Amazon's deliveries in Washington are to be delivered by its new autonomous vehicle, Scout.
The multinational e-commerce company are trialling the new delivery devices in Snohomish County, Washington.
They wrote in a blog post: "At Amazon, we continually invest in new technologies to benefit customers. We've been hard at work developing a new, fully-electric delivery system - Amazon Scout - designed to safely get packages to customers using autonomous delivery devices. These devices were created by Amazon, are the size of a small cooler, and roll along sidewalks at a walking pace. Starting today, these devices will begin delivering packages to customers in a neighbourhood in Snohomish County, Washington."
And Snohomish County are thrilled to be partnering with Amazon.
Snohomish County Executive, Dave Somers, said: "We are delighted to welcome Amazon Scout into our community. Similar to Amazon, we are always looking for new ways to better deliver service to our residents. From the latest Amazon innovation to cutting edge technology, Snohomish County is a great place for entrepreneurial creativity."
