Such neural systems can be embodied in machines with mechanic or any other forms of physical actuation.

The effect is reciprocal, and when a piezoelectric material is subjected to an electric field, a small change in physical dimensions takes place.

The sensors are so sensitive, and the actuation is so quick that the system may correct direction before the driver reacts.

They are pretty common. And they're a little tiny robot, a simple robot with some sensors, a little bit of processing actuation.

Researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a piezoelectric generator sufficient to operate a liquid crystal display using thin films of M13 bacteriophage.

And you're seeing a lot of things passing through its minds, a lot of self models that try to explain the relationship between actuation and sensing. It then tries to do a second action that creates the most disagreement among predictions of these alternative models, like a scientist in a lab. Then it does that and tries to explain that, and prune out its self models.
