    scientists build artificial muscle that lifts one,000 times its own weight:

    Scientists at the Massachusetts Institute of Technology and university have developed a spread of origami-inspired artificial muscles which will raise up to k times their own weight — and nevertheless be dextrous enough to grip and lift a fragile flower.

    The devices, represented within the Proceedings of the National Academy of Sciences, supply a brand new thanks to provide soft robots super-strength, that might be used all over from within our bodies to space.

    Historically, robots are product of metal and alternative arduous materials as a result of it provides them strength. however robots conjointly got to be created out of sentimental, pliant components to agitate hard-to-reach places, navigate unpredictable environments and safely move with individuals. (Consider, as an example, the hazards of shaking hands with a golem with a steely grip.)

    So scientists have more and more tried to create robots with soft components. In earlier times, those bits were relegated to a tough robot’s outsides, primarily as artefact. however researchers ar Associate in Nursingd more} building golems whose alternative crucial components ar soft — recently going thus far on produce an octopus-inspired robot.

    “We’ve been fascinated by soft robots for a protracted time as a result of they’re safe, as a result of they're compliant and since they'll agitate uncertainty,” aforementioned roboticist Daniela Rus, director of MIT’s applied science and computer science Laboratory and one in all the study’s senior authors. “They’re terribly sturdy and straightforward to manage, comparatively speaking.”

    But there’s been one huge downside to soft-bodied bots: in contrast to robots created out of arduous materials, they’re not specifically power-lifters.

    “What we wish ar soft, safe, compliant robots that have strength, that have the properties that ar currently possible with hard-bodied systems,” Rus said. “This manner we've got the most effective of each worlds.”

    Rus and her colleagues solved this drawback by drawing upon artistic production techniques, that have recently evidenced helpful for creating several forms of robots. (One such larva, RoboBee, was pioneered by fellow senior author Henry M. Robert Wood of Harvard.) artistic production techniques have the potential to provide several complicated styles at low price as a result of they use little amounts of fabric and amazingly straightforward processes.

    For this work, the scientists used artistic production techniques to make muscle-like structures that might provides a limb flexibility however still permit it to maneuver while not having any arduous components.

    They designed plicate structures specifically meant to shorten, curl, twist or bend into specific shapes after they were compressed. The researchers sealed those long plicate structures in an exceedingly bag of compound “skin” and stuffed them with air or another fluid. once a vacuum sucked the fluid out, the artistic production structure squeezed along, contorting into the form determined by its folding patterns.

    The researchers found that some artistic production muscles might squeeze all the way down to a tenth of their original size, or raise up to k times their own weight. they may turn out roughly sixfold the maximum amount force per unit of space as class muscle.

    Each fold pattern will solely move in a technique, however Rus aforementioned many alternative patterns might be coupled along for a multifunctional golem, like associate degree artistic production Swiss Army knife.

    Such robotic limbs might be used at small scales, maybe to try to to repair work inside our bodies. they may be helpful at massive scales, for building in space. they may change wearable exoskeletons for lifting significant objects, or be sent to probe sea environments. they may even do the foremost deceivingly mundane tasks — like lifting a significant carton of milk or a bunch of grapes while not squashing them.

    A a lot of human-scale proof of construct might be next on the to-build list, the individual aforementioned.

    “I need to create associate degree elephant,” Rus aforementioned with fun. “Or perhaps a baby elephant.”
