These robots will never work. A robot cannot hold the attention of or maintain control over a class of 30-40 students. As for AIDS testing... Koreans are pretty backwards when it comes to sex education and understanding the risks of transmission from HIV/AIDS. Rather than educating parents, the government is just giving in to parents who insist on native English speakers being tested.
If a native English speaker who was HIV positive was actually a risk simply because they were sharing a classroom with a child, then shouldn't all Korean teachers be tested as well? If just teaching a child poses a risk of transmission, then Koreans are a threat too. Parents and Korea in general seems to believe that HIV/AIDS is a foreigner only problem. That is dangerous thinking and needs to change.
