Amazon on Wednesday introduced Blue Jay, a new robotic system designed to perform multiple warehouse tasks simultaneously.

The system features a series of robotic arms suspended from a conveyor-style track, each equipped with suction cups to handle items of various shapes and sizes.

According to Amazon, Blue Jay merges what were previously three separate robotic stations into one efficient unit capable of picking, sorting, and consolidating items in a single location.

The company said the technology aims to support employees with physically demanding tasks while improving efficiency and saving space.

Amazon is currently testing Blue Jay at one of its warehouses in South Carolina. The company says the system can pick, pack, stow, and consolidate about 75% of the items stored at its facilities so far.

Blue Jay adds to Amazon’s expanding fleet of robotic machines being rolled out across its vast network of warehouses.

The announcement comes amid increasing scrutiny of Amazon’s warehouse automation efforts, especially concerns about their impact on the company’s large frontline workforce.

A New York Times investigation published on Tuesday revealed that Amazon’s automation team projects it could avoid hiring more than 160,000 workers in the U.S. by 2027, generating savings of roughly 30 cents per item packed and delivered.
