Pompeii archaeological park has enlisted a four-legged robotic dog called Spot to inspect the ancient Italian city's streets and tunnels instead of humans. Acting as a robotic guard dog, Spot will patrol Pompeii at nighttime or whenever the site is closed to tourists, providing a live feed for human officials situated off-site. Part of Spot's job is to investigate tunnels dug by illegal relic hunters, which are causing structural issues but would be dangerous or too tight for officials to access safely. Spot, which is the product of US firm Boston Dynamics, is using its cameras and sensors to provide a feed of hard-to-reach Pompeii structures. It's capable of inspecting'even the smallest of spaces', gathering and recording data useful for planning interventions to fix safety and structural issues.
