Meet Sparrow, Cardinal and Proteus. They’re the robots that, step by step, are replacing human workers in the company’s warehouses.

In one post, Amazon highlighted Blue Jay, a robot it calls “an extra set of hands that helps employees with tasks that involve reaching and lifting,” and its agentic AI system Project Eluna, which “acts like an extra teammate, helping reduce that cognitive load” while optimizing sorting to reduce bottlenecks.

Operating like a juggler, Blue Jay can handle tens of thousands of items moving at high speeds with the goal to serve as the core technology to further facilitate same day delivery. The robotics system is currently being tested at one of Amazon’s ( NASDAQ: AMZN) fulfillment centers in South Carolina.
