There is no Global Planner on Turtlebot3 Navigation Package

edit

i install ros melodic and the turtlebot3 package with the procedure on this link : http://emanual.robotis.com/docs/en/pl...

Then i want to edit the package for navigation, i want to change the method of global_planner from navfn to CarrotPlanner or GlobalPlanner. But when i edit the move_base.launch there is no base_global_planner, justlocal_global_planner. And the parameter on the param folder, there is no base_global_planner_params, just local_global_planner_params.

1. Why there is no base_global_planner on the launch and params file on the turtlebot3 ?
2. If i added it manually the params and edit the launch file on the turtlebot3 package, will it works?
3. Give me recommendation the full robot package for learning. (That there's no additional file that i must added it like base_global_planner on turtlebot3 package)

Thank you so much.
