Robotic workforce expansion

More than one million robots operate in Amazon warehouses globally. The company is constructing new facilities in Texas and Indiana to boost robotic production further. In July 2026, the chief financial officer confirmed plans to double the number of mechanical arms within the year.

Delivery scale for Prime subscribers

Amazon delivers tens of millions of packages daily to its 200 million Prime subscribers. Despite this scale, a study by George Mason University indicates that repetitive injuries are increasing in automated warehouse sites.

Origins of Amazon’s robotic fleet

Amazon built its robotic fleet after acquiring Kiva Systems in 2012. This pioneering company had developed mobile wheeled machines that could move entire shelves to workstations, reducing the need for employees to walk long distances between shelves.

Evolution of warehouse robots

Since the acquisition, Amazon Robotics has deployed multiple generations of machines. The Hercules and Titan models move through sorting center aisles, as wide as a billiard table or a grand piano, transporting shelves filled with plastic bins.

Internal innovations in automation

In addition to third-party handling arms, Amazon has developed its own machines. Robin, introduced in 2022, sorts envelopes and packages using eight suction cups and a computer vision system. Cardinal stacks packages onto rolling carts, handling up to 23 kg per unit. The latest model, Vulcan, tested in Spokane and Hamburg in 2025, uses vision and force sensors but has been deployed in only a few facilities so far.

Safety improvements in automated sites

An analysis of more than 150 Amazon sites in the United States reveals a contrasting picture. Automated centers report 40% fewer serious injuries compared to traditional warehouses.
