"It can operate in a manner that augments simple, safe interaction between technology and people—opening up a broader range of possible uses to help our employees—such as the lifting and movement of GoCarts, the non-automated, wheeled transports used to move packages through our facilities," Amazon wrote at the time.

Proteus was initially deployed in the outbound GoCart handling areas in Amazon' fulfillment centers and sort centers.

At the same time, Amazon also debuted Cardinal, a robotic workcell that uses AI and computer vision to select packages out of a pile of packages, lift it, read the label, and place it in a GoCart, as well as Amazon Robotics Identification (AR ID), an AI-powered scanning capability with computer vision and machine learning technology to remove the process of manually packages, instead using a camera system that runs at 120 frames per second to scan the package automatically. 

The same year, Amazon revealed Sparrow, an intelligent robotic system that streamlines the fulfillment process by moving individual products before they get packaged, as well as Robin, a smaller robot arm, that can grab and rotates a parcel to scan the label and transfer it to employees if it sees any rips, tears, or illegible addresses.

In 2022, one billion packages, or one-eighth of all the orders the company delivered to customers worldwide, were sorted by Robin, and the company had deployed more than 750,000 mobile robots across its worldwide operations.
