Nao: the robot that expresses and detects emotions - Telegraph: "The humanoid machine, called Nao, hunches its shoulders when it feels sad and raises its arms for a hug when it feels happy.It has been designed to mimic the emotional skills of a one-year-old child and is capable of forming bonds with people who treat it with kindness. Nao is able to detect human emotions through a series of non-verbal “clues”, such as body-language and facial expressions, and becomes more adept at reading a person’s mood through prolonged interaction."
