Shippu and Inazuma Eleven are both sports anime that are clearly aimed at the kiddies. While it's true that Shippu is inhabited by mostly robots and Inazuma's cast is of the human variety, each has a very childish feel and will be aimed at the same audience.

Welcome to the game of Live On! In it, people known as Cardlivers use collectible cards to summon mysterious creatures for battles. One such Cardliver is Kakeru, an elementary school student who wants nothing more than to beat his friend Ai in a game. During a stroll through a park Kakeru runs across a hurt puppy named Petal and, using a card that it gives to him, transforms into a wondrous wolf and defeats the dog's would-be and sinister captors. Alongside Petal, Kakeru sets forth with his new cards to become the best Live On player around!
Admittedly, Live On Cardliver is a card battle anime while Inazuma Eleven is solely sports, but they both have a very, very similar feel and I'm almost certain they'll be enjoyed by the same audience. Each is stereotypical shounen fare with an overly eager protagonist and plenty of glorified battles (whether on the field or with monsters). Try it on for size.
