Simon,<div><br></div><div>From your screenshot, it looks like you need to actually attach that Laser Scan display to a topic. See where it says &quot;Fill in topic here&quot; with the red background? Click there and you ought to get a dropdown menu or a popup box. This will allow you to select whichever ROS topic you are publishing LaserScan messages on. If you don&#39;t see anything when you click on it, make sure that you there is actually a publisher of LaserScans running using (rostopic list -v could help with that).</div>

Sorry about that.  In our restructuring for releases, this package was accidentally left out.  We will work on getting it reviewed and released shortly. <br>
For now you can check it out into your ros tree using the following command. <br>
svn co <a href="https://code.ros.org/svn/wg-ros-pkg/trunk/sandbox/teleop_base" target="_blank">https://code.ros.org/svn/wg-ros-pkg/trunk/sandbox/teleop_base</a><br>

    Hi Guys,<br>
<br>
    I&#39;m trying to run the simulation with stage according to this page:<br>
    <a href="http://www.ros.org/wiki/simulator_stage/Tutorials/SimulatingOneRobot" target="_blank">http://www.ros.org/wiki/simulator_stage/Tutorials/SimulatingOneRobot</a><br>
<br>
    But I can&#39;t find the teleop_base. So how can I drive the robot in<br>
    stage by keyboard?<br>
<br>
    Cheers,<br>
    Simon<br>

Hi Tully,<br>
<br>
Thank you very much, this teleop_base package is working now. But when I run the rviz, I can&#39;t get any laser scan graph, I attach the screen-shot here. So what shall I do?<br>
<br>
Cheers,<br>
Simon<br>
