For robots which accompany larger competitors which weigh under 20lbs, see Minibots.
Multibots is the name given to BattleBots competitors made up of two or more different robots, typically of a similar weight. Since 2019, changes to the BattleBots Design Rules which put an upper weight limit on minibots have dictated that if the lightest robot weighs over 20lbs, the overall entry qualifies as a multibot.
The rules concerning multibot immobilization have changed over time. Originally, if more than half of the combined weight of the multibot is immobile, then a knockout could be declared. This was true as of the 2009 Championships under Section 7.4.7 of their ruleset.[1] However, as per Section 7.5.4 of the 2016 Tournament Rules, this was increased to 60%.[2] This rule went unaltered for future World Championship seasons. This rule may have also been in place for the 2015 season, though a Tournament Rules document for that year is not publicly available.
Advantages:[]
- Multibots are typically lighter than individual heavyweights and are thus easier to carry around.
- One part of a multibot can serve as a distraction to help when another part is in trouble, or even help its partner escape danger.
- Depending on the weight distribution, they can be harder to defeat by knockout by virtue of more than one robot needing to be immobilized.
Disadvantages:[]
- Since they have to add up or be within the weight limit of the competition they're registered for, they generally come in at a weight disadvantage individually when compared to regular robots at the full weight.
- There are typically at least twice as many components to maintain, though they can be shared between all robots.
- Multibots require additional coordination for drivers to use them effectively.
- Multibots with kinetic weapons may accidentally hit one another rather than their opponent, as proven in Gemini's matches against Lucky and The Four Horsemen.
