This robot has two eyes, two arms, and two legs, but what really makes him tick? Inside The Robot Book, Heather Brown answers that question within an interactive story that features actual working--and moving--parts. Gears and cogs are mounted on each illustration to keep little fingers and imaginations engaged.

Die-cut thick-paper nuts, bolts, and gears are fastened to the pages with metal grommets to move, turn, and spin.
