"How will delivery by Amazon Scout work? Customers in Snohomish County order just as they normally would and their Amazon packages will be delivered either by one of our trusted partner carriers or by Amazon Scout. Customers can shop on the Amazon App or amazon.com and enjoy the same delivery options including fast, FREE Same-Day, One-Day and Two-Day shipping for Prime members.Meet Scout | Amazon blog
We’re starting with six Amazon Scout devices, delivering packages Monday through Friday, during daylight hours. The devices will autonomously follow their delivery route but will initially be accompanied by an Amazon employee. We developed Amazon Scout at our research and development lab in Seattle, ensuring the devices can safely and efficiently navigate around pets, pedestrians and anything else in their path."
