China's new humanoid robot walked so naturally that the CEO had to cut it's leg open to prove it wasn't human.

China's XPeng Robotics shocked audiences after unveiling a humanoid prototype named IRON, whose movements were so lifelike that many people believed it was a human in a suit. During a live demonstration, IRON's balance, posture shifts, and fluid walking closely mirrored natural human motion. To prove it wasn't a costume, XPeng's CEO went as far as cutting open the robot's leg on stage, revealing the mechanical mesh and internal systems beneath its synthetic skin. Powered by advanced motion-control algorithms and real-time sensory feedback, IRON can adapt to uneven surfaces and maintain stability much like the human body - showing just how fast humanoid robotics are advancing.
