I've seen both on our team and discussion here on ChiefDelphi teams considering multi-functional arm units. I'd just like to remind teams of rule <G45> this year:

<G45> Active BALL control - ROBOTS may not control BALL direction with active MECHANISMS above the BUMPER ZONE. Violation: PENALTY.

This means any arm, hanging device, self-righting mechanism, monkey, etc. that is above the bumper zone may not be able to be used to block an opposing robot's shots (something that needs to be checked with the Q&A). This might constitute changing BALL direction and could incur a penalty. Feel free to park in front of an opposing goal with your robot though and already cover enough with your frame to prevent any shots from going above you.

By the way, this could give teams that can actually pop a ball in the air a major advantage, since teams can only passively block if their robot is tall enough (and the taller they are, the harder they fall...).
