Could schools of robot jellyfish soon be patrolling the world’s oceans, monitoring fragile environments such as coral reefs? That’s the dream of U.S. researchers, comprising of scientists from ...

Each robot works faster than other comparable inventions, reaching a speed of up to 6.1 cm/s. Moreover, Jellyfish-Bot only requires a low input power of around 100 mW.

Although jellyfish may not be the fastest animals in the ocean, they do swim in an energy-efficient manner – a manner that underwater robots might do well to copy. With that in mind, Chinese ...

Jellyfish-inspired robot that mimics the animal's efficient movement through the water could be used to explore coral reefs and archaeological sites The moon jellyfish — Aurelia aurita — is ...

By mimicking the way a larval jellyfish eats, the robot can capture objects. When a jellyfish swims, its contractions force water under its bell, and that water carries microorganisms.

In addition to improving the speed and movements, the battery technology extended the robot jellyfish’s runtime to an hour and a half. The robot itself was built atop technology the school ...

Technology Robots Robot jellyfish swarms could soon help clean the oceans of plastic By simulating jellyfish movement with artificial muscles, the robots can safely kick up ocean trash for recycling.

A quiet power supply provides electricity within, causing the robot to contract and expand. The result is a piece of machinery that can swim gracefully, quickly (6.1 centimeters per second), and ...

The RFB powering the jellyfish features a tendon that propels the robot upward when flexed into a bell shape. When the shape is relaxed, the robot sinks down.
