Hi all,
I have a bag with scanner data. I am not trying to build a map.
THe scanner is in /scan.
So I ran
rosparam set use_sim_time true
roscore rosrun gmapping slam_gmapping scan
rosrun tf static_transform_publisher 0 0 0 0 0 0 base_link laser 100 Nothing seems to be published in /map.
In rviz, I see for map... transform:No transform from [] to [laser]
What am I missing?
From the doc, I can see base_link → odom is needed.. How?
Why is that needed? Is not the purpose of slam to determine just that? (the base_link relative to odom)?
