Oscar,<div><br></div><div>I just checked that navigation_stage/launch/move_base_multi_robot.launch works for me with the CTurtle 1.2.2 version of ROS navigation and 1.2.1 version of ROS simulator_stage.</div><div><br></div>
<div>Can you post the output of both "rosnode list" and "rostopic list" when the system is running? I'm curious to see if everything that's supposed to be up and running is actually up.</div><div>
<br></div><div>Also, what version of the navigation stack do you have installed? To check this:</div><div><br></div><div>roscd navigation</div><div>cat CMakeLists.txt</div><div><br></div><div>The version is the x.x.x number contained in the rosbuild_make_distribution macro.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">HI everybody,
<br>
<br>I'm trying to run the <tt>launch/move_base_multi_robot.launch</tt>
example launch file, it simulates two robots on different windows. But
when the windows of nav_view opens I don't see anything but the map
(image 1). Neither the inflated obstacles nor the particle cloud or the
robot footprint seem to appear. I also looked for information in what
was being published over those topics but there weren't any messages. I
also receive a warning message when I run the launch file but I don't
know if it has anything to do with it (Image 2):<br>
<br>[ WARN] [1285694547.646811796, 3.800000000]: The base_scan
observation buffer has not been updated for 2.10 seconds, and it should
be updated every 0.40 seconds.<br><br>This problem occurs also with the move_base_fake_localization_<div>10cm.launch
example, but in this case it opens a window from stage (Stage-3.2.2)
and from there I can see the footprint of the robot (image 3). Also when
I listen to the /odom topic (rostopic echo /odom) It prints the
following (image 4):<br>
<br>wist: <br> twist: <br> linear: <br> x: 0.0<br> y: 0.0<br> z: 0.0<br> angular: <br> x: 0.0<br> y: 0.0<br> z: 0.0<br>

<br>Could you please tell me the possible reason of why I cant see the
footprints of the robot or anything else besides the map on the nav_view
window?<br><br>The Version of Ubuntu I use is 10.4<br>The Version of ROS is CTurtle.<br>
The Version of Stage is 3.2.2.<br><br>Image 1: <a href="http://2.bp.blogspot.com/_ZcT6CZOJoq4/TKJgFCA9SAI/AAAAAAAAARU/3fuLlfe6LDk/s1600/Image+1.png" target="_blank">http://2.bp.blogspot.com/_ZcT6CZOJoq4/TKJgFCA9SAI/AAAAAAAAARU/3fuLlfe6LDk/s1600/Image+1.png</a><br>
