Energy efficient complete coverage of mapped areas by single and multiple robots

Abstract: Path planning for complete coverage whilst seeking to minimise energy consumption is not an idea which has been rigorously investigated in the past. This work details a new approach to this problem. The system described herein should prove useful for planetary exploration due to the limited supply of electrical power available to exploration rovers. Our system accepts as input terrain maps detailing the energy consumption required to move to each of eight adjacent points. Exploration is performed via a cost function which determines the robot's next move by selecting the lowest cost adjacent point as the next target. This system was successfully extended to groups of two, three and four robots by means of a shared exploration map. The energy consumed by our system was substantially less than that consumed by a boustrophedon (back and forth) coverage pattern.
