Listen, it's been a long week. Sometime you just want to build Lego robots for a bit. This week, Lego unveiled its second generation WeDo education kit, which includes all the pieces, motors, and sensors necessary for elementary-level students to build robots (and, subversively, learn about science and engineering along the way) — robots that are programmed using an intuitive drag-and-drop programming system for computers and tablets. Lego Education's Pamela Scifers stopped our CES lounge to give us a demo and let us play with toys. Enjoy.
