Explain to me why I, a passionate roboticist, am in this downward spiral of caring less and less about humanoid announcements.

One Halloween ago, I was testing robot teleoperation like this (sound on).
The experimental HF1 unit is still traumatized by its encounter with this hairy robot specter.
Happy Halloween!

Neo is ~30kg+payload. Should users let babies or small kids/pets near it (or the other way around)?
Unlike a piece of furniture, it must work constantly to keep its balance.
Unlike a person, its judgment is limited by current AI.
Imagine wet stairs or a stray Hot Wheels here⬇️

Everybody talks about AI agents for coding, but what about electronics design?
I’ve been using GPT-5 as assistant for that lately. Net-positive experience so far, but you have to stay vigilant.
Expect the following quirks / failure modes: 🧵

I don’t get why software folks say electronics is difficult. The only difference with software is that true constants don’t exist, your variables change with other variables in ways you didn’t intend, and a syntax error can destroy the computer or burn the building down.

I’ve been struggling lately to design a cost-effective new version of the robot’s PCB that can enable these improvements⬇️, but I think I’m finally pulling it off!
Wish me luck.

Don't be me and trace USB data lines first thing in your PCB.
They're a differential pair that needs to be designed carefully for robust transmission. Will likely make you move all other components out of the way.

Here’s the coding agent that BigCode doesn’t want you to know.
It’s incredibly predictable. If your prompt is specific enough it will do what you intend EVERY. SINGLE. TIME.
Software gurus call it “compiler”.

After talking with the Robotics Group of the University of León, Spain, I believe even more in the potential of HF1 as a robotics education tool.
Shout-out to the whole team for their warm welcome last Friday!

TIL last motor kits came with a different motor that draws 3x-4x more current. The peak starting motion drops voltage and turns off the Jetson.
Already started looking for alternative sources that can guarantee specs.
