Where it came from
The HYDRO DYNAMICS Challenge Kit, released as part of the 2017-2018 FIRST LEGO League season, was designed as an educational tool to accompany the competition's theme of water management. The set provided teams with a variety of specialized plastic components and minifigures to build the mission models required for the season's robot game, reflecting the initiative's goal of teaching students about the human water cycle through hands-on engineering challenges.
The kit features a vibrant aesthetic centered on a deep blue and white color palette to evoke water and infrastructure themes. Like other FIRST LEGO League challenge sets, it was developed by LEGO Education in collaboration with FIRST to ensure durability and ease of assembly for competitive robotics teams. While the set was not intended for retail sale to the general public, it became a central, albeit temporary, fixture in thousands of schools and clubs globally during the competition year.
