I saw something about one of these amazon warehouses that has robots to do the fetching. The robots would drive out in an optimal route to pick up several bins then return to a station where a human would pick the correct items out of the bins and box them up.
It struck me as rather dystopian in that the humans were basically pick/place robots, and their only useful attribute was the ability to recognize objects and determine the correct size of box to put them in.
Given 100+ warehouses built over years handling various types of goods they presumably have more and less automated warehouses.
