CITY SHAPER Challenge Kit

The CITY SHAPER Challenge Kit is a parts set for the FIRST LEGO League robotics competition, supplying the models teams build and solve with their robot for the yearly challenge. With 2,158 pieces and 248 unique parts, it isn't a classic play set but competition material. One minifigure is included, though the mission models themselves are the real focus.

Description

A kit for competition, not for play

Unlike regular LEGO® sets, the CITY SHAPER Challenge Kit is designed for use in the FIRST LEGO League, an international robotics competition for young people. Its parts are used to build several small mission models, which get placed on a playing field and moved or triggered by a self-programmed robot. White and Light Bluish Gray dominate many of these models, giving them a clean, technical look that stands out against the colourful field markings. That sets the kit clearly apart from classic LEGO® themed sets built around a continuous story.

Models built around the year's theme

The CITY SHAPER theme centres on urban planning and infrastructure, so the mission models depict elements such as buildings, transport routes and utilities in miniature. Black adds accents to chassis parts and technical connections, while Blue highlights individual models by colour. Each model is built to require a specific interaction with the robot, such as tipping over, sliding or triggering a mechanism. This variety of small builds makes the set a toolkit for tasks rather than a single model.

248 parts across many small models

With 248 unique parts across 2,158 total pieces, the material is spread across numerous smaller assemblies rather than one large connected model. The parts list on this page shows exactly which parts are included, which is useful when pieces get lost during competition season and need replacing. For teams preparing for the FIRST LEGO League, a full parts overview is especially valuable for sourcing spares and keeping materials organised.

A kit for teams and coaches

With only one minifigure included, the kit is clearly aimed at competition teams and their coaches rather than classic open-ended play. After the competition, the models can also be reused for practice or for introducing the challenge to new team members. That gives the set practical value beyond the season itself, for schools and robotics clubs preparing several cohorts for the competition.
