You can use the same launch file as for turtlebot_empty_world.launch. You should copy the launch file to a package you've created (any package will do). Then change the line

<arg name="world_name" value="$(find turtlebot_gazebo)/worlds/"/>


<arg name="world_name" value="worlds/"/>

I just tested it and it works fine on my computer. Good luck!

Unfortunately it did not work for me.When i run roslaunch command,only an empty world and a turtlebot on the gazebo screen.Should i change empty_world.launch file?Thanks. <include file="$(find gazebo_ros)/launch/empty_world.launch"> <arg name="use_sim_time" value="true"/> <arg name="debug" value="false"/> <arg name="world_name" value="worlds/"/> </include>

So you've copied "turtlebot_empty_world.launch" file into a new package, then renamed the launch file, then launched it? Are you sure you're not launching the old one? Can you get the mud world to load in gazebo using the launch file here:

I have just done all you said, respectively.But when i started my new ros package with my renamed launch file,there was only an empty world and a turtlebot on gazebo screen.Also i tried all of roslaunch command with 4 different world which specified on your link,but only did not work.The other ones have run successfully. Should i do any other configuration for willowgarage to run on ros hydro? Thanks.

Can you launch empty_world then go to "insert" in Gazebo and try inserting Willow Garage manually?

Just a hint: willowgarage world is massive, and takes much longer to load in my PC. Maybe you run out of RAM?

My programs run with 6 gb ram.Maybe i must try another map.Could you advise another map in gazebo,actually i need a world just like a room.

You can easily do a simple maze-like map with gazebo's building editor (Ctrl + B). We did this for showing Turtlebot2 navigation in gazebo:
