FIRST Robotics Competition is an international high school robotics competition organized by FIRST. Each year, teams of high school students compete to build robots weighing up to 120 pounds that can complete a task, which changes every year. Teams are given a standard set of parts and the game details at the beginning of January and are given six weeks to construct a competitive robot, that can operate autonomously as well as when guided by wireless controls, to accomplish the game's tasks. Dubbed a "varsity sport for the mind," FRC combines the excitement of sport with the rigors of science and technology.Every year, a different game is played. However, many game rules do not change from year to year and the competitive structure has not changed significantly since the competition started. Teams are randomly assigned alliances of 3 teams, which are paired into qualification matches, where they earn 'qualifying points', the calculation of which changes each year. The game changes every year, but for the most part, they involve some autonomous (computer controlled) robot operation for 10–15 seconds at the beginning of a match, followed by a much longer period (usually 2 minutes) of remote control Teams use scoring objects on the field to get points, and they sometimes get bonus points for achieving tasks such as ending with the robot on a platform, behind a certain line, or even hanging from a field structure.
