As the title says, I would like to use a single map database to localize multiple robots via ROS. Here is my setup:

- Four identical mobile robots, each with a stereo camera mounted in the same place
- An existing map built with rtabmap_ros using one of the robots
- A remote machine running rosmaster

Assuming all networking between machines is handled, is there a way that I can serve the map database on the remote machine and have each robot use it to localize itself within the map? I am trying not to load the database on each robot.

Thank you!
