Meet Amazon Scout, a delivery robot with a human chaperone (for now)

Amazon launches a delivery robot program in Washington.

Amazon launched a sidewalk robot delivery service on Wednesday, but it comes with a human chaperone.

"Amazon Scout," a blue-colored, six-wheeled, self-driving cart "the size of a small cooler," started delivering packages "at a walking pace" in Snohomish County, Washington, according to an Amazon blog post.

The pilot program is starting with a handful of autonomous robots in a Snohomish neighborhood, just north of Seattle. But that's not to say they'll be alone.

A fleet of similarly sized robots also took to the streets of Washington D.C. in 2017, dispatched by Starship Technologies, a startup created in 2014 by Skype co-founders Ahti Heinla and Janus Friis. This week, the company announced it would start using the autonomous robots to deliver Blaze Pizza, Starbucks, and Dunkin’ orders for a flat rate of $1.99 at George Mason University in Fairfax, Virginia.
