LEGO MINDSTORMS Robot Commander by The LEGO Group requires the LEGO MINDSTORMS EV3 box in order to play, but wow! Kids can build and create their own robots, then command movements with this app. Think of the science! Think of the robots! Think of getting little Jane to create a robot that brings you a glass of water! Maybe not, but it's still a super-cool toy and app. A mom can dream about robots made by her kids to help around the house, right?
