Making human/robot interaction easier in future, the Wroclaw University of Technology in Poland has developed a robot that can display emotion.
Emys uses an animated neck, three discs and a set of eyes to express a range of nine different emotional states, from a difficult-to-discern anger to a comical surprise with sadness, disgust, weariness and joy mixed in, among others, reports the Telegraph.
The hope is that expressive robots like Emys would be able to become part of some people's lives in a way that currently only other humans or possibly pets can.
They aim to provide humans with 'friendly robots,' that would accompany them in their daily lives. Such friendly robots might act as care assistants, guides, entertainers or home helps.
