I don't know what others would do, but if an opposing robot collects all the balls (and I literally mean all the balls), I'm sticking one robot in front of them at all times to prevent them getting near a corner goal. With no balls to score, the other team will have nothing to do but stop you from scoring, which gives you very little chance of doing it.

Of course, with a big enough lead this is fine, because then you can just sit there and let the match end and it won't matter if the blocking robot's 2 partners get on the ramp.
