Close-up of robotic jellyfish moving smoothly in the ocean

With its soft, gentle movement, it's not easy to tell that this is a robot jellyfish.

Coral reefs are the backbone of a diverse marine ecosystem, which is why scientists are working hard to understand what it takes to keep them healthy and sustainable. Photo: @andBeyond.

To study coral reefs and the creatures that live on the ocean floor, scientists sometimes deploy underwater drones. But these drones are not perfect ocean spies. Photo: @New Atlas.

Their propellers can tear apart coral reefs and harm living creatures. The drones can also be noisy, scaring off other marine animals. Photo: @ Strategic Partnerships.

Faced with this situation, Erik Engeberg, a mechanical engineer at Florida Atlantic University in Boca Raton, and his team developed a new gadget: a jellyfish-shaped robot that can act as a gentler and quieter ocean spy. Photo: @Erik Engeberg.



Soft and glides smoothly across the seafloor, so this jellyfish robot won't harm coral reefs, or disturb the animals living around it. In addition, this jellyfish robot also carries sensors to collect data on the ocean floor. Photo: @Erik Engeberg.

The robotic device has eight tentacles made of soft silicone rubber. A pump on the underside of the robot draws in seawater and feeds it into the tentacles. The water inflates the tentacles, causing them to stretch out. Photo: @Erik Engeberg.

Then the power to the pump is temporarily cut off. The tentacles now relax and water shoots back out of the holes on the underside of the device. The escaping water quickly pushes the jellyfish upwards. Photo: @Erik Engeberg.

The robot also has a cylindrical hard shell on top. This shell contains sensors, electronics that control the jellyfish, and data storage that allows experts to communicate wirelessly with the robot jellyfish remotely. Currently, the robot jellyfish is in the process of being completed. Photo: @Erik Engeberg.

The robot could carry a sensor to record ocean temperatures. The data it collects could help scientists map where and when the ocean is warming due to climate change. Photo: @Erik Engeberg.

“Through this robot jellyfish model, I have a deep desire to help endangered coral reefs around the world ,” he added. Erik Engeberg hopes his robot jellyfish will help scientists study the potential impacts of climate change on the seas. Photo: @Erik Engeberg.

Monitoring ocean temperatures and other data could also benefit humans, by warning of worsening conditions, says engineer Erik Engeberg. Warmer oceans can make hurricanes stronger and more destructive. Warmer waters also melt sea ice. That melted water raises sea levels. And rising sea levels can lead to coastal flooding, or the complete disappearance of low-lying islands. Photo: @Axios.
