Hi,

the remaping seems okay, not sure why rtabmapviz is not using the new topic names. Well, you can set for rtabmapviz:

<param name="subscribe_depth" type="bool" value="false"/>
<param name="subscribe_scan" type="bool" value="false"/>

as they are optional. rtabmapviz will only subscribe to rtabmap/mapData.

For the problem "But it stops updating the map after the first frames even if i start to move the robot around... ": What are you showing in the terminal "average rate", is it the laser scan topic? If so it is indeed very slow, which would be difficult to synchronize with the camera or odometry topics. What is the framerate of odometry (/odometry/filtered)? If odometry is over 30 Hz, it will be indeed difficult to synchronize the topics. You may show what is the frame rate for all input topics to rtabmap.

Mathieu
