Hi,

Which rtabmap version you are using? /map -> /odom is published only if rtabmap is receiving data on its inputs. For convenience in recent versions, you would have this warning on the terminal:

Did not receive data since 5 seconds! Make sure the input topics are published ("$ rostopic hz my_topic") and the timestamps in their header are set. If topics are coming from different computers, make sure the clocks of the computers are synchronized ("ntpdate"). If topics are not published at the same rate, you could increase "queue_size" parameter.

telling what could be the cause.

cheers,
Mathieu
