See inside Amazon’s robot warehouse

At Amazon’s sprawling fulfillment center in Tracy, California, robots carry shelves, sort packages, and move carts toward delivery trucks.

But this is not a fully automated operation.

Thousands of people still work alongside the machines, picking and packing orders, loading trailers, clearing jams, handling damaged items — and stepping in when the automated system hits a problem it cannot solve.

Business Insider toured the facility recently to see how warehouse work is changing as Amazon deploys more robotics technology.

These photos and videos show how people and robots work side by side, offering a glimpse of a more autonomous future.

This is the latest installment of Robonomics, Business Insider’s series on the rise of robots and their impact on business, jobs, and everyday life. We’ve unpacked the investment boom in robotics and spoken to Amazon warehouse workers to see if machines were taking their jobs.

This is the entrance to Amazon’s robotics fulfillment center in Tracy, California.

Workers and visitors pass through security gates before entering.

The Tracy warehouse spans 1.4 million square feet, roughly the size of 23 football fields.

Amazon says its next-generation fulfillment centers are about 25% more productive, and support roughly 30% more skilled jobs.

At Tracy, employees stow items in fabric pods that Hercules robots carry to pick stations.

This is Robin, a robotic arm that picks finished packages from a conveyor.

The packages are then placed on Pegasus mobile robots.

The Cardinal robotic arm then loads the sorted packages into tall metal carts.

Proteus, a mobile robot, then carries the carts toward outbound trucks. Loading trucks still remains manual work, with employees arranging packages to make the most of the available trailer space.

Human process assistants oversee warehouse robotic systems, coordinating responses when a chute jams or a robot stops working.

Briana Brager joined Amazon about two years ago as an entry-level employee. Now, she’s a process assistant who monitors the machines and responds when something goes wrong.

When a Proteus robot breaks down, it is sent to this diagnostic center for inspection and repair.

Another area of the warehouse is called “Jackpot,” where the automated system sends packages that get lost. A human worker determines where each wayward package belongs and returns it to the correct flow.

Mohammed Khan started as an entry-level picker 12 years ago and is now a senior manager at the warehouse. He said robots streamline work without necessarily eliminating it. “It’s not that the amount of work has changed, it’s how we approach it.”
