One of the nice things about the Kiva robots is that they will actually organize the warehouse based on popularity of the SKUs automagically. Things that are low volume get placed farther away from the pickers, and things that are high volume are never far away from the pickers.

Another advantage of the Kiva system is that they are not picky about the types of items that can be stored. They can store and move just about anything that fits on a shelf. Shuttle systems have some restrictions about the types of items that can be stored. Amazon has such a wide range of items that the flexibility of their shelving units allows them to get the most advantage out of their goods-to-person robots.

I agree that is an advantage of the goods-to-person robots but shuttle systems do the same thing and are a better use of vertical space.

What's an example of them? I'm interested to learn.
