Automatic extraction of constraints in manipulation tasks for autonomy and interaction

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 ...

Open Robotics Research Using Web-based Knowledge Services

Aude Billard, Nadia Barbara Figueroa Fernandez, Ana-Lucia Ureche, Zhou Fang

In this paper we discuss how the combination of modern technologies in "big data" storage and management, knowledge representation and processing, cloud-based computation, and web technology can help the robotics community to establish and strengthen an op ...

Learning Complex Sequential Tasks from Demonstration: A Pizza Dough Rolling Case Study

Aude Billard, Nadia Barbara Figueroa Fernandez, Ana-Lucia Ureche

This paper introduces a hierarchical framework that is capable of learning complex sequential tasks from human demonstrations through kinesthetic teaching, with minimal human intervention. Via an automatic task segmentation and action primitive discovery a ...

Task Parameterization Using Continuous Constraints Extracted From Human Demonstrations

Aude Billard, Ana-Lucia Ureche

In this work we propose an approach for learning task specifications automatically, by observing human demonstrations. Using this allows a robot to combine representations of individual actions to achieve a high-level goal. We hypothesize that task specifi ...

Assessing Interaction Dynamics in the Context of Robot Programming by Demonstration

Aude Billard, Brenna Dee Argall, Ana-Lucia Ureche

In this paper we focus on human-robot interaction particularities that occur during programming by demonstration. Understanding what makes the interaction rewarding and keeps the user engaged helps optimize the robot's learning. Two user studies are presen ...
