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).
