Robuddies Reading Group

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

Robuddies meets Fridays at 11:00am 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 David Meger (dpmeger AT cs ubc ca).
