Path tracking control coverage of a mining robot based on exhaustive path planning with exact cell decomposition

Abstract

This paper addresses exhaustive coverage path planning of a mining robot based on cellular decomposition in minable area. For this work, the followings are done. First, the map of minable area is decomposed into cells by exact cell decomposition. Second, the coverage path is generated using back-and-forth motion. Third, direction of coverage path and generating graph path using proposed special spanning tree is considered to get minimum distance of moving path. The exhaustive coverage path is obtained by combining coverage path and moving path. Fourth, a controller is designed for a two-wheeled robot to track the exhaustive coverage path generated by path planning method. Finally, simulation and experimental results can prove efficiency of the proposed exhaustive coverage path planning method. ？ 2014 Institute of Control, Robotics and Systems (ICROS).
