I'm info dumping some links about open-source robotics. The rabbit hole runs deep and this barely scratches the surface.

Disclaimer: I haven't tried any of these yet. Based on a cursory search and following links from the great Open-source robotics Wikipedia page.

Robotics simulation on Godot

• https://github.com/flynneva/godot_ros - Proof-of-concept integrating ROS2 (Robot Operating System) with Godot, for a 3D robot simulation environment. (Updated 8 months ago)

• https://github.com/nordstream3/Godot-4-ROS2-integration - A fork(?) of the above. The readme is clearer with visual examples of what it's meant for. (Updated 12 months ago)

• https://github.com/plaans/gobot-sim - A top-down 2D factory simulation of packages being processed by machines. (Updated 3 months ago)

• https://lab.nexedi.com/nexedi/godot-modbus-demo - Exposing a modbus interface to control simulated industrial components. (Updated 5 years ago.) Comes with a blog post which might be more recent (a year ago?).

• https://arxiv.org/abs/2412.18408 - "Exploring Flexible Scenario Generation in Godot Simulator" about generating simulated physical scenes for testing computer-controlled cars. Write-up only with no code. (Submitted 9 months ago)

Robotic car simulation on Unreal Engine and Unity

• https://github.com/carla-simulator/carla - "CARLA is an open-source simulator for autonomous driving research." They mostly target Unreal Engine. Regularly updated and popular with 13k stars on GitHub.

• https://github.com/microsoft/AirSim - Microsoft and IAMAI collaborated (plus DARPA funding?) to create an open source simulation platform for both flying drones and autonomous cars. Targets Unreal Engine and experimentally Unity also. Soon being sunset and replaced with a new project confusingly named "Project AirSim."

• https://github.com/iamaisim/ProjectAirSim - The successor to AirSim. The GitHub shows it's only at version 0.1.1 though.

Robot Operating System (ROS2)

• https://github.com/ros2/ros2

• https://docs.ros.org/en/kilted/Tutorials.html - Tutorials beginning with TurtleSim, a top-down 2D turtle scene where you control turtles. Looks like ROS2 uses familiar network messaging patterns like Publish-Subscribe.

• https://vimeo.com/osrfoundation/videos/sort:date - Presentation videos. Looks like the Open Robotics foundation just completed a developers' conference in Japan two days ago. The presentations from ROSCon JP are Japanese-language-only. Next one is coming very soon this October in Singapore.

How to get started?

That's a lot of links. I'd first figure out what I want to do. Humanoid robots seem popular lately—like the Berkeley 3d printed robot—so it'd be interesting to start there, although it doesn't map cleanly onto the projects I linked. So maybe if I imagined a robot with a human torso and arms, but with wheels and car-like locomotion. Then I could use a combination of the car simulators and probably ROS2 to deal with the upper body components? Or maybe there is another solution for the torso and arms that is a more direct fit than ROS2? Maybe iRobot/Roomba has a better solution for the car-like locomotion at this small scale?

Anyone used these before and have a story to share? Anyone curious to try one out and report back? I plan to, but no idea on my schedule.

Welcome to the 2025 NFL Season Weekly Discussion Thread! 🏈

Share your thoughts on Week 4 — wins, losses, fantasy fumbles, predictions, or anything else football-related. Sorry for the delay posting today, I was away from a computer all day and just now have time to post this :)

Have you watched any movies recently you want to discuss? Any films you want to recommend or are hyped about? Feel free to discuss anything here.

Please just try to provide fair warning of spoilers if you can.

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

Wondering if we have tilde fellows playing it. I’ve become addicted since last year and it’s fully taken over my regular board game nights… I’ve been storytelling and doing custom scripts and characters.

As someone who DM's a lot of short, casual sessions with rotating members, I burn through a lot of maps. I'd love to hear some of your recommendations for how you guys either find or create maps that suit your situations.

For me: r/battlemaps has some really high quality stuff and gets me 90% of the time. I usually type in a key word or two (e.g. bridge; throne room) and usually I'll find something that gets close to the mark.

I know that some have been using generative AI to delve into this space as well, so if anyone has any experience there, I'd love to hear it!

Flames flicker as the once mighty Orient Express lies on its side in pieces, bodies in cartoonishly thuggish costumes scattered all around. After a long three days full of murder, deception, concerts and romance, its final journey has come to a fiery end.

From the inferno, a single figure emerges in a scorched trench coat, dark hair ruffled by the breeze. He brushes off the coat with one hand and smoothly extends the other, and a solid gold bird swoops down from the sky to perch on it. Red flames flicker along its wings and back, but his sleeve remains perfectly untouched.

