Sorry, the squid: the robot can catch the fragile sea creatures, without causing harm
When scientists want to study fish and crustaceans, collect samples is simple: clear the network for the boat ride and accurately catch someone. But collect sensitive deep-sea organisms such as squid and jellyfish, is not so simple: the network can literally destroy the fragile creatures body. Mrs. Ern Theo, a mechanical engineer from Harvard mikrorobototehniki and his colleagues have developed a laboratory the best way to capture these elusive organisms.
What was it like before?
Now scientists who want to catch the delicate marine life, choose one of two ways (no, not the network). First, the sampler detritus, tubular device with round "doors" at both ends. To catch the creature with the help of this device, the operator must open the door manually position the tube over the creature, and then quickly close the door before the creature escapes. This positioning requires certain skills. The second type of device draws a sample through a tube into a basket for storage. This process can destroy the delicate creature.
as it offers to do now?
To create a device that is easy to use and will not harm the sample, Theo turned to the art of origami. He invented a device to the body of the 3D-printing photopolymer and modeled it in the form of a dodecahedron, figures with 12 identical plane faces. In an open state, it looks like a flattened starfish.
The device was tested at a depth of 700 meters, but it is able to withstand any pressure (even at a depth of 11 kilometers). Despite the large number of compounds, Theo device is opened or closed only movement using just one rotary power actuator. When the operator grasps the goal, the robot simply collapses and all the 12 facets form a cage for the creatures.
