I followed all your steps and they’re very straightforward. One issue though, I can’t seem to find the maps anywhere on my computer. You were able to access them but I can’t find them anywhere. Please help.
Hi, I started learning ROS2 with your Udemy course. Now I'm at the point of SLAM Mapping, to eventually build a robot swarm. I've now followed this tutorial but I'm not sure how to get a SLAM map for my real world LiDAR instead of simulated one. Can you help me out? Thanks in advance!
Foxy is now EOL (End of Life) since May. So I won't do any more Foxy tutorial, I will only focus on Humble and future LTS (Long Term Release) versions of ROS 2 :)

when I try to launch the Gazebo with turtlebot3 using mentioned the command this error comes to play "[ERROR] [spawn_entity.py-4]: process has died [pid 10879, exit code -2, cmd '/opt/ros/humble/lib/gazebo_ros/spawn_entity.py -entity waffle -file /opt/ros/humble/share/turtlebot3_gazebo/models/turtlebot3_waffle/model.sdf -x -2.0 -y -0.5 -z 0.01 --ros-args']." could you please give a solution for this one?
You're the best. Undoubtedly, the best resource on TH-cam. Thank you very much!
Great video! Thank you for your quality content!

when you save the map, you can provide a name/path. Otherwise, if you just do it from your home directory, the map should be there and easy to find.
For some reason gazebo doesn’t work for me
Please how to move robot backword in NAV2. Thank you
How can I scan and make a map of a real environment instead of the environment simulated on gazebo?
how to do this for custom gazebo world?

I would recommend the channel Articulated Robotics for that
any foxy tutorial ?

Not sure exactly, but something probably happened during the ROS2 installation. Could you try to remove ROS2, update the sources, and reinstall ROS2?
