How effective would it be to have a robot place tetras (either randomly or strategically) on the field to block the opposing robots. This would probably involve quite a bit of driving between the opponents side and a loading station. The tetras themselves don't present much of an obstacle by themselves, but three/four of them in close proximity to a goal could have the potential to force the opposing teams to push/drive around the extraneous tetras.

Any thoughts?
