Friends, what do we think about a robot that does tiling? (You know… bathrooms, kitchens, etc)

Benchmarks in sim is not the same as benchmarks in robots.
They did WHAT to robotics?!

Replying to @claudeai
Fable 5.2 shows substantially improved skills in controlling physical robots, even on tasks it has never explicitly been trained to do. On RoboDojo, a benchmark with a simulated two-arm robot, it outperformed other models and most AI systems built to control robots.

The cheat code to startups is delusional confidence No traction. Ugly metrics. Investors passing. Everyone says it won’t work You still believe you’ll figure it out Not blind to reality. Just sure you can change it. Before product-market fit, you look insane After, obvious.

Everyone building the “physical AI platform” seems to be leapfrogging the whole “we don’t REALLY know what the future will look like.” Seems like extreme “cart before horse” at venture scale. I know a ton of robotics founders and I can count on two fingers how many of them “struggle” with fleet deployments, telemetry, etc. Multi million dollar “cloud management” startups made sense AFTER there was billions of dollars of cloud infrastructure. If I were a betting man, I’d bet on deployments as the first class (and maybe only?) metric. The “but can it do other things” and “but how does it work at scale” WILL be solved by deployments. Those questions are often viewed as barriers, but they’re entirely the wrong question.

Genie 4 is wild, and a world you can poke in real time is a big deal for training robots. But robots don't care how good the rain looks. They care whether the box slips when they grab it.
This is Genie 4, our most realistic and interactive world model yet. 🌐 Explore dynamic environments in real time to see how the scene responds, sounds, and how the people in it move, react, and speak.

A union installer expected "just a little helper carrying a pallet." Then Tyler started setting tile. @Shamoons shared the story at @StarnetFlooring 2026, plus how one installer went from 100 to 800 sq ft a day with @HFRobots. Thanks Mark Bischoff for having us. Full talk below 👇

The list of jobs people swear can't be automated keeps getting shorter. Fun watching another one come off it lol
When we started @SereactAI , people told us returns were impossible to automate. This is Cortex handling @Zalando returns at a @cevalogistics fulfillment center. It’s live and in production, every shift. Proud of the team that made this real.

Glad someone finally wrote this up! The most useful data on a jobsite is every time a person had to step in and fix what the robot did. A demo never shows you that part
One question I get from business owners all the time: How to turn everyday work into robotics training data? Now, I finally write an article about that. The best way to "catch up" on the physical AI transformation is to embrace it.

Q: How much hook-and-loop/Velcro material is securing cables in the world’s data centers? 🧐 A: Some fuzzy math: 34 million racks × 100 strips per rack × 30 cm per strip = about a million kilometers. That’s 25 times around the earth’s equator! Or 1.3 trips to the Moon and back! 🌙 TODAY our partners at Velcro Companies visited the Human Friendly Robotics office to oversee development of TREY, our overhead cable tray organizing robot for data centers. 🤖 The need for securing Velcro ties quickly and autonomously, without sending a guy up into the air dozens of times. Hey Velcro folks! Great having you over. See ya’ll next week to demo at Mortenson!

Totally true for software. The physical world is still missing a few bricks tho. The internet never recorded what it feels like when a bolt starts to cross thread
LLMs are magical alien technologies we’ve managed to conjure up from a distillation of the internet. Even if progress completely stalls, we have years worth of value to harness from what we already have. In other words, these lego bricks still haven’t been put together in the most obvious combinations.

Cheap text is great, but machines never really made it out of the factory. Building a house or pulling wire looks alot like it did 50 years ago, and construction productivity has actually gone down since 1970. Cheap houses and infrastructure is the abundance I'm most excited about!!
1. Humans will not stop creating text, images, and music. We will always do this for joy and self-expression. 2. AI will create most content in the future, and it will displace many humans doing so, just as machines did for physical products. The result will be an abundance of affordable, high-quality text, images, etc. for everyone to use and enjoy. 3. You might be sad about this. I won't tell you that you are wrong, because I don't police people's feelings. Regardless, this transformation will be, on net, a very good thing. I understand if it's emotionally hard to process, though.

