- World Championship season 2 · 1 October 2026 – 31 March 2027
Nine cards held and every one sold out, and a six-month world championship announced for October. One title bout on record and no result sheet: the only account of it is a line in a news story.
Rules, in six lines
- Control
- Teleoperated
These are the rules of this competition. There is no such thing as “the rules of robot fighting”: every league writes its own, and that is why a bout here and a bout somewhere else are not the same event.
The season
- 1 October 2026 – 31 March 2027 World Championship, season 2 · United States · «tickets coming soon»
The organiser publishes its own schedule at ultimatebots.com/schedule. Nine cards held, every one of them sold out, and one season announced ahead: the first long season this sport has had. What it does not publish is a result sheet — the winners of those nine cards are not on the record anywhere we can cite.
