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.

The robot revolution has long sounded like a far-off sci-fi notion, but it’s a reality at the e-commerce giant.

Amazon hits 1 million robots across 300 sites, boosting efficiency by 10%, as automation grows and human jobs in tech and logistics face mounting pressure.
