The robots have to collect trash while driving through a maze (2x3 meters) and and deliver the trash in a special color-coded area. They have about 40 entries of bots and the challenge goes on all week, so check it out if you're at the Systems. Unfortunately the robot challenge web pages are in german, but you can check the live webcams here." So either quickly learn German, or use the Fish. The current c't (print) magazine has great pictures of the competing robots, too.
