The University of California, San Diego has been working on its robot baby for a few years now, but the first video of the faux infant has finally emerged. The Machine Perception Lab at UCSD created Diego-san in coordination with Kokoro and Hanson Robotics to better understand the cognitive development of children. The end result is incredibly intricate: the body contains 44 pneumatic joints. In fact, the head alone contains 27 individual moving parts. The face is especially detailed — even if it is somewhat unsetlling — with Diego-san able to mimic a wide variety of expressions. The video below will give you a good idea of the unnatural faces that the robot baby can produce — just don’t watch it right before you to bed.
