The robot smiled back
Long interested in interactions between robots and humans, Columbia Engineering researchers have created EVA, a new autonomous robot with a soft and expressive face that responds to match the expressions of nearby humans. The idea for EVA took shape a few years ago, when my students and I began to notice that the robots in our lab were staring back at us through plastic, googly eyes, said Prof Hod Lipson, who led the team.
