Robuddies Reading Group

This is the web page of the LCI reading group Robuddies.

Robuddies meets Mondays at 2:00pm (for Fall 2013) in ICCS146

The topics for robuddies are Robotics and Computer Vision. Each week someone presents a paper/tutorial or their current research, or some mix of these. To subscribe to the mailing list for talk announcements, send a message to "majordomo[at]cs.ubc.ca" with the words "subscribe robuddies-seminars" in the body.

A schedule of upcoming papers can be found below under the heading Upcoming Papers. Under the heading Finished Papers is a log of earlier topics. If you want to be added to the schedule, please contact the Robuddies Czar, who currently happens to be Junaed Sattar (junaed AT cs ubc ca).

Note that robuddies-seminars is a moderated mailing list so non-members cannot mail to it. Contact the Czar if you wish to do so and are not a member.
