You're the best. Undoubtedly, the best resource on UA-cam. Thank you very much!

Great video! Thank you for your quality content!

how to do this for custom gazebo world?

[@abdullahusman6563]

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.

[@RoboticsBackEnd]

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

[@ilng2007]

How can I scan and make a map of a real environment instead of the environment simulated on gazebo?

Please how to move robot backword in NAV2. Thank you

[@sjoerdvgerwen]

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!

[@mr.p215]

I would recommend the channel Articulated Robotics for that

[@zoubaidahilali8339]

any foxy tutorial ?

[@RoboticsBackEnd]

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 :)

[@RoboticsBackEnd]

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

[@oviniakpura4663]

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?

[@grifithhhhhh]

hi same error. did you find any solution
