The mobile unit with robotic arms would seem to have a lot of potential applications from delivery trucks to construction work. Moving sidewalks are a kind of automated conveying system. Some use of automated vehicles outdoors was described in Chapter 4. It is possible that all of North America's highways in the future will be designed for automated vehicle use only.
