Extending above 60"

[Nemo]

I'm really looking forward to seeing a bit of a rock-paper-scissors game play out this year. It seems to me that a full court shooter sitting in its loading zone that can drain their alliance's frisbee supply into the top goal is going to dominate this game most of the time in qualifiers. But in elimination matches, they're going to get shut down if an opposing robot has the ability to extend their robot high enough to block those shots. If there's enough defense out there, then climbing looks good by comparison since it's hard to defend against.

So my question is, are there robots out there that have this capability to extend upwards for defensive purposes? It's a risk to build something like that, but I think those robots are going to get snapped up in alliance selections this year.
