Going off SG6
and my previous Q&A
It sounds like there is no legal way to lift opposing mobile goals off the tiles. However, it seems to be completely legal to slide them around on the tiles in any way.
Is it legal to hoard (gather and protect) the opposing mobile goals with a corral-like robot that surrounds them but does not lift them off the tiles?
For example: (red is robot, blue is mobile goal, nothing is beneath the mobile goal other than the field tiles)
Since we can push the goals with concave surfaces it seems pretty clear that this is legal, but I just want to make sure.
