If you are interested in taking part in one of the Challenges at ICRA 2009, you should send email to the Challenge chair and to the chair of the event that you are interested in. You should also subscribe to the mailing lists to make sure that you get announcements as they come out.
Remember that the goal of the ICRA Robot Challenge is to showcase your research. If you're interesting in bringing your robot, but the listed events don't quite fit your research, then email us and let us know. There's probably a way that we can modify one of the events to make it fit better. Our main goal is to bring robots to ICRA and to demonstrate the state-of-the-art to the community.
