2. If map of the arena is avaialble, skip to next step, otherwise follow the steps to create a map

   a. start mapping using slam_toolbox

   ros2 launch eddie_navigation online_async_slam.launch.py

   b. Use teleop to move the robot around

   c. After mapping, save the map using following command from eddie_navigation/maps/ path

   ros2 run nav2_map_server map_saver_cli -f map_name --occ 0.65 --free 0.15 --ros-args -p save_map_timeout:=20.0

3. Run the navigation launch file

   ros2 launch eddie_navigation eddie_nav_bringup.launch.py map_name:=<map_name>.yaml

   • The maps are available in maps directory
