 For Python, you should also check [Nav2](https://navigation.ros.org/) documentation to learn about the general concepts. However, Nav2 does not support Python directly, I have however implemented interfaces for a [Controller](https://navigation.ros.org/plugin_tutorials/docs/writing_new_nav2controller_plugin.html), and for trajectory generation and critic for the [dynamic window controller](https://github.com/ros-planning/navigation2/tree/main/nav2_dwb_controller) used by turtle bot, the code is available in [air_navigation](https://gitlab.liu.se/tdde05_ros2/air_navigation) 
 and some examples in [air_navigation_examples](https://gitlab.liu.se/tdde05_ros2/air_navigation_examples/-/blob/master/air_navigation_examples/__init__.py).
 
-For both C++ and Python, to use a custom controller and critic, you need to change the configuration of nav2, you can see example for using the air_navigation_examples (nav2_test_py_controller.yaml)[https://gitlab.liu.se/tdde05_ros2/air_bringup/-/blob/master/config/nav2_test_py_controller.yaml] and (nav2_test_py_dwb.yaml)[https://gitlab.liu.se/tdde05_ros2/air_bringup/-/blob/master/config/nav2_test_py_dwb.yaml].
