Abstract
As a large indoor unstructured environment, the steel rolling shop has many unknown factors that greatly affect the full-coverage cleaning path planning of the cleaning robot. In this paper, a round-trip full-coverage path planning algorithm is improved by using the breadth-first search (BFS) algorithm combined with the improved A* algorithm to complete the full-coverage cleaning task of the steel rolling shop by the cleaning robot. First, the obstacles in the raster map are inflated using the expansion strategy to prevent the cleaning robot from colliding with the obstacles; second, the map is traversed with full coverage by the BFS algorithm; finally, the round-trip full-coverage algorithm is used for path planning based on the traversal information, and when it enters the dead zone location, the improved A* algorithm is used to find the unplanned nodes and plan an optimal path to escape from the dead zone. The simulation results show that the improved round-trip full-coverage path planning algorithm is more efficient than the traditional full-coverage path planning algorithm, and the proposed method can solve the complex problems in unstructured environment and complete the full-coverage cleaning task of the steel rolling shop cleaning robot.
