Update 2 discusses the door. Basically it says, "if you engineer a reliable method to ensure that the door is open, then you don't have to rely on hope."
2 – DOOR SWING
The
door’s tendency to stay still, open, closed, is random, based on tiny
variations in how the volunteers attach it to the west wall. Their
job is to make it like the picture – which “looks” level. When the
robot pushes the handle down, the door is designed to be
swingable,
and yes, it’s sensitive. Instead of hoping for a door that swings
open, or expecting the volunteers to attach it the way you want
it, the engineering solution to this mission is to figure out a way to
ensure that any door will be open at the end of the match, no matter how it might like to swing. (Insight and strategy advice)
Volunteers will set up the tables to make the door look vertical, but there are plenty of things that could encourage an open door to swing one or the other, both allowable (robot action) and not allowable (an arm bumping the table).
The score for the mission is based on the condition of the table at the moment that the match ends. If the door is closed at the end of the match, your team might be surprised that it has closed on its own, but they shouldn't be surprised by a score of zero for the mission. Update 2 has offered teams plenty of time to think about strategies.
