Peiqi Su is the mastermind behind this wonderful creation called the Penis Wall. Each robot penis on this wall is wired to a different stock. As the stocks go up, the penis goes erect. The stock goes down, the penis goes flaccid.
That’s it, and the result is amazing.
The penis is so different! This is my initial motivation, to study one of the oldest and probably the most attractive thing that humans interact with.
The Penis Wall is made up of 3D printed penises that each have six segments driven by servo motors. Equipped with an ultrasonic distance sensor, each unit can respond to a viewer’s movements. Moreover, the Penis Wall can also be used as a display to represent data, for instance, fluctuations in the stock market.
As she notes in her description, there is also a distance sensor wired to each one, so they can react to people in real time as well. You can see it interacting with someone in this video
in the video below you can see a breakdown of the mechanical structure. There’s a servo and an arduino in place to pull a string which erects the robot penis. Relieving pressure on the string allows it to return.
