This question has been asked before in this forum at least once (http://answers.ros.org/question/199401/problem-with-indigo-and-gazebo-22/). Nevertheless, i haven't found the cause behind the occurrence of the following Gazebo GUI errors,

 - Error [Param.cc:181] Unable to set value [1,0471975511965976] for key[horizontal_fov]
 - Error [Param.cc:181] Unable to set value [0,100000001] for key[near]

Things performed :: I successfully installed ROS Indigo on Ubuntu (Description: 14.04.02 LTS, Codename: Trusty) 64-bit virtual machine by following the instructions from the website http://wiki.ros.org/indigo/Installation/Ubuntu.

Later, i tried to launch the gazebo simulator to visualize universal robot by going through the tutorial mentioned in the website http://wiki.ros.org/universal_robot/Tutorials/Getting%20Started%20with%20a%20Universal%20Robot%20and%20ROS-Industrial.

The following is the result of launching the gazebo simulator ::

Due to the above resulted Gazebo GUI errors, the universal robot was not able to move in the gazebo simulator when i run the pre-defined python script file "test_move.py" (which comes with the ros-industrial package of universal robot) from another terminal window. This was the situation which i faced two weeks ago.

Despite the same above mentioned Gazebo GUI errors, now I can clearly see the universal robot moving in the gazebo simulator when i run the same python script file "test_move.py" from another terminal window. This was the situation which i am facing right now.

I started to do workaround by following the possibility mentioned in the website http://answers.ros.org/question/199401/problem-with-indigo-and-gazebo-22/

Possibility::

update Gazebo 2.2, but you must add packages.osrfoundation.org at Ubuntu repositories.

sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu trusty main" > /etc/apt/sources.list.d/gazebo-latest.list'
wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -

Before even trying the above mentioned possibility, i checked whether i have the "setup.sh" file of Gazebo simulator in the following directory, i.e.,

• /usr/local/share/gazebo-2.2/setup.sh

Unfortunately, i don't have the required gazebo-2.2 folder in the directory /usr/local/share.

Query ::

Is the absence of gazebo-2.2 folder and its setup.sh file in the directory "/usr/local/share" has something to do with the Gazebo GUI errors?

Can anyone suggest me where to look for so that the Gazebo GUI errors can be solved successfully?

Thanking You,

BR,
