Every machine already has a decision layer. Until now, engineers had to write it as fixed rules.

Large language models can now sit inside physical things - a grain store, a storeroom, a reception desk, a drone, a robot - understanding what cameras see and microphones hear, and answering in clean, machine-readable JSON that a £10 microcontroller can act on. The AI is available by the token from any major provider or runs on your own hardware. The electronics cost less than a good pair of boots. And very few people are doing this yet.

In The Decision Layer, chartered engineer Robin de Jongh shows you how to design, build and test these systems. Starting with a single camera watching a heap of wheat, the book builds step by step to a four-legged robot that decides for itself what to do and what to say. Along the way you will learn:

Written in a warm, personal style and illustrated in full colour throughout, with short, readable code that makes the point without turning into a tutorial, this is a book for engineers, programmers and business owners who use AI every day and want to put its judgement to work in the real world.
