MIT Synthesizes Nylon Strings into Muscle

Researchers have been trying to build long-lasting, low-cost synthetic muscles for years, but to no avail. The systems developed to date have either been too expensive to produce (such as carbon nanotubes) or too delicate and power-consuming (such as memory alloys) to be useful outside of laboratory conditions. But MIT team just synthesized muscles with nylon fibers.
The advanced materials reported are how the fibers are shaped and heated. Nylon fibers, when you heat them, they grow, but the diameter expands this weird natural property. This makes them ideal for straight-line movements, like lifting weights. But bend nylon, because it shrinks is not so simple.

Normally, nylon bends are obtained, which adds weight, complexity, and cost to the system. To avoid the three exact things in creating a mass-produced technology. However, the MIT research team came up with a clever solution. Using normal nylon filaments, first compress it to change the cross section of the fiber from a circle to a square. Then they are heated on only one side of the fiber, making it shrink faster than the unheated side forces the entire chain to bend.
This breakthrough can be applied in a variety of industrial and commercial applications. Powered clothes will automatically shrink to the exact shape, which means that everything in your rack is in your size. These fibers can also be used in cars and airplanes.
The technology can even lend its own self-regulating catheter insulin pump. And in the end, we can even see them in robotic bionic muscles.

Actually, a wiper assembly that refuses to move might have a simple blown fuse. But usually fuses don't blow on their own. Even at full stall, the current draw of the motor should be well below the fuse's rating. If the fuse is blown, odds are there's something else wrong, like a shorted wiper-motor armature or faulty wiring anywhere along the harness between the motor and the switch. Even a mechanical problem like a seized bushing can make a fuse eventually fail.

The fuse is okay, or you've replaced it with one that has the appropriate amp rating. There's still no action? With the wipers and ignition on, whack the motor assembly with the handle of a screwdriver or a rubber mallet. If that gets things moving, you've got a bad commutator or an open winding on the armature. When the motor parks, if the brushes are sitting on the bad segment, no current flows. Whacking the whole business smartly can sometimes jolt things into motion. Because there are often a dozen windings on the armature, the motor runs fine until the next time it comes to rest on the bad spot.
