- "Unfortunately the talkers are not the doers, and not the deployers, and not the people who have to solve real problems."
- Just published my annual predictions update, tracking from Jan 1st 2018, with new commentary and new ten year predictions. It is long. rodneybrooks.com/predictions-...
- It's end-of-year recap time again. If you'd like to know what I've been up to, want to read a tirade about overly complicated software, or both, then this might be for you. Enjoy the new year! roboticseabass.com/2025/12/27/2...

- ROSCon 2025 in Singapore is a wrap, and I am super happy to not have to do any work for a few days because it was a lot of preparation. I've written up a blog post with my experiences to share with all of you: roboticseabass.com/2025/10/31/r...
- I have a hard time dealing with people who make you feel bad/stupid for not knowing something they do -- whether intentional or due to poor social skills. As someone in tech, I should have already become desensitized to this, but I guess you can't just change how you feel.
- Doing a whole bunch of OSS pushes pre-ROSCon. I'm psyched up for now, but definitely looking forward to the break after the conference.
- I'm hiring for my team at the RAI Institute! If you're based in the US and are interested in working on robots solving complex, contact-rich, long-horizon tasks, do consider applying. jobs.lever.co/rai/db7d46bf...

- Absolute dumpster fire of a day. I've tried to do too many things, none of them exciting, I didn't do a good job at any one of them, and I'm too tired to form a coherent sentence. Sometimes you just need to take the L and try again another day.
- Pinocchio 3.8.0 was just released! I'm excited about this release because my feature (Viser visualizer) is included, plus there are a lot of fixes (especially to mimic joints) that came from issues I ran into myself. Open source is great. github.com/stack-of-tas...
- Such a weird positive feedback loop of people needing to signal themselves as pro-general purpose humanoid hype as possible, so their peers perceive their work as still relevant. Let's remember we're here to solve problems and/or uncover new understanding.
- Planning and control of high-DOF robots is a super interesting technical challenge. Making robots perform skills without hand-engineering point solutions is a super interesting research problem. Are these the most practical solutions to every societal problem? [citation needed]

- Does anyone know any experts in VR with an interest in immersive video streaming for teleop applications? If so, shoot me a note. Thanks!
- If I ever start using my free time to make thinkpieces instead of educating people, you may take me out back and put us all out of our misery.
- I'm back! Sorry, I had gone on a nuclear social media cleanse but then realized it's actually good to stay connected to people. Just need to do a better job curating.
