A question about neuronbot2 SDF file in myself gezebo world #20
Description
English is not my native language,sorry for any spelling mistakes.
The following is my development environment：
．Ubuntu 18.04
．ROS Melodic Morenia
．Gazebo 9
．neuronbot2 melodic-devel branches
I try to put the neuronbot2 SDF file in Gazebo world I created, but when I run the world roslaunch file I get the error:
[ WARN] [1612512193.870927121, 0.102000000]: missing <topicName>, set to /namespace/default: ///imu_data

And I run rostopic list , I only get /tf /tf_static and gazebo topic
How can I use keyboard_control and gmapping?
