Hello. I have a problem in my sdf model.I am trying add this code to my robot model sdf:

<plugin name="gazebo_ros_control" filename="libgazebo_ros_control.so">
      <robotNamespace>/my_robot2</robotNamespace>

    </plugin>

I am running this on ubuntu 12.04 with ROS Hydro and Gazebo1.9. I do this on terminal: §optirun gazebo I use optirun because I have two graphics boards (Bumblebee). After having the gazebo running, and I try to insert my model in gazebo through the insert option of gazebo. But I receive this error when inserting the model and the gazebo close.

[FATAL] [1394020657.190138065]: You must call ros::init() before creating the first NodeHandle

    file = /tmp/buildd/ros-hydro-roscpp-1.9.54-0precise-20140130-2139/src/libros/node_handle.cpp
    line=151

Here is my model.sdf:

<?xml version="1.0"?>
<sdf version="1.4">
