   In South Korea, many schools hire English teachers from abroad, but as you know, there are not so many English native teachers in South Korea. A team of engineers has created a robot that they hope will take the place of foreign teachers.

Robots will save schools money. The cost to build a robot and hire a Filipino teacher to work with it is around $20,000 a year. That is about half the cost of supporting a foreign teacher in South Korea. What’s more, robot teachers can make students have more fun learning English.

The robot teacher is called Engkey. She is about one meter tall and is white, egg-shaped. She takes a screen as her face. She can move around the classroom while speaking to students, reading books to them and dancing to music by moving her head and arms. So this robot is more than a video screen on wheels. But Engkey’s voice is not her own. They are controlled by English teachers in the Philippines (菲律宾). There is a camera in each of the robot teachers. With the help of the camera, English teachers in the Philippines can see and hear the students.

Engkey’s creators say that they don’t know how successful the robot is as a teacher now. But they hope that some day all schools in South Korea will have a robot in the classroom.
