Amazon is known for its efficiency, and robots are already playing a key role. 

There are several automation and robotics systems in the mix in Amazon's fulfillment network, some of which were on display at Amazon's re:MARS conference this year. 

Amazon first incorporated Atlas in its fulfillment centers in 2014. It looks like storage boxes that move, and it assists human workers in sorting and moving customer orders. 

The second generation is called Hercules, and it's faster and more efficient than Atlas. Together, there are about 200,000 Hercules and Atlas robots in use in Amazon fulfillment centers. 

What's next? In April 2019, Amazon acquired Canvas, a maker of warehouse robots. Soon, Canvas robotic carts - which uses computer vision technology to navigate orders around Amazon's fulfillment centers -- will be a part of the picture as well.
