Mission Success!

GSLV-F17 has successfully accomplished its mission, placing EOS-05 into the intended orbit.

Sharing a few memorable moments from the lift-off.

SO-ARM 102 goes open source in September.

- A parallel gripper, so the jaws stay parallel through the whole stroke instead of rolling the object as they close.
- PET-CF instead of PLA+, for a much stiffer frame.
- A topology-optimized structure, which is where the lattice in the video comes from.
- Wider rotation and folding angles.
- STS 3250 servos.

Against SO-101 that adds up to 2.5x payload, roughly 2x positioning accuracy, roughly 1.6x movement speed, and about 36 mm more reach.

It runs on Hugging Face LeRobot, so datasets, policies and tutorials written for the platform work on it from day one. The pair in the video shows why that matters. You move the leader by hand, the follower copies, and what comes out is a recorded demonstration a policy can learn from.

Everything goes public in September.

Walks, sits, roller skates, grabs objects with its beak, gets back up on its own. Out of the box.

Introducing S1, our new foundation model that learns from one example.

It can be taught 10-minute long tasks that it has never seen before, from one video prompt without any fine-tuning.

Watch S1 operate in real-time via in-context learning:

[Jim Fan @DrJimFan]

The sense of touch is the most criminally under-explored modality in robotics. Imagine doing sleight of hand wearing thick oven mitts. That's exactly how a robot feels today if it were alive. A magnetic piece snapping into place, a paper cup peeling out of a stack, a USB negotiating its way into the port - all invisible to the camera.

Learning how to feel must be a full-stack co-designed effort. We are open-sourcing a principled methodology called "T-Rex":

1. Tactile as first-class citizen of the model. Our mixture-of-transformer runs two clocks asynchronously: a slow visuomotor expert plans the motion, and a fast tactile expert refines it in real time with high-frequency corrections at 4 "touch ticks" per vision tick. Forces change faster than frames arrive, so the architecture had to as well.

2. Open data. The largest tactile dataset ever released to our knowledge: a 50-hour (~5,500 episodes) high-quality, carefully synchronized robot play corpus, collected on SOTA tactile hand hardware with 22 degrees of freedom. Available today on HuggingFace!

3. Training recipe: T-Rex extends our prior work, EgoScale. Human egocentric videos for pretraining, a diverse dose of tactile robot play for mid-training. Our experiments show this bridges contact-free pretraining to contact-rich manipulation remarkably well.

Pixels are cheap and everywhere, but they run out of steam at the moment of contact. Tactile will carry the last mile. The next scaling curve will be measured in hours of touch.

T-Rex is a great collaboration between NVIDIA and Berkeley: 🧵

100,000 hours of human hands doing real work. LeRobot format, fully annotated and open.

EgoSuite-Open100K from @LightwheelAI X @huggingface: 15,000+ tasks across 15,000+ real scenes, hand + body pose and wrist cams.

Recorded across 7 environment categories and 128 scene types, from kitchens and bedrooms to warehouse floors and assembly lines.

It's open for academic research and commercial training, and streams straight from the Hub. Always great to see a dataset at this scale released openly on the Hub.

ego-to-robot data pipeline is one key component of Qwen-RobotManip （https://t.co/0JZxVfWlqq）

Today, we’re sharing the full technical details behind it: Ego2Robot 🤖
It turns egocentric human videos into scalable robot training data and improves VLA generalization across tasks and embodiments.

What do you do with 16TB of pure robotic manipulation data? 🤖

You open source it on @huggingface
Simple World Lab just dropped HiFi-UMI-2K - an absolutely massive dataset pushing the limits of high-fidelity manipulation.

The entire 16TB is already available in the LeRobot format, meaning you can plug this massive scale straight into your pipelines with zero friction.

Breaking: At times a miracle happens. Got PCR kits - substantial- thank you #SIEMENS. I must thank my incredible team for persuading relentlessly. This tweet is purely for benefit of my peers.
I believe #SIEMENs have unblocked major bottleneck in #COVID testing.

Update on the affordable Respirator which we hope will be invaluable in early & recovery stages of the illness.The team’s included several features such as variability controls, sensors & emergency shut-off based on advice from https://t.co/fPKr78ETvb on the packaging continues..

[Ashwin 🇮🇳 @ashwinravi99]

Hahaha, somebody sent me this and told me it's exactly been 1 year since this run out happened.

As the nation goes into a lockdown, this is a good reminder to my citizens.

Don't wander out. Stay inside, stay safe! #21DayLockdown

[Narendra Modi @narendramodi]

By converging around shops, you are risking the spread of COVID-19.

No panic buying please.

Please stay indoors.

I repeat- Centre and State Governments will ensure all essentials are available.

[Commissioner of Police, Greater Mumbai @CPMumbaiPolice]

Namaste, I’m the Commissioner of @MumbaiPolice & this list has definitely not been made on my directions! The last thing we want to get infected with & pass on during such crisis is rumours. Pls verify every msg regarding emergency services before you forward #StaySafeFromRumours

[Narendra Modi @narendramodi]

Stay at home and do not step out until it is absolutely essential.

I specially urge the elderly to not venture out of their homes. #IndiaFightsCorona
