This, ladies and gentlemen, is the world's first stainless steel robot with seven degrees of freedom. But before I explain what that means or why it matters, kindly take a moment to watch this Kawasaki Heavy Industries bot dance. Nice moves!

Impressed? Ok, now let me explain. In mechanics, "degrees of freedom" are the number of different independent parameters that can define its motion. So basically this robot is flexible like a yoga instructor, and because it's made of stainless steel it can be used in clean room situations for the pharmaceutical industry. Kawasaki Heavy Industries plans to start selling the bot next year, but that doesn't mean we can't enjoy its moves now. [DigInfo]
