I would like to publish laser scans, that are performed by e.g the Hokuyo Model in Gazebo to ROS. I have tried this with Fuerte and Hydro without success.

I used this materials: Gazebo 1.9 ROS Hydro Ubuntu 12.04

I then started Gazebo with this command

roslaunch gazeboros emptyworld.launch

This then gives me these topics in ROS

rostopic list










In Gazebo I added the Hokuyo model which is already included. I can see the scanarea indicated in blue. I can'T see any new topic in ROS. I can see in the model.sdf that it uses the Plugin. Furthermore I noticed that a topic tag is missing inside the sensor tag. I added one. Still no publishing.Thas how the sensor section model.sdf of the Hokuyo looks like

    <plugin name="laser" filename="" />

How should I solve it? Thank You

Gazebo does not publish information to ROS by default. You need to install some plugins that will connect Gazebo to ROS. There are new of tutorials that describe how to do this at

I found an answer to a very similar question in this link: Beyond that, I'm afraid I can't offer any more advice as I am not that familiar with using laser sensors in Gazebo. I hope what I was able to share helped.
