FIRST is the world’s leading youth robotics community, delivering hands-on STEM learning that inspires innovation, builds confidence, and prepares kids for life. Across the globe, students thrive in our programs — powered by mentorship, teamwork, creativity, and engineering challenges.

This year, the FIRST Lego League Challenge theme is UNEARTHED. This post-season competition will build on that robotics game challenge and infuse Wisconsin-centric chaos for a truly memorable event. In addition, teams will compete for the FIRST WI FLL Ambassador award – showcasing a team who truly embodies the core values of FIRST robotics.

We are excited to have 13 teams join us for this udderly chaotic special event!
