Robotic Jellyfish is Spying Climate

0

To study about Coral reefs and the creatures live there, Scientists place underwater drones. Still, Drones are not sufficient as spies. Their propellers can rip up reefs and harm living things. Drones are noisy and it scares animals. For this, the scientists have answered over it and that is A new robot Jellyfish.

Introduction

Erik Engelberg is a mechanical engineer at Florida Atlantic University in Boca Raton. His team was working on it and developed a new gadget. This robot is quieter and gentler ocean spy. It is really soft and squishy that it glides silently through the water. So it won`t harm reefs and also don’t disturb animals living around them. This robot also carries a sensor to collect data.

About the Jellyfish Robot

The device has eight tentacles made of soft silicon rubber. Pumps on the undersides of the robot take in seawater and direct into the tentacles. The water inflates the tentacles which are making them stretch out. Then power to the pumps briefly cuts out. Then the tentacles relax and water shoots back out of holes on the underside of the device. That rapidly escaping water propels the jellyfish upwards.

The robot also has a hard cylindrical case on the top. This has the electronics which control the jellyfish and store data. One component allows wireless communication with jellyfish. So this means someone is there who can control or remotely steer the robot by making different tentacles move at different times. This hard case could hold sensors too.

The inspiration

The researchers had a practical reason for modeling their device on Jellyfish. Real jellyfish is a bit faster than it needs a small amount of power to travel from one point to another point. As per Engelberg, they wanted to really capture that quality in their Jellyfish.

Jellyfish is slow and moves very gently and so does the Robo-Jelly. So researchers think it won`t frighten marine animals. The soft body of this jellyfish helps it to monitor ecosystems without damaging them. It can also record the ocean temperature by carrying the sensor. Because of this data, it will help scientists map where and when the ocean is warming because of climate change.

As per David Gruber, Jellyfishes are excellent swimmers that they have been moving around oceans for millions of the years. David Gruber is a Marine Biologist at Baruch College in New York City who was not involved with the robot. Gruber says. “I am always impressed when scientists get ideas from nature.” This jellyfish is one of them.

Purpose

His team got motivation by fighting climate change. He gave a deep desire to help endangered reefs around the world. His hopes are with the Robo-Jellyfish, which will help researchers study the otherwise hidden impacts of climate change at sea. Tracking sea temperatures and other data can benefit people too, by warning of bad or worsening conditions. Warmer oceans can make storms more powerful and destructive. Warmer seawater also helps melt sea ice by eroding glaciers from below. That meltwater adds to rising sea levels. Higher seas can lead to coastal flooding, or make low-lying islands disappear altogether.
