YouTuber mansooon0 apparently really, really likes his favorite anime characters. So much so that he doesn’t mind licking his computer screen in a show of affection.

Unfortunately, the act of licking his display was both messy and gross, so he put his DIY skills to the test and built a robot to do the licking for him. Using a fake “realistic” tongue, servo motor, and some Arduino circuitry, he designed the robot organ to be extremely simple to operate.
