I want to change a turtlebot3 navigation parameter called "inflation radius", I don't know how to actually go into the required yaml file to do so. I'm just confused. A book on programming the Turtlebot3 doesn't explain how to do so. The book just gives the following instructions: " ...The following is the parameter setting for the TurtleBot3 Burger........ ..... turtlebot3_navigation/param/costmap_common_params_burger.yaml". As seen, the instructions give the path,but I dont know where in my computer I can find this path. I have already looked at the ROS navigation stack wiki, it doesn't help at all. Please anyone with experience using Turtlebot3, please reply

@Mike Scheutzow I figured out my problem and it works now! I had duplicate files of turtlebot3_navigation in different places

When you set up this tutorial, you should have created a catkin_ws/src directory, then used git to clone turtlebot3_navigation inside of the src dir. That is the turtlebot3_navigation directory the book is referring to.

You don't say what OS you're using, but on Ubuntu it is common to put it at:

$HOME/catkin_ws/src/turtlebot3_navigation

gedit or nano may be used to edit this file and change your parameter. It's just a text file with a yaml extension.

@Mike Scheutzow I have the navigation stack, I tried changing the inflation radius in the common_costmap_params and it literally doesn't do anything. I have the package i the directory you suggested. I dont know what I am doing wrong. I am in gazebo simulation right now. Maybe this is why?Maybe it would work in real life?

Please create a new question for this. Make sure to tell us what is working, then ask your question. P.S. Unless you say otherwise, readers will assume you are running Ubuntu 18.

@Mike Schuetzow I'll make a new question. Everything works and my Ubuntu version is 18.04. I just don't know why when I change inflation radius in the costmap_common_params_burger.yaml nothing happens. I trying to change inflation radius of obstacles in a gazebo simulation so maybe that's why? Does the Turtlebot3_navigation package only work for the real life turtlebot3? Is there a different package I need to be looking into for simulations?
