When I tried to spawn an SDF model into Gazebo through (already doing source devel/setup.bash)

roslaunch polaris_simple_control_plugin empty_world.launch

the SDF model initializes failed sometimes.

  • Some partitions lost image description
  • Or the vehicle runs away quickly in the Gazebo world

After quitting the Gazebo and doing roslaunch again,

we could get the normal model as shown in the following image

  • all parts appears correctly
  • the vehicle stops in the world until we send command to it.


  • Ubuntu 14.04
  • Gazebo 6
  • ROS Jade

The SDF model is at


I googled on above situations but didn't get anything that looked promising.

  • Is this situation a version conflict between ROS Jade and Gazebo 6?
  • Is this related to SDF model loading sequences?
  • How could we avoid this situation correctly?
