A robot capable of mimicking human facial expressions has been developed by engineers at Columbia University in the US.

Engineers at the Creative Machines Lab in the university have developed 'Emo', a robot face which researchers believe is a significant advancement in non-verbal communication between humans and robots.

The study's lead author explained how the team faced the challenges of developing a mechanically expressive face and determining when to generate natural, timely expressions. "As robots become more advanced and complicated like those powered by AI models, there's a growing need to make these interactions more intuitive."

The robot was trained using a process termed"self-modeling", wherein Emo made random movements in front of a camera, learning the correlation between its facial expressions and motor commands. After observing videos of human expressions, Emo could predict people's facial expressions by noting minor changes as they intend to smile.
