@vincentslab @Venturi @coprod_Inc Hello Vincent, would love to chat about join actuator electronics. How can i reach out?

[mklb @mklb88]

1/
@asimovinc published the complete bill of materials for its open source humanoid.

Part numbers, ratios, torque constants, joint limits, friction. All 25 powered joints.

We mapped the whole thing and checked every number against the manufacturer. Five findings.

2/
Actuators are 35.5% of body mass. 12.43 kg on a 35 kg robot.

Five part numbers cover all 25 joints, split into two reducer families. Planetary where the joint moves fast and does work. Harmonic where it holds a posture without backlash.

3/
The ankle makes 145.4 Nm from two 36 Nm actuators through a parallel RSU linkage. Mechanical advantage of about 2.02 in pitch.

The joint inertia confirms it independently: both ankle axes carry exactly twice the armature of any other joint on the same actuator.

4/
Kt is published on the output side, so the current your power stage has to survive falls straight out. 10.5 A at the harmonic yaw joints to 43.6 A at hip pitch, on a 48 V bus.

Which kills the easy GaN pitch. At 48 V and 45 A, silicon is good enough.

5/
The one that surprised people: there is no motor drive line item in the BOM.

All 25 drives ship sealed inside the actuator housings. Total electronics budget $818.

If you build joint inverters, your customer is the actuator maker.

For those of us living in silicon valley - this speaks to the vast majority 👇🏼 and i recall Clara’s post on LinkedIn going viral when she first moved to the valley, how mega excited she was thinking she was up for changing the world. She just didn’t know what was waiting for her in here. It’s a builder’s wild wild west. In a way it’s humbling, and in many ways speaks to the requiem of the American dream.

[Clara Gold @Clara_Gold]

6 months ago, I moved to San Francisco.
It’s the best place in the world to build, and one of the worst places to stay human. My unfiltered take:

1. SF is both overhyped and underrated

The overhyped part: there are a lot of people with incredible resumes who are deeply unimpressive in real life. They were at the right company, at the right time, in the right market, and got carried by the wave. They made money, got comfortable, and now spend their time “exploring opportunities” over coffee, wasting your time.
The underrated part: the top 1% here is insane. But almost impossible to get. Hiring in SF feels like being a guy on a dating app: everyone you want is out of your league, and everyone in your league wants someone out of theirs. The best people have unmatchable packages, endless options, and are optimizing for maximum impact: labs, frontier companies, or startups raising $100M pre-seed rounds.
If you raised $10M from Tier 1 investors, you’re not hot shit here. You’re a B-player. It’s humbling.

2. There are fewer mission-driven people than I expected

Especially on the application layer. A lot of people are in “secure the bag before it’s too late” mode. And honestly, it gives me the ick.
The real religious builders I’ve met are often in labs, hardware, biotech, deeptech, defense — places where the work is hard enough that you can’t fake obsession.

3. The status game favors builders

This is what SF does better than anywhere else. It rewards obsession. It rewards weirdness. It rewards people who make building their entire personality. Europe punishes that. SF gives it status. If you’ve felt like an outsider your whole life because you care too much, work too much, think too radically, or refuse to be chill about things that matter, this city will make you feel less insane.

4. The market liquidity is absurd

Even if you don’t build a billion-dollar company, if you manage to build a strong product with a great team, someone smart might still acquire you for $ 100M. Yeah I know, it’s not your dream outcome as a founder, but on the days you feel desperate, it helps to keep going.

5. SF does not care about the meaning crisis that’s coming

Anyone paying attention here can feel that something massive is happening with AI. But I’m shocked by how little people talk about the meaning crisis coming next. Everyone wants to talk about AI liberating humanity. Almost no one wants to talk about what happens when work — the thing that gives most people identity, structure, dignity, status, and purpose — starts disappearing. The vacuum will not be peaceful. People are underestimating the chaos that comes from humans suddenly having no idea why they matter. And I really feel like no one cares.

