First, all the qualification-related deadlines are now online: https://ssl.robocup.org/robocup-2019-qualification/. The registration dates have not been set yet. We will keep you up to date.
Second, instead of oral ETDP presentations, every division A team must (and every division B team may) bring along a poster that illustrates the content of the paper. The poster must have a size of roughly one square meter (A0) and will be hung up in the RoboCup venue. Posters allow every participant to learn about other teams’ ideas at any given time during the RoboCup, for example during lunch breaks, without having to sacrifice a lot of time.
