Before a robot can move, sense, or think, someone has to design it! This inspiring book takes you behind the scenes to learn how engineers and inventors plan, shape, and build robots for every kind of job. You’ll discover how materials, structure, and creativity come together to turn an idea into a working machine. Find out why some robots have wheels, others have legs, and a few can even swim or fly. Learn how the shape of a robot’s body helps it move and how design makes robots strong, flexible, or super tiny!
