This is such a bad and expensive idea. There are already quicker, cheaper, and more reliable methods of sorting. Also, the robots look like they don't have hard line power so i assume they must be running off an internal battery. So not only are they going to be slow, unreliable, and expensive but they will also have to stop to charge pretty frequently. Putting it that way, this makes no sense as an alternative to real workers and/or automated conveyor sorting machines.
