If you’ve been in the market for a robotic butt for a bit of light spanking, then you’ll be pleased to hear SHIRI (Translated to english: “buttocks”) is here! This derrière is designed to express “various emotions with organic movement of the artificial muscles”, which I’m they discovered real butts do after a whole load of research but in reality it’s able to move in a similar manor to the human counterpart.
SHIRI is designed to tense or loosen up depending on the sensory input, from touching to spanking. The inner workings of the system can be seen in the video and it doesn’t look overly complex if you fancy recreating your own. If you’re not that interested and just want to check out a guy spanking a robotic ass, skip in to about 2:25.
