Introducing PRM (Physical Reasoning Model): a foundation model that infers and outputs an uncertainty-calibrated physical state from robot experience, so downstream policies can train on physics-complete signals — not just pixels and actions. @unsupervizedai @Ranita_Jana

Oh! that's a banger video! That's @narsagna This will go viral.
Less than a week to go to apply to YC W27 So here's a friendly reminder...

Just entered the US on my O-1 🇺🇸 Officially an Alien of Extraordinary Ability. Thank you @Ranita_Jana, @eliblee, @CharacterCap, and Bay Immigration Law for every bit of support. Let’s build the extraordinary humanoid the United States deserves. 🤖

Changi Airport needs more humanoids at work, especially in outdoor areas without air conditioning. The heat and humidity are brutal. Is it really humane to ask people to work in these conditions when autonomous humanoids could take on some of these tasks? Imagine a fleet of 100,000 autonomous humanoids at Changi. It could transform how the airport operates - and redefine what airport services look like in the future. Humanoids for humans. #HumanoidForHumans @ChangiAirport
#NEW: Jewel Changi Airport is in full bloom this June holidays 🌸🌿 From blooming displays to photo-worthy corners around Canopy Park, it’s a must for flower and LEGO® lovers. Read more: brnw.ch/21x2Pt9 #JewelBloomswithLEGOBotanicals

Do get it, where it is going!
The most important, yet most undervalued and underappreciated opportunity in robotics is building a context layer for deployment.

It seems Zuck is having more fun here, than his own backyard. @elonmusk let than sink in.

Now, our robots are running in warehouses across America, doing valuable work for customers every day. Ultra’s mission is to build the world’s most useful and deployable robots. And we’re just getting started.

This is where egocentric data scaling is leading to a pricing war. I guess most of these companies will be from South and Southeast Asia. But @calixo888 is EgoData actually improving the models? Is there any specific model that relies heavily on EgoData and is showing strong generalization?
Replying to @calixo888
After multiple iterations of hardware, firmware, and software, we scaled our pipeline and headcount. All-in cost dropped from $72 to $10 per hour of footage at scale, compared to our vendor quotes of $60–150/hr.

Hey @grok what do you think, is it tele-operated or autonomous completely Unsupervized.
Robot puts a ring on it GEN-1.5 puts an O-ring on a hydraulic rod gland, then takes the ring off, then puts the ring back on, then takes the ring off, then ring on, ring off, ring on... Read more about GEN-1.5 in our blog post in the comments below.

This is a very interesting concept!
update on compliant gears: uhh amazing?

Glimpse of the wonderful robot that we have built!
Humanoids are coming into our workplaces and homes. To truly belong there, they must understand the physical world and work hand in hand with the people in it. Meet CoPAEI a.k.a Collaborative Physics-Aware Embodied Intelligence.

Humanoids shouldn't need a nine-figure budget. Meet CoPAEI: an open, modular humanoid platform, made in the USA. Founding Cohort now open: 10 institutions, 2 robots each. Request access: copaei.usvz.ai Grateful to @CharacterCap @sachgaur for backing us early.
We built a humanoid robot platform called CoPAEI, a physics-aware, modular, and easy-to-repair humanoid designed to help scale humanoid robotics across America.

Super cool!
ETH Zurich researchers trained a robotic hand to use its five fingers as legs for untethered locomotion, with onboard power, sensing, and computation. Reinforcement-learning policies enable the system to crawl, steer, recover from falls, and adapt its locomotion across 14 indoor and outdoor surfaces, including carpet, tile, asphalt, grass, and gravel. The hand can also perform keyboard presses while supporting its own weight and use overhead visual feedback to push objects toward target locations.

Congratulations @drfeifei and @LisaSu
We are excited to announce that World Labs is joining @AMD. The research and technical breakthroughs we have achieved since our founding in 2024 have given us a clear vision for AI’s potential to solve problems in the spatial and physical world. Accelerating the future of spatial and physical intelligence requires scaling our efforts, scaling our reach, and getting closer to the hardware.

일본이 산업용 로봇 감속기 세계 60%를 쥐고도 휴머노이드 액추에이터에선 압도를 못 하는 이유, 엔지니어TV가 깔끔하게 정리했음. ▍기준이 바뀌었음 · 산업용은 바닥에 고정된 채 정밀도, 강성, 내구성 싸움. 나브테스코와 하모닉드라이브가 수십 년 쌓은 장벽 · 휴머노이드는 자기 몸을 들고 걸어야 하는 물건. 토크밀도, 출력밀도, 반응속도가 새 기준 · 발목에서 몇백 g 줄이는 게 관절 하나 문제가 아니라 로봇 전체 무게와 배터리 문제 ▍구동 방식도 교체 중 · 작은 모터에 감속 크게 대신, 큰 모터에 감속 작게 가는 QDD. 사람 근육처럼 힘을 직접 전달 · AI가 아무리 좋은 판단을 해도 관절이 늦게 반응하면 소용없어서 반응성이 핵심이 됨 ▍진짜 병목은 가격 · 야스카와 25kg급 로봇 한 대가 $40,000~58,000, 정밀 감속기 하나가 145만~580만원 · 산업용은 축이 6개인데 휴머노이드는 관절이 수십 개. 이 단가 그대로면 로봇이 수억원 · 결국 승부처는 작고 강한 액추에이터를 싸게 대량생산하는 능력 경쟁 단위가 감속기 단품에서 통합 관절로 넘어가면 정밀부품 장인보다 대량생산 체계가 유리해짐. 한중일 3파전이 되는 순간, 한국 제조업이 일본 아성을 정면으로 칠 수 있는 판이 처음 열리는 거임.
