Years Asking - #ROS Issue Finally Solved

For years I have asked every human that would listen, why my ROS nodes complain about a shutdown exception. (And I mean **yeeeeeears**. )

Finally asking #GoogleGemini has shown the pattern that should have been in the ROS tutorials all along.

(I have a feeling the "if rclpy.ok():" is actually all that is needed. Have not tested sufficiently yet.)

Just had to try the #MoonDream Vision Language Assistant on my 4GB #RaspberryPi4 #GoPiGo3 #robot and my 8GB #RaspberryPi5 #TurtleBot4lite robot:

TL:DR; Pi5 with 2B model might be useful, but the 0.5B model will not be useful regardless of running on Pi4 or Pi5.

>"What's on your mind?"

My #TurtleBot4lite arrives today! I participated in the #iRobot #Create3 beta (via #simulation,
they didn't gift me with hardware), so I am familiar with the #robot's lower level #topics, #services, and #actions.

My #ROS2 #Galactic #Ignition #Gazebo crashes loading the default #TB4 world.

And TB4 comes up half embedded in an obstacle in the maze world, but managed #dock, #undock, #wallfollow and to drive the TB4lite around with a #teleop_twist_keyboard node.