6. Personally, I’ve never been more unhappy

I moved to SF and entered the matrix. I’ve always been intense. I’ve always worked crazy hours. But here, I lost the last parts of myself that were not about building.
I don’t go to events. Most networking events feel like theater for people pretending to be important. The only events worth going to are small, curated dinners with people who are actually alive. I’ve made 0 real friends. I don’t do well with transactionality. I don’t do well with people constantly performing greatness. I don’t do well with rooms where everyone is optimizing and no one is being honest.

So yes, SF is lonely, transactional, delusional, addictive, inspiring, boring, extraordinary, and completely insane.
But it is still the only place to be right now if you’re a founder trying to build the next wave of humanity.

And for now, that’s enough.

Yomif Kejelcha finished second on his marathon debut in 1:59:41, just 11 seconds behind. Both athletes ran virtually the same pace over the full 42.195 km and became the first to go sub-2 hours in an official marathon. Sawe was only approximately 261 milliseconds faster per kilometer than Kejelcha. Both ran at an average pace of approximately 2:50 per km.

To put this in perspective, data from Strava, Garmin, and large-scale running databases for adults aged 20–40 show:

• The average recreational runner sustains training and 5K paces of around 6:05–6:28 per km.
• Even dedicated amateur athletes (regular racers with 5K times under ~30 minutes) typically hold race paces of only 4:40–5:36 per km. More advanced amateurs do 3:30 - 4:00 min/km.

Sustaining 2:50 per km for 42.195 km is extraordinary. The vast majority of people including nearly ALL recreational runners and non-runners would be unable to maintain this pace for even 60 seconds (roughly 350 meters). Most average recreational runners would fatigue after just 100–200 meters.

An extraordinary display of elite endurance and pacing. #LondonMarathon

[Chris Chavez @ChrisChavez]

Here are Sabastian Sawe's splits en route to the 1:59:30 marathon world record. 🤯

He ran the first half in 1:00:29 and then the second half in 59:01. My goodness!

Splits — Time (Segment) — Pace (min/mile)
5K — 14:14 (14:14) — 4:35
10K — 28:35 (14:21) — 4:37
15K — 43:10 (14:35) — 4:40
20K — 57:21 (14:11) — 4:35
Half Marathon — 1:00:29 — 4:36
25K — 1:11:41 (14:20) — 4:37
30K — 1:26:03 (14:22) — 4:37
35K — 1:39:57 (13:54) — 4:28
40K — 1:53:39 (13:42) — 4:25
Finish — 1:59:30 (5:51) — 4:17

Just incredible.

They used to shame us for leaving the lights on in an empty room wasting energy. Twenty years later, tokenmaxxing means we’re microwaving Greenland so an LLM can generate a LinkedIn post about grit.

How times have changed.

[mklb @mklb88]

so unreasonable honestly. this is just a minor procurement corporate technicality. they already cut the check for the purchase order and accounting cannot invoice without some actual bombing for the receipts. with the ceasefire in iran they simply had to divert the leftover inventory to beirut so raytheon and lockheed can meet their quarterly growth targets. you are totally overthinking it and always blaming isahell for being predator bloodthirsty murder€rs

[Nassim Nicholas Taleb @nntaleb]

In the West, you see Israel through the prism of their unrelenting mendacious propaganda.

On the ground, you see it in its raw form: a vindictive, bitter, vicious, ungrateful, unreliable, perfidious, and, mainly, bloodthirsty terrorist state.

Enough, no?

Hey Leo, death and suffering are not happening in vacuum, so if you want to do something useful, perhaps you can name the victims and the predators instead of just praying for them @Pontifex

[Pope Leo XIV @Pontifex]

I continue to follow the situation in the Middle East with dismay. Like other regions of the world, it is torn apart by war and violence. We cannot remain silent in the face of the suffering of so many defenseless victims of these conflicts. What wounds them wounds all of humanity. The death and pain caused by these wars is a scandal for the entire human family and a cry that rises to God!

Love him or hate him, he’s dotting the i’s and dashing the t’s on the propaganda they’re feeding everyone. And the Zionist Economist so-called journalists can’t define a question they continuously ask, because their pea sized brains never questioned it themselves 🤡 and the circus continues 🎡
