[ros-users] Poineer's Path Navegation

Hi Eitan,
Thanks for the Reply.
I again checked it now. The Robot keeps moving backwards. Initially when I
set the pose it sees some obstacle before it. Also inflated obstacles
surrounded by Blue color. When I press 2D Nav Goal button of rviz and click
it in the map a little forward from the Robot, then Robot does not move
forward instead starts moving backwards. I observer the topics in rviz that
While moving backwards the obstacles it sees before it, slowly disappear and
new obstacles become inflated before it. 
But it always slowly move backwards and I had to switch it off. 

Any idea please?

I dont know where the topic /unknown_space is because I did not subscribed
it. I am following the tutorials
for SetUp http://www.ros.org/wiki/navigation/Tutorials/RobotSetup and for
Goal
http://www.ros.org/wiki/navigation/Tutorials/Using%20rviz%20with%20the%20Navigation%20Stack 

thanks in advance.
regards
