Description

Accessories for robot builders

Mindstorms RCX was the programmable robotics system from LEGO®, in which a control brick drove motors and sensors. This set does not deliver a robot but accessories with which such models can be extended. The 45 pieces in black, yellow, light grey and trans-dark blue cover 18 different types, a varied mix of connecting and construction parts. The transparent share stands out, since dark blue see-through parts can serve as covers for light sensors or as windows on robot models and vehicles.

Who the set suits

It is interesting for builders who want to add extra parts to existing Mindstorms models or combine their own constructions with other bricks. Collectors of the range will also find an addition from the year 2000 here. Without the RCX brick itself, the set alone is not yet a working robot. The parts list further down lists every part included.
