Description

For achieving SLAM we rely on the great slam_toolbox package.

Usage

After the robot bring up, simply execute the provided launch file.

ros2 launch andino_slam slam_toolbox_online_async.launch.py

Several configuration can be forwarded to the slam_toolbox_node. By default, the configuration parameters are obtained from config/slam_toolbox_only_async.yaml. In case a custom file is wanted to be passed, simply use the launch file argument for indicating the path to a new file.

ros2 launch andino_slam slam_toolbox_online_async.launch.py slams_param_file:=<my_path>

For saving the map you can use map_saver_cli node provided by Nav2.

ros2 run nav2_map_server map_saver_cli -f <my-map-name>

You can modify the threshold for free space (0.25) and occupied space (0.65) by using --free and --occ arguments.

ros2 run nav2_map_server map_saver_cli --free 0.15 -f <my-map-name>
