Automated Highway Systems (AHS) will likely have numerous items including sensors and other electronics that are not present in conventional highways, and these pose both unique problems and opportunities from a maintenance and construction viewpoint. This paper reports on a new and unique concept for maintaining AHS which could also benefit traditional highway operations. The paper discusses a system of multiple wheeled mobile robots that are coordinated to accomplish complex tasks, and are tethered to a support vehicle for accurate relative positioning, power, and other necessary supplies. Multiple coordinated WMRs are proposed since many AHS maintenance and construction operations will involve several concurrent subtasks.
