WHAT YOU NEED TO KNOW
- Frankie LaPenna faced three humanoid robots during a cage fighting event staged by REK in San Francisco.
- Human pilots controlled the robots, while artificial intelligence assisted with balance and trained movement.
- REK says its modified EngineAI T800 machines can kick with up to 850 pounds of force.
- LaPenna was knocked down and injured his hand, but ultimately finished one bout with the robot’s head coming off.
Content creator Frankie LaPenna turned a robotics showcase into a viral spectacle by stepping inside a cage with humanoid machines.
In San Francisco, he faced three robots across a series of bouts that put a person directly against powerful metal opponents, as reported by Fox News.
The event was staged by REK, a robotics entertainment company that places remotely controlled humanoids into live combat events.
REK billed the showdown as the first cage fight between a human and a humanoid robot.
The footage attracting the most attention shows LaPenna advancing toward an EngineAI T800 and throwing several punches.
The robot responds with punches and kicks before a forceful shot sends LaPenna flying across the cage.

Its mechanical head and glowing red eyes give the machine a clear resemblance to The Terminator.
Beyond that theatrical appearance, however, the encounter offered a striking display of how humanoid robots can move, absorb contact, and remain balanced during physical combat.

LaPenna first faced a smaller Unitree G1 before confronting two modified EngineAI T800 machines.
The T800 is built by Chinese robotics company EngineAI, which lists the standard model at about 5 feet 8 inches tall and roughly 165 to 187 pounds, depending on the version.
REK describes the modified T800 machines used in its fights as standing about 6 feet tall.
Placing machines of that size inside a confined fighting cage helped turn the footage into an especially intense demonstration.
The crucial detail is that the robots were not choosing to fight LaPenna independently.
REK technology partner Reflex Arc says human pilots operate the humanoids in real time through virtual reality equipment or a gamepad.
Artificial intelligence assists with balance and trained movement, while the pilot directs the robot’s actions.
Each punch and kick follows a human command, even though the machine must translate that instruction into physical movement while staying upright and recovering from contact.
According to REK CEO Cix Liv, LaPenna fought three robots during the event. He began with the smaller Unitree G1 and then moved on to the two modified T800 humanoids.
REK says its modified T800 machines can kick with up to 850 pounds of force.
That capability helps explain the dramatic sight of LaPenna being knocked down during one of the T800 bouts.
Liv said LaPenna recovered, knocked the robot off balance, and ultimately finished the fight with the machine’s head coming off.
REK has continued teasing additional footage, while the short clips circulating online show only part of the full sequence involving all three robots.
LaPenna initially wanted to fight without protective equipment, according to Liv, but REK insisted that he wear it.
He entered the cage in motorcycle protective gear and gloves, injured his hand while punching one robot and otherwise avoided serious injury.
REK has already been staging fights in which people remotely control humanoid robots against other humanoid robots.
The company also operates a simulator that lets players learn the controls before some receive an opportunity to pilot the physical machines.
Reflex Arc says REK’s first simulator championship produced 3,670 matches.
The winners were flown to San Francisco to control real robots at REK2 in August, using the same basic controls and trained balance system found in the simulator.
Humanoid robot combat had appeared before LaPenna entered the cage.
In 2025, four Unitree G1 humanoids controlled by human operators competed in a boxing tournament in China that featured punches, kicks, and knockdowns.
Other humanoids have played soccer without human control, rallied on a tennis court and kicked soccer balls hard enough to leave visible dents in a wall.
REK’s event pushed the spectacle in another direction by letting a human participant experience the machines’ physical strength directly.
Behind the Terminator styling and social media theatrics was a substantial robotics demonstration.
Machines weighing as much as about 187 pounds remained balanced in a restricted space, absorbed contact and executed forceful movements under human control.
The robots did not independently decide to attack, but their ability to carry out a pilot’s commands made the danger tangible.
LaPenna’s knockdown, hand injury, and protective gear showed that remote control does not make trading blows with a heavy humanoid machine harmless.
