Little John is a variation of "Little N", he first appeared here: http://tw.myblog.yahoo.com/touch_classroom/ and was created by Hunter Chiou ( 邱信仁 )
Little John is a mini NXT Robot - but without any functionality. It consists of LEGO Mindstorms NXT Sensors, two wheels and a few other parts.
It looks very cute and it is easy to build. It is a nice mascot for every robot-engineer.
