What is the hardest (yet possible) task in this year's game?

[KenWittlief]

As the weeks go by and the physics of the game sinks in, I think the real magic trick is going to be finding a way to guard or block the center goal, parked infront of it (not chasing robots around to block their shots).

I notice the rules say you cannot extend in a 'stable configuration' above a certain height - does that mean you could take swipes at a ball in flight, if your flailing arms are not 'stable' ?

Could you have a bot with a big sticky tongue that shoots out and snatches balls out of the air, like flys?

Maximum Height - A ROBOT may not extend above 60” above the floor or the ALLIANCE PLATFORM in a stable configuration at any time during a match...
