enter code here I tried to launch the parrot drone simulation download from The Construct but the gazebo didn't show after I type the following command:

$ roslaunch drone_construct main.launch

The following is the return message after entering the command above:

 ... logging to /home/chirantou/.ros/log/ec39ce5c-c963-11e9-9409-84a6c8434f72/roslaunch-chirantou-4610.log

Do anybody know why the Gazebo window didn't show?

updated:

I have tried other simulation model downloaded from The Construct like Turtlebot2. They work perfectly fine except the parrot ar drone model.

This is the main.launch file that i used for launching:

<launch> 
<include file="$(find sjtu_drone)/launch/simple.launch"> 
<arg name="world_name" value="$(find drone_construct)/worlds/ardrone_igniteworld.world"/>
</include>
</launch>

And this is the simple.launch file:

<launch> 
<arg name="paused" value="false"/> 
<arg name="use_sim_time" value="true"/>
<arg name="gui" default="true"/> 
<arg name="headless" value="false"/> 
<arg name="debug" value="false"/> 
<arg name="world_name" default="$(find sjtu_drone)/worlds/contest.world"/>

<node name="gazebo" pkg="sjtu_drone" type="start_gzserver" args="$(arg world_name)" respawn="false"/>

<node name="spawn_model" pkg="sjtu_drone" type="spawn_model" respawn="false"/>

</launch>

Can you post the launch file?

I usually launch gazebo <include file="$(find gazebo_ros)/launch/empty_world.launch"> and passing the world_name and gui argument. The latter one causes the client window to open.

This is the launch file "main":

</launch>

And this is the simple.launch file

</launch>

Just a suggestion , remove the following line in the main.launch file

modify the simple.launch file line

with

This would reduce some complexity for gazebo

I only see that the gz server is launched but not the client.

Should be a node of type type="gzclient". Have a look at the sjtu_drone if it offers also somethin like start_gzclient.

Have look at /opt/ros/melodic/share/gazebo_ros/launch/empty_world.launch as an example
