Proteus is Amazon's first fully autonomous mobile robot: a low-slung AMR that slides under package carts (GoCarts) and moves them through open areas of fulfillment and sort centers without caged-off zones. Built by Amazon Robotics, it runs in 25 US fulfillment centers as of mid-2026, and a next-generation version unveiled in June 2026 accepts plain spoken instructions. It is an internal Amazon system and cannot be purchased.

Our take
Proteus matters less as a product and more as a signal: it defines the state of the art in free-roaming warehouse AMRs and shows where the industry's largest robot fleet (1M+ units, coordinated by the DeepFleet AI model) is heading. Warehouse operators can't buy it, but should benchmark vendors against its capabilities — full autonomy among people and, from 2026, natural-language tasking. Its European rollout in 2027 will pressure every AMR vendor's roadmap.
Best suited for
- Outbound GoCart transport in fulfillment and sort centers
- Cart moves through open, human-occupied floor areas without safety cages
- Ad-hoc material moves directed by spoken instructions (next-gen)
Proteus: common questions
Can you buy Amazon's Proteus robot?
No. Proteus is built by Amazon Robotics exclusively for Amazon's own fulfillment and sort centers and has never been offered for sale to other companies.
What does the Proteus robot do?
It autonomously lifts and moves GoCarts — wheeled package carts loaded with up to 800 lb — through open areas of Amazon warehouses, navigating safely around employees without caged robot zones.
Is Proteus fully autonomous?
Yes. Amazon calls Proteus its first fully autonomous mobile robot; it uses onboard perception to move freely around people, and the next-generation version announced in June 2026 can act on plain-language spoken instructions.
How widely is Proteus deployed?
As of mid-2026 Proteus operates in 25 US fulfillment centers, with the next-generation version planned to reach Amazon's European operations in the first half of 2027.
How is Proteus different from Amazon's Kiva-style drive units?
Kiva-derived drive units work inside fenced-off zones carrying inventory pods; Proteus is designed to work in open, human-occupied areas, which is why Amazon brands it as its first 'fully autonomous' mobile robot.
