bunker no cmd_vel

[khuechuong]

I ran bunker gazebo command

roslaunch bunker_gazebo_sim bunker_gazebo_sim.launch 

but rostopic list doesn't show cmd_vel so I can't control its movements.

You can have a look of your terminal if there are some errors like missing controller,maybe you miss some dependencies because in my computer everything is running well

There are no errors in terminal. I have ros noetic.
