I want to combine the tutorial 2 and tutorial 3 such that the laser scan maps of tutorial 3 is displayed on top of the static map which we have from tutorial 2. I have been trying to write a launch file for this setup but it does not work. I see the static map initially but as soon as I move the robot I only see the laser scans only and the static map disappears. Also, when I did the sudo apt-get install ros-hydro-nav2d-* all the packages just have a cmake and .xml file. How is this tutorial even working without a source code ? "}}
