Architecture

Vision-Language-Action ModelTake a model that already understands images and instructions, and give it a third output: what to do with a body.verified

Data

Teleoperation DataRobot training data is collected by people driving robots, one episode at a time, in real time.verified

Foundations

Contact DynamicsEverything a robot does that matters involves touching something, and touching is where the physics stops being…verified
ManipulationPicking things up is the problem that has stayed hard.verified
ProprioceptionA robot knows where its own joints are, precisely and at high frequency, without looking.verified

Methods

Action ChunkingInstead of deciding one action at a time, predict the next half-second of motion at once and execute it.verified

Regimes

Embodiment GapA policy trained on one robot rarely works on another.verified

Safety

Safety EnvelopeA learned policy on real hardware can hurt somebody, so it does not get the final say.verified
