Robot Localization - Exercise 3.3

After making the changes as seen in the screen capture copied below, when I run “roslaunch husky_navigation amcl_demo.launch” in shell #1 and “rosrun rviz rviz” in shell #2 and open the graphical interface I do not see the Expected result for exercise 3.3". It is still showing the cafeteria map.

How can I sort out this problem?

Hello @bandu2356,

You can have a look at the solution for this Exercise at the end of the notebook (you will find a link that will take you to this Unit’s solutions). However, keep in mind that you will need to launch the new launch file from the package (in exercise 3.3 it’s asked to create this new package and launch file), so you will have to execute a command like this: roslaunch my_amcl_launcher change_map.launch.
