A robot that speaks 33 languages has become the world's first robot to guide tourists through a cave system. 

The Alistrati Cave in northern Greece began using Persephone, fittingly named after the Greek goddess of the underworld, in mid-July. The robot is able to offer information in 33 languages but is only able to interact in three.

Alistrati's scientific director Nikos Kartalis told The Associated Press he had the idea for Persephone after seeing an art gallery robot on TV. The resulting robot cost 118,000 euros ($139,000) to build, the report says.

In a translated Facebook post the Alistrati Cave management said the robot is part of an "innovation hub" which also includes a VR app and a classroom where students can learn about robots.

In other robot news, Elon Musk unveiled his own Telsa Bot yesterday which runs on the same AI used by Tesla's fleet of autonomous vehicles.
