So there would be a variety of robots.  There would be lots of mini scouter robots.  These types of robots would be distributed throughout the grid.  Their job would be to detect when a break occurs in the wire and then to determine the exact location.  Then they would alert their commander and then either provide safety fixes, like cutting and capping wires or just setting up safety perimeters so no one gets hurt.  Then with the information gathered by the scouts (pictures/video, electrical data, course taken ie cutting or capping wires, approximate number customers affected) the commander can determine which robots to send out to fix the problem.  The decision to send out the type of robot will be done by a virtual agent.  However, a human will receive the info as well in order to determine whether emergency teams should be deployed to rescue any injured people.
