The Octopus and Soft Robotics BrightHub Education

<p>Octopuses are cool. Part of the Cephalopoda class suggested sef uh luh pod, that's any member of the phylum Mollusca, a small group of highly complex and arranged marine animals adding eight armed octopuses, ten armed squids, cuttlefishes, and the shelled chambered nautiluses. Octopus size is so varied it may be as massive as a school bus or as small as your finger. This sea creature has some stunning traits, right?It adapts to its surroundings in creative ways besides. </p>


<p>Do you recognize that if a predator bites off an octopus’ arm, the severed part will proceed to twitch and draw away the prey?But the best trick of all of them is that the arm will grow back. Yes, they can regrow their arms. The octopus can taste with its skin, and its eyelids, too. The hundreds of suckers on the enormous Pacific octopus, about 16,000 of them, can daintily pick up small gadgets by acting like a humans’ thumb and forefinger. If the item they pick up tastes good, well, they will pass it from sucker to sucker until it gets to the mouth—like a food conveyor belt. Octopuses also are masters of illusion and hiding. </p>


<p>Of the 250 species, its look may from time to time look fat and red, skinny and white, tall and brown—have stripes, splotches or become invisible. It can take a three foot long body and a melon sized head and squeeze itself via a hole the scale of a thimble. If that weren’t enough, he can free up a smokescreen of ink. If it finds itself in danger?The octopus can swim away quick by filling its mantle with water and blasting it out through a funnel tube giving them extra speed. This blastoff is referred to as, “jet propulsion. ”Biologists are interested by the intra arm conversation and the subtle intelligence of the octopuses’ appendages. </p>


<p>And for the not so squeamish, chefs in some Korean restaurants serve up those arms Korean style, “Sannakji”, which, to the uninitiated is live, raw, chopped up octopus arms served on lettuce with raw garlic, green onions and jalapenos and optional dipping sauces. The only challenge with this novelty dish is eating it: the arms will squiggle up to fifteen minutes after arrival for your plate and the suckers will not just attach themselves to the plate, they're going to grab onto your gums if you try to eat it. In the wild, octopus should be stealthy. How to flee a moray eel?How can I seize that spiny crab?What can Discover More Here pull out among that rock crevice?How can I stay safe when I have no shell?Some octopus have been filmed wearing coconut shell halves to use as transportable lairs; and that they can fold their bodies to fit inside the shells too. In captivity, it’s said they'll escape a marine tank, go next door to eat the other marine fish in a separate tank, and then return ignored. They can definitely unscrew the replenish a box. </p>


<p>A wily engineer once made some clear plastic cubes to keep the octopus entertained—as a result of they're smart and become bored easily. Each cube had a distinct latch with a tasty crab inside. The octopuses discovered slide bolts, a lever arm, and one eager octopus created a small hole to suck the treat out. Another just overwhelmed the box. Researchers were studying the octopuses’ arms own array of nerve cells dedicated to operating a little bit independently of the brain. Here is the scientist’s challenge. </p>


<p>Rigid laptop parts, the burden of batteries and the will for power have always been a stopper for highly computerized robotics. Harvard University researchers have just recently built Octobot using flexible elements. 3 d printing was used for the body, along with molding and soft lithography to create the flexibility of the arms. Basically, Octobot has no hard parts, no motor and doesn't perform with electricity, but instead, runs on pneumatic based gas pressure created from a hydrogen peroxide chemical reaction mix. The chemicals create a gas that when mixed together, fill the soft octopus arms and enable them to move!Another research target is concerning the fine movement of the cephalopod’s arm suckers, that are invariably accumulating data about their environment, both tactile and chemical, and might rotate and move for my part. Each sucker sensor has neurons for taste, chemoreceptors, for force, mechanoreceptors, and for place, position detectors. </p>


<p>Scientists are hoping to mimic and move some of these natural skills into synthetic intelligence robots in the near future. </p>
