This is a "robot mouth" developed by Professor Hideyuki Sawada. It is, uh, "singing" a Japanese nursery rhyme called "Kagome Kagome." Fear not! Its intentions—"to help hearing-impaired people improve their speech"—are noble. So far. Soon, its horrible moans will provide the soundtrack to the ritualistic setting afire of human flesh in the "Robot Spring" of 2017. Perhaps if you learn to mimic its mechanical wail you will be allowed to live, in some kind of serving capacity. Probably not, though. [via PopSci]
