check if topic /odom is getting any data or not, you can use laser odom by using package rf2o_laser_odometry

Actually, I encountered the same problem, but previous responses from others inspired me and I ultimately solved the problem. Below, I will summarize my experience This situation is a problem with the TF relationship 1、check your TF tree , Ensure the integrity of the structure from map to Odom and then to base_ink, and check it through "rqt_tf_tree" 2、Most overlooked situations，check the configuration files in the config folder of the slam toolbox，because the frame_id in the yaml file may different from your customized frame_id (for example odom、 base、 map），if it is different，modify the yaml file
