Robot dog called in to help manage Pompeii

A four-legged robot called Spot has been deployed to wander around the ruins of ancient Pompeii, identifying structural and safety issues while delving underground to inspect tunnels dug by relic thieves.

The dog-like robot is the latest in a series of technologies used as part of a broader project to better manage the archaeological park since 2013, when Unesco threatened to add Pompeii to a list of world heritage sites in peril unless Italian authorities improved its preservation.

Until Spot came along, no technology of its kind had been developed for archaeological sites, according to Gabriel Zuchtriegel, the director of Pompeii archaeological park.

Park authorities have also experimented with a flying laser scanner capable of conducting 3D scans across the 66-hectare (163-acre) site.
