I want to modify hector_slam. So, for a rearrangeable hector_slam I think i should create and build or install hector_slam in catkin_ws right?
I looked the tutorials and got confused so much. I created catkin_ws by following http://wiki.ros.org/catkin/Tutorials/create_a_workspace tutorial. Next tutorial is http://wiki.ros.org/catkin/Tutorials/CreatingPackage, description is how to create a NEW ros package using catkin. But I want to create/build or install an existing package(hector_slam) so should i follow this tutorial anyway?
