he robots have moving parts, wheels, and gears, so kids can learn firsthand about simple machines and gear trains. As you follow the story, you can build models of the ten robots featured in the story. Large, colorful plastic building pieces make it easy for small hands to put the models together. In the story, the kids build robots with arms that rotate, turn, and spin. They fix a robotic arm and other specialized robots that complete specific tasks inside the factory. They construct a robotic drone that flies through the factory to coat the candies in sprinkles, wheeled robots that zoom across the factory floor, a taffy-pulling robot, and a funny gum-kneading robot.
