Robot Teacher for Japan

As if teachers are worried about their jobs enough as it is, now we have to beware of technology. It seems that a Japanese inventor has designed a robot to teach in Japanese Primary schools. Named Saha, the robot can take role, give lessons from a prepared text, even shows emotion. Of course, I am wondering how the robot will do answering questions like "Why does Johnny stand up when he goes pee" and chasing after young students who don't understand what they are supposed to do.
