Transform from base_link to /map navigation stack error
Hi!
I'm installing the navigation stack in my own simulated robot, but when I try to launch I gave the next problem:
"Waiting on transform from base_link to /map to become available before running costmap, tf error: Frame id /base_link does not exist!"
Searching a little I found that normally the transform broadcaster of one robot publish 3 tf (odom->base_link_offset base_link_offset->base_link base_link_ofsset->baser_laser_link) but I'm not sure for what is exactly each one and what are the necessary for make the navigation stack run. By other hand, my robot only publish one transform trought the chassis->base_laser_link (as explained in this tutorial), so I think that there is the problem.
Can anyone help me?
