    Variation Kills Automation: Teaching Robots Stiffness | Sze Cheong & Elijah Ong, Devol Robots

    Walk into a factory that already owns robots and you'll find the end of the line automated: packaging, palletizing. Everything in between is still done by hand - plugging connectors, assembling parts, moving a lens into a jig with 10 to 20 microns of tolerance. As Sze puts it, variation kills automation. Sze Yuan Cheong (Co-Founder & CEO, Devol Robots - a decade running manufacturing businesses before he touched a robot) and Elijah Ong (Co-Founder & CTO - turned down a Stanford PhD to help build a force-controlled arm from scratch at a three-person startup in Austin) argue that robot AI is scaling in the wrong direction. A camera can't tell a robot arm resting on a table from one pressing into it with 50 newtons. Devol teaches robots stiffness and damping, treats robot data as living in curved space instead of flat vectors, and pretrains on about 1,000 hours of data. In their own benchmark the model succeeds about 90% of the time on contact-rich tasks, where two open-source baselines land between 30 and 40%. We cover what jigs, fixtures, and integrator hours cost a factory, the keys-in-your-pocket test for what vision can't capture, an Ethernet plug insertion phase by phase, what happens when a manufacturer calls with a new task (one demonstration, then about an hour of the robot teaching itself), whether the VLA labs can scale their way to the same place, how the model runs on position-controlled robots, where it breaks, and the hard lesson from trying to build an entire hardware stack in house.

    Moving a Task From One Robot Body to Another | Aurora Feng, Neural Motion

    Aurora Feng is building a model that takes a task recorded on one robot and produces that same task on a robot it has never seen. Video and action together, with no retraining and nothing collected on the new body. Every robot foundation model lab is capped by the data it physically collected. If a robot recorded 200 tasks, a policy trained on it works in the neighborhood of those 200, and the 201st is out of distribution. Aurora's argument is that there are two ways at this problem, from the data side and from the model side, and the field has spent nearly all of its attention on the model side. Co-training on every robot dataset you can find leaves the data recipe inside a black box. Her bet is that solving it at the data stage, before anything enters the pre-training pile, is what removes the ceiling. We get into what changes and what stays invariant when the robot body changes, why kinematic retargeting solves correspondence in the wrong space, why real-to-sim-to-real loses the data on the way back, what happens to teleoperation data vendors if conversion works, and why she thinks compute is the only bottleneck left in five years. Aurora is founder and CEO of Neural Motion. She founded Saturday Robotics, the largest robotics and world model research forum in Silicon Valley, scaling it from zero to 2,600 researchers in three months and recruiting most of her team out of it. Before that she was founding head of North America at LimX Dynamics, and invested at Pear VC and ZhenFund. Stanford '24.

    Why Pixel-Based Robot AI Is an Expensive Detour | Chao Cao, Sancho

    Advanced manufacturing has automated the individual process steps. CNC, 3D printing, photolithography - however complex the step, we can build a machine for it. The handoffs between those machines still run on people, and in cell therapy that means $300,000-a-year scientists spending their days loading and unloading equipment while contamination risk and throughput bottlenecks drive up the cost of every dose. Chao Cao (Co-Founder & CEO, Sancho - CMU robotics PhD, autonomy lead for CMU's DARPA Subterranean Challenge entries, ex-Boston Dynamics AI Institute) makes the case that the dominant approach to robot intelligence, pixel-based VLA models trained on massive datasets, is an expensive detour. Sancho bets on 3D geometric world models and test-time reasoning instead, and runs the entire stack on a single onboard compute module. We cover the lasagna analogy for factory workflows, the math on the most expensive labor doing the lowest-value work, what five nines of reliability does to the data question, Waymo vs. Tesla as a data-quality argument, three years of sending robots into tunnels and caves, the October-to-March sprint from incorporation to NVIDIA's GTC keynote, the oversubscribed seed round co-led by Fusion Fund and Catapult, and why regulated cleanrooms are an easier place to start than a grocery store.

    Building the Missing Data Layer for Physical AI | James Kujareevanich, Vision Lab

    James Kujareevanich is the co-founder and CEO of Vision Lab - building the missing data layer for physical AI. They go into factories, capture first-person video of real operators performing real tasks, and turn that into structured training data for frontier labs and robotics companies. The origin story starts with an MIT PhD student who strapped a camera to his head to automate lab documentation before egocentric data was even a thing. They built a human training tool first, got pulled into the robotics data business by demand from AI labs, and just closed a $6M round to scale. We cover:00:00 - Intro00:46 - From McKinsey Bangkok to an MIT PhD with a camera on his head02:36 - The Christmas pivot: from training humans to training robots03:41 - Why robotics doesn't have its "internet" yet04:50 - What the data product actually looks like05:27 - Egocentric, tactile, teleoperation - every lab wants something different07:12 - A factory capture from start to finish07:53 - "My dad runs a factory" - the first test case08:31 - Getting factory owners to trust you09:40 - Industrial influencers and the factory network10:12 - Scaling across India, Thailand, Vietnam, Indonesia11:30 - What frontier labs learned from the pilots12:57 - The gap between what labs want and what you can deliver13:16 - Closing a $6M round and doubling the team in two weeks14:00 - New verticals beyond manufacturing14:42 - The synthetic data question15:14 - Chaos theory and why sim data compounds errors17:02 - Where defensibility lives in this business17:20 - 80% of raw footage is unusable19:29 - What the market gets wrong about robotics timelines21:28 - Hot take: convergence to 2-3 big players22:32 - The 10-year vision: becoming the Siemens of robotics23:18 - Advice for robotics founders Learn more about Vision Lab: https://thevisionlab.ai The OPTIM Update covers real-world AI, automation, robotics, industrial systems and AI Infrastructure for founders, investors, and operators.

    Building the Foundry for Physical AI | Mike Xia, Anvil Robotics

    Mike Xia is the co-founder and CEO of Anvil Robotics - building the foundry for physical AI. They make the hardware, software, and data tools that let robotics teams go from zero to model training in days vs months. They've shipped over 100 robots, manufacture in Taiwan, and just raised a $6.5M seed round. Mike gets into the economics of building and shipping a $5,000 arm, why most teams are fighting their own hardware before they can even start on AI, and what's structurally broken in the supply chain that not enough people talk about.

    Useful Now: The Case for Application-Specific Robots | Arjun Subramaniam of Factory Intelligence

    Arjun Subramaniam is the founder and CEO of Factory Intelligence - a physical AI company training tactile foundation models for industrial manipulation. He's toured 70+ factories, deployed robots on real shop floors, and is making the contrarian bet that application-specific systems beat humanoids and general-purpose foundation models right now.
