A dance ensemble made up of robots? That's right. Sony's QRIO "Quest for cuRIOsity" robots combined artificial intelligence and dynamic technologies to move, gather information and dance. At 2 ft. (0.6 m) tall and 16 lb. (7 kg) apiece, QRIO was developed to be a humanoid entertainment robot. Sadly, the dancers were given the pink slip three years after being introduced in 2003.
