PR2 Workshop 2012 – Roundup

The week-long PR2 Workshop in Freiburg was a success!

Approximately 40 people participated in the workshop, which primarily consisted of a hackathon. Participants were divided into six teams with people from multiple different institutions. Teams tackled a variety of problems related to the ICRA sushi challenge (coming to ICRA this year!).

The sushi challenge presents a number of interesting and tricky problems. A comprehensive solution would have to deal with a multitude of uncertainties. Here are a few of the challenges that the teams at the workshop focused on:

  • – How to avoid collisions and determine grasps for objects on a moving platter
  • – How to stack objects when clearing away a table
  • – How to detect reflective or opaque objects, such as metal cutlery
  • – How to unstack objects from stacks, such as cups and plates
  • – How to lay a table
  • Check out the video of Stephen’s team’s achievements:

    The forthcoming wrapup from Willow Garage will provide a comprehensive overview of all that was achieved. Watch this space!

    Below are a few photos from the hackathon. Check out our flickr album for even more!

    PR2 Workshop 2012 – Dish Stacking

    This week, most of the group is in Freiburg, Germany for the PR2 Workshop, graciously hosted by Wolfram Burgard’s group. This workshop is mostly a hackathon for the ICRA 2012 Sushi Boat Mobile Manipulation Challenge. Participant from various research groups were split into six teams to explore different approaches and aspects of the challenge, with people from Brown Robotics on five of these teams. Stephen’s group had a nice dish stacking demo working by the end of the second day.

    However, Stephen might be more famous for this video:
