Robotics Model Training Using Community Data

🚀𝐖𝐞 𝐚𝐫𝐞 𝐢𝐧𝐭𝐫𝐨𝐝𝐮𝐜𝐢𝐧𝐠 𝐒𝐦𝐨𝐥𝐕𝐋𝐀-𝟒𝟓𝟎𝐌, 𝐚𝐧 𝐨𝐩𝐞𝐧-𝐬𝐨𝐮𝐫𝐜𝐞 𝐕𝐢𝐬𝐢𝐨𝐧-𝐋𝐚𝐧𝐠𝐮𝐚𝐠𝐞-𝐀𝐜𝐭𝐢𝐨𝐧 𝐦𝐨𝐝𝐞𝐥 𝐟𝐨𝐫 𝐫𝐨𝐛𝐨𝐭𝐢𝐜𝐬! SmolVLA achieves best-in-class performance and inference speed, and the best part? It’s trained entirely on open-source datasets from the 🤖 LeRobot project hosted on the Hugging Face Hub. 🔍 Why is SmolVLA so good? Turns out that pretraining on a large, diverse and noisy collection of real-world community robotics data leads to better generalization and control. We saw a 26% boost in task success rate simply from adding community dataset pretraining! ⚡ Why is SmolVLA so fast? 1. We halved the size of SmolVLM and extract intermediate representations 2. Introduced interleaved cross- and self-attention layers in the action expert 3. Enabled asynchronous inference so the robot acts and reacts simultaneously 💡 Unlike most academic datasets, these community-contributed datasets are naturally diverse: ✅ Multiple robots, camera angles, and manipulation tasks ✅ Real-world messiness and complexity ✅ Crowd-sourced and community-cleaned using Qwen2.5-VL for high-quality task descriptions 🌍 SmolVLA is a step toward making robotics research more affordable, reproducible, and collaborative. 📖 Want to dive deeper?

90% success rate in unseen environments. No new data, no fine-tuning. Autonomously. Most robots need retraining to work in new places. What if they didn’t? Robot Utility Models (RUMs) learn once and work anywhere... zero-shot. A team from NYU and Hello Robot built a set of general-purpose robot policies that can open drawers, pick up bags, and more, without needing extra training for each new home, setup, or lighting condition. Why RUMs matter ✅ Trained once and deployed in 25+ new environments without fine-tuning ✅ Uses a cheap handheld iPhone-based tool for fast, high-quality data collection ✅ Boosts performance with mLLM-based self-check and retry system ✅ Achieves 90 percent average success rate in real-world zero-shot tasks RUMs show that smart data collection and multi-modal learning can unlock truly general robotics.

Robotics data is expensive and slow to collect. A lot of videos are available online, but not readily usable by robotics because of lack of action labels. AMPLIFY solves this problem by learning Actionless Motion Priors that unlock better sample efficiency, generalization, and scaling for robot learning. Our key insight is to factor the problem into two stages: The "what": Predict the visual dynamics required to accomplish a task The "how": Map predicted motions to low-level actions This decoupling enables remarkable generalizability: our policy can perform tasks where we have NO action data, only videos. We outperform SOTA BC baselines on this by 27x 🤯 AMPLIFY is composed of three stages: 1. Motion Tokenization: We track dense keypoint grids through videos and compress their trajectories into discrete motion tokens. 2. Forward Dynamics: Given an image and task description (e.g., "open the box"), we autoregressively predict a sequence of motion tokens representing how keypoints should move over the next second or so. This model can train on ANY text-labeled video data - robot demonstrations, human videos, YouTube videos. 3. Inverse Dynamics: We decode predicted motion tokens into robot actions. This module learns the robot-specific mapping from desired motions to actions. This part can train on ANY robot interaction data - not just expert demonstrations (think off-task data, play data, or even random actions). So, does it actually work? Few-shot learning: Given just 2 action-annotated demos per task, AMPLIFY nearly doubles SOTA few-shot performance on LIBERO. This is possible because our Actionless Motion Priors provide a strong inductive bias that dramatically reduces the amount of robot data needed to train a policy. Cross-embodiment learning: We train the forward dynamics model on both human and robot videos, but the inverse model sees only robot actions. Result: 1.4× average improvement on real-world tasks. Our system successfully transfers motion information from human demonstrations to robot execution. And now my favorite result: AMPLIFY enables zero-shot task generalization. We train on LIBERO-90 tasks and evaluate on tasks where we’ve seen no actions, only pixels. While our best baseline achieves ~2% success, AMPLIFY reaches a 60% average success rate, outperforming SOTA behavior cloning baselines by 27x. This is a new way to train VLAs for robotics which dont always start with large scale teleoperation. Instead of collecting millions of robot demonstrations, we just need to teach robots how to read the language of motion. Then, every video becomes training data. led by Jeremy Collins & Loránd Cheng in collaboration with Kunal Aneja, Albert Wilcox, Benjamin Joffe at College of Computing at Georgia Tech Check out our paper and project page for more details: 📄 Paper: https://lnkd.in/eZif-mB7 🌐 Website: https://lnkd.in/ezXhzWGQ
