Hi Eitan,
After Robot traveled 50cm I ran rostopic echo move_base/status , it gave
following result meaning Goal achieved:
......
header: 
  seq: 317
  stamp: 
    secs: 1287133937
    nsecs: 804322043
  frame_id: ''

_______________________
Then I tried again by decreasing the resolution of the map from 0.05000 to
0.02500, but Robot even then traveled 50cm.
Then I gave checked with decreased controller_frequency from 20.000 to
10.0000 but I did not see any difference because I got the same warning on
the move base that Control loop has missed its desired rate of 20.000 Hz. I
do save the move_base file but decreased frequency does not show any impact.
The Robot moves 50cm and displays the same warning on move_base, and
rostopic echo gives move-base/status as above.

any idea plz?
One thing more, how can I assure that Robot is correctly localized seeing
the rviz?
thanks a lot.
regards
