I mentioned there was more exciting stuff to come after SGS 😀. @octi_zhang's latest work shows the kind of incredible emergent behaviour we can get from large scale RL in simulation. I've been applying these same ideas to other tasks, and have seen impressive results already!
(1/6) From @GoogleDeepmind’s AlphaGo to AlphaZero, we saw machines find moves that reached beyond what we’d imagined for them. No one taught them those strategies. They emerged from reinforcement learning: playing, failing, and trying again under a single binary task reward for success or failure. Inspired by them, we couldn’t help but wonder: what might a robot discover if we gave it that same freedom to learn? That question led us to AlphaNIST. Starting tabula rasa, with that same binary reward plus only a simple control cost, a single policy solves all 20 @NIST assembly tasks at a 98.2% success rate in simulation. More surprising still, AlphaNIST can complete 10 different tasks in a row, receiving that reward only once, after all 10 are done. Just as AlphaGo’s strategies surprised its creators, AlphaNIST discovered dexterous strategies we couldn’t have come up with ourselves. Paper: arxiv.org/abs/2610.13354 Website: alpha-nist.github.io

The value of scaled RL training in simulation can't be understated. Huge congratulations to @octi_zhang and everyone else who worked on the SGS paper. What comes next is even cooler - stay tuned!
(1/5) Everyone says dexterous manipulation needs real-world data. These policies were trained with none. Our robots mesh gears, thread nuts, and insert pegs zero-shot from RGB, and the same recipe works for locomotion across terrains much harder than before. The missing piece wasn't a better RL algorithm, but a small tweak to what the robot practices. Today we're releasing Success-Guided Sampling (SGS), a simple change to the task sampler that unlocks new levels of dexterity and agility with large-scale, end-to-end sim2real RL. No demonstrations, no per-task reward tuning. Just PPO at scale. Check out the policies yourself at sgs-rl.github.io! All videos at 1x speed! 🧵 🔈

Fantastic work by @jayjunleee and the @NVIDIARobotics Dex research group. Always great to see new foundational sim2real work leveraging Isaac Lab!
What if robot hands could acquire dexterity once, then reuse it to learn downstream tasks much faster? Introducing ADEPT: a pre-training & post-training paradigm using RL entirely in sim, then zero-shot deploying visuo-tactile policies in the real world. 🔗adept-dexterity.github.io with Dex team @NVIDIAAI

So cool! Just ordered mine! Any chance you guys will release the Isaac Lab training setup and USD models? Even better to be able to update the model on the robot…
Mondo's Beni (mondorobotics.com/) may look cute, but there is a serious learning stack inside. It can perform flips, navigate autonomously, and track moving subjects. The secret is reinforcement learning: Beni practices at massive scale in simulation, optimizing its controller through millions of virtual trials before entering the real world. Here is a thread on some of the research ideas and tools used by Beni: 🧵

How can robots learn dexterous manipulation from human demonstrations at scale? Excited to share CHORD: Learning Dexterous Manipulation Using Contact Wrench Guidance From Human Demonstration. CHORD learns from human demos by focusing not only on where contact happens, but how that contact moves the object through force and torque guidance. This unified contact-wrench representation carries human manipulation skills across diverse behaviors, long-horizon tasks, whole-body embodiments, and real-world hardware. We evaluated CHORD on large-scale, long-horizon, contact-rich tasks paired with human demonstrations, spanning rigid, articulated, and multi-object manipulation. At scale: * 82.12% average success across 1,831 tasks * 90.77% whole-body manipulation success * 4,739 sim-ready dexterous manipulation benchmark * Transfer to real dexterous hands Project page: nvidia-isaac.github.io/video… Tech report: nvidia-isaac.github.io/video… Code will be released soon as part of Video to Data repo github.com/nvidia-isaac/vide…, our end-to-end pipeline for converting human demonstration videos into simulation-ready assets and physics-grounded robot training data.

Robots assembling robot brain -- imagine this kind of robustness on every precision manufacturing line! Live demo of GPU rack assembly at #NVIDIAGTC: - end-to-end neural network (Skild Brain) finetuned with little data - memory to perform long horizon task (placing jigs, 16 screwes, removing jigs) - robust to disturbances and fast to set up - no fancy sensors, just off-the-shelf arms and cameras
Nearly every system today, from energy to chips to food, is bottlenecked by scarce human capital. We are changing that by building AI-powered industries of the future. Check out Skild Brain robustly assembling GPU racks, a highly precise task, live at #NvidiaGTC.

Excited to share the project that has surprised me the most in the last year! Large-scale RL in simulation, no demos and no reward engineering can solve dynamic, dexterous and contact rich tasks. The learned behaviors are reactive, forceful and use the environment for recovery in ways that are extremely challenging to bake in or teleoperate! You can play with the policies yourself to see: weirdlabuw.github.io/omnires… And, the learned behavior transfers to real world robots from RGB camera inputs! So what’s the trick - using simulator resets carefully! Let’s unpack (1/10)

We have seen rapid progress in humanoid control — specialist robots can reliably generate agile, acrobatic, but preset motions. Our singular focus this year: putting generalist humanoids to do real work. To progress toward this goal, we developed SONIC (nvlabs.github.io/GEAR-SONIC/), a Behavior Foundation Model for real-time, whole-body motion generation that supports teleoperation and VLA inference for loco-manipulation. Today, we’re open-sourcing SONIC on GitHub. We are excited to see what the community builds upon SONIC and to collectively push humanoid intelligence toward real-world deployment at scale. 🌐 Paper: arxiv.org/abs/2511.07820 📃 Code: github.com/NVlabs/GR00T-Whol…

This journey started for us attempting reconstruction of multicamera AV scenes with huge photometric differences like the one below. We wanted a principled way to handle ISP effects in #3DGS, which became PPISP. Big congrats to Isaac Deutsch, Nicolas Moenne-Loccoz and @ZGojcic !
📢 We introduce PPISP, a physically plausible camera module for Gaussian Splatting that reduces floaters under varying appearance and predicts camera corrections for novel views such that they closely match what a real camera would output. #CV #3DGS
