Hello friends,<br>
<br>
I have Cturtle installed using debs released on August03,10 for Lucid Lynx<br>
on Debian Squeeze.<br>
<br>
I am trying to run tutorial1.cpp of Karto Slam.<br>
Karto package has launch file karto_stage.launch.<br>
First it reports about abscence of 2dnav_stage package. Which is not present<br>
in <a href="https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle" target="_blank">https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle</a><br>
<br></blockquote><div><br>Hi Nitin, that package does seem to exist at <a href="https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/demos/2dnav_stage/">https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/demos/2dnav_stage/</a>. Are you sure your ROS_PACKAGE_PATH is set correctly?<br>

Changing path for world file to package 2dnav_slam_stage and launching it,<br>
Stage do not shows anything and rviz is empty.<br>
<br>
Following is the output:<br>

For running it, first world file needs upgradation so that pose is defined<br>
now as (x,y,z,yaw). I am not able to find reason for this. Any solutions?<br>
<br>
<br>
thank you<br>
