Description

Made for classrooms and competitions

This set comes from the Educational and Dacta range and is aimed at schools, clubs and teams rather than the typical playroom. The name suggests shared tasks: groups build robots, program them and tackle set challenges. ROBOLAB is the programming software, and the USB version refers to the computer connection. With 833 pieces, the supply is enough for several small robots or one larger model, so groups can divide the work comfortably between them.

Plenty of engineering, little decoration

With 150 different parts, the variety is strikingly high for a set of this size. That suits a technical kit, where axles, gears, connectors and beams matter more than decoration. Black, light grey, yellow and blue are the most frequent colours, which looks like classic functional colouring: grey and black parts for the structure, with yellow and blue used for accents and for making components easier to recognise. That helps when sorting parts in a classroom, because the groups can be told apart by colour.

Build, test, improve

The appeal of sets like this lies in the process: build, test, discover something does not work, and improve it. Working in a team means sharing tasks, comparing solutions and learning how mechanics and control fit together. The many part types are a strength here, because gearboxes, chassis and grabbers can each be solved in several ways. As a pure display piece the set is less convincing; it is meant to be used and rebuilt. The shared hunt for a fault often stays in the memory longer than the finished model.

Parts list and reuse

This page has the complete parts list covering all 150 part types. That is especially useful when you buy a used copy, since so many small technical elements can easily go missing. The “What can I build?” tool also checks which other sets you could build from these bricks, fully or partly, so the contents remain worthwhile even if you lack the matching software. After all, the pieces remain ordinary bricks that work perfectly well for free-form models.
