Robots that feel pain react faster than humans

Touch something hot, and your hand snaps back before you even think. That split second matters.

Sensory nerves in your skin send a rapid signal to your spinal cord, which triggers your muscles right away. Your brain catches up later. Most robots cannot do this. When a humanoid robot touches something harmful, sensor data usually travels to a central processor, waits for analysis and then sends instructions back to the motors. Even tiny delays can lead to broken parts or dangerous interactions.
