Amazon 'Scout' delivery robots will roam the streets of Southern California

A fleet of Amazon'Scout' delivery robots will roam the streets of Southern California as part of the firm's largest trial of automated'last mile' delivery. Last-mile delivery is the last stage of getting a package from a warehouse to your door, traditionally completed by a van or truck. Retailers and courier firms are racing to automate this process through the use of drones, either by land or by air. Amazon's latest roll-out follows a successful trial conducted in a small neighbourhood in Washington state earlier this year. Each Scout robot is a squat, bright blue device that gets around on six wheels.
