Can a robot substitute a teacher?

Japan launched a robot teacher named Saya to walk into classrooms. The device is supposed to express six basic emotions – surprise, fear, disgust, anger, happiness, sadness – because its rubber skin is being pulled from the back with motors and wiring around the eyes and the mouth, unlike  more mechanical-looking robots like Honda Motor Co. Asimo put out this robot this time.

The use of this polemic technology is the issue in many major papers around the world, like Telegraph, from UK, and space-fan sites and media journals.

This blog “discussed” robot teachers much longer they popped up from the news.
