Robot, can you say ‘Cheese’ | Columbia engineers build Emo, a silicon-clad robotic face that makes eye contact and uses two AI models to anticipate and replicate a person’s smile before the person actually smiles


Columbia engineers build Emo, a silicon-clad robotic face that makes eye contact and uses AI to anticipate and replicate a person’s smile before they do.

After training, which lasts a few hours, Emo could predict people’s facial expressions by observing tiny changes in their faces as they begin to form an intent to smile. Now, the robot can integrate human facial expressions as feedback,” said the study’s lead author Yuhang Hu, who is a PhD student at Columbia Engineering in Lipson’s lab. “Although this capability heralds a plethora of positive applications, ranging from home assistants to educational aids, it is incumbent upon developers and users to exercise prudence and ethical considerations,” says Lipson, James and Sally Scapa Professor of Innovation in the Department of Mechanical Engineering at Columbia Engineering, co-director of the Makerspace at Columbia, and a member of the Data Science Institute.
