Read the funny story of two inquisitive kids, Ty and Karlie, and build simple, non-motorized models of the robots they construct and fix during their adventure to an automated candy factory! During this zany outing, Ty and Karlie build various robots to perform tasks and solve problems in the factory. The 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.
