...

Learning from demonstration for semi-autonomous teleoperation

Sylvain Calinon

Teleoperation in domains such as deep-sea or space often requires the completion of a set of recurrent tasks. We present a framework that uses a probabilistic approach to learn from demonstration models of manipulation tasks. We show how such a framework c ...

Automatic extraction of constraints in manipulation tasks for autonomy and interaction

Ana-Lucia Ureche

Tasks routinely executed by humans involve sequences of actions performed with high dexterity and coordination. Fully specifying these actions such that a robot could replicate the task is often difficult. Furthermore the uncertainties introduced by the us ...

Evaluation and Prediction of Evoked Emotions Induced by Image Manipulations

Touradj Ebrahimi, Lin Yuan

Various image editing tools make our pictures more attractive, and at the same time, evoke different emotional responses. With powerful and easy-to-use imaging applications, capturing, editing and then sharing pictures have become daily life for many. This ...

Climate change effects on the stability and chemistry of soil organic carbon pools in a subalpine grassland

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Bjorn Jozef Maria Robroek, Thomas Spiegelberger, Robert Thomas Edmund Mills

Mountain soils stock large quantities of carbon as particulate organic matter that may be highly vulnerable to climate change. To explore potential shifts in soil organic matter (SOM) form and stability under climate change (warming and reduced precipitati ...

The effects of spatial attention on temporal integration

Michael Herzog, Marc Michael Lauffs

Feature fusion reflects temporal integration. Previous studies mostly employed foveal presentations with no attention manipulation. In this study we examined the effects of sustained spatial attention on temporal integration using feature-fusion with perip ...

Single locus of control in a tangible paper-based tabletop application: An Exploratory Study

Pierre Dillenbourg, Luis Pablo Prieto Santos, Daniela Caballero Díaz, Yun Wen

Multiple loci of control is one of the main affordances of tangible tabletop UIs due to their capability for simultaneous manipulation. However, there is a tension between the efficiency given by simultaneous manipulation and the need to coordinate and ref ...

Towards comprehensive capture of human grasping and manipulation skills

Aude Billard, Sahar El Khoury, Ravin Luis De Souza, José Santos-Victor

Grasping plays a central role in our daily life. To interact with objects surrounding them, people use a large diversity of hand configurations in combination with forces ranging from the small ones involved in manipulating a pen for writing, to larger for ...

Nonlinear relaxation and selective polychromatic lasing of confined polaritons

Benoît Marie Joseph Deveaud, Gabriele Grosso, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol

Polaritons have often been proposed as promising candidates for the realization of all-optical devices due to the easy manipulation and control of their density and spin. In this paper we present a relaxation mechanism for confined polaritons and its appli ...

The learning of adjectives and nouns from affordance and appearance features

We study how a robot can link concepts represented by adjectives and nouns in language with its own sensorimotor interactions. Specifically, an iCub humanoid robot interacts with a group of objects using a repertoire of manipulation behaviors. The objects ...

Probabilistic Depth Image Registration incorporating Nonvisual Information

Aude Billard, Ludovic Righetti

In this paper, we derive a probabilistic registration algorithm for object modeling and tracking. In many robotics applications, such as manipulation tasks, nonvisual information about the movement of the object is available, which we will combine with the ...

A state-action neural network supervising navigation and manipulation behaviors for complex task reproduction

Aude Billard, Florent D'Halluin

In this abstract, we combine work from [Lagarde et al., 2010] and [Calinon et al., 2009] for learning and reproduction of, respectively, navigation tasks on a mobile robot and gestures with a robot arm. Both approaches build a sensory motor map under human ...

Microparticle photometry in a CMOS microsystem combining magnetic actuation and in-situ optical detection

Edoardo Charbon, Martinus Gijs, Ulrike Lehmann, Cristiano Niclass, Emile Dupont, Stefano Pietrocola

We present a hybrid CMOS-based microfluidic system that combines magnetic actuation of microparticles with in situ optical detection using single photon avalanche diodes (SPADs). The decoupling of the principles used for actuation and sensing permits a hig ...

What is the Teacher's Role in Robot Programming by Demonstration? - Toward Benchmarks for Improved Learning

Aude Billard, Sylvain Calinon

Robot programming by demonstration (RPD) covers methods by which a robot learns new skills through human guidance. We present an interactive, multimodal RPD framework using active teaching methods that places the human teacher in the robot's learning loop. ...
