The gmapping package provides laser-based SLAM (Simultaneous Localization and Mapping), as a ROS node called slam_gmapping. Using slam_gmapping, you can create a 2-D occupancy grid map (like a building floorplan) from laser and pose data collected by a mobile robot.Adjust gmapping parameter to my robotBefore adjustment gmapping・gmapping(default parameter) : https://youtu.be/V3-TnQE2fugOther slam・cartographer(LIDAR only)... In the navigation package tutorial a static map is used, amcl is given the task of localization.
