NgeokNean made this very cool LEGO Mindstorms NXT walker – I’ve never seen this kind of pivot-mechanism used for turning, it’s very creative!

    Someone should let the guys at “Prototype This!” know about it. Their walker, designed to carry a person, failed because it didn’t have the HP to maintain sync on the “legs”. Maybe they could use this system to get it working.
