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.)

What Does A Robot See In The Mirror?
I couldn't resist comparing the #MoonDream 0.5b and 2b models looking at images of Dave or Wali.
The 2b model recognized Dave has a Minion character and is a robot.
The 2b model recognized that Wali is a robot but did not recognize the WALL-E character.
The 0.5b model simply hallucinates stuff, just like Ollama local models did for text queries.

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.

My #RaspberryPi5 #TurtleBot4lite robot WaLI (Wallfollower Looking for Intelligence) could really use an “off the shelf” mind!

First test of my new #ROS2 #Galactic #TurtleBot4lite power system.
This was the first discharge-to -20%-recharge-cycle in "as delivered" config.
Summary:
- max operating time, (to <20% charge), off the dock is about 1.75 hours
(No motion, just pubs Create3 topics, LiDAR scan, Oak-D-Lite color image, stereo 3D cloud, Localization and Mapper)
Recharge: ~2 hours
Battery "full": percentage = 1.0
If stays on dock after full:
- bot drains ~9 min to 95%,
- then recharges ~11 min to 100% -
Choosing a name for my new #TurtleBot4lite
Trying out:
WaLI - Wall follower Looking for IntelligenceWouldn't you think they would include a TurtleBot4 logo sticker (or two)?
Yo #ClearPathRobotics Its #ROS2 and a #TurtleBot4 - It needs a logo on it.

Am I the only person that did not know SSIDs are case sensitive?
Had one chance to setup my new #Turtlebot4lite Raspberry Pi4's WiFi without using wired Ethernet, and I blew it.
Luckily, had a laptop I could setup with a static IP, and luckily the drawer with the RPi4 can be opened enough to plug in an Ethernet cable.
Step 1: Connect TB4lite RPi4 to 5GHz WiFi done.
Now to Connect the TB4lite's Create3 base to my 2.4GHz WiFi.

>"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.

Any #ROS2 #TurtleBot4lite owners haunting this embodiment of the ether?
