What makes a robot zoom, spin, or even dance across the floor? Inside this book, you’ll find out how motors and actuators power every robot’s movement. Learn how electricity becomes motion, how gears turn force into strength, and how balance helps robots stay upright on two legs or four wheels. Meet rolling robots, walking robots, swimming robots, and flying robots! Explore how engineers study animals to design new ways for robots to run, jump, and glide. From factory arms to friendly robot pets, you’ll see how motion makes machines come alive.
