Robots: Can we trust them with our privacy?

Joss Wright is training a robot to freak people out. Wright, a computer scientist, is plotting an experiment with a humanoid robot called Nao. He and his colleagues plan to introduce this cute bot to people on the street and elsewhere – where it will deliberately invade their privacy. Upon meeting strangers, for example, Nao may use face-recognition software to dig up some detailed information online about them. Or, it may tap into their mobile phone's location tracking history, learn where they ate lunch yesterday, and ask what they thought of the soup.
