2021 - Infinite Recharge

Infinite Recharge was the FRC game for the 2020-2021 season, in partnership with Lucasfilm as part of its Star Wars: Force for Change initiative. The Infinite Recharge game involved two alliances of three teams each, with each team controlling a robot and performing specific tasks on a field to score points. The game centered around a futuristic city theme involving two alliances consisting of three teams each competing to perform various tasks, including shooting foam balls known as Power Cells into high and low goals to activate a Shield Generator, manipulating a Control Panel to activate this shield, and returning to the Shield Generator to park or climb at the end of the match. The objective was to energize and activate the shield before the match ends and asteroids strike FIRST City, a futuristic city modeled after Star Wars.
