Optional Pathway - NXT Not the first of its kind

I had never heard of Mindstorms or robotic Lego before this project. It appears this has been a work in progress from Lego since 1985. (Although motorised Lego first came about in the late 1970's) The first of the three (the Cybermaster) ran on radio waves picked up by the massive antenna on it's back. Then came the RCX, the closest relation to the NXT, there is clear comparison in the way these two work compared with the original. Below is a picture of all the parts that build up the RCX Mindstorm robot and below this is an enlarged image of RCX computer note the similarities in comparison to the new NXT kit.
