NVIDIA's new CHORD framework teaches robot hands to manipulate objects by matching how human contact moves an object. Learned from human demos and transferred to real dexterous hands. Look at the high success rates: 82.12% success across 1,831 contact-rich tasks; 90.77% success on whole-body manipulation. With policies deployed from simulation. That's the #SharpaWave in the loop :) Project: nvidia-isaac.github.io/video_to_data/… Paper: nvidia-isaac.github.io/video_to_data/… #PhysicalAI #DexterousManipulation #RobotLearning #NVIDIA #EmbodiedAI #Robotics #Dexteroushands

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_to_data/… Tech report: nvidia-isaac.github.io/video_to_data/… Code will be released soon as part of Video to Data repo github.com/nvidia-isaac/v…, our end-to-end pipeline for converting human demonstration videos into simulation-ready assets and physics-grounded robot training data. Huge thanks to amazing contributors: @zhu_xinghao , Zixi Liu, Shalin Jain, Chenran Li, Milad Noori, Huihua Zhao, John Welsh, @michaelv03, Wei Liu, @TingwuWang , Xingye (Dennis) Da, @zhengyiluo, Vishal Kulkarni, @sNaema, @yukez, @DrJimFan, @bowenwen_me, @danfei_xu, @SohaPouya, @Dr_YanChang. #Robotics #PhysicalAI #DexterousManipulation #RobotLearning #NVIDIA

Before a robot can perfect assembly, it needs to learn to play. The team behind SimToolReal @kushalk_ @tylerlum23 @leto__jean @KarenJLiu published another cool paper! Play2Perfect pretrains on diverse, task-agnostic play (grasp, reorient, reach, etc), then finetunes on sparse-reward assembly. Result: 33× sample efficiency vs. training from scratch, and zero-shot sim-to-real down to 0.5mm clearance. Peg insertion, screwing, multi-part assembly: all running at 60Hz, real speed, real hardware. And when a grasp slips, the policy doesn't stop, it recovers and keeps going. The Sharpa Wave responded present again ;) Project: play2perfect.github.io #Robotics #SharpaWave #Sharpa #EmbodiedAI #DexterousManipulation #RobotLearning

What if the next leap in robot manipulation comes from touch, not just vision? To get there, foundation models need to understand tactile feedback the way they understand images and language. And tactile policies cannot be locked to specific hardware (that makes real-world deployments & maintenance quite complicated). FTP-1 solves both. One of the 1st foundation model for touch. 21 sensors. ~3,000 hours of data. Transfers to hardware it has never seen before. +17% on known hardware. +31% on never-seen hardware. We're proud this research led by @michaelyuancb ran on #SharpaNorth, #SharpaWave hands, and our DTC sensors. Special thanks to the teams at @Tsinghua_Uni , @UCBerkeley , @ETH , and @sjtu1896.

North recently tried ironing. This week: shirt folding. 👕 Unlike ironing, folding is a skill even the most reluctant of our engineers have mastered. Notice how smooth the hand movements are. Clothes deserve some respect. 😉

One of the underappreciated factor in learning dexterity from humans is the hardware – imitating humans the way we did would be much more difficult if we didn't have a roughly human sized hand. Thank you @SharpaRobotics for your support!

We can use videos from the internet to teach robots! Do as I Do, from @bhawna_paliwal_ , @HarithejaE , and Willian Liang at UC Berkeley — advised by @pabbeel, @notmahi, and @JitendraMalikCV, used an algorithm that reconstructs hand-object interactions from monocular RGB video and retargets them into real, executable trajectories for multi-fingered dexterous hands. Just using "low quality" video footage of humans doing tasks. No sensors. The Sharpa Wave robot hand being anthropomorphic, it matches human kinematics. Not only that works, but at fast speed, too! Congrats to the team, that's super exciting! Project: do-as-i-do.com #Robotics #SharpaWave #Sharpa #EmbodiedAI #DexterousManipulation #RobotLearning

The dataset was collected using two Sharpa Wave hands, using our high-resolution Dynamic Tactile Arrays on each fingertip to capture the dynamic touch signals needed for contact-rich manipulation. T-Rex proves that anthropomorphic hardware and tactile-reactive software are co-dependent :) Amazing work @Dantong_Niu ! P.S. The Wave's Isaac Sim URDF/USD assets and tactile parameters are available here if you wanna take a closer look: sharpa.com/pages/downloads

Robots need to feel the world to operate in it. Most manipulation policies today are tactile-blind. They either cannot interpret high-frequency tactile signals or treat them as a static channel. And the field lacks enough touch-rich datasets to train tactile-reactive policies at scale. T-Rex was built to answer both. @Dantong_Niu and team, advised by @DrJimFan, @drfeifei, @JitendraMalikCV, @pabbeel @trevordarrell have tested whether a robot policy can react to high-frequency tactile signals the way human hands do, without giving up the generalization power of modern VLAs. The result: 65% average success rate across 12 real-world tasks. +30 absolute points over the strongest baseline. In one year, tactile VLAs have gone from promising to outperforming non-tactile baselines like pi0.5 on dexterous tasks. #Robotics #SharpaWave #Sharpa #EmbodiedAI #DexterousManipulation #TactileSensing #RobotLearning Project link: tactile-rex.github.io

4/N: Why motor primitives? A key design choice behind the T-Rex Dataset is to prioritize motor primitives rather than collecting large amounts of task-specific demonstrations. Instead of focusing on a small set of benchmark tasks, we organize data around 22 elementary manipulation primitives: pick, place, slide, insert, extract, wipe, fold, squeeze, peel, wrap, ... Combined with 200+ everyday objects, this produces diverse contact-rich interactions while remaining highly data-efficient.

Excited to share T-Rex: Tactile-Reactive Dexterous Manipulation 🦖🤖 Touch is fundamental to human dexterity, yet most Vision-Language-Action (VLA) models either ignore tactile feedback or lack the ability to react to high-frequency contact signals. In this work, we tackle both the data and architectural challenges of tactile-reactive dexterous manipulation. 🦖 A 100-hour tactile-synchronized dexterous manipulation dataset with 7,700+ trajectories, 22 motor primitives, and 200+ everyday objects. 🦖 A tactile-reactive MoT architecture with spatial-temporal tactile encoding and asynchronous high-frequency tactile refinement. 🦖 A scalable training recipe combining 22,889 hours of human egocentric pretraining with tactile-grounded robot mid-training. Across 12 real-world contact-rich manipulation tasks, T-Rex achieves over 30% higher average success rate than the strongest baseline. We are fully open-sourcing the dataset, models, teleoperation stack, training code, and inference pipeline. 🌐 Project: tactile-rex.github.io 📄 Paper: arxiv.org/abs/2606.17055 💻 Code: github.com/ZhuoyangLiu200… 🤗 Dataset: huggingface.co/datasets/zekai… 🧵 Thread ↓

🦖 T-Rex Dataset To enable tactile-grounded mid-training, we collect: • 100 hours of tactile-synchronized dexterous manipulation • 7,700+ trajectories • 22 motor primitives • 200+ everyday objects Instead of collecting narrow task demonstrations, we organize data around compositional motor primitives and object interactions. This provides broad coverage of contact-rich manipulation while remaining data efficient. 50 hours of the dataset is open-sourced!
