On Ubuntu 14.04 Trusty I recently installed Ros Indigo using apt-get and the turtlebot packages from source following the instructions on turtlebot/indigo/instillation tutorial (but using rosdep install --from-paths src -i -y -r for the turtlebot modules). When I try to launch the turtlebot simulator using

roslaunch turtlebot_gazebo turtlebot_empty_world.launch

the turtlebot does not show in the gazebo window nor does the majority of the expected topics get posted (ie any of the /camera/* topics or /odom topic).

I'm using Gazebo 2.2.2, Ubuntu 14.04 and ROS Indigo I've sourced my the indigo setup.bash as well as the ones for the rocon, kobuki, and turtlebot modules from the instilation tutorial above. After starting the program the gazebo window will open and you can pan/zoom but none of the models will show on the screen, including any that I add after the program starts.

Below is the output of running roslaunch turtlebot_gazebo turtlebot_empty_world.launch

TurtleBot packages haven't been released or tested on indigo yet. You're getting a segfault which suggests a memory issue. If you can run it in gdb to get a backtrace we could try to help you remotely. Otherwise you'll probably need to wait for it to be tested and released. PS if you can also provide the steps to reproduce someone might have a moment to test your problem specificcally.

Thank you, I'm actually unsure how to run roslaunch turtlebot_gazebo turtlebot_empty_world.launch command in gdb.

same issue here. @charlie, it might also help to report this as an issue on the github of for example turtlebot_simulator (which contains turtlebot_gazebo).

I've figured out how to get this to work as a sort of semi-fix until the official debians are finalized and released. As fergs mentioned the problem is indeed with incompatabilities with ROS Indigo Gazebo and URDF. The temporary fix is to install Gazebo from source. This then lets gazebo use the urdf library that comes packaged with trusty.

Here are the steps I took from a fresh Ubuntu 14.04 install:

Install gazebo 2.2 from source. (I did the optional stage/player libraries as well) Install ros-indigo-desktop-full using apt-get Install ros turtlebot packages from source (only available option currently).

Use instructions found at:

There are still some issues with Gazebo and Indigo when using a URDF, see for the details.

Hi thanks for the answer. I just came across this as well after posting an issue on the turtlebot_gazebo github.

I gave this a try today. I had an old install of ROS Indigo, and after upgrading and removing the ros-indigo-urdfdom package, I'm able to run the turtlebot simulator using the precompiled version of gazebo.
