Updated his OS and #ROS2 Humble Hawksbill packages yesterday. #GoPiGo3 ROSbot Dave is still a unicorn sadly.

Having a #robot in your home can be humorous when the robot decides to talk unexpectedly.

Out of the blue my #GoPiGo3 robot Carl announced “??? STOP”.

Out of curiosity I reviewed his speech.log to find that he had blurted out “Executing STOP”. Then I reviewed his voice.log and found he thought he heard “I don’t list you stop”.

I was to blame for my ADHD robot’s outburst. I forgot to tell him “Hey Carl, Go To Sleep!” and he would have responded “Going to sleep; Listening only for ‘WAKEUP’”.

@pythonhub This is so cool, thanks!

I put it on my Pi4 2GB Ubuntu 22.04 Jammy #GoPiGo3 #robot and tried -
Input: “I love my robot, but my robot thinks"
Output: "I’m a robot. I’m not. I’m not a robot. I’m not a robot”

It used 1.4GB of virtual memory, 800MB of physical memory, all four cores at 100% for about 24 seconds.

I'm in a robot funk.

I want my robot to be "aware", "interactive", "self-contained", "always on", "learning", no subscriptions, programmable, (but not requiring me to program every capability), and I want a community of smart people with the same robot, that I can learn from.

I thought TurtleBot4 would fit the bill, but it had too many "issues", so went back.

I just watched Amazon's Astro Unboxing. Cool bot, but also not for me.

I'll just have to keep working with my #ROS2 #GoPiGo3

Loving #ROS2 #Humble on my #GoPiGo3 #RaspberryPi4 #robot

3 hours 47 minutes "life" with on-board #slam_toolbox synchronous #mapping running, and a little driving around the room:

@orionrobots more detail please. When my #ROS2 #GoPiGo3 #robot wanders the house, only the kitchen forms a good map. When I built a quick (and too flexible) playground, the #maps looked amazing. Can’t decide how much reality I want to deal with while learning.

Nick, I'm a robot hobbyist trying to enable inexpensive #ROS2 (Robot Operating System) education using the #RaspberryPi based #GoPiGo3 #robot

I am looking for folks to test my latest "ROS2/#Ubuntu 22 Server for GoPiGO3 Robots" image is you perhaps know any owners of this fun robot.

@RoboPack #Robots have rights, no?

Surely I am crazy to think anyone will ever use my Free Open Source Software "Headless Install #ROS2 Humble on #Ubuntu 22.04 Jammy Server for #GoPiGo3 Robots"
but version 4 uSDcard image is now available for #RaspberryPi 3B, 3B+, and #Pi4B. (Including work around solution for PiCamera image publishing to /Image topic)

Sometimes, when I get thinking this “ROSification” of my #RaspberryPi #ROS2 #GoPiGo3 robot is just too hard, I start dreaming of belonging to “Team Turtlebot” and wonder what that would cost me.

I put together this comparison:

Wishing for a new #ROS on #GoPiGo3 #robot person to appear on https://forum.dexterindustries.com

(A #RaspberryPi4 2GB and US$129 gives a great #ROS2 robot to start learning on.)

@brianb
Here is my #RaspberryPi #GoPiGo3 robot's crontab -e:
```
@reboot sleep 10 && /home/pi/Carl/nohup_loglife.sh
@reboot sleep 75 && /home/pi/Carl/nohup_juicer.sh
@reboot sleep 100 && /home/pi/Carl/nohup_wheellog.sh
@reboot sleep 120 && /home/pi/Carl/nohup_voicecmdr.sh
@reboot sleep 180 && /home/pi/Carl/nohup_healthCheck.sh
```

and this is one of the files it starts:

https://github.com/slowrunner/Carl/blob/master/nohup_voicecmdr.sh

**I think the key takeaway is to use full paths everywhere.**

On a "can't believe it" success high!

I couldn't get #ROS2 v4l2 camera node (#Ubuntu 22.04 Server on #RaspberryPi) to pass video, but did manage to build libcamera/libcamera-apps and and a node that passes 10 frames a minute.

I can visually see "what the robot is seeing" to compare with the current rviz2 map topic.

My #GoPiGo3 mounted RPi4 is running 30-40% cpu load, using 700MB memory, keeping a cool 55degC. Everything on the RPi except the visualization apps - rviz2 and rqt-image-viewer.

@talktech it would be for the #GoPiGo3 robot. Official support, maybe
