I build robots!

spieswl··on A non-mathematical introduction to Kalman filters for programmers
Probabilistic Robotics should be required reading for most robotics engineers, IMO. Great book.
spieswl··on ROS 2 Iron Irwini Release
So many of these comments sound like engineering process flaws.

Everyone's working on their own ROS nodes in isolation....with no thought to eventual integration testing? It doesn't seem like that is a fundamental shortcoming specific to ROS.

spieswl··on Remote work brings hidden penalty for young professionals, study says
I have found that is a pretty good signal for how an organization's culture is set up in regards to helpfulness and camaraderie.
spieswl··on My Failure Resume
I felt the same. The presentation is innovative and impressive (for sure a SUCCESS), but I do not feel like there's anything broadly meaningful in the content and the whole thing feels like a massive exercise in namedropping.
spieswl··on Alphabet’s Intrinsic Acquires Majority of Open Robotics
It boggles my mind that more people aren't talking about this.

I work in robotics and seeing an Alphabet moonshot come out of nowhere to take a controlling interest in OSRC is fascinating. Even validating for those who are working on enterprise-focused solutions for robotics makers and integrators.

It seems to me that Intrinsic (and probably Alphabet as a whole) are getting wise to the big uptick in commercial robotic services that we are going to see over the next couple decades.

spieswl··on Launch HN: Charge Robotics (YC S21) - Robots that build solar farms
> The standard PV connectors today are comically bad for handling by robots, dangling loosely from wires on the back of the module.

Yeah, I made some machines that attached those harnesses in a prior life. My condolences. ;)

> There's enough hands-on work involving the robot that we aren't quite ready to bring on full-time remote workers yet. As we grow, this is something we will become more open to.

Not unexpected, but still sad. That said, I love what you all are doing and will keep you in mind!

spieswl··on Launch HN: Charge Robotics (YC S21) - Robots that build solar farms
Very cool. Great to see fellow robotics starters on HN! How are you connecting the solar modules, electrically?

Also, I didn't see on your page anything about remote work. I understand why that might not be in the cards for robotics work, but is that the case for Charge?

spieswl··on But life had other plans
That is an incredible story! Best wishes to the family.
spieswl··on Best RealSense replacements?
Incoming hearsay, but I've heard conflicting things from RealSense integrators on what Intel is actually doing with this product over the longer term. Someone mentioned that ongoing R&D is being shuttered, but the depth camera product would still be available for purchase for a while. It would be nice to get some more clarity on what's actually happening.
spieswl··on Show HN: Web-based visualization for robotics and autonomous vehicles
This looks awesome! I didn't see this in the README, but does this gracefully handle ROS bags that aren't properly indexed?
spieswl··on Seven Years of Factorio Friday Facts (2020)
Absolutely. I'm a sucker for good writing and I feel that you all set an excellent example of how to do technical writing and analysis correctly.
spieswl··on Seven Years of Factorio Friday Facts (2020)
Author here. Wow, uh, I definitely did not expect to be featured on HN this morning, but seeing this linked put a massive smile on my face.

There are just so many examples of captivating writing, innovative problem solving, and candid discussion throughout the FFFs. Taken all together, the Factorio journey is one of my favorite _stories_ to read...and it contributed to becoming a better designer and engineer along the way. I really encourage people to read more of their blog than just what I've linked, since it crosses so many areas of interest.

To anyone reading that's worked on Factorio, thank you and you all are wonderful people.

spieswl··on Launch HN: GreaseBoss (YC W21) – Real-time system to manage industrial greasing
HaaS is definitely a thing. PMaaS, as well! (Preventative Maintenance)

I know a number of industrial robotics manufacturers have been pushing data-driven preventative maintenance initiatives. Ideally (for the manufacturer) this work is performed by the manufacturers techs during scheduled operator downtime, including the lubing of mechanical systems.

Have you all thought about presenting an alternative arrangement for the lubrication responsibilities of specialized systems, like industrial robotics, that might already have maintenance responsibilities (possibly contracts) in place?

spieswl··on State of Industrial Robotics: Emerging Tech, Challenges, Key Research Directions [pdf]
Disclosure: Previously worked for an industrial automation integrator and currently work for a robotics startup.

Weird paper. Reads like a survey of the state of the art from a decade+ ago. Many of the things mentioned are already mature areas of focus for startups and major players in the industrial robotics space. Many startups are working on the portability, ease-of-integration, and ease-of-use problems [0][1]. Cloud-oriented tools tailored to robot, line, and facility level health-and-status monitoring (even beyond the capabilities typically provided by SCADA systems) have been available to buy from major players for a long time [2]. I know Big 3 automakers have been toying around with integrating collaborative robots for years (and another OP already mentioned Rethink). Simulation tools run a pretty wide range of usefulness and market penetration, from first-party tools like ABB's RobotStudio or Fanuc's ROBOGUIDE to tools in the ROS stack to Nvidia's ISAAC simulator [3].

To be fair, I only scanned it but I did not detect the hints of anything useful except for those who are entirely unfamiliar with the industrial manufacturing and robotics space.

spieswl··on Cincinnati is home to the largest unused subway system in the world (2016)
Cool to see a weird piece of history from the hometown on HN. Many of those tunnels were used to run utilities and fiber so they still have usefulness, but it is sad to think about "what could have been" if many American cities had gone further with these kinds of projects.
spieswl··on Setting up personal OKR (objectives and key-results)
That last statement is crucial.

I was surprised to see how in-depth and detailed these objectives are. Not to knock the author, mind you; the dedication to breaking these things into granular tasks is impressive. Rather, I feel that there's little room for flexibility in taking an OKR approach to personal development.

Case in point, I had a personal objective to do more service in the community in 2020. The way I had envisioned the key results was more volunteering, more interactions with people, more things like spending weekends working on a Habitat for Humanity house or something of the like. The pandemic really disincentivized those kinds of in-person activities for the sake of the community, so I pivoted to identifying more causes I could donate to or provide help to in remote ways. It was hard, no doubt, and I was still disappointed that I didn't get to do the former things, but considering the circumstances it _feels_ like my original objective was achieved. The takeaway is that I think personal objectives that leave little room for flexibility are fighting an uphill battle from the start.

spieswl··on $100 robot kit running ROS2 and Navigation2
This is one of the best primers / courses in ROS around. Start at the top and just go straight down the list in the first section. Most of section 3 is unrelated to the ROS content and is general dev reference.

spieswl··on PlotJuggler 3: fast and intuitive time series visualization
An invaluable tool for analyzing data in robotics! Pretty much everyone I know who works with ROS has used PlotJuggler at least once.
