transform failed error hector_mapping.launch #127
Description
Getting this error in hector_mapping.launch
[ERROR] [1682008316.190357265]: Transform failed during publishing of map_odom transform: Could not find a connection between 'odom' and 'base_footprint' because they are not part of the same tree.Tf has two or more unconnected trees.
Also what are the steps for mapping environment? I launchesd mir_driver and then I used hector_mapping.launch . Is this approach correct for mapping? There is no documentation.
