Thanks for the feedback. We do not have a collector on the back because our winch mechanism sits up high and we wouldn’t be able to get a ball over it. We also liked the idea of being able to face the same direction for collecting and shooting because it seems to be easier to line up a shot.
We actually were able to catch a few during our scrimmage from other robots. It wasn’t real high on our list but if the opportunity arises we will certainly try. We have also entertained adding some more angled shields to the back side of the collector arms so that they can help catch better. If we are facing the goal with our arms down we have a pretty large catching zone.
