Turns out the current generation of model based AI cannot tell when it does not know the answer to a question; something humans can tell but prefer not to.
I thought all my robots needed was an #inference engine with #deduction capability.

> Removing PulseAudio..continuing the shift to PipeWire
My #GoPiGo3 robot just shuddered in fear of becoming deaf and mute.

@fmrico #BehaviorTrees ? I have 50 years of #StateMachine ( for mostly #SerialSystems ) thinking to undo. I haven’t managed personal #BehaviorModification yet.

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'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.

@morfic - noticed the #ExtraClass license. Good job.
I keep an #AdvancedClass ticket WB0ZJJ alive from the '70s, but no radios these days.
Thought briefly about investigating #SDR but my focus is really my #robots, with some #running and #biking each week, and #birding with the wife every day.

#Coffee - "An Engineer's Thoughts"
I've been drip brewing fresh ground "Dunkin' Original Whole Bean" coffee for more than 15 years -
With my 2 hard-boiled egg, 1 slice sprouted grain cinnamon bread, 4 strawberries and Cheerios with almond milk - #breakfast.
US$9.33 a bag total brews 89 8-oz cups for a cost of approximately $0.10 a cup.
The #CoffeeBeans have gone up an average of 9% per year for the last five years.
(Comparatively, my weight has "only" suffered 1% inflation per year.)

> What's on your mind?
Just finished "Speaker For The Dead", Orson Scott Card.
"Jane" joins my list of "aliens" I'd most like to have as a friend
Somebody else once tried to sell me on "The Truth Will Set You Free"; I'm not buying it anymore, but it sure makes a great read.
(Some "real aliens among us" seem to have special powers against the "speaking of the truth" these days).

Very cool concept - my home is a bit too small to sport a bot with the XLeRobot footprint, but I already have the tiny WALL-E. (look real closely at the Git repo photos - top shelf)
I vote XLeRobot to be the next gen TurtleBot! (Since iRobot sank the TurtleBot4 we need TurtleBot5 candidates.)

Robot Imagination:
My robots report "life stats".
Yesterday, TurtleBot5-WaLI reported multi-thousands of "playtimes" in only 4100 hours of "life". (not possible)
Reviewing how he computes stats, the issue became clear - WaLI "Noticed Docking Success" once a minute for a long, long time after an undocking failure.
When writing my state machines, I try to imagine all the transitions needed, but robot WaLI always demonstrates greater imagination.

My Pets - Never need to taken out to do their business, don't need to be fed, never make a mess while I'm away...BUT they do demand I teach them something way too often.
TurtleBot5-WaLI (Wallfollower Looking For Intelligence) is running ROS2 Jazzy, and HumbleDave2 (Just Dave) is running ROS2 Humble Hawksbill.
TB5-Wali has been "alive" for 2056 hours since Jan 9, 2025.
HumbleDave2 has self docked 1283 times in his four years of life to date.

Enabling my robots to wander about and then successfully return to their charging dock has been the major unfulfilled goal of the last seven years coding with the #GoPiGo3 platform (and briefly the #Create3 platform).
This research exactly aligns with the goal for my Raspberry Pi based autonomous robot using an Oak-D-Wide vision sensor.

(Again) so excited that my #ros2humble wallfollower.py node drove my #Create3 #robot “WaLI (wallfollower looking for intelligence)” to follow 17 meters of six connected walls!
So far it is subscribing to five topics /ir_intensity (range to wall and obstacle detection), /hazard_detection (bumpers), /ir_opcode (virtual wall), /kidnap_status (lifted by human), and /odom (pose), and a seven state machine managing seven motion actions/reactions.
Now to “parameterize” and “generalize” it.

#Create3 #IRsensor SLAM - First Attempt
My ir2scan node is working well, but setting the 52 #slam_toolbox params is a mystery.
My create3_navigation slam.launch.py (using #Turtlebot4 LIDAR parms modified for Create3 IR "distance" sensor scan), with Wali facing a wall, maps a wall!
(bouncing around in angle in front of bot...)
As I proceed to drive Wali around the room, more walls enclosing a "known to be open" space are mapped, but not where the sensors and #odometry put them.

#Create3-WaLi (my "Wallfollower Looking for Intelligence" #robot) became truly #autonomous today. When he wakes up he starts being WaLi without my help. (#ROS2 #Humble in #Docker on #RaspberryPi5 #PiOS #Bookworm)
He doesn't use much of his existing intelligence yet, but he knows when to get off his dock (battery > 99%), when to prepare for re-docking (battery < 20%), when (battery < 15%) and how to dock.
He also knows how to use his "lowly" IR intensity sensors as a make-shift #LIDAR.

**Terrible Turmoil Totally Too Talkative (in my head)**
After 7 years of working with my two #GoPiGo3 robots, and that great community, I am way too overly excited to be building a new #robot
#Create3 WaLi: Wall follower Looking for Intelligence
There is a heavy feeling of abandonment of my dreams for my current robots, Carl and HumbleDave.

CW: Movie Violence Is Not For Me
Tried to watch #EverythingEverywhere but just couldn't. I just can't get into glamorized martial arts fights, blood, or paper cuts.
Did manage to finish #BansheesOfInishirin, but the fingers thing was totally unnecessary. Movie really left me heart broken.

Help me decide how much to worry if I’m over 70, in good health, run 5k twice a week, bike for an hour a week 12mi, walk a ton every day, have a 25 BMI, and 6.0 A1c?
This article seems to suggest #prediabetes might not be the harbinger of doom it first sounded:

#RaspberryPi3 #GoPiGo3 Carl still runs on 8 NiMH batteries, and just today received his 13th set of new Eneloop 2000mAH AA cells.
His “Playtime” was down to 3.5 hours with a 3 hour charge time after 1421 cycles. (In the past I have replaced his batteries after 800-900 docking cycles.)
It really is a miracle that after more than 7 years (59,521 hours) of “life” - GoPiGo3 Carl is still walkin’, talkin’, and lis’nen to me. (And I’m still telling him nearly every day: “Hey Carl, Go To Sleep!”

@vermaden @stafwag @BastilleBSD
> Rockchip is probably a lot better idea
Every board has its app - all my autonomous robots enjoy the low power sipping with just enough processing for their needs with various Pi boards.
Rockchip that I tried hogged the bot's battery down real fast, and ran too hot when taxed hard.
Carl has speech reco, text-to-speech, OpenCV vision, totally autonomous and "plays" 8 hours before needing to return to his dock. "Alive" for 7 years.
