Re: My Hopper/Dumper Idea
 

I've been struggling with this all day for clarification. As you say the rules are very vague, however, I just replayed the animation, and 2:15 they mention the that

"near the end of the match human players can throw discs onto the field and try to score. At the same time, robots drive to their pyramids and start to climb for bonus points"

The rules do spell out in 3.2.7.2 G35 that

"Discs may be fed onto the feild only under the following circumstances:

A. During TELEOP through the feeder slots and
B. during the last thirty (30) seconds of TELEOP over the FEEDER
STATIONS."

I would infer from this that this is the "same time" that they mention in the animation, and therefore the climbing period would be during the last 30 seconds. It would be nice if they provided a little more detail on the climbing.

I suspect we'll see some clarification on this soon.

I agree, I think we will see some clarification. Though the rules as of right now don't say a thing about climbing being specifically the end game. And we all know how often the animation breaks game rules.
