Ready to smack some robot ass? You can if you want to. Meet Shiri.
What is Shiri? Nobuhiro Takahashi and his team at the Tokyo University of Electro-Communications describe their creation in the video above as "a buttocks humanoid robot that expresses various emotions with organic movement of the artificial muscles."
So basically, a robot butt that clenches, twitches and responds to slaps like a person butt. Seriously, check the out the video for more details and a look inside how Shiri was made. The smacking action starts around the 2:25 mark.
According to the Japanse dictionary app Kotoba, "shiri" most commonly means buttocks. But using a different set of Japanese characters with the same pronunciation, the word takes a second meaning -- "personal profit, self interest."
