I have another problem that need your help,
I built a data.bag using rosbag
terminal 1: turn on rosaria
terminal 2: using keyboard to drive a robot
terminal 3: turn on hokuyo_scan
terminal 4: turn on tf between hokuyo_scan and base_link
terminal 5: rosparam use_sim_time true
termial 6: rosbag record -O data.bag /scan /tf
, but when i use rosrun gmapping slam.. and rosbag play and rosrun map_sever map_saver. I do not create a map.
Please, show me how can i fix it.
Thanks you advance in your help
Replace data.bag with just file name
it is not a main problem, i change data.bag to data , but i still meet the same situation above
Can you update your question by pasting the terminal outputs after running each commands, so that it will be easy to trace the problem.
