Robot seals are being used to comfort earthquake and tsunami refugees in Japan.

The robots have sensors and an artificial intelligence system that allows them to react when being touched or spoken to.

Researchers say the cuddly seals in shelters can actually help people to cope with the feeling of isolation and the separation from friends and family.
