Close Encounters: When Daniel123 Met Jane234
A Qbo robot can tell in real time whether it sees its own image reflected in a mirror or another Qbo robot in front of it, the development team's blog says.

The developers of the Qbo robots continue to explore simulated consciousness. After training a Qbo to recognize itself in the mirror, Francisco Paz and his team have trained a pair of robots to recognize each other. A video shows a green Daniel123 following a command to turn around, encountering a blue Jane234, and Daniel appearing to be aware that Jane is a Qbo. The robots were programmed to generate nose flashes to distinguish that there is another individual robot.
"Using nose signals to see if the image seen by the robot matches its action, a Qbo can tell in real time whether he sees his image reflected in a mirror or he is watching another Qbo in front of him," according to a post on the team's blog. "The sequence of flashes of the nose is randomly generated in each process of recognition, so the probability that two robots generate the same sequence is very low, and even lower that they start to transmit at the same time."
The open source Qbo robot runs on Linux, has two cameras with stereoscopic vision, and uses recognition software. Qbo robots talk to each other through Festival, a speech synthesis system, and Julius, a speech recognition engine.
