[ros-users] Problem during ros run with stage

[Federico Rinaldi]

Yes, the window with the map and two robots (red and blue squares) pops up
but nothing moves; i think that the two robots have to move around in the
map (i used player and stage and one example was similar to this and some
robots were moving in the map)..
