Amazon's expanding fleet of robots includes: Hercules, a lifter capable of handling 1,250 pounds; Pegasus, which sorts packages on conveyor belts; and Proteus, the company's first fully autonomous robot able to operate directly alongside people.

Amazon's fleet of warehouse robots just hit a new milestone. The company announced Monday that it deployed its millionth bot to begin operations in a fulfillment center in Japan.

Now that Amazon has deployed over one million robots worldwide, it's keeping the momentum going with a new generative AI model to power them.
