<p><img class= Many 3D printing applications and innovations, such as self-folding objects, robots and face masks, were inspired by Japanese paper origami origami now has a collaborative group From Harvard University scientists, the University of Rhode Island and the City University of New York (CUNY), the principles of 3D printing and origami combined to find a less harmful way of capturing delicate, soft sea creatures like squid, anemones and Jellyfish.

While soft forms like these are adapted to the pressures of the oceans, it is difficult to catch them for study purposes, without violating the issues that people want to learn more about.The researchers involved in the development of the safety gear say these creatures are often referred to as "forgotten fauna" because their studies were so neglected, but the multi-university research team ste Recently released his 3D printed 12-page Trap in front of Rigami, which can gently fold around these animals without harming them.

The RAD device, which is short for rotationally actuated dodecahedra, is far more suitable for handling these sensitive animals than nets or aspirates. It can be attached to the arm of an underwater rover and then triggered remotely. He has already successfully caught jellyfish and small squids and octopi at a depth of 700 meters. However, the design can work in depths of up to 11 kilometers, with the possibility that it can be further enlarged for larger animals.

Zhi Ern Teoh, a mechanical engineer at Harvard, said the most important part of the design is to deploy it with just one engine, so the system has fewer defects. The team needed to create a complex set of poles that were light enough to not cause engine load but still be able to stay afloat, which would connect each of the 12 plates to the engine.

The RAD has some other important design touches, including the edges of the panels softer than the rest of the plastic fixture, so that creatures are struggling to get out (which saddens me to think about it, but I know it's important Studying animals so I can easily get over it) are not accidentally amputated. In addition, there are gaps between the individual plates, so that no pressure can build up when the RAD returns to the surface.

"I see this as a platform technology that we hope will continue to evolve – the dream is to enclose delicate deep-sea animals, take 3D images that include properties such as hardness to print the animal on the surface and to create a "toothbrush" that tickles the organism to get its full genome, then we would release it, "Gruber told the Verge.

The basic RAD organism can, as mentioned earlier, be increased for the capture of larger species, and Teoh even says that one day it might be possible to develop a version of human scale that could have self-building habitats in the home Space. In addition, the current remote-controlled RAD could in the future be turned into an automated trap that uses sensors to detect when a creature passes by.

3D printing has helped us to probe the seabed and remove debris from its shores, give coral reefs a helping hand and quietly observe marine life. Now, this basic 3D printed origami mechanism can help us to safely capture body with soft body for study purposes.

Gruber believes, and I agree, that this advanced technology is absolutely essential to exploring our oceans without causing further damage to the myriad of creatures that call them home. We only scratch the surface when it comes to finding out how important a role of marine life – from the smallest sea cucumber to the most massive coral reefs – can be in the entire ecosystem of the ocean.

The team published a publication about their evolution of RAD in the Science Robotics journal, which you can read here. Co-authors are Teoh, Brennan T. Phillips, Kaitlyn P. Becker, Griffin Whittredge, James C. Weaver, Chuck Hoberman, Gruber and Robert J. Wood.
