Key points
- In November 2022, Impossible Metals deployed its Eureka I AUV to a depth of 25 meters, where it identified, harvested and brought multiple nodule-representative rocks to the surface.
- Eureka I hovers above the seafloor while collecting nodules, using sensors to navigate, identify and harvest, and a buoyancy engine to descend to depth and return with its load.
- During initial testing, Eureka I is tethered with a communication cable that allows switching between manual and autonomous control.
- The company positions the vehicle as an alternative to dredging-based nodule harvesting, targeting nickel and cobalt for battery production.
