Do you see a yellow-dressed woman standing in this picture? She is watching the students who are studying together in the classroom. She is smiling friendly. Do you know that this woman is not a real human? but she is a "Robot Teacher".
We know that using robots is more effective than humans. You do not need to give them the wage, because they don't have necessity to eat food and drink. Moreover, We never find a robot doing a demontration to fight any policy. Robot only needs the energy to make them function. However, you must update the system of your robots regularly, or when they deviate from your programs.
It is possible to use robots for the countries with the wide region and the population are small. The government should distribute the facilities of studying well. By using robot teachers the problem can be solved. But, of course we cannot rely our psychological matters on them, for example: as a counselor.
