It would be hard to move them if they brace themselves against the wall and the side and that corner. You really can't push them from the other side and most robots can't pull as well as they push. Anyway what could you grab onto to pull. That would just get you in trouble. My next move would be if they have a fabric to capture the balls to strategically push on that kind of like when a baseball gets caught on top of mesh batting cages. This would possibly divert the flow of the balls.
