The project’s two-armed underwater robot is used for complex inspection and maintenance tasks.
But researchers say the more urgent need is for scientific exploration.

The techniques pioneered by van Rees could lead to new types of UAVs.
To study the ocean effectively, researchers need in-situ measurements with cameras and people aboard submersibles.
“That’s what crewed missions to the seafloor are like.”

Rae’s company HyperKelp isworking on a systemto monitor glacial meltwater coming off Greenland.
The measurements could give better estimates of global sea-level rise.
His nonprofit is partnering on innovative high-tech submersibles.
