FIRST Lego League (FLL) Challenge

Littleton Robotics launched the middle school program, FIRST Lego League, in June 2017 for students in 4th-8th grade. In this program, students are tasked with building a fully autonomous robot to complete specific game missions, completing an in-depth research project on a topic related to the game theme, and demonstrating their teamwork abilities. Our teams participate in a short summer program (July and August) and then the competition season runs August-December. Participation in the summer program is not required for the fall program

Our fall FLL competition team programs meet Tuesdays and Thursdays 6-8pm at our workspace in Littleton, MA starting on August 18, 2022. In addition, there will be a few meetings on weekends to prepare for and attend events and competitions in November/December. Students must be entering 4th grade (or older) in the fall of 2022 to participate.

$200 (scholarships available)

FIRST Lego League Discover and Explore

FLL Discover (ages 4-6, 2-4 students per team) and FLL Explore (ages 6-10, 2-6 students per team) are the FIRST programs for younger students. Teams participate in once a week meetings for 10-12 weeks, which can start at any point in the year, and work together design a LEGO creation that addresses specific problems. At the end, teams can create a poster to showcase what they have learned and attend an Expo event to share their LEGO creation with the community.

Littleton Robotics does not run FLL Discover or FLL Explore programs, but would be happy to answer questions for parents who want to establish their own. The program cost is low, especially when split among a few families, and comes with a structured week-by-week 10 session curriculum to follow. No previous experience is required of the adult coaches.

Cargo Connect FLL Challenge Season 2021

We were excited to bring FLL back to our Littleton workspace in the fall of 2021 with two teams and participate in in-person competitions. The teams got a late start at the end of September and all but one of our students was new to FLL, but the teams worked hard to learn a lot in a very short period of time! We’re really proud of how they dug in and got to work, guided by some of our FRC students and our new Head Coach Megan. Our Littleton Levers FLL team won an Innovation Award at their competition and our Mechanism Madness FLL team qualified for the FLL Massachusetts West State Championship. Congratulations to everyone!

RePLAY FLL Challenge Season 2020

The coronavirus pandemic upended the 2020-2021 FLL season in a major way! Between Littleton and Bolton, we were fortunate to still be able to run 4 FLL teams that met through the fall and winter in cold open garages and via online meetings. The Bolton teams even held an outdoor mini-scrimmage in early April that included snow and 25mph winds! But all teams were able to submit videos of their robot missions and participate in online interviews to complete their season. Congratulations on all your hard work!

City Shaper FLL Season 2019

All 5 of our FLL teams had a BLAST competing in this year’s game, City Shaper. Our teams were tasked with coding an autonomous EV3 robot to complete missions in the robot game. As well, our teams identified and attempted to solve a real-world problem. Our teams competed in three practice events before competing at their qualifier at Assabet Valley High School. Our teams did great at this event, bringing home the Innovation Project Solution Award and Inspiration Award. As well, two (Wild Wedges and Mechanism Madness) qualified for the Massachusetts State West Championship, Robonautica, at WPI.
