    Why Data Is the Real Secret to Scaling Physical AI | Varun Nair

    In this conversation, we sit down with Varun Nair to dig into the high-stakes world of data for robotics and physical AI. We talk about what actually matters for training robot intelligence. From egocentric video to UMI over teleop, simulation and the gaps between them. You will also learn why the field is still figuring out which data scales and the limits of human-operated data, evaluation challenges, and what it will take to move from demos to real deployment. If you’re building, investing in, or just obsessed with robotics and embodied AI, this one’s for you. #robot #data #ai 0:00 Podcast Overview 0:30 Data Market 1:30 Varun's Background 3:01 Robotics & Crypto 6:27 Physical AI Definition 8:32 Simulation for Deployments 10:45 World Models 11:45 What is good data ? 12:42 GPT 6 Astra Evaluation 13:50 Data Life Cycle 17:01 Modalities & Pseudo Labeling 19:40 Depth for LLMs 20:19 How labs use data 21:38 Deployment Data = Post Training Data 22:17 Teleoperation 24:00 Patient Capital vs Impatient Capital 24:47 Benchmarks 26:35 UMI Data for Mid Training 27:35 Has Openai been training on robot data? 30:59 Humanoid vs other Embodiments 31:36 Hard vs Easy Tasks for Robots 32:51 Simulation 33:59 Niantic Spatial 34:42 Is robotics data broken? 36:17 Model Companies 37:38 Robot Everest 38:11 Avea 38:47 What Varun looks for 40:17 Outro Guest https://x.com/_varunnair Léo https://x.com/LeoKharon Oskar https://x.com/hundreddaysx Podcast https://x.com/roboticsstack

    ChatGPT-6 Astra for Robotics | Demos, Benchmarks & Future Applications

    GPT 6 Astra is OpenAI's most powerful model. So can it be used for robotics? In this episode we look at various demos that show people implementing GPT 6 Astra to control robotic arms and more. Some work in simulation, some work in real environments. And the results are actually surprising. The LLM even starts showing up on various benchmarks and sometimes outperforms SOTA Physical AI models. Of course, there are caveats to this but the performance is seriously impressive. #chatgpt #astra #gpt #podcast 0:00 Podcast Overview 0:32 GPT 6 Astra 3:35 Demo 1 - Painting Robot Arm 5:43 Demo 2 - In Context Learning 8:30 Demo 3 - Robocurve Office Tasks 11:29 Demo 4 - Hand Simulation 15:16 Demo 5 - Drone Flying 17:38 How to use Astra with Robots 18:07 Policy-like 18:51 Agent 19:32 Teacher-like 19:58 Is Astra a VLA ? 21:20 Was it trained on Robot Data? 22:38 Task Annotation Experiment 24:09 Demo 6 - Safety Testing 26:44 Limitations 29:40 Comparison & Outlook 33:52 Outro Léo https://x.com/LeoKharon Oskar https://x.com/hundreddaysx Podcast https://x.com/roboticsstack

    Is This Tactile Glove the Missing Piece for Humanoid Robots? | Matt Wulff (6thSense)

    In this episode of the robotics stack podcast, we explore tactile data capture hardware with Matt Wulff from 6thSense. He is one of the co-founders and joins us to discuss the specialized robotics hardware required to give robots a realistic sense of touch. We examine how current systems struggle with physical dexterity and why new hardware approaches are essential for advancement. We break down the entire data capture pipeline from deployments to engineering the gloves & camera involved and how to turn this into useful robotics training data. We also speak about what the future holds for hands, humanoids & more! #robot #data #podcast 0:00 Podcast Overview 0:39 The Future of Robotics & 6thSense 1:44 Background 2:20 Egocentric Video & Tactile Data 3:15 Stereo vs. Monocular Video 4:43 6thSense Products & Services 5:28 Hardware 5:33 Cameras 6:06 Gloves 6:50 Product Development 8:18 Team 9:19 Funding 9:50 Deployments I 10:14 Data Capture Methods 11:06 Deployments II 12:38 Competitive Edge 16:50 Tactile Sensors 19:26 UMI Data 21:40 Data Management & Processing 23:10 Data Quality 24:25 Strategy & Partnerships 26:38 More Cameras 28:20 Hand to Gripper Data 29:07 UMI / Teleoperation 31:54 Robot Model Training 33:45 Capture Rig Implementation 35:28 Robotic Hands 36:30 Who will win Humanoids? 38:19 GPT Astra 40:00 Future 41:35 AI 42:55 Stock Picks 45:32 Robot Skin 47:30 Is Video Enough? 49:14 Outro Guest: https://x.com/makeitmatto Léo https://x.com/LeoKharon Oskar https://x.com/hundreddaysx Podcast https://x.com/roboticsstack
