hello everyone , i have a question that i follow this tutorial link text,that i create a work dir "$ mkdir ~/gazebo_contact_tutorial; cd ~/gazebo_contact_tutorial" and next make an SDF world file with a box that has a contact sensor. "vim" ,the code is below ; then i run "$ gazebo " and i can see a box on the ground ,but when i type "$ gz topic -l" i can't see /gazebo/default/box/link/my_contact

if anyone know why , help me please ~


<sdf version="1.4"> <world name="default"> <include> <uri>model://ground_plane</uri> </include>


<model name="box">
  <link name="link">
    <pose>0 0 0.5 0 0 0</pose>

    <collision name="box_collision">
          <size>1 1 1</size>

    <visual name="visual">
          <size>1 1 1</size>

This is a gazebo question; you'll probably get a better answer on the gazebo answers site:
