NXT One-Kit Creatures offers full-color building and programming instructions for five original animal robot designs that can be built with a single LEGO MINDSTORMS NXT 1.0 or NXT 2.0 kit. The animals are an undulating shark, a crawling horseshoe crab, a backwardly-mobile dung beetle, a walking chick, and a leaping grasshopper. Each design shows another unique way to make an animal robot move. Anyone new to the NXT will find these models easy to build and operate.
