This is our end effector. Its 3 rollers. The two fiberglass folding arms that are sticking out at the bottom have been removed. Works like a charm and the top part of the rollers is used to push off balls. It was good enough for us to be undefeated in elimination rounds (until we faced 103 in the finals that is
). But overall, I love this thing. I would make it into a shooter though if we could do it all over again
