Starts map_server which publishes static map from a file on a ROS topic and amcl which uses odometry and data from the LiDAR sensor to estimate the localization of the robot on the map. Turns out the gazebo plugin was publishing to robot/laser/scan while my gmapping was subscribing to dd_robot/laser/scan. The gmapping package provides laser-based SLAM (Simultaneous Localization and Mapping), as a ROS node called slam_gmapping. launch in this case, but that launch file doesn't need/use that argument.

No launch files found. When i start the simulation the output of the terminal shows "Registering First Scan", after i set the "map" frame as fixed frame in rviz, when i move the bot using teleop_twist_keyboard node, the laser particles also moves along The following shows how this was done for the gmapping launch file. launch; In the Rviz visualizer, make sure the visualizers in the Navigation group are enabled. if it does not show up Changelog for package turtlebot_navigation 2.
