Two six-foot humanoid robots scored a double knockout at REK2 in San Francisco
REK2 ran on the evening of August 15, 2026 at REK's San Francisco headquarters, billed by REK as the first six-foot humanoid robot fight in US history and streamed live on X. The machines are EngineAI T800 humanoids, roughly 1.73 m and 75 kg, each teleoperated in real time by a human in a VR rig. In the final, both robots went down in the same exchange; one stood back up, and the Japanese pilot listed as Osone took the title, his second REK win in a row, according to Japanese outlet Denfaminicogamer. REK posted the moment with the words "INSANE DOUBLE KNOCKOUT." EngineAI is based in Shenzhen; on July 29 the FCC banned new imports of foreign-made humanoid robots on national-security grounds.
