Today on Engineering Newswire, we’re exploring the ocean in a private submarine, translating vibrations into audio signals, and gaining superhuman strength ... with the help of a robotic exoskeleton. This episode features:

Super Yacht Sub: Capable of diving down to depths of 300 meters with three people aboard, the Super Yacht Sub 3 is powered by six thrusters running on a 42 kWh lithium-ion battery system, which takes around four to six hours to charge and provides up to 12 hours of run time.

According to the company, the defining feature of the Super Yacht Sub 3 is the ingenious Freeboard Extender. The patent-pending system makes sure the deep sea explorers can open the hatch at the surface even when waves are high.

Seeing Is Hearing: Researchers at MIT, Microsoft and Adobe have created an algorithm that can analyze tiny vibrations of objects in a video, and translate the vibrations into an audio signal.

The technique passes successive frames of video through a battery of image filters, which are used to measure fluctuations, like changing color values at boundaries, at several different orientations and scales.

Robotic Exoskeleton: Daewoo Shipbuilding and Marine Engineering is participating in a pilot program, outfitting employees with robot exoskeletons to help them do their jobs, with superhuman strength.

The Robo-Shipbuilder prototype suit is made of carbon, aluminum alloy and steel, and weighs only 28 kilograms.
