Amazon Robotics LLC is the wholly owned robotics and warehouse-automation subsidiary of Amazon, headquartered at 300 Riverpark Drive in North Reading, Massachusetts, with major facilities in Westborough, Massachusetts and a research presence in Berlin, Germany and Sumner, Washington. The company designs, manufactures, and operates the autonomous mobile robots, robotic arms, gantry systems, and software that run inside Amazon's global fulfillment and sortation network. It was founded in 2003 in Boston as Kiva Systems by Mick Mountz, Peter Wurman, and Raffaello D'Andrea, acquired by Amazon on March 19, 2012 for about $775 million in cash, and rebranded as Amazon Robotics in August 2015.
In July 2025 Amazon announced it had deployed its one millionth robot across more than 300 fulfillment and sortation buildings, alongside the launch of DeepFleet, a generative AI foundation model that coordinates the movement of those robots. By that milestone the company operated what Amazon and outside analysts describe as the largest fleet of mobile warehouse robots on Earth. The fleet is also the most consequential argument for the modern wave of warehouse automation, because every Amazon competitor has had to react to it.
Kiva Systems was founded in January 2003 by Mick Mountz, an MIT-trained engineer who had worked on the business process team at the failed grocery-delivery startup Webvan. Mountz had concluded that the inflexibility of conventional conveyor-and-rack material handling, with humans walking miles per shift to fetch products from fixed shelves, was a major reason Webvan's economics never worked. He partnered with Peter Wurman, a multi-agent systems researcher, and Raffaello D'Andrea, a control-theory roboticist then at Cornell University and later a professor at ETH Zurich and a co-founder of Verity. The trio inverted the traditional warehouse model: instead of a person walking to inventory, a fleet of squat orange drive units would slide under stacked shelves, lift them, and ferry the entire shelf to a stationary picker.
Kiva's first commercial deployment was at Staples in 2006, followed by Walgreens, Gap, Office Depot, Crate & Barrel, Saks Fifth Avenue, Gilt Groupe, and the shoe retailer Zappos. Zappos was acquired by Amazon in 2009, which gave Amazon's operations teams direct exposure to Kiva drives running at scale. By 2011 Kiva was the most visible name in goods-to-person robotics and was negotiating to expand its customer base.
On March 19, 2012, Amazon announced it would acquire Kiva for approximately $775 million in cash. It was Amazon's second-largest acquisition at that point, behind only Zappos itself. The deal closed in the second quarter of 2012. Almost immediately Amazon began the controversial step of winding down Kiva's external customer relationships, which left other large retailers scrambling to find substitute systems. That decision is widely credited as the trigger event for an entire crop of new warehouse-robotics startups, including Locus Robotics, 6 River Systems, Fetch Robotics, GreyOrange, and ultimately Symbotic's relationship with Walmart.
In August 2015 the subsidiary officially renamed itself Kiva Systems LLC to Amazon Robotics LLC and began consolidating its Massachusetts footprint. A new 350,000-square-foot manufacturing and R&D campus opened in Westborough in October 2021, adding more than 200 manufacturing jobs and joining the original North Reading headquarters. Amazon Robotics also operates an Innovation Lab in Seattle, the Berlin Robotics Center in Germany, and a research and pilot facility in Sumner, Washington that is used for trials of next-generation hardware including humanoid platforms.
Amazon Robotics builds machines along three main axes: drive units that move pods or carts (the Kiva-derived line), robotic arms that pick and sort packages, and integrated storage-and-retrieval systems that combine the two. New machines are typically introduced at Amazon's annual Delivering the Future conference in Boston (and, since 2024, in Dortmund, Germany).
| Robot | Year introduced | Type | What it does |
|---|---|---|---|
| Kiva drive unit (orange) | 2006 (pre-acquisition) | Drive unit | Original goods-to-person AGV; slides under shelves and lifts up to 1,000 lb |
| Hercules | 2016 (deployed) | Drive unit | Heavier-payload version of the Kiva drive, lifts up to 1,250 lb pods, navigates with 3D camera |
| Titan | 2017 | Drive unit | Heavy-duty drive, lifts roughly twice as much as Hercules, used for bulky and oversized items |
| Pegasus | June 2019 | Conveyor-on-wheels | Sortation drive with a small belt on top; carries individual packages to chute openings, improved sort accuracy by about 50 percent |
| Xanthus | June 2019 | Drive platform | Thinner, modular successor base used to build many later drive variants; one-third the parts of original Kiva |
| Robin | 2021 | Robotic arm | Vision-based arm that picks shipped packages off conveyors and places them on Pegasus drives |
| Bert and Ernie | 2021 (prototypes) | AMR / arm | Bert is an autonomous mobile robot that ferries items; Ernie removes totes from shelving at safer ergonomic heights |
| Scooter | 2021 (prototype) | Drive unit | Pulls strings of GoCart wheeled carts through fulfillment centers |
| Proteus | June 2022 | Autonomous mobile robot | Amazon's first fully autonomous AMR, certified to operate in shared space with humans without floor barcodes; moves GoCarts in outbound areas |
| Cardinal | June 2022 | Robotic workcell | Picks individual packages weighing up to 50 lb out of a pile, reads the label, and places them in a GoCart |
| Sparrow | November 2022 | Vision-based picking arm | Picks individual customer items out of inventory totes; latest versions identify more than 200 million unique products |
| Sequoia | October 2023 | Containerized storage and retrieval system | Combines mobile robots, gantry systems, and arms to consolidate inventory in totes; identifies and stores inventory up to 75 percent faster |
| Vulcan | May 2025 | Pick-and-stow arm with tactile sensing | First Amazon robot with a sense of touch via force feedback; reaches the highest and lowest shelves in storage pods, handles roughly three quarters of stored item types |
The Kiva drive remains the workhorse of the fleet, with later variants such as Hercules and the Xanthus-platform descendants making up most of the more than one million units in the field. Sparrow and Vulcan represent the harder problem of picking and stowing individual items, which historically resisted automation because Amazon's catalog contains an enormous variety of shapes, sizes, weights, and packaging materials. Sparrow handles inventory totes; Cardinal handles outbound packages; Robin handles arriving labelled packages on conveyors. Sequoia is the integrated system that strings several of these together inside a single building, and was first deployed at the Houston BHM1 fulfillment center in October 2023 before being scaled out at the next-generation facility in Shreveport, Louisiana in 2024, where Sequoia holds more than 30 million items, about five times the original deployment.
