Hey Dan,<br><br>A few questions for ya to help figure out what's going on:<br><br>1) Have you tried using the rxconsole tool to see if any useful information is being output from the system? If so, did you see anything that seemed to be complaining or giving warnings?<br>
<br>2) What launch files are you running on the erratic? Are they the ones in the 2dnav_erratic package? Or different ones that you created? We used to have an erratic in-house, but we don't anymore and its been awhile since the 2dnav_erratic package has been tested. If you're running with your own configuration, could you post the files so I can take a look at them?<br>
<br>3) Do you see any obstacles in nav_view? On second thought, rviz is a more powerful debugging tool for this kind of stuff. Have you tried using rviz to get useful debugging information (whether obstacles show up, a plan is created, etc)? You can find a tutorial on using rviz with the navigation stack here: <a href="http://www.ros.org/wiki/navigation/Tutorials/Using%20rviz%20with%20the%20Navigation%20Stack">http://www.ros.org/wiki/navigation/Tutorials/Using%20rviz%20with%20the%20Navigation%20Stack</a><br>
<br><br>Ok... take a shot at answering these and we'll see if that gives a bit more insight into what's going on.<br><br>Hope all is well,<br><br>Eitan<br><br><div class="gmail_quote">On Tue, Mar 30, 2010 at 3:57 PM, Dan Lazewatsky <span dir="ltr"><<a href="mailto:lazewatskyd@cse.wustl.edu">lazewatskyd@cse.wustl.edu</a>></span> wrote:<br>

Thanks for the response Eitan - <br>
I've created a map, and am trying to get an erratic to navigate in said
map using nav_view. I set up the robot according the the nav robot
setup tutorial, and when I run nav view I can see the map and set the
robot's initial pose, but trying to set the goal doesn't seem to do
anything. I get a printout from nav view saying "setting goal:
Position(...)" but that's all.<br><font color="#888888">

The wavefront package has fallen into a bit of disrepair as we favor
our move_base package for autonomous navigation. If you're looking to
run some autonomous navigation demos, check out the move_base_stage
package instead of the 2dnav_stage package. The 2dnav_stage package
will probably be removed in the near future to save people the
confusion.<br>
<br>
Hope this helps,<br>

Any ideas would be appreciated.<br>
