Zhi Ern Teoh, a former Wyss Postdoctoral Fellow, got the idea to apply folding properties to underwater sample collection in 2014. These deep-sea organisms, some being thousands of years old, deserve to be treated with a similar gentleness when we're interacting with them." “Would we cut pieces out of the Mona Lisa to study it? No - we'd use the most innovative tools available. "We approach these animals as if they are works of art,” said David Gruber, Presidential Professor of Biology and Environmental Science at Baruch College and co-author of the study. The structure rotates at its joints and folds up into a hollow dodecahedron when a single motor applies a torque at the petals’ meeting point. The device, described in Science Robotics, consists of five identical 3D-printed polymer "petals" that are attached to a series of rotating joints that link together to form a scaffold. It is designed for midwater interaction using rotary-actuated folding polyhedrons to quickly and safely capture marine organisms such as jellyfish and octopuses. RAD (rotary actuated dodecahedron), was developed by a team from Harvard University’s Wyss Institute for Biologically Inspired Engineering, John A Paulson School of Engineering and Applied Sciences (SEAS), Radcliffe Institute for Advanced Study, and the City University of New York's Baruch College. The rotary actuated dodecahedron (RAD) sampler has five origami-inspired "petals" arranged around a central point that fold up to safely capture marine organisms, like this jellyfish (Credit: Wyss Institute at Harvard University)
