RoboEarth, the world wide web for robots.

The RoboEarth system will be tested in a hospital setting.

A world wide web for robots to learn from each other and share information is being shown off for the first time.

Scientists behind RoboEarth will put it through its paces at Eindhoven University in a mocked-up hospital room.

Four robots will use the system to complete a series of tasks, including serving drinks to patients.

It is the culmination of a four-year project, funded by the European Union.

The eventual aim is that both robots and humans will be able to upload information to the cloud-based database, which would act as a kind of common brain for machines.
