Graph-based exploration path planner
WebOct 26, 2024 · FAR Planner uses a dynamically updated visibility graph for fast replanning. The planner models the environment with polygons and builds a global visibility graph along with the navigation. The planner is capable of handling both known and unknown environments. In a known environment, paths are planned based on a prior map. WebAug 3, 2024 · The majority of planning algorithms used are based on the occupancy grid maps, but in complicated situations, the occupancy grid maps have a significant search …
