On July 16, 2026, the world's first humanoid robot fighting tournament—the ENGINEAI Ultimate Robot Knock-out League (URKL)—kicked off in Shenzhen. A total of 32 corporate, university and individual teams from multiple regions (including China, the United States, Poland and Singapore) competed in an octagonal cage. In the opening bout, a T800 robot named "Matador" had its head kicked clean off by its opponent. Stunned spectators watched as it continued punching using its core torso system, eventually winning the match. Tesla CEO Elon Musk shared the viral clip on social media, commenting, "Robot fights are fun." Martial arts star Donnie Yen attended as a special guest, describing the real-life battle as "more thrilling than movie special effects." The tournament follows a four-round structure—qualifying, play‑in, group stage and finals— leading up to the global finals in December. This year's competition uses the ENGINEAI T800 full‑sized humanoid robot as a standard platform, with open software and hardware interfaces allowing teams to perform secondary development. Up for grabs for the champions? A 10-kilogram pure gold belt worth roughly 10 million yuan (about $1.4 million). (Compiled by intern Dai Jiawei)
