Similar to the movements of jellyfish, scientists have developed a new device namely jellyfish robots. A team at Florida Atlantic University revealed an 8 inch wide jelly-bot. It will monitor marine life and harsh underwater habitats. This device is based on the structure of a moon jellyfish. Interestingly, they are able to squeeze through holes cut in plexi-glass plates.
The researchers are quite sure that these jellyfish robots can now be sent to ocean to trace fragile coral reefs. They will not risk collision and damage the ocean. Instead of hard material, Florida developers have used soft substances for both the body and tentacles. Jellyfish robots can swim against currents just like the fishes. It can also swim through the holes which are smaller than its size.
Design and Function of Jellyfish robots:
The jellyfish robots contain two pumps to inflate eight silicon rubber tentacles. The pump creates a circuit of water for a swimming stroke. It then stops and the water flows back into ocean and the tentacles relax. Both the pumps of these jellyfish robots features a 3-volt battery running a small electronic circuit board. It also sports temperature and salinity sensors.
Dr Erik Engeberg, from Florida Atlantic University, said, “Studying and monitoring fragile environments, such as coral reefs, has always been challenging for marine researchers.” He further added, “Soft robots have great potential to help with this.” “Soft robots based on fish and other marine animals have gained popularity in the research community in the last few years. Jellyfish are excellent candidates because they are very efficient swimmers,” Dr Engeberg continued.
Meanwhile, five jellyfish robots of different hardness variants were created with the help of 3D Printing technology. “We found the robots were able to swim through openings narrower than the nominal diameter of the robot,” added Dr Engeberg.
However, this project is just a start to monitor oceans. Scientists are going to use navigational programming and environmental sensors further. This will help the jellyfish robots to find gaps and swim in a better way in variable water conditions. Click here for more such wild articles.
