Once again, the Japanese have excelled themselves in weirdness by creating a human looking robot that can sing so adorably called the Yamaha HRP-4C. By human looking I mean kind of like the puppets in Lazy Town human, obviously cartoony in a very manga style, but at the same time, human enough to make you think “that looks/sounds weird.” Obviously you need sound to watch this video clip of the Yamaha HRP-4C robot.
Another version is below, because of the close-ups, this one is a little more creepy.
