  This paper reviews the aspects of the LEGO\textregistered
Mindstorms\trademark robotics invention system 2.0 \trademark (RIS), by
presenting the different elements of the kit, and relating them to actual robot
components and norms. Furthermore a comparison between the LCS and Java is
made, as well as comparing the RCX board to other technologies, specifically
LEGO \textregistered NXT and MIT's "Handy Board". Also, concrete examples of
application using the RIS are presented.
