Biohybrid Jellyfish Robots Dive into Earth’s Final Frontier

Published:

Caltech researchers invented the biohybrid jellyfish robot to revolutionize ocean exploration. Cyborg jellyfish with modest electronics are effective data collectors.

The initiative, published in Bioinspiration & Biomimetics, seeks to fill this marine ecosystem knowledge gap. Biohybrid robotic jellyfish with prosthetic “hats” and electronic pacemakers move and transport modest data payloads.

Caltech Centennial Professor of Aeronautics and Mechanical Engineering John Dabiri sees these intelligent ventures as data-collection partners. They want to sail across the oceans to measure temperature, salinity, and oxygen content to study global climate change.

When mechanical robots imitated jellyfish swimming, biohybrid robots were considered. The scientists decided to enhance jellyfish to take advantage of their natural abilities in the sea after genuine jellyfish proved ineffective.

Simon Anuszczyk, a graduate student, created the ultimate invention that uses prosthetic “hats” to increase the effectiveness of biohybrid jellyfish. In a vertical aquarium, the team found they could swim 4.5 times faster than their wild counterparts and carry a burden. Biohybrid jellyfish, which will enable oceanographic study, are already a reality that will allow us to discover new marine worlds. The future offers many potentials to pilot these organisms for full-scale horizontal and vertical inspection, opening new ocean exploration and science doors.
