Robots are having special lessons in manners to learn how to behave so they can mix better with humans.
By playing games like pass-the-parcel, scientists are trying to find out how future robot companions should react to people in social situations.
Experts hope the study will help humans develop a code for the way humans and robots interact together.
The work was on show at London's Science Museum and is part of the European Cogniron robotics project.
