Dear friends

I tried launching gazebo with the following commands:

roscore
$ roslaunch youbot_description youbot_arm_description.launch
$ roslaunch youbot_description youbot_arm_publisher.launch

...... so first 2 are working fine and when I try to do 3rd one to launch gazebo it says gazebo successfully initialized and model was shown for 2 secs and after that it says process has died as described below..... so please if anyone can help it would be of great help ..... please try to help us.

Gazebo successfully initialized

Your log says that Gazebo couldn't find the file libgazebo_ros_controller_manager.so. It's in the package pr2_gazebo_plugins (in the stack pr2_simulator), so make sure that pr2_simulator is installed and run a rosmake pr2_gazebo_plugins.

Dear Martin

Thank you too for responding to our question and we tried what you suggested us and this is what we are facing now ..... Please check through this and help us for proceeding further ..... hope it will be understandable to you .....

Where exactly can I find this library seperately, I did try downloading the entire pr2_simulator and yet inside the pr2_gazebo_plugins I was not able to find this library..... so where can I get exactly and look also what we had got which is mentioned below ..... Please help us.....

regarding this, i have installed the pr2_gazebo_plugins, and when i try to run the command "$ make", i get this error:

Linking CXX shared library ../lib/libgazebo_ros_controller_manager.so /usr/bin/ld: cannot find -lpr2_controller_manager collect2: ld returned 1 exit status make[3]: * [../lib/libgazebo_ros_controller_manager.so] Error 1 make[3]: Leaving directory /home/youbot/ros_stacks/pr2_gazebo_plugins/build' make[2]: *** [CMakeFiles/gazebo_ros_controller_manager.dir/all] Error 2 make[2]: Leaving directory/home/youbot/ros_stacks/pr2_gazebo_plugins/build' make[1]: [all] Error 2 make[1]: Leaving directory `/home/youbot/ros_stacks/pr2_gazebo_plugins/build' make: ** [all] Error 2

and when i run the command "$rosmake", it get one failure.....

you also need all dependencies of pr2_simulator, in this case pr2_mechanism. It's best to install the Debian packages rather than compiling everything from source.

Martin Günther ( 2011-11-23 19:10:03 -0500 )edit

thank you, pr2_mechanism is also been installed and both make and rosmake works fine but we get the above shown error ..... and wt about debian packages ..... wr can we get those and how they r to be used .... please help us as this is the last stage for us .....

Dear Samsoem

Thank you very much for responding and i tried yours and this is what I had found and faced ..... please check this and respond to the result what we got ..... hope it will be understandable to you.

for this i tried running the third one second and second one third and the gazebo launches successfully without the robot object in it..... but before it says "Gazebo launches successfully" it gives few red lines, mentioned below:

This post is a wiki. Anyone with karma >75 is welcome to improve it.

Yes, I am on Oneiric. So I tried to compile pr2-simulator from sources. Unfortunately,

pr2_simulator/pr2_gazebo_plugins/src/gazebo_ros_controller_manager.h

has several includes that could not be found.

#include "gazebo.h"
#include "physics/World.hh"
#include "physics/Model.hh"
#include "physics/physics.h"
#include "common/Time.hh"

I was able to locate the first three and the last header, and changing to

#include "gazebo/gazebo.h"
#include "gazebo/World.hh"
#include "gazebo/Model.hh"
#include "gazebo/Time.hh"

solved the issue. But I don't have physics.h in my filesystem at all. Any ideas to where it belongs?

I get a similar error with libgazebo_ros_controller_manager.so, however that does not make my simulation to fail, i.e. the Gazebo window and a robot are displayed:

Error: [/tmp/buildd/ros-electric-simulator-gazebo-1.4.9/debian/ros-electric-simulator-gazebo/opt/ros/electric/stacks/simulator_gazebo/gazebo/build/gazebo/server/controllers/ControllerFactory.cc:101]

  Error Loading Controller of type [gazebo_ros_controller_manager], skipping

I tried to install pr2_simulator stack with apt-get, however it does not seem to exist (Ubuntu Oneiric):

$ sudo apt-get install ros-electric-pr2-simulator

Are you on oneiric? pr2-simulator has not been packaged for oneiric yet: https://code.ros.org/trac/wg-ros-pkg/ticket/5163

Is this caused by opening the same world model twice (i.e. an empty world) in multiple launch files?

Thanks for your reply. But its not happened by opening the same model twice. It is happening when we type the 3rd command which is a publisher one as I mentioned before.

what if you do the third one second? try renaming any same named nodes? I sometimes escaped this problem by very quickly launching two things after another.. before I found out what the real problem was, you can debug your lauch files by commenting out the code and then uncommenting it one by one
