The robots are coming.
Amazon is set to carry out a trial of mobile delivery robots called "Amazon Scout."
Starting in the suburbs north of Seattle, the wheeled robots are about the size of a cooler and travel along sidewalks at walking speed.
Six robots will be used during this trial, which are much like those home floor vacs as they're designed to navigate around obstacles, including people and pets.
Amazon also has been working on and testing drone delivery.
