Key features

What is it?

Amazon Robotics Cardinal is a package handling robotic arm deployed at Amazon delivery stations and sort centres to lift packages from GoCart shelves and sort them by destination carrier route — a task that requires reading labels, determining routing, and handling packages of variable size and weight up to 50lbs.

Who is it for?

Cardinal is an internal Amazon system. It is documented here as the reference implementation for AI-guided robotic package sortation at the world's largest parcel operation, comparable to commercial systems offered by Honeywell Intelligrated, Dematic, and Vanderlande.

Key specs

The sortation challenge

Delivery station sortation requires reading each package's shipping label, determining its carrier route assignment, and placing it in the correct outbound area — at speed, across packages of variable dimensions and weights. The 50lb upper limit covers the vast majority of Amazon parcel volume.

How it compares

Commercial equivalents include Honeywell Intelligrated sortation systems, Dematic's AMR-based goods-to-person systems, and various unit sorter technologies. Cardinal's AI-first approach (vision-based label reading without physical barcode scanner requirements) represents a more flexible sortation architecture.

Limitations

FAQ

What does Amazon Cardinal do?

Cardinal lifts packages from GoCart shelves in Amazon delivery stations, reads their shipping labels using AI vision, determines their carrier route destination, and places them in the correct outbound sortation area — automating heavy repetitive lifting and sortation.

How heavy a package can Cardinal handle?

Cardinal handles packages up to 50 lbs (approximately 22.7 kg), covering the vast majority of standard Amazon parcel volume. Oversized or heavier packages are handled through separate processes.

Is Amazon Cardinal available to external customers?

No. Cardinal is an internal Amazon Robotics system deployed exclusively in Amazon's delivery stations and sort centres.

Why did Amazon develop Cardinal?

Cardinal targets one of the highest injury-risk tasks in Amazon facilities — heavy repetitive package lifting during sortation. Automating this task reduces musculoskeletal injury risk for associates while improving sortation speed and accuracy.
