Im not so sure about this talk of tipping the ladder. So is it legal to tip the ladder if it does not damage any feild elements??? if this is true, woun’t it ruin most strategies? such as 44’s bases in the ladder, or even any robot that wants to hang, or putting tubes in the ladder. Is it legal to tip the ladder? 
It is legal to lift the ladder. It is not legal to tip the ladder over, such that it is on laying on the ground. However, teams who lift the ladder are responsible for any damage the lifting may cause, either by the ladder being dropped on a robot, or making robots fall off the ladder.
Thanks. That makes sense.
