A poke ball to catch aquatic animals and release safely underwater

The open ocean is the least explored and largest ocean on the Earth that could hold up a million species that yet to be explored. Many of them might be soft-bodies such as jellyfish and octopus which are difficult to catch for studies with existing tools. A new tool developed by the researchers at the Harvard University’s Wyss Institute, John A is able to trap these sea animals inside the polyhedral structure of the device and release them without harming them.

These deep-sea organisms are might be thousands of year old that deserves to be treated well with a gentleness, said David Gruber the coauthor of the study, National Geographic Explorer, Radcliffe Fellow, and Professor of Biology and Environment at Baruch College, CUNY.

This idea was first implemented by the Zhi Ern Teoh student of Chuck Hoberman, M.S., and Pierce Anderson, Lecturer in Design Engineering at the Harvard Graduate School of Design for designing folding mechanisms.

Brennan Phillips, a fellow of Wood lab and Assistant Professor of Ocean Engineering at the University of Rhode Island observed the model and suggested to use this device to catch the sea animals.
The device was identical to 3D printer polymer and joined with the series of rotating joints. Applying a little torque by the single motor to the point where petals meet, it leads to rotate the entire structure and makes a hollow dodecahedron. And hence, it is known as Rotary Actuated Dodecahedron (RAD). The team tested RAD at Mystic Aquarium in Mystic and collected and freed moon jellyfish underwater successfully.
