The Robot Combat League is a non-profit whose mission is to promote STEM and design and fabrication skills through the exciting sport of Robot Combat.
How RCL works
Robot Combat League is a national robot competition federation, not an official organizing body for Robot Combat. Launched in March 2022, it draws competitors from local events in the USA to participate at a national level. Although most local events in the League use the SPARC rule set or some variant, every event participating in the league is independent and can run their event as they see fit, so long as they fit into a very broad set of guidelines. More than 30 independent events have agreed to use the League event results tracking system that will help determine which bots are the top competitors in the USA. Highly ranked bots will be considered candidates for the Robot Combat League competition.
Qualifying weight classes
As of 2022, ranks are calculated for the most popular weight classes: 150g, 1lb, 1lb Plastic, 3lb, 12lb, 30lb, and 30lb Sportsman robots. If more weight classes become popular and events want to include them in the League, the ranked classes may be expanded.
Determining points and rankings
Robots earn points by how highly they place at events they participate in. A robot's season total is taken from their top 3 - highest point events, provided there are at least 5 competitors in the same weight class competing.
Points are determined by how well a robot places in a competition, and is weighted by the number of robots competing. The exact calculations to determine a robots score can be viewed on this calculator.
The league season
The season starts the first day of March and ends on the last day of February. Competitions in this time period are considered qualifiers for the next event. With the 2022 season being the first, adjustments to the season dates may be made if needed. Event data prior to March 2022 isn't complete, so take historical rankings with a grain of salt.
The first season ran from March, 2022 to February, 2023 and the first competition is scheduled for May, 2023 in Seattle, Washington. Since an appropriate arena is not available for this event, 30lb destructive bots will not be able to compete this year.
Why the Robot Combat League doesn't use the SPARC Botrank system
Although the SPARC Botrank system made an attempt at tracking how well robots performed, their system had several shortcomings.
- The primary problem with Botrank is that scores are greatly influenced by the number of events a bot has competed in; bots that competed a lot were favored over those that placed highly in events. This led to situations where a bot that competed and performed 'OK' in a half dozen events would be ranked higher than a robot that competed in and won two events.
- Another issue is that Botrank rankings are adjusted based on an 18-month rolling time period. While this captures recent performance well, having no defined seasons or periods where rankings would be set makes its calculations ever changing and difficult to evaluate.
- The SPARC Botrank system didn't have a way to disambiguate robots with the same name. Common robot names like 'Hazard' made the results unreliable.
