FIRST Lego League


In 1998, the FIRST Lego League (FLL), a program similar to the FIRST Robotics Competition, was formed. It is aimed at 9 to 16-year-old students and utilizes Lego Mindstorms sets (NXT or RCX) to build palm-sized Lego robots, which are then programmed using the ROBOLAB software to autonomously compete against other teams[9]. The ROBOLAB software is based on National Instruments' LabView industrial control engineering software. The combination of interchangeable Lego parts, computer 'bricks', sensors, and the aforementioned software, provide preteens and teenagers with the capability to build reasonably complex models of real-life robotic systems.[citation needed] This competition also utilizes a research element that is themed with each year's game, and deals with a real-world situation for students to learn about through the season.The FIRST Tech Challenge (FTC), formerly FIRST Vex Challenge (FVC), is a mid-level robotics competition announced by FIRST on March 22, 2005. According to FIRST, this competition was designed to be a more accessible and affordable option for schools. FIRST has also said that the FTC program was created for those of an intermediate skill level. FIRST Tech Challenge robots are approximately one-third the scale of their FRC counterparts. The FTC competition is meant to provide a transition for students from the FLL competition to the FRC competition. FTC was developed for the Vex Robotics Design System, which is available commercially.

The 2005 FVC pilot season featured a demonstration of the FIRST Vex Challenge using a 1/3 linear scale mock-up of the 2004 FRC Competition, FIRST Frenzy: Raising the Bar. For their 2005-2006 Pilot Season, FVC teams played the Half-Pipe Hustle game using racquet balls and ramps.

For the 2006-2007 FTC Season, the FIRST Tech Challenge teams competed in the Hangin'-A-Round challenge using softballs, rotating platforms, a hanging bar, and a larger 'Atlas' ball which is significantly larger than most Vex robots and harder to manipulate. Competitions were held around the United States, Canada, and Mexico.
