[Solved] ROS2 Tutorial -> SLAM - map does not exist

[Philpip]

I am trying to run the SLAM tutorial here:

SLAM | Husarion

But am having issues with the map frame and robot_description.

Initially I get the Frame [map] does not exist and there are no transforms from x to map.

Hello @Philpip,

Please read this topic.

[Solved] ROS 2 Tutorial -> 8. SLAM - No /scan_filtered on ROSbot

Hi, I’m Amin I am currently experimenting with ROSbot 2 PRO. Right now I’m following the SLAM tutorial on this specific page ROS2 SLAM . I have run every possible and docker images required for ROSbot 2 PRO. Problem is I reach a dead end because in the picture below it specifically said I need to have /scan_filtered topic which I don’t have, I do have /scan topic instead. What is the problem here?

Let me know if you managed to solve the problem.

Thanks Rafal,

I’m not clear on how to remap inside the container, especially as the lidar topic is already ‘scan’ there.

However, altering the slam.yaml and the Rviz files did appear to resolve the issue.
