URKL opened publicly at Shenzhen's Nanshan Culture and Sports Center on 16 July 2026. A Shenzhen government report records five rounds between two T800 robots, with Bullfighter defeating White Eagle by a 3–2 decision. The league has published detailed qualification rules. Its main-match rules remain incomplete.
One platform, three team roles
EngineAI designates its own T800 as the competition robot, removing differences in height, mass and actuator layout between unrelated machines. The rules identify operators, technical maintenance personnel and coaches. Each entry is therefore a team effort with distinct human responsibilities.
Over 200 teams from China, the United States, Poland and Singapore registered, according to the Shenzhen report. The rulebook advances 32 teams from qualification to on-site deployment. Sixteen then enter the group stage, divided into four groups for a double round robin; eight progress to the finals bracket.
Qualification tests software before combat
The online stage gives teams a T800 model, simulation files and sample motion data. EngineAI provides human skeletal boxing motion and T800-remapped data at 30 Hz, with a MuJoCo-compatible environment. The scored tasks include recovery from a fall, locomotion, strike execution and motion fidelity.
The online stage acts as a software and deployment filter. It tests whether teams can work with the supplied body and reproduce stable behaviours before receiving access to physical competition hardware. The top 16 teams are promised ownership of a T800, while the champion prize is described as worth up to RMB 10 million.
The match rules are still the missing document
The published calendar places group matches in August and September, quarterfinals in October and November, and the last rounds from December into January 2027. It also describes a double-elimination phase. The section covering the main tournament format remains unpublished.
The public document leaves material questions unanswered: exact scoring, round length, permitted contact, stoppage authority, repair windows, control mode and the footage available for appeals. Until those fields are published, the 3–2 launch result cannot be reconstructed from the rulebook.
This account is based on organizer rules and a Shenzhen government report. ClankerSports has not observed team deployment or independently tested the competition hardware.
