Amazon Proteus
The most autonomous AMR in the warehouse, and the only one you can’t buy.
Why this verdict · Updated July 2026
We rate it REAL and, moreover, fully autonomous. Unlike collaborative AMRs, Proteus needs no human in the loop: it plans its routes, dodges obstacles dynamically and works outside caged zones, alongside workers. It holds SIL 2 safety certification and runs in 24 Amazon centers. The honest nuance isn’t about its autonomy, that’s genuine, but about access: it isn’t sold. It’s an internal Amazon product, not a purchase you can make.
What it does well
- Real full autonomy: no human in the loop and no safety cages
- Works among people with SIL 2 safety certification
- Deployed and in production across 24 centers
- New version (2026) that takes plain-language commands
What it doesn’t
- Not for sale: exclusive to Amazon
- Specialized in cart transport, not picking
- Amazon doesn’t publish full specs or a price

Why Proteus is a milestone (and why you can’t buy it)
Most warehouse robots either follow guides, work in zones separated from people, or rely on a human for the fine decisions. Proteus breaks all three limits: it’s a load AMR that moves freely through the warehouse, dodges people in real time and needs no cages or constant supervision. That’s why Amazon calls it its first 'fully autonomous' robot.
The detail that defines its page is commercial, not technical: Amazon doesn’t sell it. Proteus is built for Amazon’s own network, which already tops 750,000 robots. For an outside buyer it’s a reference for where the sector is heading, not a catalog option.
The lineage: from Kiva’s caged robots to the free-roaming Proteus
Proteus is the end (so far) of a line that began in 2012, when Amazon bought Kiva Systems and kept its shelf robots for itself. Those Kivas, and their direct descendants, worked caged: fenced zones no human could enter while the robots moved, because their navigation depended on a grid of floor codes and they couldn’t react to a person. For a decade, Amazon’s automation grew inside those cages past 750,000 robots.
Unveiled in June 2022, Proteus was the first to leave the cage: onboard perception, dynamic avoidance and certification to work in the same aisles as people. That leap (from code grid to open world) is the same AGV-to-AMR transition the rest of the industry is living, executed by the company with more warehouse data than anyone on Earth. That’s why its page matters even though it isn’t sold: Proteus is the yardstick for what a load AMR should become.

Frequently asked
Is the Amazon Proteus fully autonomous?
Yes. It plans its routes and avoids obstacles on its own, works among people without cages and holds SIL 2 safety certification. It’s Amazon’s first mobile robot with full autonomy.
Can I buy an Amazon Proteus for my warehouse?
No. Proteus is Amazon-internal and isn’t sold. For similar autonomy on the market, see other makers’ load AMRs in our comparison.
Where is Proteus used?
In Amazon’s fulfillment network: it runs in 24 US sites, with a 2026 version that takes natural-language instructions.
How is Proteus related to the Kiva robots?
It’s their direct descendant. The Kivas Amazon bought in 2012 navigated on floor codes and worked in fenced zones; Proteus, unveiled in 2022, is the first generation that navigates freely and shares aisles with people.
