The assembly line of the Consolidated Mechanical Men Corporation specializes in half-ton worker robots, but when short on metal, the machines make something new by mistake: a boy-size robot named Sprockets. Clever, resourceful, and always ready for adventure, he is about to meet the universe—and the universe will never be the same.
In Sprockets: A Little Robot, Sprockets is adopted by Dr. Bailey and his son Jim, and embarks on a voyage into the stars. In Rivets and Sprockets, Sprockets and his little brother go on a thrilling mission to Mars. And in Bolts: A Robot Dog, the assembly line spits out another remarkable creature: the sassiest dog that Earth has ever known.
