FIRST LEGO League (FLL) is an international program for kids ages 9-14 that combines a hands-on, interactive robotics program and research presentation with a sports-like atmosphere. FIRST LEGO League: The Unofficial Guide is the go-to source for coaches, teachers, parents, and students participating in the FLL competition. Written for both rookie and experienced teams, the book covers a variety of topics, including team formation and organization, robot building and programming, and more. FIRST LEGO League goes into great detail about the structure of the FLL competition, focusing on the four key judging areas: Robot Game, Technical, Project, and Teamwork. Filled with practical advice and real building and programming examples, as well as candid commentary from veteran teams, this is the book that your team needs whether you're just starting out or have been competing (and winning) for years.
