Affetto is a robot that can smile at you while it pierces your soul with its endless, dead state. Created by researchers at Osaka University, this crazy baby-head robot can mimic human emotions by scrunching up its nose, smiling and even closing its eyes and frowning. Put it all together and you get a nightmare from which there is no sane awakening!

A trio of researchers at Osaka University has now found a method for identifying and quantitatively evaluating facial movements on their android robot child head. Named Affetto, the android’s first-generation model was reported in a 2011 publication. The researchers have now found a system to make the second-generation Affetto more expressive. Their findings offer a path for androids to express greater ranges of emotion, and ultimately have deeper interaction with humans.

The researchers investigated 116 different facial points on Affetto to measure its three-dimensional movement. Facial points were underpinned by so-called deformation units. Each unit comprises a set of mechanisms that create a distinctive facial contortion, such as lowering or raising of part of a lip or eyelid. Measurements from these were then subjected to a mathematical model to quantify their surface motion patterns.
