The maping system will use the cameras to create a map of the terrain in front of the vehicle.
the map will consist of small squares who's value indicates bumpiness. the fan map then is superimposed on the terrain map, and in the absense of goals, the fan map who's value is lowest is chosen. this would corespond to the road. if all fans have simmilar values, direction to the goal is used to choose a fan.
