Salute to a real robotics veteran. I can't imagine the hardware gore you have seen.

Absolutely, although it's a different ball of wax if you're trying to do RPO of this complexity with an adversarial body.

What software are you all using for kinematics and dynamics calculations?

Hey! Your Google Benchmark post was one of my go-to resources when I started picking that up a couple years ago. I love to see the focus on performance benchmarking here, and the repository is laid out well. Nice work!

Love the suggestion, I'll clone it down and start poking around. I believe your intuition about layout experiments needing to be of different genres is correct. I think you could have a pretty wide range of debugging opportunities (im

Fantastic idea. It seems like there are a lot of interesting experiments to be had here. The lab-play scenarios having a time-related component seems like a good idea, I assume most Factorio players that keep biters on treat them as a combi

Hugely bullish on the domain.

I'd imagine it runs the gamut. ROS for some older places; those starting fresh are probably doing ROS 2.

It sounds like your nephew has a project in mind. Start there with the basic dependencies and that will start laying out a competency roadmap which looks a lot like a curriculum. Quick aside: Automate small/mid business manufacturing?

I fell into industrial work right out of undergrad as a EE, not intending to work in the rust belt or manufacturing or anything of the like. I erroneously assumed it was not important, not sexy, not interesting. How wrong that was. How thin

Great links, thank you for this.

No kidding

I wonder if a mod that changes the graphics to a visual style shown in the link (I'm thinking the Carbot graphics [0] swap for StarCraft 2 in terms of scope) would make it feel more to your liking. [0] https://news.blizzard.

Thanks for refreshing and sharing this again! The visualizations are so similar to integrated circuit layouts; they immediately reminded me of some of the coasters that GamersNexus sell which represent simplified computer subsystems.

Having seen what some other university administrations have done to darling students and innovators even just around such things as lab space, parent comment is right on the money.

Congrats on the launch. How much did you learn from the lessons of other contemporary robotics frameworks that are out there? Do you envision focusing in on particular types of tasks later, or is it still uncertain how your robot design wil

Another HN roboticist chiming in; the videos look good! I have many questions, but will keep it to just a couple for brevity's sake. - How much are you able to use the robot's internals to estimate the gripped bag's inertial

Your story brought a huge smile to my face. Thank you for sharing, those kids are alright.

John Cleese as the bomb was a particularly fun role. This game just had a ton of personality.

Background: Started in industrial automation (lots of Fanuc, Yaskawa, Omron, etc.), built a lot of cool systems with cool people that made things with robots. Pivoted to "general" robotics in grad school. Been spending the last 5+

Because it is. There is an abundance of tutorials showing people how to get Gazebo simulations going, or set up a rudimentary classifier in Pytorch, or actuate motors with Arduino using whatever framework of the week (I even wrote some!). T

Another thing to note is that, depending on the standards (e.g. NFPA vs IEC), your control diagrams would be in horizontal [0] or vertical [1] format. So the typical left-right ladder flow you might see in RSLogix or something worked really

61131 has ladder logic, function block, and structured text, which is a pretty eclectic group of programming representations. I think about 99% of the PLC programs I saw were ladder logic, with the exceptions being Siemens pushing structure

I think you are right on the nose.

by spieswl 3y ago
Yep. Went from electrical designer in industrial automation from 23-27, went to graduate school, came out as a robotics software engineer from 29-onwards. Almost completely different worlds. About the only thing that was the same was the pr

Good luck and my condolences

As perhaps with some other HNers, I'm in specialized, technical line of work (robotics) and the SNR for most of content sources is absurdly low. There's just no way for me to put in a reasonable amount of curation effort for subje

I think the content of the article is totally orthogonal to the problem the title supposedly addresses. I was immediately excited to read this but then found no relation to what the article talks about. Content curation? Really? We're

Fascinating to see old-school automation meet new robotics more and more.
