A thick, glossy robot reference you flip through rather than read front to back, heavy on cutaway diagrams and how the machines actually work inside.
It's a fact book, not a story. Big glossy spreads mix photographs with cutaway diagrams: how a robot senses the world and moves, what's packed inside one, the history from clockwork automata up through industrial arms, bomb-disposal robots, drones, Mars rovers, surgical robots, and the walking humanoids that counted as cutting-edge when it came out. The text comes in short blocks under headings, so a child can open to whatever page catches their eye and stay there.
This is the robot book for the child who has stopped wanting robots that talk and feel and started wanting to know how the arm actually moves. It's a real reference at 64 pages, pitched at an independent reader somewhere around 7 to 11, and it treats the subject seriously: what a sensor is, what an actuator does, why balancing on two legs is so hard for a machine. The photographs and diagrams carry a reader who can't yet sit with a wall of prose. The reason to own it is that depth on the mechanics, and that part doesn't date.
