But the system is actually nothing new.
Amazon has been using the robots, originally developed by Kiva Systems, in the U.S. since 2014, Retuers reported.
The company installed the system before 2014's holiday season to help push more of its stock out the door and into the hands of anxious Christmas shoppers.
It came to be after a shipping nightmare in late 2013. That's when too many packages from Amazon flooded UPS, causing world-wide shipping delays. Amazon ended up having to issue shipping refunds and $20 gift cards in compensation to upset customers, Reuters reported.
The robots proved to be a success, holding at least 50 percent more products than the traditional sorting system, and shortening time for same-day delivery.
So how does it work?
Instead of workers having to walk down long lines of shelving looking for something, the robots bring the items to the works who pick out what they need and put the product in bins, the BBC reported.
