Hello I am trying to create map of my gazebo world with hector slam. First I am launching my world roslaunch evarobot_navigation MUAM_nav_mapping.launch world_path:=$(rospack find evarobot_gazebo)/worlds/MUAM_test1.sdf then I launch my slam file roslaunch evarobot_slam gazebo_slam.launch

    metobom@metobom-TULPAR-T5-V17-1:~$ roslaunch evarobot_slam gazebo_slam.launch
