Robot Dog Climbs Mount Etna to Sniff Volcanic Gases — Here’s What It Found
ETH Zurich researchers sent a four-legged robot equipped with a mass spectrometer onto Mount Etna to autonomously sample volcanic gases in hazardous areas. The robot achieved up to 100% autonomy in some missions but struggled with wind and rough terrain, which scattered gas plumes and sometimes required manual control. The system detected sulfur dioxide, carbon dioxide, and five out of eight helium sources.
