Amazon is developing Project Tetromino, a proposed generation of highly automated delivery stations that could process packages at roughly 2.5 times the speed of current facilities, according to an internal planning document reviewed by Business Insider. The document outlines more than $530 million in capital investment by 2029, beginning with a $103 million pilot in 2028, followed by five sites costing about $85 million each in 2029 and 10 more locations planned for 2030. Amazon disputed the document’s financial projections and timeline, calling the initiative an early-stage concept. The project would automate labor-intensive final-mile tasks, including package sorting and delivery-van loading, potentially with artificial intelligence, robotics and technology from Boxbot, whose system uses storage trays and AI to sequence parcels and which says it can make vehicle loading up to 10 times faster. The effort follows Amazon’s deployment of more than one million warehouse robots in 2025 and broader systems including Cardinal, DeepFleet, Proteus, Blue Jay, Vulcan and Digit. Amazon also plans to more than double its robotic-arm fleet in 2026, has tested humanoid robots near Rivian electric delivery vans, and invested more than €700 million in European delivery-station technology from 2021 to 2025. The automation drive has intensified debate over employment, even as Amazon says technology is intended to improve safety and complement its workforce.
