Great job guys!

ye it ended up being much simpler than the initial designs as we iterated. that roller was originally an entire conveyor belt system, but as we did some testing we noticed it was completely unnecessary so we ditched everything but the front roller. the external swinging fingers where going to be an entirely different system that would laso the game pieces but again through iteration and testing this system was also reduced to be as minimal as it is.

However, we did end up making one system much more complicated than original designs, and that was the flappers that drop down to grab the ledge of the totes to pick them up. We tried a passive approach initially like many other teams with bent poly-carbonate but weren't satisfied with stability of picking up a stack so this turned into a rather complex system we had to iterate on a few times and tweak to make work properly. There is a passive reset for them and we use servos(as you can see in the video if you look closely) to activate them. It's more complex than I would like but it seems to be working perfectly without any issue every single time so i'm not worried about it anymore.
