@DimitriProsser Is the world frame a pre-defined coordinate system by tf?

Hi,@janindu Thanks for your point. You are right. I‘m too careless.

Hi, I want to control the gazebo simulation by c++. My core code is below:

        ros::ServiceClient pauseGazebo = n_.serviceClient<std_srvs::Empty>("/gazebo/pause_physics");
        std_srvs::Empty pauseSrv;
        pauseGazebo.call(pauseSrv);
        std::cout<<"enter q to continue"<<std::endl;
        char key;
        std::cin>>key;
        if('q' == key)
        {
            pauseGazebo.shutdown();
            ros::ServiceClient unpauseGazebo = n_.serviceClient<std_srvs::Empty>("/gazebo/unpause_physics");
            std_srvs::Empty unpauseSrv;
            pauseGazebo.call(unpauseSrv);
            std::cout<<"q is pushed"<<std::endl;
        }

The puase work well, after I enter q, the "q is pushed" output, but the gazebo is still in the state of pasue. Can you provide some tip?

I'm using gazebo7 in ubuntu16.04.

I launch a bannana model in gazebo,everything is ok but the bannana will rotate slowly by itself.

urdf below:

Here is the workspace link,and there is a bannana.gif in the home directory to describe the question.

Can you give me some advice? Thanks a lot!

I enlarge the mass by 10 times, and enlarge the inertial by 100 times, the rotate disappear. It is just a solution. I do
