The Physical AI stack has three layers.
Hardware: sensors that bring the physical world in, actuators that execute decisions in it, edge compute that handles inference at robot-control speeds.
Models: the foundation VLA that takes visual observations and language instructions and outputs motor commands, simulation for pre-deployment training, inference runtime that bridges a 7B-parameter model and hardware that needs to respond in milliseconds.
These two layers are increasingly understood. The open-source models are available.
The data layer sits between them.
Robotics engineers own the hardware. ML engineers own the models.
The data layer belongs to both and gets designed by neither.
It appears instead as a mid-project problem: the annotation schema doesn't capture what the model actually learns from, the temporal synchronization wasn't built into the hardware integration, the collection infrastructure wasn't designed before sensor selection was finalized.
Each of these is expensive to correct retroactively.
What the data layer contains: demonstration collection infrastructure, annotation pipelines requiring domain expertise, temporal synchronization across multimodal streams, dataset management treating the corpus as a living system, and continuous fine-tuning loops that close the gap between deployment failures and the next training cycle.
The teams that run into trouble scoped the model layer first and assumed data collection could be worked out afterward.
The layer that belongs to everyone's problem ends up in nobody's architecture.
