There are lots of lonely people out there, and when these people get crafty with robots, all kinds of creepy things can happen. You see, Japanese YouTuber Mansooon0 likes to lick his computer screen as a way to “worship” his favorite anime characters. Sounds reasonable.
Necessity truly is the mother of invention. Mansooon0 got tired of always wiping saliva off his screen, so he came up with a solution. No, he didn’t just stop acting like a weirdo and keep his tongue in his mouth. Instead, he built a simple device to do the screen licking for him. A robot tongue. You might call it a Tongue-inator.
He used a servo motor, a realistic silicone tongue and some Arduino circuitry to build it. Creepy yet effective, this robot tongue will lick Anime girls all day long, right up until the cops come and ask to see your album of newspaper clippings. You know, the ones with the headlines that line up with the string of recent disappearances in your area.
