Hello @CsabaAbanJr
in Rescue Line 2025 rules
4.4.6 . Team members may compete in Rescue Line twice (2 international events). After competing in Rescue Line twice, they must move to another RoboCupJunior sub-league.
so, It is not necessary to move to Rescue Maze; they can move to other categories of RoboCupJunior, such as Rescue Simulation, Soccer, or OnStage.
Of course, they can also move to Rescue Maze.
(find it under this link: RCJ Rescue Line - RoboCupJunior )
I think the information on this link is outdated.
I hope the information will be updated correctly.
Best Regards
MASA
