Description

A set built for competition

Unlike most LEGO sets, this model isn't primarily intended for building at home; instead it provides the official field and models for an educational robotics competition. Teams typically use sets like this to build several small missions and tasks, which then need to be solved using a robot they've programmed themselves. The UNEARTHED theme points to an archaeological or earth-science subject for that season, likely reflected in the individual building elements and missions. For schools, clubs and interested families, this set is less a collectible and more a learning tool for engineering and programming.

Functional competition colours

Light bluish grey and dark bluish grey form the backbone of many components, while black covers technical elements and red provides bold markings and warning details. With 480 distinct parts, the set offers enough variety to build several different mission models at once, which is typical of competition fields. That fairly plain, functional colour choice stands out clearly against the colourful palettes of typical play sets and underlines the set's technical, serious character. The restrained colours also help robots and sensors stand out clearly against their surroundings.

One figure as a minor detail

Unlike many other sets, the focus here is clearly on mechanics and function, which is why only a single minifigure is included rather than a larger cast. That figure serves more as a scale reference or small detail within the missions than as a central play element. For teams preparing for the actual competition, building and programming the robot takes priority over classic figure-based role play anyway. That sets this set clearly apart from most other LEGO sets, which lean much more heavily on play scenes.

Parts list for teams

The full parts list on this page shows which specialist pieces were used for the individual mission models, useful for teams reordering specific parts or preparing the set in detail. It also makes organisation easier when several teams work with the same set at once and need to split parts between them. That makes it possible to check well ahead of competition day that every mission model can be fully assembled.
