Japanese researchers have recently developed a robot that is able to distinguish itself from others with a high degree of accuracy. Junichi Takeno and his team at Meiji University built a robot with an artificial nerve cell in it’s computer that screens input from its sensors to determine if it is interacting with a doppelganger, or a mirror image of itself. In Takeno’s tests, the robot was able to identify a mirror image of itself using a series of blinking LEDs with 70% accuracy, a number the team is working on perfecting.
