scaling the castle

[New Lightning]

Not sure on the actual rule number just that they have to remain there for enough time for the refs to know for sure that your robot has in fact climbed the tower. I.E. it is clear enough that your robot has indeed gotten its bumbers above the low goal.

At the end of 3.3.1 the rulebook says:

While it is not strictly required that the robot stay above the low goals for five seconds after the end of the match, this is probably a good design goal to eliminate any uncertainty in when the refs happen to notice that your robot has come to rest or not.

one could argue it has not come to rest if it is slowly creeping down

5 seconds, or rest, whichever comes first. If you aren't sure whether you want the refs to make a judgment call, bear in mind that the refs seem to be being instructed NOT to give the teams the benefit of the doubt, and plan accordingly.

If you're sliding down the tower 5 seconds after the end of the match, but it's still above the low goal, you're good.
