A robot named ‘Emo’ can out-smile you by 840 milliseconds

If you want your humanoid robot to realistically simulate facial expressions, it’s all about timing. And for the past five years, engineers at Columbia University’s Creative Machines Lab have been honing their robot’s reflexes down to the millisecond. Their results, detailed in a new study published in Science Robotics, are now available to see for yourself.

Meet Emo, the robot head capable of anticipating and mirroring human facial expressions, including smiles, within 840 milliseconds. But whether or not you’ll be left smiling at the end of the demonstration video remains to be seen.
