The bottleneck choking physical AI development isn't processing power anymore—it's training data. Encord, a data annotation startup, is now experimenting with brain wave sensors and electrical muscle signals to generate the densely labeled manipulation data that humanoid robots desperately need to learn real-world tasks. Working with German robotics startup Zander Labs, the company estimates that richly annotated physical training data is worth 100 times more than basic video footage, yet costs 20 times more to produce. That gap has created a new industry. As robotics companies race to scale humanoid platforms—Boston Dynamics, Tesla, Figure AI all pushing harder—the constraint isn't their models' capacity to learn; it's the sheer scarcity of high-quality behavioral data. Encord's bet is that biometric signals—the electrical noise your brain and muscles produce during movement—can be captured and translated into precise annotations of intent and action that video alone cannot capture. If they're right, brain waves become a tool for manufacturing training data at scale, unlocking the next generation of physical AI the same way internet data unlocked the last generation of language models.
