getting ready for the D-Robotics #livestream next week! I first met the team at #MakerFaire #Shenzhen, and have had a blast collaborating with them and exploring their products since! The #DRobotics #RDK X5 has 10 #TOPS of compute for less than an 8GB #RaspberryPi 5 — no HAT required! Stay tuned for details on our upcoming livestream...

J’ai publié un article sur la #RDK X5 de D‑Robotics @DRoboticsDev

“How are we feeling about robots bumping into walls?”
Listening in on the #ROS2 intro tutorial at #ROSCon2024 as I do final prep to talk to the class about contributing to #OpenSource soon. 
I am currently working through dependency hell with #ros. It is not fun.
"What's that? You want to run a ros2-ros1 bridge in a container? AND run a #ros2 node on the host? So you can test that some newer ros2 code can publish to a topic and see if the old ros1 device picks up the messages like advertised? HAHAHAHAHAHAHAHAHA FUCK YOU"
Fine. You want a separate IP address per node. *That* makes sense at least.
/me proceeds to figure out how to get macvlan shit working for podman so that a rootful container can get an ip address from dhcp and have its own IP. This also involves, on #Debian at least, introducing some systemd unit files that the official package doesn't include for whatever reason.
"HAHAHAHAHAHA NICE TRY. WE'RE STILL GONNA RESOLVE ROS_MASTER_URI WITH THE HOSTNAME EVEN IF YOU PUT THE IP IN ROS_MASTER_URI ENV VAR"
But the container is ephemeral! I don't know the IP-Hostname pairs ahead of time!
/me proceeds to study ROS_IP
JFC. I've resorted to this god-awful hack in my podman run call for executing the bridge:
bash -c 'ROS_IP=$(ifconfig | grep eth0 -A 1 | tail -n 1 | awk '"'"'{print $2}'"'"') ros2 run ros1_bridge dynamic_bridge --bridge-all-topics'
IT'S QUOTE ESCAPING ALL THE WAY DOWN, FOLKS!
I know the docs say "fuck you, make the names resolve," but I'd rather not fuck around with modifying /etc/hosts on a bunch of nodes just to make ros happy.
Oh. And once you use ROS_IP, you are married to it. EVERY node's gotta use it. All or nothing.
FFFFFFFUUUUUUUUUUUU
Yeah. I'm glad I switched careers to nursing. (all of this has been an exercise in helping someone else navigate the ros landscape, which I was blissfully unaware of until now. But at least they're gonna get my help :P )
Anyone here got spare #ros2 #ironIrwini stickers they'd be willing to mail to France? I ordered the only ones they had in the official Spring store front but they seem a little more... imposing than I anticipated. I'd wildly guess they're about 2.54 times too imposing. 
Totally unrelatedly, if anyone wants to tag a robot with a slightly pixely sticker big enough to be seen from space, hit me up. 
O3DE has become a rising star in the world of #robotic #simulations. Robotec has joined as a new member, contributing new #ROS2 and #Lidar gems, and Adam Dabrowski shares how #O3DE is developing the next generation of robots.

Looking for someone with Docker experience to review this ROS driver for a PS4 controller. https://github.com/adityakamath/ds4_driver_ros/tree/humble-devel
I had to split up message generation from the driver nodes to support ROS 2 Humble, not sure if the Docker scripts still work...

Happy #MagPiMonday / #MagPiTuesday
I created a new robot called Cubie-1 over Christmas. It's powered by the

4 8Gb and the

Explorer hat.
It has an

16mp Autofocus camera and a LIDAR on top so it can sense its environment.

Any #ROS2 #TurtleBot4lite owners haunting this embodiment of the ether?
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.
with an Elec Eng and Robotics background?