Amazon's published robot deployment numbers tracked roughly as follows.
| Year | Approximate fleet size | Notes |
|---|---|---|
| 2014 | ~15,000 | Two years after the Kiva deal |
| 2017 | ~100,000 | Disclosed in Amazon's annual letter |
| 2019 | ~200,000 | Stated by Amazon in June 2019 |
| 2021 | ~350,000 | Per Amazon and Modern Materials Handling reporting |
| 2023 | ~750,000 | Internal tracker shared with Distribution Strategy Group |
| July 2025 | 1,000,000+ | Announced alongside DeepFleet |
The million-robot fleet is spread across more than 300 Amazon fulfillment centers, sortation centers, and delivery stations worldwide. Amazon Robotics also operates a global manufacturing footprint to keep up; Westborough produces drive units for North America, and contract partners build Sparrow and Cardinal cells.
Amazon Robotics relies heavily on machine learning and modern AI for both perception and coordination. The biggest publicly disclosed pieces of the stack are:
Amazon has also said it expects to use Amazon Bedrock hosted foundation models to support natural-language operator interfaces and richer robot perception, although the deployed pipelines for Sparrow and Vulcan are largely Amazon-internal models.
Amazon's public position is that robots augment its human workforce rather than replace it. The company has repeatedly noted that hourly headcount in fulfillment has continued to grow since the Kiva acquisition, and it points to programs like Career Choice, the Apprenticeship program for robotics technicians, and an upskilling pledge to invest more than $1.2 billion to retrain 300,000 employees by 2025 as evidence that automation creates new technical roles, not just job displacement. New roles include flow control specialists, robotics floor monitors, reliability and maintenance engineering technicians, and robotic systems mechanics.
That picture is contested. Investigations by The New York Times, Reuters, The Atlantic, and others have documented that injury rates at Amazon warehouses, especially robot-equipped sortable fulfillment centers, run higher than at non-Amazon warehouses. The Strategic Organizing Center, a union-backed coalition, reported that the serious-injury rate at Amazon's robot-equipped sortable facilities reached 7.3 per 100 workers in 2021, about 28 percent higher than the rate at non-robotic Amazon sortable facilities, and roughly double the broader warehouse industry rate. Critics argue that automation enables faster pace-of-work targets that strain workers, while Amazon counters that newer robots like Sequoia and Vulcan are explicitly designed to remove ergonomically taxing reaches and bends. The injury debate is ongoing and is one of the most-watched labor stories in U.S. logistics.
Amazon's $1 billion Industrial Innovation Fund, launched in April 2022, has been the main vehicle for backing outside robotics startups whose technology might eventually plug into Amazon Robotics. Public investments and pilots include:

Amazon Robotics sits in the middle of a wider warehouse-automation industry, but its model (in-house technology used only by its parent) is unusual. Most other major players sell to third-party retailers and grocers.

Symbotic in particular has emerged as the closest peer, in the sense that Walmart effectively rebuilt its automated regional distribution centers around Symbotic systems and then sold its in-house robotics group to Symbotic in 2024 for $200 million plus a $520 million development commitment. This is the most direct case of a major retailer making the same in-house bet that Amazon made in 2012, just twelve years later and via a publicly traded partner.
Amazon Robotics' near-term roadmap, as disclosed by VP Scott Dresser and through amazon.science publications, involves three big themes:
A related but separate Amazon program, Prime Air, has been working on autonomous delivery drones since 2013. Prime Air sits inside Amazon's transportation organization rather than Amazon Robotics, although the two groups share talent on perception and motion planning.
Amazon Robotics did not invent warehouse automation, but it did three things that reshaped the industry:
First, it proved that goods-to-person mobile robotics worked at the largest possible scale. Kiva's drive units were a research curiosity in 2006 and the dominant warehouse design pattern in the world by 2020.
Second, by ending Kiva's external sales after the acquisition, Amazon both denied competitors a turnkey solution and indirectly seeded an entire generation of independent warehouse-robotics startups. Almost every major non-Amazon warehouse robotics company traces some lineage to that decision.
Third, Amazon set a template that competitors have been forced to copy: own the automation technology, deploy it internally at scale, and treat the resulting cost and speed advantages as a strategic moat. Walmart's bet on Symbotic, Kroger's partnership with Ocado, and Target's investment in robotic micro-fulfillment are all responses to that template.
As of the company's own July 2025 milestone, Amazon Robotics operates the largest deployed mobile-robot fleet on the planet. Whether that fleet ultimately replaces, augments, or simply reshapes the work of the millions of humans who still pick and pack inside Amazon buildings remains the most consequential open question in the entire field of robotics.
