IROS 2011: The PR2 Workshop


The PR2 Workshop:
Results, Challenges and Lessons Learned in Advancing Robots with a Common Platform

(At IROS 2011)

Abstract

In recent years, the use of common software and hardware platforms has played a big role in focusing and advancing the state of the art in areas like legged locomotion (the Littledog program), rough terrain navigation (the LAGR program) and robot soccer (RoboCup). To this end, over the last few years, Willow Garage has been engaged in an effort to build a community around a common software platform (ROS) and a common mobile manipulation platform (the PR2 robot). This full-day workshop is intended to present results, challenges and lessons learnt from this international effort using the PR2 as a common platform for robotics research. The workshop will serve to showcase the impressive research in manipulation, perception, navigation, mapping, HRI, controls and other areas conducted with the PR2 robot. Live demonstrations by the presenters will allow the audience to view cutting edge research in action. The research results and tools presented in this workshop have found wider use in the robotics research community and will be of interest to the entire conference audience. The workshop will conclude with a discussion on the challenges and lessons learned in effective collaboration and sharing for robotics research with a common platform.

Presenters

The presenters at this workshop will be members of the robotics community who are working with the PR2 robot, either in simulation or on the actual hardware. The physical PR2 robot is currently available to approximately 20 sites around the world, while the simulator for the PR2 robot is based on the open-source Gazebo software and is potentially available to the entire robotics research community.

The only thematic requirement for work to be presented at the workshop is that it must be done on, or highly relevant to, the PR2 platform. Submissions will be reviewed for technical merit and fit with the theme of the workshop. All participants will be encouraged to provide a live demonstration of their work on the PR2 platform.

Call For Papers

Submissions should consist of an extended abstract (2 pages) and a video of the PR2 (real or simulated) in action. Work may have been previously published. Accepted authors should be ready to demo (if appropriate) at the workshop. Willow Garage will provide PR2s for the workshop, and time beforehand to make sure the demos run smoothly.

Extended abstracts should use the standard IROS paper submission template (removing the "Abstract" section.) Submissions are not double blind, please include all of the authors' names and institutions.

Videos should be a maximum of 5 minutes long. Please compress videos as much as possible, do not use full HD format.

Submissions should be emailed to pantofaru AT willowgarage DOT com. If the video is too large for email, contact us and we'll find another solution.

Motivation and Objectives

The goal of this workshop is to bring together the growing community of PR2 users, both those with physical PR2 robots and those doing work in simulation, to present technical work, see what others in the community are working on, and form lasting collaborations.  Approximately 20 sites now have a physical PR2, and several more are working with the PR2 in simulation. Technical papers centered around the PR2 have appeared in major conferences such as IROS and ICRA. This workshop will provide a common venue for dissemination of results from the PR2 research community showcasing cutting edge research in multiple areas that will be of interest to a large number of conference attendees.

Willow Garage will supply PR2 robots for the workshop on which participants can demonstrate their work.  We will work with participants beforehand to ensure that the demonstrations run on the provided robots.
