English teachers always are very expensive in non-english countries. But South Korea has found its solution, they'are testing Engkey, a robotic teacher, in the Philippines.
Engkey will walk in class among students, will talk to them and teach them English language, and can do a little dance too. But its a little clumsy and ugly robot. It don't have human like figure, Instead of face it has a LED screen.
The developer say these robot will not require health care, no more sick leave, or vacation pay, but to get this teacher you must have to pay about $10,000 for one.
