Who is fighting? How humanoid robots are piloted: motion capture, VR, remote control and autonomy

In a humanoid robot fight, the first question is who is actually throwing the punch. The answer differs from one league to the next, and it shapes everything a fan sees: the speed of the exchanges, how robots get up after a fall, and what a win says about the team behind the machine. Four approaches are in use today.

Motion capture: the athlete is the controller

At ARC's fight night at *SCAPE in Singapore on 7 October 2026, the pilots were martial artists from Muay Thai, MMA, boxing and kung fu, wearing full-body motion-capture suits. Software from the company Katena turned their body movements into robot movements in real time, according to Humanoids Daily, so the robots chose none of their moves themselves. A split screen put each pilot beside the robot they were driving, while a second screen showed how many health points each robot had left. Each team fielded a 35 kg Unitree G1 and a 75 kg EngineAI T800.

UFB follows the same mirroring idea. At a side event held alongside CES in January 2026 at the BattleBots Arena in Las Vegas, branded Ultimate Fighting Bots, each robot was teleoperated by a human whose movements it copied in real time, Humanoid Guide reported. The site saw it as a show for the public, not a scientific test.

VR cockpits and remote controls

REK in San Francisco pilots its robots from virtual reality. eWeek described the planned set-up in August 2025: pilots would wear VR headsets giving a cockpit view of the robot and use dedicated controllers, so that their punches and sword swings would be reproduced by the machine. In February 2026 Humanoids Daily still described REK's approach as VR control with a human in the loop. REK's chief technology officer previously worked on latency at Oculus. In October 2026 the San Francisco Standard described REK's bladed robots as remotely piloted by humans, and reported founder Cix Liv saying that autonomous fighting is still some way off.

The first CMG competition, held in Hangzhou on 25 May 2025, used Unitree G1 robots, 1.32 m tall and 35 kg, controlled in real time by four teams of human operators, Global Times reported. eWeek, in a July 2026 article, added that the operators steered them remotely with control devices and voice commands, in bouts of three two-minute rounds where a robot that failed to stand within eight seconds lost the round.

Commands plus onboard control

URKL takes a hybrid route. Every team gets the same EngineAI T800, so results depend mainly on software and strategy. A human operator sends high-level intent by handheld remote, such as where to move, when to advance or when to trigger a technique, while the robot's own systems handle balance and the execution of each move. The league's qualifiers included a recovery test: a robot starting on the floor had to stand up unaided and take a boxing stance, with the best score for doing it within 3 seconds and zero after 20 seconds.

The rules presented at URKL's launch in February 2026, as reported by Humanoids Daily, give a fallen robot 10 seconds to get up on its own. A team can then use one of two manual resets per match, and going past that limit means a technical knockout. According to Wikipedia's entry on the league, teams must also have their algorithms approved before each fight.

Why it matters

The control method tells you what a result measures. When a pilot in a suit or a VR cockpit drives the robot, the fight tests the human as much as the machine and the speed of the link between them. When the robot balances and recovers on its own, as URKL requires, a win also rewards the team's control software. No league in the sources we opened runs fully autonomous fights yet.
