Infinite Recharge. Infinite Recharge (stylized in all caps) is the FIRST Robotics Competition (FRC) game for the 2020 season. The season is in partnership with Lucasfilm as part of its Star Wars: Force for Change initiative.

The Infinite Recharge game involves two alliances of three teams each, with each team controlling a robot and performing specific tasks on a field to score points. The game centers 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 is to energize and activate the shield before the match ends and asteroids strike FIRST City, a futuristic city modeled after Star Wars.

The 2020 season was the first season without an enforced six-week build period, with teams able to work on their robot at any time after kickoff. However, teams are in general not permitted to work on their robot outside of pit hours during an event the team in question is competing at.

The 2020 season was suspended on March 12, 2020, and all remaining events were cancelled on May 13, due to the COVID-19 pandemic. On the same day, it was announced that Infinite Recharge would also be played in 2021, with possible "changes" to be revealed at that season's kickoff.

Kickoff 
The season's kickoff event took place on January 4, 2020, at 10:00 AM Eastern Time and was centered around an impending asteroid impact threatening the FIRST City. The event was broadcast from Manchester, New Hampshire over Twitch.

Field 

Infinite Recharge is played on a 26 ft 11 1/4 in (~821 cm) by 52 ft 5 1/4 in(~1598 cm) field covered in grey low-pile carpet. The field is bounded by short transparent polycarbonate guardrails on the longer sides and the taller Alliance Station walls on the shorter side. The field features two sectors, with each containing one end for each alliance combined with the rendezvous point (center area). The sector contains robots at the start of each match, while drivers control their robots at the alliance station. The rendezvous point contains the Shield Generator and the Trenches.

Alliance Station
Each team has their own Alliance Station that is positioned at one of the ends of the field. The Alliance Station is where drivers control their robots, human players deliver game pieces to robots, and opposing alliance robots shoot game pieces. Alliance Stations contain three driver's stations, one for each participating team in the alliance. The center player station is flanked on one side by the loading bay, and on the other side by the opposing alliance's power port.

Loading Bay
Loading Bays are located in the alliance stations, with one per alliance. The Loading Bays are used by the human player to give game pieces to the robots on the field. There are five places that game pieces can be put into the Loading Bay, with two upper ports, and three ground ports.

Power Cell
Power Cells are the main game piece in Infinite Recharge. The Power Cell is a yellow, 7 in (~18 cm) diameter Medium Bounce Dino-Skin foam ball. The FIRST logo is printed in black ink on each Power Cell.

Shield Generator
The Shield Generator is a large box-shaped structure located in the center of the field.  It contains both alliances Rendezvous Points, as well as the two Generator Switches.

Trench Run
The Trench Run is an approximately 4 ft by 18 ft rectangular area on each side of the field bounded by alliance-colored tape that contains the alliance's Control Panel. It is located in the middle of the field, directly adjacent to the Shield Generator.

Scoring Areas

Power Port
There are two Power Ports on the field, with one at each Alliance Station. An alliance's Power Port is located at the opposing alliance's Alliance Station, requiring robots that intake from the Loading Bays to drive across the field in order to score Power Cells.  There are three levels of scoring on a Power Port. The rectangular Bottom Port is worth two points in autonomous, or one in the teleoperated (or teleop) period. The hexagonal Outer Port is located above the Bottom Port, and is worth four points during the autonomous period, and two points in teleop. The Inner Port is located inside of the Outer Port, and is a much smaller circular hole set in the back of the Outer Port.  It is worth six points in autonomous, and three during teleop.

Scoring Power Cells into the Power Port also contributes towards reaching Capacity, which is a count of the number of power cells scored, regardless of port. Certain levels of Capacity require additional tasks to be completed.  Lights around the Power Cell indicate progression towards reaching a stage's Capacity, lighting up in a chase pattern when Capacity is reached but the extra condition is yet to be fulfilled. Upon reaching Capacity and completing the stage's additional task, the stage is said to be Activated.

