Robots as companions: Are we ready?

A bit more about how Pepper works. In the final version, Pepper will be able to understand 5 basic emotional expressions of the face: smiling, frowning, surprise, anger & sadness. Pepper will also read the tone of your voice, the verbage used, as well as non verbal communication such a tilting your head. So for example, if you're feeling sad, Pepper may suggest you go out. If you're feeling happy, Pepper may sing a song and do a dance for you (more on that later).
