(AFP/File) - An engineering student soothes Yotaro, a robot which emulates a real baby at Tsukuba University in Japan. Yotaro's face, made of soft translucent silicon with a rosy hue, is backlit by a projector connected to a computer to simulate crying, sneezing, sleeping and smiling, while a speaker can let out bursts of baby giggles.(AFP/File/Kazuhiro Nogi)
