Seasonal kits for FIRST LEGO League robotics

FIRST LEGO League is an educational robotics program in which teams take on a challenge built around a theme each season. The sets in the theme follow this rhythm and carry the name of the year's theme: 9782 VOLCANIC PANIC Challenge Kit in 2000, 9788 MISSION MARS Challenge Kit in 2003, 45801 TRASH TREK Challenge Kit in 2015 or 45832 BIOGLOW Challenge set in 2026.

The theme totals 54 sets. From 2003 to 2012, only one set is released each year. Releases then multiply, with 4 sets in 2013, 6 in 2021, then 3 per year from 2022 to 2026.
