Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Towards Real-Time Sensor-Based Path Planning in Highly Dynamic Environments

Roland Siegwart, Björn Jensen, Roland Philippsen

This paper presents work on sensor-based motion planning in initially unknown dynamic environments. Motion detection and probabilistic motion modeling are combined with a smooth navigation function to perform on-line path planning and replanning in clutter ...

Robots Meet Humans Interaction in Public Spaces

Roland Siegwart, Nicola Tomatis, Björn Jensen

This paper presents experiences from Robotics, a long-term project at the Swiss National Exposition Expo.02, where mobile robots served as tour guides. It includes a description of the design and implementation of the robot and addresses reliability and sa ...

2005

This thesis aims at improving the perceptional side of interaction to enable the handling of more complex situations. For the Swiss National Exposition Expo.02 the robot RoboX and an event-driven interaction system have been designed by members of our lab. ...

Multi-Robot Human-Interation and Visitor Flow Management

Roland Siegwart, Björn Jensen, Guy Ramel

In this paper we address the task of human-robot interaction in public mass exposition with several autonomous robots at a time. This implies questions regarding multi-robot control and interaction management with respect to social and commercial aspects o ...

Motion Detection and Path Planning in Dynamic Environments

Roland Siegwart, Björn Jensen, Roland Philippsen

Motion detection from mobile platforms is a challenging task. It requires precise position information, which is difficult in cluttered dynamic environments. We combine motion detection and position estimation using Expectation Maximization. To reduce the ...

Design, Implementation and Exploitation of a New Fully Autonomous Tour Guide Robot

Roland Siegwart, Nicola Tomatis, Björn Jensen, Kai Oliver Arras, Roland Philippsen

This paper presents the genesis of a tour guide robot, which has been built from the scratch based on the experience of the Autonomous Systems Lab. The production of 11 of those machines has been realized by a spin-off of the lab: BlueBotics SA. The goal w ...
