Description

Programming with bricks

ROBOLAB is the programming environment schools used to control the RCX bricks. This set belongs to that system and provides the material for building and programming amusement park rides. Learners construct attractions that move, react and solve tasks. The appeal lies in the interplay of mechanics and logic: whatever you build, you also have to control. The set supplies the parts, while the programmable brick and the software come from the range's core equipment rather than from this box.

Five figures for the park

With five minifigures the rides get visitors who can spin and ride along. That turns a technical experiment into a small story and makes results easier to present. Light grey and black dominate the colours, joined by blue and red. This mix is typical of educational sets: neutral technical parts as a base, bright elements for orientation. With 76 different part types among 270 pieces the stock is nicely varied without being overloaded, so a class can share it out sensibly.

A piece of educational history

Today it is mainly collectors who care about these sets. The RCX generation was the forerunner of the later Mindstorms lines, and many of its parts still turn up in custom builds. The parts list on this page shows exactly which elements are included. With second-hand copies, check in particular that all the gears, axles and small connectors are there, because those go missing easily and are hard to replace one by one.

Building on from your stock

If you own the set, add it to your collection in the What can I build? tool to find out which other models it allows. The mix of gears, axles and frame pieces suits moving constructions such as carousels, lifts or small robots. Even without a control brick, many mechanisms can be driven by hand and tested, which fits the spirit of the set and still teaches you plenty about gearing, which suits curious builders of any age.
