The findings, published in Science Robotics, demonstrate that the new underwater robot can swim as quickly and efficiently as the squid and jellyfish which inspired its design, potentially unlocking new possibilities for underwater exploration with its lightweight design and soft exterior.
(1) Co-author Dr Francesco Giorgio-Serchi, Lecturer and Chancellor's Fellow, at the School of Engineering, University of Edinburgh, said: (2) "The fascination for organisms such as squid, jellyfish and octopuses has been growing enormously because they are quite unique in that their lack of
supportive skeletal structure does not prevent them from outstanding feats of swimming."
The new robot was developed at the University of Southampton and is the first submersible to demonstrate the benefits of using resonance for underwater propulsion. Resonance refers to large vibrations that occur when applying a force at the ideal frequency, like pushing a child on a swing. This allows the robot to use very little power but generate large water jets to push itself forward.
(3) The simple but effective mechanism consists of rubber membrane enclosing eight 3D-printed flexible ribs, which together form a 'propulsive bell'. (4) First , a small piston in the top half of the robot taps this bell repeatedly so that it expands and then springs back. This mimics a jellyfish's swimming technique and produced the jets of fluid to propel the robot through the water. When the piston operates at with the correct frequency, the robot can move at one body length per second and match the efficiency of the Aurella aurita jellyfish.

Jawaban dan Penjelasan
Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.
Jawaban:
a. Submersible or submarine means “kapal selam” in Indonesian.
b. The subject = Co-author Dr Francesco Giorgio-Serchi, Lecturer and Chancellor's Fellow.
c. Main verb = enclosing
d. It’s called sequencer. Sequencers are words that organize your writing and speaking, like first, next, them, and finally. We often use that when we give intructions, describe a process, or tell stories. Using sequencers will organizes your ideas into sections and gives them an order.
e. In a sentence, “such as” typically functions as an introduction to an example or a list of examples in the middle of a sentence.
