Personally, I think that using suction cups will prove promising on the totes. It wouldn't matter if a tote was upside down or right side up. But I foresee them being more difficult on the bins, because they are curved and somewhat flexible. With all that in mind, creating a bot that uses suction cups would easily win you the Xerox Creativity Award. It is one of those things that few teams would see to fruition.
