Hi guys, I already posted this question to ROS answers and Gazebo forum without any result. You can find it at http://answers.ros.org/question/47507/gazebo-ros-fuerte-crash/ My question is about the new format of Gazebo, SDF. Is there any guide on how to include it in a launch file? This since I developed my code for ROS electric using XACRO format and everything works fine. Then, if the conversion into this format will solve my problem I will take my time and then convert all my files. If I run my code (adjusted for ROS fuerte/ Gazebo using plugins instead of controller and so on), the simulator crashes with an high frequency. I think that it is not my only problem and I'm asking if some of you has found a solution. Thanks in advance for any reply, Marco
