To call someone “spineless” is an insult on land, but in the ocean, it’s simply a sensible lifestyle choice. From jellyfish to octopuses, anemones to sea cucumbers, life under the waves teems with squishy invertebrates. But while these soft bodies are perfectly adapted to the crushing pressures of the ocean, they present a problem for scientists who are hoping to study them. How do you retrieve such delicate organisms without damage?
One answer might lie in the Japanese art of origami. Inspired by the traditional paper-folding techniques, engineers and marine biologists have designed a 3D-printed, 12-sided origami trap that can fold gently around unsuspecting sea creatures. The device (known as the rotary actuated dodecahedron, or RAD for short) can be attached to the arm of an underwater rover and triggered remotely to capture soft marine life safely.
The device has already been tested successfully, trapping small squid, octopuses, and jellyfish at a depth of 700 meters in the ocean. But its design is robust enough to work at depths of up to 11 kilometers, and it could easily be scaled up to target larger organisms.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
