Unit 3 - /map is not published

[julian.oe]

Hi there,
I created a Map in previous unit: the files ‘turtlebot_area.yaml’ and ‘.pgm’ are available in map_server package. I used the solution file for localization launch. When I launch the localization, the map does not get published.

Hi Julian,
several questions here. With the little information you provided, it si difficult to understand what maybe happening:

• Are you providing an initial localization to the localization system using rviz? If you haven´t done that, then the map transform to odom would not appear.
• Provide a screenshot of the terminal in which you launched the localization server
• Provide a screenshot of rviz with the map been shown on it when you have launched all
• provide your launch file that launches the map server and the amcl
