KeyError: 'robot_description' rosbot_spawn process has died: cmd /opt/ros/melodic/lib/gazebo_ros/spawn_model -urdf -param robot_description -model rosbot_s -y 0 __name:=rosbot_spawn.
I have tried this using my computer with kinetic and rosbot 2.0 running an sd card flashed with kinetic same error. I have looked at the files and can’t find anything obviously wrong (I’m taking the courses on the Construct) and just happen to be on the section for urdf so I have some limited knowledge on what it should look like. I have made sure all the packages are installed. This happens on both the computer and on rosbot same exact error. All the previous gazebo launches have worked just fine.
