+            We need a stereo camera and velodyne point cloud looking like the real 
+            sensor (ring-like pattern), so we have to modifiy the default catvehicle 
+            urdf. First we have to install velodyne_simulator package to have the 
+            right gazebo plugin and copy this modified velodyne config: 
+               * sudo apt install ros-$ROS_DISTRO-velodyne-simulator
+               * cp ~/catkin_ws/src/rtabmap_ros/launch/config/catvehicle_velodyne_points.gazebo ~/catkin_ws/src/catvehicle/urdf/.
+            Secondly, we have to modify the triclops config to make it stereo:
+               * cp ~/catkin_ws/src/rtabmap_ros/launch/config/catvehicle_triclops.gazebo ~/catkin_ws/src/catvehicle/urdf/.
+            Set world->map frame instead of world->odom frame here:
