Since kits became available last year, there certainly hasn't been a shortage of clever robots over at the Lego Mindstorms NXT community, but Roy Watanabe's NXTway-G caught our collective eye. He took direct inspiration from similar self-balancing bots, the Legway and NXTway (basically NXT brick-controlled mini-Segways), but took it to the next level by using a gyroscopic sensor -- and from the looks of the video, it's a smooth operator. NXTway-G can stand in place, climb a slope, and take a modest shove. We say modest because of its one downfall -- if knocked flat, it'll find itself in one of those "I've fallen and I can't get up" situations -- and nobody wants a whiny bot on their hands.
