$ launch turtlebot3_bringup turtlebot3_model.launch Command 'launch' not found, did you mean: command 'launchy' from deb ruby-launchy (2.5.0-3) command '0launch' from deb 0install-core (2.16-2) command 'launchn' from deb csmith (2.3.0-6build1) Try: sudo apt install <deb name>
Or bring up the Turtle3

Or maybe just: To be tested (This must be pretty much the same as doing the bringup script
ros2 launch turtlebot3_bringup robot.launch.py
