Simulation problems

[OltanS]

Hi!

I was trying to run the simulation in gazebo as suggested, and realized the robot would not listen to navigation goals and moved randomly. I later figured out this is because the turtlebot3_drive node also publishes to the cmd_vel topic, and this node is started in sim_world.launch under human_aware_nav_launch (which starts turtlebot3_simulation.launch under turtlebot3_gazebo, which finally launches the node called turtlebot3_drive). Removing the:

<node name="$(arg name)_drive" pkg="turtlebot3_gazebo" type="turtlebot3_drive" required="true" output="screen"/>

line from turtlebot3_simulation.launch seems to have solved the issue, and the simulation now works as expected.

I'm very much a beginner with ROS so this might not have been the most elegant way to solve it, so I wanted to let you know that this problem exists!

Also the first page of the wiki says indigo twice instead of melodic.

Thank you for your time.