He walks away from the burning wreckage, arm still outstretched with gleaming golden bird atop it. Sunglasses descend from the sky and land squarely on his nose. A second smaller pair studded with jewels descends and lands on the bird's beak, managing to somehow look cool instead of ridiculous.

“Time to kick some Nazi ass,” the man declares, and the bird caws.

The train explodes behind them and the air reverberates with a “Yeeeaaaahhhh!”

Note: the above scene may not be 100% accurate or canon.

So concludes the first leg of the Colossal Game Adventure!

We hope you enjoyed your time aboard The Last Express. For anyone who missed the initial boarding period... Well uh, luckily this game involves rewinding time, so you can just rewind here to the Insert Cartridge topic when the train was intact. Feel free to post there if you're just starting the game, or you can post here after finishing even if you're only finding these topics months later.

That said, presumably most of you boarded earlier and had a chance to play the game. As such, this post will not require spoilers to be hidden in dropdown blocks. So if you don't want to be spoiled, please adjust your clock and rewind to the previous post.

Use this post to share final thoughts and impressions, post fun little secrets or easter eggs you found, ask questions if you had to abort your playthrough for whatever reason, link video clips, discuss if you completed any of the meta challenges, etc. Or you can share and express admiration for the very nice official Colossal Game Adventure splash screen made by @Boojum which I meant to link last time on "Press Start", but accidentally pasted the wrong link. I have since fixed it, but that was two nights ago so you probably haven't seen it. And dang it this splash screen is too awesome to go unappreciated!!

Otherwise, we can consider this leg of the journey to be complete. That said, the adventure is only just beginning! Wouldn't be a Colossal Game Adventure with only one game, now would it? You can find the current schedule here. Our next destination will be Chrono Trigger with @ali stepping up as the next host. As for me, my time as conductor has come to an end and I will be joining you all as passengers.

If you intend to continue this journey, you can just grab your luggage from the—uh... *glances at the flaming wreckage* ...Well hey, it'll be a little easier to travel without all that extra weight, right?

Onwards to Chrono Trigger!

THE END

Hello everyone,

Gamers’ I need your advice. Due to a serious family illness, my nieces and nephews age 4 to 15 will be spending a lot of time at my home for the foreseeable future.

I also have a college age kid, who is home occasionally and will play a few sports games and fighting games. He is head of the Fighting Game club at his universities club.

I am looking to entertain the kids as we move towards winter and also keep my house in one piece.

I purchased a NS2 w/ Mario Kart World, Minecraft, Shinobi, SFVI, NBA 2k26, Star Wars Outlaws and BoTW.

I am going to purchase a few more Switch 2 titles and a few Switch 1 games. (Hopefully on a B2G1) sale. I do not need to purchase all at once. Likely, I’ll buy 1 or 2 a month. Or hope for a b2g1 sale.

I am LOOKING FOR RECOMMENDATIONS from everyone.

I already preordered Dragon Quest 1&2HD2D and Mario Galaxy 2.

Games I am considering.

Luigi mansion 3
Sonic racing Cross World
Persona 3 reload
Super Mario Bros U Deluxe (you can play as Peach?)
Mortal Kombat Collection
Madden or EA FC
Metroid Prime 4 ( I don’t know what to make of this game. Is it Metroid BoTW?)
Bomberman R
Paper Mario Thousand year door
Links awakening or echoes of wisdom?

I am looking to have some variety so there is something for everyone.

These kids already have a Switch 1 w/ mario kart 8D, smash, Mario 3d World, Minecraft and a bunch of Kirby games.

Any recommendations would be greatly appreciated.

Thank you in advance!

Side note: My kids had a Wii U when they were young and i am somewhat familiar with those games.

Kind of an awkward title, but I'm talking about settings for your phone, your OS, your coffee maker, etc.

With all the tech in our lives, and with so many devices and software having quite a robust set of options for how they work, it's easy for us to not even know that something is available. How many cool things are we missing out on if we're just accepting the defaults?

So, what's a setting, on anything you have or use regularly, that you recommend to others?

What makes it so worthwhile?

I have traditionally used APC's UPS products for my NAS, router, media centre and desktop computer. Nothing fancy, just something to survive short power outages and to allow graceful shutdowns if such an outage lasts longer than a few minutes.

Unfortunately, I have had three of APC's devices malfunction in the past decade and while their customer support has always been excellent, I would prefer products that just work and don't cause me additional headaches. Do you know of any UPSs that you would recommend for home use and are reasonably priced? I'm located in the EU, if that makes a difference.
