the first rossim, it will run for a few cycles but after closing and opening a few times it gives me this.
ctrl C to close the sim, then re run the command to open. ros2 launch turtlebot3_gazebo main_turtlebot3_lab.launch.xml

whats the process for starting and stopping the sim? at least resetting it. ctrl C? reboot?

crtl Z was crashing it, stuck to ctrl C to close and restart sim, looking good.

Ctrl + C is the right key combination.

Thanks for sharing the images. It looks like you are having a problem with the VM’s capacity. Are you running other programs on the side?

  • Which rosject is this?
  • Are you still having the problem?
