The Rotary Actuated Dodecahedron Safely Captures and Releases

The Rotary Actuated Dodecahedron is a 12-sided contraption robot designed to gently capture sea creatures without damaging them. The underwater robot's design draws inspiration from traditional Japanese paper-folding techniques and it is constructed using 3D printing processes. It can be attached to the arm of rovers and controlled above water to capture the delicate underwater organisms. It was developed by Wyss Institute for Harvard University, providing them with a non-invasive tool for extracting marine samples.

The Rotary Actuated Dodecahedron is comprised of five 3D-printed parts of polymer petals that are connected to a range of rotating joints controlled by one motor. It rotated to fold up into a 12-sided cage construction and dives as deep as 700 meters. It has so far captured and released marine organisms including octopus, jellyfish and squid.
