Hello Laura,<br><br>I&#39;d like to know what teleop node are you using for controlling the p2dx? A custom or a standard one? I haven&#39;t  noticed if there&#39;s a standard teleop node for a p3 or p2. I&#39;m using ROSARIA and cturtle on ubuntu 10.04<br>

Hi Raph:<br>
<br>
I would like to know if you had any trouble using slam_gmapping to generate<br>
the map shown in the video you posted. I am using a pioneer p2dx with a Sick<br>
lms200 laser and used ROSARIA with the navigation stack as well. I have no<br>
problems teleoperating the robot and visualizing the laser scans in rviz.<br>
However, when I play the records of the bag files  generated and run<br>
slam_gmapping along with it I get the following error:<br>
<br>
&quot;TF_OLD_DATA ignoring data from the past for frame base_laser_link&quot;<br>
<br>
The map is sometimes generated though.<br>
<br>
I would want to know if you ever faced this problem.<br>
<br>
Thank you very much.<br>
<br>
Laura<br>
