Scientists at the Columbia Institute of Engineering in the United States have been working on an autonomous robot-android called EVA for five years.
According to the university’s website, experts have finally been able to teach the robot to express their feelings through facial expressions. The robot is able to express six emotions – anger, disgust, fear, joy, sadness and surprise.
Note that the robot is mainly made of metal and hard plastic. Many parts of it were printed on a 3D printer.
