I can not get the “Expected results in exercise 3.3”, i.e. the new map as shown here. I have followed the steps as described in the Video. Completed the last step in Exercise 3.3 C ). That step is copied below.
I am not sure what command I need to execute in webshell #1.
I cannot see any code in your question. however, 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). Also, keep in mind that you will need to launch the new launch file from the new 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.
