Sad robot or happy robot - which would you choose?
A zoo is helping scientists to understand how people react to varied emotions - except the pets are not animals, they are robots.
For a week, the public is being invited to the 'Robot Petting Zoo' at Bangor University - where robot vacuum cleaners display different behaviours.
It is a collaboration between resident artist Merel Bekking and Prof Emily Cross.
