Amazon has a vast battalion of robots to help ensure your new television arrives on time this holiday season.

The ecommerce giant revealed that it now has more than 15,000 robots in action at its fulfillment centers around the country, as well as Robo-Stow, a large robotic arm. The robots move shelves of products around the vast facilities to make employees and the company more efficient.

The robots are developed by Kiva Systems, a robotics firm that Amazon acquired for $775 million in 2012.
