Their sales pitch seems to be roughly that the value is more in the machine learning software than the gripper itself. I assume having both means the software can choose how much of each (fingers/suction) to use for a particular item, after it identifies the item.
So perhaps it's supposed to work best when there's a variety of items versus a few predictable ones.
while certainly cool, i have always found such robots disturbing because instead of being used to sort recycling or some other useful purpose, they are meant to actually increase the disposal of plastic and other such waste by moving product at ever increasing rates.
