Chinese scientists develop robot with human-like facial features

A Chinese scientist and a team of researchers have developed a robot that can display highly expressive human-like facial features.

The robot developed by Liu Xiaofeng, a professor at Hohai University in East China’s Jiangsu Province, and his research team is thought to have absorbed the feature after formulating a new algorithm for generating facial expressions in humanoid robots.

According to Liu, the inability of humanoid robots to mimic the nuanced and authentic facial emotions displayed by humans makes it difficult to attract consumers.

The researchers addressed this problem by developing a comprehensive two-phase method to increase the range of realistic facial expressions that a self-organizing emotional robot can depict.

Liu said their approach was the first to produce images of complex robot facial expressions led by artificial units.

They created an effective robot in the second stage with several degrees of freedom for facial movements, allowing it to imitate subtle artificially generated facial expressions.

“To maintain AU integrity while reducing identity noise, we leverage latent facial attribute space to separate expression-related and expression-unrelated cues, using only the former for expression synthesis,” the researchers said in the study.

“In the next phase, we realize an affective robot equipped with multiple degrees of freedom for facial movements, which facilitates the realization of synthesized subtle facial expressions.”