The electrician premium is the one I'd bet sticks around even if the boom cools. Chips and turbines can add capacity. A journeyman electrician takes 4-5 years to train, and a lot of them are retiring. Labor stays tight, so automating the repetitive parts (pulling wire, terminating, testing) pays off either way.
The AI boom has created insatiable demand for data centers. Nobody knows how long it will last. Everything that goes into data centers, from cement, to the labor that builds them, to the electricity that runs them, to the chips that provide their intelligence, is overpriced by a large factor. Gas turbines are on track to triple in price from 2019 levels. An electrician wiring a data center makes about double what electricians make everywhere else. Nvidia sells its chips at a 75% gross margin, as if it were a software company. Companies making these investments are drawing straight lines into the future.

Big congrats to the Skild team!! Abhinav's line about revenue over demos and free POCs should be pinned in every robotics startup. A free pilot proves the robot can do the task. A paid one proves the customer thinks its worth doing. Next number I want to watch: how much human help each robot needs as the fleet grows.
Thanks to @Nasdaq for celebrating our 100M ARR milestone in Times Square.

Best line in the Pi API writeup: construction, surgery, warehouse automation 'each requires an entire company.' Pi makes the model layer shared. The robot company still owns the hardware, the task, the recovery when stuff goes sideways, and the customer paying for it to work every shift. And the loop they describe is the real unlock for small teams: collect demos, fine-tune, run it, let the failures pick the next data. Almond got a deburring policy in 4 days of iterating. Also an autonomous wheel loader in commercial use with nobody in the cab. Love seeing construction on the list!!
Announcing the beta release of the Pi API. We’ve partnered with companies across diverse industries to adapt our models to their robots and applications, from harvesting strawberries to assembling servers. Now we’re opening access to more teams.

Fun detail on how Kaiser actually hit that rate. They built deckhouses and hull sections upside down in a separate prefab plant, so most welding was down-hand, the easiest position. Newcomers got placed right away and could make journeyman in a few months. Average Liberty ship went down to 42 days. Same playbook works for robots in construction and factories imo. Change the job so new hands (or simpler machines) can do it. Nobody went looking for more master welders.
150 GW of new production brought online over 20 years, or 7.5 GW per year. Most of it would be wind power. Offshore turbines currently generate about 25 MW, so they would have re-industrialized Glasgow's dockyards to produce about one per day. This is about the same rate that the Kaiser shipyards produced finished liberty ships, which are substantially more complex. One turbine per day doesn't sound like all that much, but do it for a decade and Britain doubles its power production capacity. Or stay poor forever.

Wild that the whole room landed on the same thing. If the brain gets cheap, the value moves to everything around it. Does the robot know the job actually got done? Can it back up and retry when it didn't? Who shows up when it gets stuck at 2am? Demos get to skip all of that. Curious how many times per shift someone has to step in on the real deployments.
sat in a room full of robotics founders in SF tonight. everyone agrees VLAs continuously fail, so real deployments rely on reasoning models and vision. most demos can be vibe coded on GPT 6.1 Sol every company has the same progress. only the ones in the media look ahead.

Feedback is only useful if you know how old it is. By the time a robot acts on a camera frame the world already moved, and force/torque comes in way faster than vision anyway. Love seeing time treated as a real input!!
Most robot policies treat time implicitly, using sequence position as a proxy for physical time. But real robot systems rarely run on a fixed clock. Sensors run at different rates, observations arrive with delays, and actions take time to compute and execute. Successful control depends not only on what the robot observes but also on the timing of observations and actions. We introduce 🕒 Chronos Policy, a diffusion policy that explicitly conditions on observation capture times and requested action execution times. We use time-aware positional encodings to make attention depend on elapsed physical time. Because timestamps let the policy interpret each sequence's timing, we can randomize sensing and action timing during training without making those variations ambiguous. This exposes the policy to a wider range of timing conditions, improving robustness to timing changes at deployment.
