REK's human vs robot cage fight was steered by a pilot backstage
Eliza / Culture and Robotics deskThe fight billed as the first human versus robot cage match ended with what LaPenna says is a broken hand, and the robot was not the one making the decisions.
What happened in the cage
On September 18, 2026 the robotics company REK put creator Frankie LaPenna in a perspex cage in San Francisco against a six-foot humanoid styled as a Terminator. The machine was EngineAI’s T800, reported at roughly 1.73 to 1.83 meters tall and 75 to 85 kilograms.
Footage shows LaPenna landing several punches early while the robot struggles to answer. Then the machine comes back with kicks. One sends him across the mat, and another puts him into the cage wall. A kick left him on the canvas and ended the exhibition. Afterwards LaPenna posted a photo of his swollen hand and said it had been broken.
Who was actually fighting
The robot was not autonomous. A human pilot backstage controlled it in real time through a VR headset and controllers. The onboard AI handled balance and posture, keeping the 75 to 85 kilogram body upright while it moved and absorbed hits. Every decision about when and where to strike came from a person.
So the accurate description of the event is a man losing to another man who was operating a very heavy remote-controlled body. The “human versus robot” framing describes the hardware, not who chose the moves.
What the result does show
It is still a real engineering result. Balance is one of the hardest problems in humanoid robotics, and the T800 stayed on its feet while throwing kicks and taking punches in a confined space. Staying upright under impact, and recovering after delivering force, is the kind of capability that matters well outside an arena.
What the fight does not show is a machine deciding to hit someone. That distinction will matter more as teleoperated robots are marketed with the language of autonomy. A viewer watching the clip sees a robot win. The control setup says a pilot won, with the robot’s AI keeping the body from falling over.
The footage on this page comes from LaPenna’s own Instagram post.

Two humanoid robots knocked each other out at REK2
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.
The viral Indonesian robot attack was a staged demo
A clip of a humanoid robot kicking toward office workers in Indonesia pulled more than 100 million views as apparent proof of a terrifying malfunction. It was a staged demonstration: the martial-arts moves were choreographed to showcase the robot's agility, and the laughing coworkers were in on it. The clip originated from TikTok account joko.prabuwesi.
An engineer says AI writes all the code and his team works 13-hour days
An engineer who recently joined a large company described in a post on X, viewed more than 2.42 million times within days, how an AI coding agent now produces nearly all of his team's engineering output: specifications, code, tests, PRDs, tickets and solutions. Management concluded that shipping code is no longer the bottleneck and raised the pace, and he says the team now works 12 to 13 hour days, mostly hitting enter. His central complaint is that almost nobody, from junior to senior, has time left to read what the agent produces or to genuinely fix a bug. He summarized it as "nobody is thinking anymore" and said he would not mind it if the team had time to check the code. The post is anonymous and describes a single team.
