Xiaomi's Humanoid Robots Keep Pace on Car Assembly Line

Robots that walk on two legs are now building cars alongside human workers, and they're keeping up with the pace.

Chinese tech giant Xiaomi recently tested two humanoid robots at its electric vehicle factory in Beijing, where the mechanical workers spent three hours installing lug nuts on car chassis. The robots successfully completed 90.2% of their work, matching the factory's demanding rhythm of one car rolling off the line every 76 seconds.

"The robots in our production lines weren't doing an official job, more like the interns," Xiaomi president Lu Weibing told CNBC. But these "interns" achieved something remarkable: they proved that truly bipedal robots can handle precision tasks in a real production environment.

The trial video shows the two robots positioned at opposite ends of the assembly line, carefully placing small parts with pinpoint accuracy. While human workers might complete the task faster right now, the robots managed to keep pace without breaks, mistakes from fatigue, or the need to pause for bathroom trips.

The biggest challenge wasn't teaching the robots to do the work. It was making sure they could match the speed of everything else happening around them in a factory designed for human efficiency.

Why This Inspires

This achievement represents more than just robots doing factory work. China has already deployed more industrial robots than any other country, but those machines typically stay bolted in one spot. These Xiaomi robots walked, balanced, and adapted to their surroundings just like their human coworkers.

Xiaomi isn't alone in this race. A UK company called Humanoid completed a similar pilot in February with over 90% success in stacking tasks, though their robots used a stable base instead of walking on two legs. The difference matters because truly bipedal robots can navigate spaces designed for humans without requiring factories to rebuild their entire layout.

Lu keeps expectations measured, calling this an internship rather than a full employment offer. But the fact that multiple companies worldwide are successfully testing humanoid robots in real production settings signals a turning point.

The technology is moving from science fiction to factory floor faster than most people expected.
