Renee Grogan at sustainable underwater mining solutions developer Impossible Metals envisions underwater robots as key to harvesting precious metals from the seafloor without harming the ecosystem.
High-technology products like solar panels, smartphones, and batteries for electric vehicles incorporate such metals.
Impossible Metals' Eureka used an artificial intelligence-driven retractable arm to pick rocks off the bottom of Lake Huron as part of a test run.
The company's long-term goal is to deploy a fleet of camera- and arm-equipped robots that could travel four miles underwater, plucking metal nodules while hovering over the ocean sand.
Grogan said she believes her company is about "halfway down the path" to a time when the robots will be used for deep-sea mining, with commercial-scale deployment anticipated within five years.
