I am trying to do localization just using lidar . I uses the map generated by cartographer_ros and do localization using mrpt_localization(http://wiki.ros.org/mrpt_localization).
I tried using the command 'roslaunch mrpt_localization demo.launch', it create an existing map from the bag file, similar to 'rosbag play '.
THIS IS THE LAUNCH FILE:
However, after finish the mapping, the lidar location (tf) disappear. I wanted to locate the lidar location in real-time on a generated/existing map. Even after i launch the rplidar_s1.launch it did not work. SEND HELP!!
