Yo Keegan - Question about mecanum wheels on your latest NE-Five:

Do mecanum wheels drive straight?
(Like dY < 1cm, dHeading < 2 degrees for dX of 1m)?

When you run him around the house and return is the encoder odometry totally bad?

My bot has a bit of "flopsy wheels" causing #ROS2 #localization / #nav2 with LIDAR and /odom to "lose it" on long excursions around my house.

Thinking about a new bot with #mecanum wheels instead of #DifferentialDrive with "flopsy" plastic motors

Interested In A SouthEast Florida ROS Users Group?

I'm in Palm Beach County FL, and tired of doing ROS alone. Let's make our ROS robots smart, safe, and reliable.

Amazon "recalled" lots of Astro Business Robots.

It would really be great if #Amazon would add a high-level #ROS2Jazzy node to the #Astro #robot

I'm sure those used Astro robots would be in high demand by the ROS community.

What's on my mind?

Disappointment and Disillusionment!

- Invested 7 yrs in #GoPiGo3 #robot
- Created #ROS2 nodes for #proprioception, #odometry, #LIDAR, #docking, #tts #mapping, #navigation, #simulation, #ObjectRecognition, and #LifeLogging

- My robot cannot safely and reliably navigate in my complex home environment.
- No slower turns, no inflation value can fix

I'm done, destroyed, no strength left for "one more try". GoPi5Go-Dave is on the shelf with other "reached its limit" robots.

The computer gods blessed me today!

Fifteen years ago, I bought my first Apple Mac computer and a #Canon MX860 "All-in-one" #printer at my first ever visit to an Apple store.

Several #mac_osx upgrade notices warned "some apps may not work" (Canon printer drivers long since stopped being updated)

Today, my Mac announced "Upgrade to Sequoia to work with [my new] iPhone. Afterwards: "Printer Driver not compatible, Contact Canon".

The printer still works perfect & with Sequoia! .. 15 years!

#Apple Answer To #RightToRepair

1) Appt. w/Apple: "replace battery in perfect 6 year old watch and perfectly good 6 year old iPhoneX"

2) Apple: "ooh, 'vintage' phone - we don't make the battery for this phone anymore. You should buy new phone. Months, if can even get a battery."

3) 3 days later: Watch arrives (completely new watch for $100 batt.)

4) Apple software will not set up new watch with "vintage" phone

5) $930 actual "phone battery replacement" (got $70 for old phone)

When Your Robot Is Lying To You

I discovered my 6 year old robot Carl was lying to me about his age.

The story: https://forum.dexterindustries.com/t/when-your-robot-lies-to-you/10011?u=cyclicalobsessive

(Robot Carl thinks he is special because he has a unique DOI - Digital Object Identifier.)

In ROS there is a URDF file (Universal Robot Description File) which allows the robot visualization application to show a symbolic robot and the robot and state publishers to update where the robot parts are located as the robot moves.

These files can be amazingly complex to get the values correct for every part of a robot to appear in the correct place, and for sensor data to be accurate.

Over the years I have created #GoPiGo3 #URDF files. Today the GoPi5Go-Dave file:

Tried Google Gemini to code a Python ROS 2 multi-threaded node that subscribes to 2 topics, calls 2 asynchronous services and has a main callback every 1 second that implements a state machine.

It got close but I would be learning to "program" Gemini, rather than learning to program ROS, and I don't want to debug code that was not tested to work.

Starting from ROS tutorials with code that has been tested has worked well for programming my robots so far.

18 months ago I tried to teach my Raspberry Pi4 robot to use TFlite to recognize American Sign Language. (0% accuracy)

Since then my robot upgraded to a Pi5 and an Oak-D-W spatial camera with a dedicated neural net processor, AND I learned that Google gave out $500,000 to encourage folks to teach their computers to recognize ASL.

Hopefully this will give my robot ASL as an input modality.

GoPi5Go-Dave now has a (virtual environment) Quantum Processor!

Installed Qiskit-Aer Quantum Simulator, and managed to get a few "example circuits" to run.

I have absolutely no idea what robot Dave can do with his Quantum Processor, nor how to design the logic circuits.

Supposedly a Quantum Processor could run circles around ROS 2 Nav2 (if I add a mobile refrigerator to my robot).

Ghosts In My Robot

I awoke this morning hearing a strange quiet whirring sound in the room where my #GoPiGo3 #robots Carl and Dave reside.

Tracked the sound down to GoPi5Go-Dave’s #YDLidarX4 scanning the room for ghosts he thought might attack?

No ghosts had infected his brain, but did find a ghost elsewhere.

Wiggling his cables stopped the spinning, but subsequent wiggles can start and stop the spinning.

I can’t deal with ghosts before breakfast, but Dave is playing more quietly now.
