Description

Learning through fairground rides

This set comes from the education side of the catalogue and was not designed as a toy for the bedroom floor. It targets schools and study groups that work with Mindstorms RCX and use the ROBOLAB software alongside it. An amusement park offers vivid tasks for that: carousels spin, rides move, and everything can be controlled through programming. At 306 pieces the set is compact enough for a group to reach results within a single lesson or workshop session.

Five figures, four main colours

The five minifigures give the models visitors who ride along or watch, which brings the results to life. In terms of colour, light bluish grey, black, blue and red dominate. These are clear, technical-looking tones that go well with gears, axles and frames. The 87 different part types are split between structural and connecting elements. The parts list on this page shows exactly which elements are included, which helps when comparing against your own Technic stock.

Display, demonstrate, rebuild

Anyone who owns this set today usually has either a collector's item or an add-on for robotics projects. The building follows the idea of understanding mechanical principles: gearing, rotation and control. If you want to design fairground rides of your own, the parts give you a solid base that can be expanded with other Technic sets. Without the matching programmable brick the models stay static, although they still demonstrate nicely and can be turned by hand.

Reusing the parts

With “What can I build?” you can see which other sets you could assemble from your stock plus this one. The parts list also supports you when looking for gears, axles or connectors. With older educational sets it is worth looking at the individual pieces, because many suit Technic models and your own mechanical experiments, even if the original purpose, programming with the RCX, no longer plays a role in your collection. The minifigures can also be used in other scenes.
