No map obtained gmapping
Hi, all! I am running gmapping slam by the next sequence of commands (all are in new terminals):
rosrun urg_node urg_node _frame_id:='laser_link'
rosrun navigation odometry_publisher
rosrun tf static transform_publisher 0 0 0.15 0 0 0 'base_link' 'laser_link' 100
rosrun gmapping slam_gmapping
but there is no map in rviz. When I add topic /map in rviz, it shows warning status and "No map obtained". Laser scan are shown well via /scan topic and odometry is also good, but there is no map. I have really no idea. I know this is a popular question and almost asked questions are refered to transformation issue. But my tf transformations are seem to be correct: map->odom->base_link->laser_link. I also run rviz on my remote machine and nodes on the local according to http://www.umiacs.umd.edu/~cteo/umd-e... . May be there is a special order of rosrun launching?
There was a too slow transform broadcasting rate between /odom and /base_link.
