FLL

First Lego League is a branch of FIRST that allows kids from 4th to 8th grade to being their engineering experience though the use of LEGOs. Teams consisting of up to 10 students and at least 1 mentor go against each other with their creations. These “creations” are autonomous robots created using LEGO Mindstorms. FLL has competitions yearly and are hosted by their partners in areas close to the different teams.
