About upgrading my create3 to turtlebot4 lite and learning the turtlebot4 documentation

[alain-lnpcrd]

Hello everybody,
Hello @slowrunner
My turtlebot4 admiring his future playground

where it should never go.

Model defined with turtlebot4-setup

After generating the map with "ros2 launch tur looking to use lebot4_navigation slam.launch.py"
I'm trying to navigate my turtlebot4 in the map and I can't do it.
Nav2 / Launching navigation "ros2 launch turtlebot4_navigation nav_bringup.launch.py slam:=off localization:=true map:=/home/me/ma_maison.yaml"

and there I discovered that locating the robot solved the problem of the unknown "frame map" . (red stain in room on lower left upper wall)

My current problem is running the "Nav2 Goal" operation (in chapter 5. Navigation)
" initial pose first, then goal pose " like example to see in this paragraph.
Normally the path to execute should appear on the map but nothing happens despite multiple attempts.

Congratulations! That is great progress indeed - creating a map and localizing in the map. That is as far as I succeeded in slam-toolbox. My testing did seem to navigate if I set the goal close in front of the Create3, but not if there was an obstacle to avoid or if the goal was behind the robot's current heading.

Hello,In fact, to read only half of the information, I had simply forgotten an operation, launching " ros2 launch turtlebot4_navigation nav2.launch.py "
The movement takes place but often fails to reach its destination, and there the only solution found is to restart all the processes
