 # Using for Navigation System 
+
 Introducing hokuyo_navigation2, an autonomous navigation package leveraging the high-precision self-localization of the RSF sensor.
 hokuyo_navigation2 is a suite of ROS 2-based navigation packages specifically designed for Hokuyo’s RSF sensor, supporting both indoor and outdoor environments. It integrates 3D-SLAM, self-localization, and the ROS 2 Navigation Stack (Nav2) to provide a high-precision, all-in-one autonomous mobility solution.
 Furthermore, its intuitive web-based GUI allows users to easily manage the entire workflow—from mapping to navigation—directly from a web browser.
 Note: Users are required to adjust and implement path planning and velocity command topics (cmd_vel) according to their specific drivetrain/mobile base.

 ## Overview
+
 This package consists of three main components: data acquisition, 3D-SLAM, and navigation. 
 By leveraging the high-precision self-localization output from the RSF sensor, it can generate 3D point cloud maps, 2D occupancy grid maps, and 2D waypoints. Utilizing this data, the system enables stable autonomous navigation in both indoor and outdoor environments.

 ## Getting Data
+
 Use the browser-based GUI tool to record a rosbag.

 ## 3D-SLAM
+
 A high-precision point cloud map is generated using graph-based SLAM, integrating LiDAR Inertial Odometry and RTK-GNSS.

 ## Navigation

 Autonomous navigation is performed using 2D waypoints, 3D point cloud maps, and 2D occupancy grid maps. Users can switch between two self-localization methods depending on their environment: mapless localization using RTK-GNSS and LIO, or map-based localization using 3D point cloud maps.
