Robots Get Fleshy Faces (and Smiles), New Research Says
Engineers in Japan are trying to get robots to imitate that particularly human expression: the smile.They created a face mask from human skin cells and attached it to robots using a new technique that hides the bond and is flexible enough to transform into a grimace or a soft smile.The effect is halfway between the terrifying Hannibal Lecter mask and the Gumby claymation figure.But scientists say the prototypes pave the way for more sophisticated robots, with an outer layer that is elastic and strong enough to protect the machine while making it more human-like.In addition to expressiveness, the "skin equivalent," as researchers call it, which is made in the laboratory from living skin cells, can scar and burn and even self-heal, according to a study published June 25 in the journal Cell R...
