crabs. i asked for a story about crabs. this is st ives. snorkellers, these pictures have been taken by snorkellers. these crabs, pincer crabs, spider crabs, sorry, they have long pincer claws that get up to eight inches, and so at st ives, i can t print out this, and i apologise if i get this wrong. what wouldn t beach ginseng dies. they go there to shed the exoskeletons, and so the reason they come in, they come into the showers waters because they are really vulnerable at that point because they shall come off and they need to reform, so they all come into the showers waters and lots of tourists were screaming about it. but some divers took these pictures. it is fabulous! bike out of a documentary. and all of the shells are floating to the surface, just kind of being left there, really good! some people may have seen this already. this is a picture of a baby
Shape memory alloy (SMA) wires are one of the widely used materials for soft artificial muscles. However, SMA artificial muscles have two problems, including limited load holding ability due to their soft nature and slow response due to their long cooling time. The main contributions of this article are the developments of a controllable magnetorheological fluid (MRF) exoskeleton and a fast-response magnetorheological elastomer-SMA artificial muscle as effective approaches to solve the above-mentioned problems. The controllable MRF exoskeleton provides variable stiffness so that it can be flexible enough to allow the manipulator to bend as required while stiff enough to hold up heavy loads. This new artificial muscle accelerates the cooling speed of SMA wire to shorten its recovery time. Our tests proved that this new artificial muscle, compared with conventional SMA artificial muscles, could improve the recovery speed by up to 333%. The new artificial muscle and the MRF exoskeleton as
Over the last few decades, scientific innovation has amplified our human desire for inventions and gadgets that can take us to new heights. From the workplace to our homes, tech and advanced software have made our lives easier in nearly every aspect - and now a few companies are bringing exoskeletons to the mainstream tech market.
