Hi, i am working on irobot create and made a map with gmapping ,, Now i have the map bit i am trying to make the robot walk on the hole room by a plan ,, So i have tryied exploration stack to make the robot walk on the hole room

i loaded my map from /temp on RVIZ and run :

rosrun explore explore

the error is :

Done exploring with 0 goals left that could not be reached. There are 0 goals on our blacklist, and 0 of the frontier goals are too close to them to pursue. The rest had global planning fail to them.
Exploration finished. Hooray.

then i have tried the explore_stage Package to see it when i command :

roslaunch roslaunch explore_stage explore_slam.launch

the result is :

... logging to /home/salma/.ros/log/841f8926-96f5-11e2-84ae-00e04c4d0e3f/roslaunch-salma-G31M-S2L-2379.log
