The family of the jellyfish or medusae are not only the most venomous ocean inhabitants but also some of the deepest divers. Medusae have been found as deep as 8.300 meters. Their existence is paramount to the oceans. Many of the large migrations of fish and mammals would not be possible without the existence of jellies. They are a crucial part of the food chain, many fish feed on jellies and in turn mammals or larger migratory predators feed on fish.The scientist Gerhard Jarms of the Zoological Institute of the University of Hamburg takes us on a journey into the exotic world of jellyfish. He is one of the most renowned medusae scientists in the world. Our expedition begins in the northern Atlantic where we will find the mysterious periphylla. We will continue on to the Azores in the Atlantic. There we will search for the XY jellies that seek shelter in caves in rough seas.
In the Pacific we will swim with the jellies in the famous Jellyfish Lake and last but not
least we will explore some of the world's most beautiful coral reefs of western Papua. And at the very end danger lurks around every corner as we set out to search off Australia's coast for the fatal sea wasp- one of the most poisonous ocean inhabitants.

Self-Repair in Jellyfish - Goentoro Lab at Caltech

Published on Jun 17, 2015


Researchers at the Goentoro Lab at the California Institute of Technology have discovered a previously unobserved self-repair mechanism in juvenile jellyfish. Paper: "Self-repairing symmetry in jellyfish through mechanically driven reorganization", published in the June 15th online edition of Proceedings of the National Academy of Sciences (PNAS). Contributors to this work include Michael Abrams, Ty Basinger, William Yuan, Chin-Lin Guo, and Lea Goentoro.

Jellyfish inspired robots

Published on Jul 2, 2019


By connecting a magnetic composite elastomer core to eight bendable lappets, researchers created an untethered jellyfish-inspired soft millirobot. The lappets contract and recover like a swimming jellyfish when exposed to an oscillating magnetic field along the robot’s body central axis.The robots can perform various tasks and could be used to better understand jellyfish locomotion.

Bionic Jellyfish swim faster, more efficiently

Jul 29, 2020


Engineers at Caltech and Stanford University have developed a tiny prosthetic that enables jellyfish to swim faster and more efficiently than they normally do, without stressing the animals. The researchers behind the project envision a future in which jellyfish equipped with sensors could be directed to explore and record information about the ocean.

Meet the world's first cyborg jellyfish

Feb 14, 2020


Researchers from Stanford and Caltech have developed a way to control the swimming speed of live jellyfish using removable microelectronics. The intended goal of these first-of-their-kind cyborg jellyfish is to someday swim through our oceans measuring the impact and effects of climate change. Jellyfish were chosen for the experiment because of their energy-efficient way of swimming, their prevalence throughout various ocean ecosystems, and because they have no brains or known pain receptors.

Poly-saora robotic jellyfish

Robotic Jellyfish Actuted by TCP muscles

This video is a supplementary file associated with the paper published in Smart Materials and Structure (SMS). The full paper can be found from the link below. The video show the swimming motion of a jellyfish-like robot that is actuated by Twisted and Coiled Polymer ( TCP) muscles based on silver-coated nylon material, soft silicone and 3D printed thermoplastic .

Abstract
Jellyfish are energy-efficient swimmers due to the muscle-powered flapping of their soft bell that facilitates a unique energy recapture mechanism. In this paper, we present a bio-inspired jellyfish robot named Poly-Saora that mimics the swimming behavior of the jellyfish species Black sea nettle (Chrysaora achlyos). An assembly-based fabrication method is used to create the Poly-Saora that is developed mainly with polymeric materials (95% of the robot by volume). Twisted and coiled polymer (TCP) actuators are successfully implemented in this robot and show great potential for underwater applications. The influence of different parameters such as the amplitude of the input power, the actuation frequency, and the lifecycle of the actuator are investigated underwater. A full characterization of 6-ply TCP muscles is demonstrated. An actuation strain of ~10 % is achieved in water at a frequency of 0.1Hz and 50 kPa load. When integrated into the jellyfish, the TCP was able to bend a single bell by 17˚. Poly-Saora was able to swim a vertical distance of 180 mm in 220 s with four TCP actuators each confined in a separate conduit. The robot mimics the swimming behavior of a real jellyfish by contracting the bell segments through the activation of the actuators, which generates forced water circulation under the bell in a pulsating rhythm, consequently creating a vertical movement of the robot. Overall, Poly-Saora is presenting a model of an underwater system that is driven by stimuli-responsive polymer materials and has unique advantages over conventional rigid robots due to their lightweight, muscle-like structures, silent actuation and ease of manufacturing. This robot can be used for safe interaction with other underwater species and their natural habitats when fully developed.

Jellyfish-like robots could one day clean up the world’s oceans

Apr 25, 2023


Roboticists at the Max Planck Institute for Intelligent Systems in Stuttgart have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
