EDIT: The topic of the answers is finally just to have a working ROS/Gazebo installation from the debs (not from the sources).

2 days ago, I was unable to spawn my robot in Gazebo due to technical error (a module not found, I did not copy the message). So I re-installed the gazeborospkgs and other packages (as described in the tutorial) from the sources.

The robot can now be spawned, but it is badly shaky. Again, I made very small modifications on the robot description and even after reverting them, I still have the issue.

Check the bug in video:

The robot description I'm using is more or less stable, and I would say that the bug does not come from it.

Any idea of where this comes from?


New installation tried this morning (10.11), still this kind of messages:

arnaud@hercules:~$ sudo apt-get install ros-hydro-gazebo-ros-pkgs ros-hydro-gazebo-ros-control

Not sure what to answer.


OK, new try (16.11) read this page first:

So I had to remove Gazebo and install it again to have the right version (1.9.1).

sudo apt-get install ros-hydro-gazebo-ros-pkgs ros-hydro-gazebo-ros-control

With the simple rrbot, I have the following error messages:

setting /run_id to e0dc536c-4fcb-11e3-831d-8ca98268036c
process[rosout-1]: started with pid [5315]
started core service [/rosout]
ERROR: cannot launch node of type [gazebo_ros/gzserver]: can't locate node [gzserver] in package [gazebo_ros]

ERROR: cannot launch node of type [gazebo_ros/spawn_model]: can't locate node [spawn_model] in package [gazebo_ros]

Did not have time to investigate further. I preferred to post it directly and have a look at it afterward.


My mistake, that came from an old install of gazebo_ros from the source. After cleaning everything, I have been able to start the rrbot, which is working like a charm. My robot, though, is still very very shaky.

Well, in fact Gazebo itself has been upgraded.

Did the upgrade fix your problem? Chances are some parameters associated with youbot need to be tuned.

I currently do not have access to my Linux box. I gonna test tomorrow.

In response to 'Edit 1': Since you are using ROS, I would recommend against installing gazebo-current. Instead, just install the gazebo package which is fully supported by ROS.

Thx. I have seen the notice page for ROS users. New error message in the edits. ;)

Last update, I had to clean the catkin_ws rep and the rrbot is now working properly. My robot is still bugged.

Here is an issue to track the youbot parameter tuning.

Thx Nate. I will probably analyse the robot description part by part to identify where that this behavior comes from.
