i'm trying to do this job,here is the scene: I want to take my lidar move around a house ,and i hope nav2d could give me a path about how to move to the most proper frontiers,my slam algorithm is cartographer not karto. now i've already run the tutorial3.launch,but i still don't know how to achieve it with my own lidar and slam algorithm...for example i don't know how to modify tutorial3.launch to make it work.
