This Robot That Moved So Smoothly They Literally Cut It Open to Prove It’s Not a Person

When XPENG unveiled its new humanoid robot IRON, people didn’t just raise eyebrows — they raised doubts. The robot’s movements, fluid and eerily humanlike, looked so real the audience suspected there might be a human operator hiding inside the suit. So XPENG did something bold: during the live reveal they cut open its synthetic limb on stage to show there was no person — only hardware.

What they revealed wasn’t a clever illusion but a genuine engineering feat: IRON has a flexible spine, an articulated joint structure, synthetic skin, and what XPENG calls “bionic muscles.” Its design — from the metal endoskeleton to the skin covering — aims to recreate humanlike motion and appearance, yet remain fully mechanical.

What’s under the hood

  • Degrees of freedom: IRON reportedly supports 82 degrees of freedom — including 22 per hand — allowing for highly articulated motion and subtle gestures.

  • Compute power: To run the joints, respond to inputs, and control movement dynamically, IRON relies on three custom AI chips, delivering a combined performance of 2,250 TOPS. That compute power helps translate perception into motion without visible latency or robotic stiffness.
  • Realistic design philosophy: XPENG describes IRON’s architecture as “born from within,” meaning its skeleton, muscle-like structure, and skin are all designed to mimic human anatomy — structural realism meant to facilitate more natural interactions.

Why this matters

In robotics, motion realism is one of the hardest challenges. Robots can be incredibly capable — but rare are the ones that can walk, gesture, balance, and react in ways that don’t instantly reveal their mechanical nature. With IRON, XPENG is testing the boundaries of those capabilities. A robot that moves convincingly like a human opens doors not just for industry automation, but for public-facing roles: reception, hospitality, assistance, even companionship.

The very fact that the on-stage “cutting open” was necessary says something too: in 2025, we’re in a world where mechanical limbs can pass for flesh-and-blood movements. When that happens, acceptance of humanoids becomes less about sci-fi and more about design, safety, and real-world use.
