Since there were two different answers to this question: the organizers will
provide robot numbers to the teams. However, they will not provide an
unlimited number of stickers to the teams, so please be careful with them.

Actually, they mostly are. The defending team is allowed scoring a goal from
within the center circle, the attacking team is not (before the ball left
the center circle at least once). However, the new rules allow the attacking
team to be much closer to ball than the defending team. So the attacking
team can expect that their robot will be the first at the ball, so it can,
e.g., pass it to a teammate outside the center circle, before any defending
robot can interfere (if the attacking team is not too slow).
