If it takes you more than five minutes just to figure out what it is, you’re probably too old to play with it. Such is the case with the LEGO Mindstorms 2.0. The genius lies in the computer-controlled LEGO brick that lets the Mindstorms robot come alive and perform different operations. Users choose from several robot models and program them using intuitive programming software. With the help of fancy sensors and speakers, robots can walk, talk, hear and even feel. How? Hmm…you’ll have to ask a kid.
