#ROS_2

I heard the sound of my ROS 2 Jazzy robot WaLI (Wallfollower Looking for Intelligence) rotating in search of his dock to recharge.

"Head spinning" WaLI was trying to push my ROS 2 Kilted Kaiju robot Kilted Dave off the dock.

Lesson learned: they still need me.

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).

That's cool - I recently upgraded my #GoPiGo3 #ROS_2 #Robot to #RaspberryPi5

50.62 MIPS on Pi5 running 64-bit #PiOSBookworm with #Python 3.11.2:

After 2 years my #ROS_2 #GoPiGo3 #robot finally knows how to navigate - I'm amazed by #slam_toolbox and #nav2

Here's Humble Dave doing #mapping, #localization, and now #navigation

Now we're making progress. #GoPiGo3 #ROS_2 #robot Humble Dave managed 10 minutes of wandering the kitchen before needing assistance and did not suffer any instantaneous deaths. I'm very impressed with #slam_toolbox mapping and localization.

The computed map polygon is quite accurate to the physical room.

Test: Drove #ROS_2 HumbleDave #robot around the room once, then back onto his dock:

“Dead Reckoning” with #GoPiGo3 encoders only /odom claims x,y: 0.3, -1 heading: 39 deg
(300mm in front and 1m to left of dock, with heading error of approximately 39 degrees)

SLAM from LIDAR and GoPiGo3 encoders /pose claims x,y: 0.056,0.009 heading: 2deg
(56mm in front and 9mm to left of dock, with heading error approximately 2 degrees)

Analysis: Will need assistance similar to Carl's docking guide:

"There are only two hard problems in computer science: cache invalidation, naming things and off by one errors."

Here's a (partial?) list of unforced naming crusades undertaken by the keepers of ROS:
* It's not OSRF anymore, it's Open Robotics.
* It's not Gazebo, it's Ignition.
* Ha, it's not Ignition, just kidding.
* It's ROS 2, not ROS2.
