How to set Real Time Factor to 1.0 in Gazebo ROS Fuerte [closed]

edit

Hi guys,

I have a problem in simulating multi agent system. The real time factor in gazebo (using ROS fuerte) flows between 0.1 and 1.1. I tried to set the option updateRate to -1 in order to cast the real time factor to 1.0. Is there any kind of suggestion I can use?

My .world file looks like

<gazebo version="1.0"> <world name="default"> <scene> <ambient rgba="0.5 0.5 0.5 1"/> <background rgba="0.5 0.5 0.5 1"/> <shadows enabled="false"/> </scene>

<physics type="ode" update_rate="-1">
  <gravity xyz="0 0 -9.8"/>
  <ode>
    <solver type="quick" dt="0.001" iters="10" sor="1.3"/>
    <constraints cfm="0.0" erp="0.2" contact_max_correcting_vel="10000.0" contact_surface_layer="0.001"/>
  </ode>
</physics>

<!-- Ground Plane -->
<model name="plane1_model" static="true">
  <link name="body">
    <collision name="geom_1">
      <geometry>
        <plane normal="0 0 1"/>
      </geometry>
      <surface>
        <friction>
          <ode mu="50.0" mu2="50.0" fdir1="0 0 0" slip1="0" slip2="0"/>
        </friction>
        <bounce restitution_coefficient="0" threshold="1000000.0"/>
        <contact>
          <ode soft_cfm="0.0" soft_erp="0.2" kp="1000000000.0" kd="1" max_vel="100.0" min_depth="0.0001"/>
        </contact>
      </surface>
    </collision>

    <visual name="visual_1" cast_shadows="false">
      <geometry>
        <plane normal="0 0 1"/>
      </geometry>
      <material script="Gazebo/Grey"/>
    </visual>
  </link>
</model>

<light type="directional" name="my_light" cast_shadows="false">
  <origin pose="0 0 30 0 0 0"/>
  <diffuse rgba=".9 .9 .9 1"/>
  <specular rgba=".1 .1 .1 1"/>
  <attenuation range="20"/>
  <direction xyz="0 0 -1"/>
</light>
<plugin name="joint_trajectory_plugin" filename="libgazebo_ros_joint_trajectory.so"/>
</world> </gazebo>

Thank you for your time and responce. Best regards,
