Hi,

Did you do a map before trying to do navigation? In the video, I think the robot started in localization mode with rtabmap.db containing already the map. If you do so (reusing already created rtabmap.db in localization), the robot has to detect a loop closure with the map in rtabmap.db before it can show the whole map. It seems that the robot in your picture is not yet localized against the map in the database.

EDIT
Move around to try to localize. The best to localize is making the robot look same locations (same point of view) than in the map that have a lot of visual features (e.g., it cannot localize against a white wall).

cheers,
Mathieu
