Amazon’s Project Tetromino: pushing automation into delivery stations

# Tetromino is

# Why delivery stations matter

Delivery stations sit downstream in the logistics chain. They receive mixed packages and must sequence and load them efficiently into many different vehicles and routes. Automation has already transformed fulfillment centers where inventory is stored and picked, but the final-mile flow has remained labor-intensive because it requires rapid, on-the-fly organization and vehicle-specific sequencing.

# What the planning document says

The document reviewed by Business Insider outlined a staged investment and rollout: a pilot in 2028 with about $103 million of investment, five sites in 2029 and ten more in 2030, with each 2029 site estimated at roughly $85 million. The document claimed Tetromino could process packages at about 2.5 times the rate of Amazon's existing delivery-station design.

Amazon responded that the plan is an early-stage concept and that the specific financial figures and road map in the document are "inaccurate and don't reflect our current plans." The company reiterated it regularly explores and pilots technologies to improve safety and delivery experience.

# Key technologies and partners mentioned

# Amazon's broader push

Amazon has been expanding automation in warehouses and said it expects to more than double its fleet of robotic arms in 2026. The company has also tested software that recommends worker assignments as workloads change, and it announced automated machines in recent European delivery-station pilots.

Amazon's robotics chief previously framed robots as tools to improve safety and efficiency, but internal projections have suggested some robots could flatten hiring growth over time. In public comments for this story, Amazon emphasized initiatives are designed to complement the workforce and that employees remain central to operations.

# Industry context

# What this means practically

If Tetromino or similar systems work at scale, they would change how delivery stations are designed, increase capital spending on robotics and facility reconfiguration, and alter the mix of manual and automated tasks at the last mile. The planning document's cost and timeline figures provide a sense of scale, but Amazon's public response warns those specifics were not firm.
