content: I was really surprised about that too. I used to be in a warehouse where robots controlled 29 000 pallets and the robots were basically just fork lifts on a rail. Rails were really long, 11 pallets on top of each other. Pallets are of course big but there was a smaller automated storage too where you ordered a plastic box full of items from a numbered shelf and the plastic box came to the collection spot in less than ten seconds or so. Moving the shelfs like in the video looks slow to me and if the robots get messed up, what a job to get the shelfs in order again!