Control Panel
There are two Control Panels placed on either side of the middle of the field, in each alliance's Trench. They are large discs, with eight colored wedges (red, yellow, blue, and green, repeated once) printed on both the top and bottom. There is a glass panel on the bottom of the Control Panel, however, its wedges are still visible from underneath. After activating Stage 1 and reaching Stage 2's capacity, an alliance may score 10 points by performing Rotation Control on the Control Panel. This entails spinning the Control Panel at least 3 times, but not more than 5. Rotating past a fifth rotation resets this task, and the rotations must be completed again. After activating Stage 2 and reaching Stage 3's capacity, the alliance may score 20 points by performing Position Control. This entails rotating the Control Panel to a certain color specified by the Field Management System through a message sent to each team's driver's station. When complete, this energizes the Shield Generator, gaining the alliance one ranking point.

Rendezvous Point
An alliance's Rendezvous Point is located underneath the Shield generator, and is marked with each alliance's color on three sides, with the fourth side being a black line separating the two Rendezvous Points. Alliances gain 5 points for each robot parked there when the game ends or 25 for each robot hanging, which will be explained below.

Generator Switch
A Generator Switch is located above each alliance's Rendezvous Point, and is attached to the Shield Generator.  During the final 30 seconds of a match, robots may extend up and attach to the bar on the bottom of the switch.  Each robot attached to the switch and off the ground at the end of the match is worth 25 extra points. The switch is able to swing back and forth when robots attach to it, and there is an additional 15-point bonus for balancing the switch within ~8 degrees of level.  An additional ranking point will also be given to an alliance if their endgame score (i.e., that of climbing and parking) is 65 points or more, which makes the Shield Generator operational.

Scoring Summary

In qualification rounds, teams are ranked by their Ranking Score, or their average number of Ranking Points (RP) per match. To ensure high placement, it is not only important to win matches, but to complete the secondary objectives as well, to amass as many Ranking Points as possible.

Events 
The competition season for Infinite Recharge was planned to be divided into seven weeks, with many events occurring simultaneously during each week. After Week 7, teams that had qualified were scheduled to compete in the FIRST Championship, held over two weeks in Houston and Detroit. However, due to the coronavirus pandemic, a majority of these events including both championships were eventually cancelled. As a result, the final season covered only three weeks.

Postponed and Cancelled Events
On January 30, 2020, FIRST announced that the two Beijing Cultural Exchange regional events that were scheduled for Weeks 3 and 4 would be postponed until after the FIRST Championship due to the COVID-19 pandemic. As teams will not have an opportunity to qualify for the 2020 Championship through these events, teams that win Championship-qualifying awards at these two events will qualify for the 2021 Championship instead.

The Taichung Science Park regional, scheduled for Week 2, was postponed for the same reason.

On March 5, FIRST Washington announced that the Auburn Mountainview district event, scheduled for Week 2, was cancelled due to the coronavirus. This was the first event cancellation or postponement in the United States as a result of the outbreak.

On March 6, the Central New York regional, scheduled for Week 4, was postponed due to the coronavirus. The Mount Olive district event, scheduled for Week 2, was cancelled for the same reason.

On March 8, both Australian regionals were postponed due to the coronavirus. All FIRST in Michigan district events after Week 3 were also postponed.

At 10 AM on March 12, the Finger Lakes regional was cancelled due to the coronavirus following an announcement from the Monroe County health department, which restricted events over a size of 50 persons. The FIRST Chesapeake district also cancelled all remaining events, and rescheduled their district championship to June 17–20. Additionally, FIRST Mid-Atlantic has postponed all of its remaining events, including the district championship.

On March 12, 2020, FIRST announced that the 2020 season was suspended effective immediately. It was also announced that both FIRST Championship events would be cancelled.

On May 13, all suspended events were cancelled by FIRST. Additionally, it was announced that Infinite Recharge will be replayed in 2021 "with adjustments".
