Saya the robot teacher

IN what could be a way of the future, primary students in Tokyo are being taught by a robot.
Saya is the result of 15 years of research and is being tested as a teacher after working as a receptionist.
It is multilingual, can organise set tasks for pupils, call the roll and get angry when the kids misbehave.
Saya is just one example of Japan's determination to put a robot in every home by 2015.
