Archaeologist robot dives 1,000 meters underwater to inspect sunken ship

Scientists from Stanford University have developed an underwater archaeologist OceanOneK. Its upper part

humanoid shape, and the back looks like an industrial machine with eight multi-directional engines. They allow OceanOneK to carefully maneuver underwater at a record depth of 1,000 meters.

Tactile or sensory feedback systemrobot and stereoscopic vision create an incredibly realistic experience, say scientists who have already used the capabilities of OceanOneK. “It feels like you’re deep underwater, not aboard a ship, in the control center,” Osama Khatib, a robotics expert at Stanford University, told the university’s newspaper. Looking through the eyes of the OceanOneK robot and feeling the wreck of the Crispy with mechanical hands, the engineer even felt the resistance of the water.

OceanOneK's predecessor, OceanOne was built fordive depths up to 200 meters. To upgrade the model, the researchers fitted the hull with a special foam made of glass microspheres, which provide buoyancy and at the same time are able to withstand enormous pressure at a depth of 1 km. It is 100 times larger than usual. In addition, the robot's arms are filled with oil and a spring mechanism that compresses it in response to external pressure, preventing breakage and cushioning the electronics.

The engineers also updated many tiny components throughout the OceanOne body to minimize the amount of compressible air in its individual parts and keep the robot as compact as possible.
