FIRST Lego League (FLL) Challenge

Littleton Robotics launched the middle school program, FIRST Lego League, in June 2017 for students ages 9-14 (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 team work abilities. Our teams participate in a summer program (June-August) and the competition season runs August-December. 

Our Fall 2021 FLL program started in September and we are no longer able to accept new students. We’ll post information about a possible summer program and the Fall 2022 program in the late spring of 2022. In the meantime, learn more about the 2021 Cargo Connect FLL season!

FIRST Lego League Explore

FLL Explore is the FIRST program for 6-10 year olds. In this program, teams of up to 6 students participate in once a week meetings for 10-12 weeks, designing a programmable LEGO creation to solve specific problems. For example, in the most recent game, Boomtown Build, students were tasked with designing a LEGO Building that would solve a problem and make life more simple for the people who use the public space! At the end of the season, teams create a poster to showcase what they have learned, and attend an Expo event to share their LEGO creation with the community.

RePLAY FLL Season 2020-2021

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 2019-2020

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.

FLL Deep Space Summer 2019

Littleton Robotics designed FLL Deep Space to provide an engaging summer program for FLL students that will help prepare them for the upcoming FLL competition season (CITY SHAPER). It is a part of our FLL to FRC Transition Program, encouraging current FLL students to make the jump to FRC upon graduation from FLL.

The game is intended to be simple enough that robots can be built and programmed to play it in a 1 week-long session, or with once a week meetings for the duration of the summer.
