The iCub robot baby was shown in IROS 2011 event, mimicking a young human being crawling on the floor. Though the robot baby looks like a scary baby from a horror movie, it is designed to emulate a three and a half year-old child and intended to explore how human cognition develops, using facial expressions and adaptive learning techniques. Sometimes those facial expressions don’t work out so well, or is able to crawl very well.
