San Francisco based company, REK, has just unveiled their brand new six-foot tall humanoid fighting robot at their warehouse event in the city. The machine in question is an EngineAI T800, the first of its kind imported to the United States. It wasn’t brought in for a factory floor or a research laboratory though. It was brought in to fight.
The event, covered by ABC7 San Francisco on June 25th, marked a significant moment in the development of robot combat sport in North America — and introduced a business model that’s beginning to emerge as a pattern across the US robot sports landscape.
From Four and a Half Feet to Six — What Changed
REK has been running humanoid robot fighting events in San Francisco for just over a year. Their previous machines stood four and a half feet tall. The T800 represents a substantial upgrade — not just in height but in the nature of what the competition looks like.
REK’s founder, who goes by Cix, was direct about what the new scale means for spectators. A strike from one of these machines, he said, would be like being hit by a motorized bat travelling at 100 miles per hour. The robots aren’t performing choreographed demonstrations. They’re fighting.
“With robots, size matters,” Cix said at the event.
The EngineAI T800 is the same robot model that has appeared in URKL — the Ultimate Robot Knockout Legend — combat league footage that has been circulating widely on social media in recent months. Its first appearance in the US arrived not through an industrial partnership, a technology demonstration or a research programme. It arrived through sport. That’s a meaningful data point about where commercial demand for this class of humanoid robot is currently coming from.
The REK Storefront — A New Kind of Robot Business
Beyond the fighting events themselves, REK is opening a permanent storefront in San Francisco that will function as a one-stop operation for humanoid robotics. Visitors will be able to watch robots perform, attend classes on how to walk and programme a humanoid machine, rent robots, purchase them, and bring in existing machines for repair and maintenance.
The model has a direct parallel on the East Coast. ProRL — the Professional Robotics League, which held America’s first professional robotics sports event in Boston’s Seaport District in April 2026 — is building a similar dual-purpose operation combining robot sports events with servicing and maintenance infrastructure for humanoid robots.
Two organizations, on opposite coasts, arriving at the same business model independently: use sport as the public-facing showcase, build the commercial infrastructure around it. It’s the same relationship Formula One has always had with automotive engineering — the competition drives the development; the development drives the commercial application.
Cix made the cultural reference point explicit; “We’re making Reel Steel a reality” he said at the event. And separately, describing the experience of watching the robots fight; “It’s effectively like Mortal Kombat blew out of a video game console and went into a piece of metal.”
Those aren’t PR lines. They’re the genuine framing of someone who has spent a year building robot fighting events from the ground up and is now watching the hardware catch up to the vision.
What Spectators Actually Saw
The warehouse event drew a crowd of spectators who encountered the T800 up close for the first time. The reactions captured by ABC7 reflected a consistent pattern — people arriving with science fiction as their reference point and finding the reality closer than they expected.
“Honestly, the big one — this one is insane, it’s Iron Man, you cannot tell me that’s not Iron Man right there,” said Kamran Karic, a San Francisco resident at the event.
Karmen Leung put it in longer context. “I think people have been talking about robots for many decades and it’s very cool to finally see it come into fruition and see them getting into a fight right now.”
The sound and physical presence of the machine was cited repeatedly. Cix noted that it’s the weight and the sound — not just the visual spectacle — that registers most powerfully when you’re in the same room as one of these robots. That’s a dimension that video footage doesn’t fully communicate, and it points toward why live robot combat events may develop a distinct audience of their own rather than simply competing with video content of the same fights.
Why This Matters Beyond San Francisco
The arrival of the first EngineAI T800 in the United States for sporting purposes sits alongside a series of milestones that have accumulated rapidly in 2026. A robot broke the human world record for the half-marathon in April. A robot beat a world-ranked table tennis professional in competitive play. The URKL professional humanoid combat league is running a full season in Shenzhen with a $1.4 million prize pool. RoboCup 2026 opens in Incheon, South Korea on June 30th.
REK’s San Francisco event adds a specific element to that picture: the first significant humanoid combat robot to arrive in the United States came for sport before it came for anything else. That sequence — sport preceding industrial application as the primary commercial driver — is worth watching as the humanoid robotics industry develops.
