Layer 1: Training and Model Development

Before any Physical AI system can work in the real world, it needs to learn.
That sounds obvious, but I think it is a really important place to start because is is very easy to jump right to the machine itself. Whether it is a robot, a drone, an autonomous vehicle. The humanoid. Whatever visual example is easiest to picture and what people think about when they hear 'Physical AI'.
But before any of that becomes useful, there has to be a learning process behind it.
A physical system needs to understand:
> what it is seeing
> what it is trying to do
> what a good outcome looks like
> what a mistake looks like
> what action should come next.
That can come from:
> real-world data
> synthetic data
> video
> simulation
> human demonstrations
> expert feedback
etc.
There are so many exciting companies in this layer and it is often overlooked when we think about Physical AI thematic
