The new exoskeleton can afford to run 7 times faster than usual
Source:
The Ability to run fast can be useful in a variety of spheres, no matter if you are a professional sport or just want to get to the rack with buckwheat in the store, way ahead of all its competitors. For those and for others, experts from the Vanderbilt University in the USA came up with a unique new device that allows you to run at a speed 7 times faster than normal. It is known that when used correctly, the mechanism is able to bring the running speed of a human for cycle indicators, amounting to approximately of 20.9 meters per second.
How to run fast?
A Unique exoskeleton that can give anyone the speed of the Bicycle is a system, the principle of which is very similar to the catapult. A special spring mechanism, which became the basis of unusual devices, can provide incomparable support to people experiencing problems with the lower extremities. And although currently, the exoskeleton is still in the testing stage, the developers claim that their prototype will be ready by next year.
The Result of our work may lead to the creation of a new generation of devices specially designed not only for rescue operations and improve the work of law enforcement agencies, but also for those areas where people could benefit from increasing the speed of movement — the researchers write in their published article.
The mechanism of operation is based on the principle of a conventional Bicycle, the pedals which help us to promote themselves forward as the movement, writes . However, making the feet move up and down, the person doing the Cycling, did not even realize that thus loses a lot of potentially productive time that is wasted at the moment of pressing on the pedal.
So how best to use this «lost» time? The researchers behind it , considered the various concepts by conducting experiments on spring fastener, which is similar to a catapult. According to their theory, the feet are able to perform useful work even in quiet state, and to achieve a similar effect can help a special pair of springs attached to the legs. However, while this idea exists already for more than a century, in itself it is not particularly effective. In order to improve the previously inefficient technology and check how it distributes energy from the change of the spring, the researchers decided to model the prototype device on the computer.
the mechanism of the exoskeleton works with the help of special springs
So, according to extended in the course of the experiment assumptions, effective work of scientists created the device will occur from the bending of the legs and forward motion in the air. Giving the body additional support, the spring can release that energy upon contact with the ground, helping the person to develop good extra speed. The analysis shows that for maximum speed the spring would have to capture the energy from each step at 96 percent, while simultaneously passing all the received acceleration. If so, the figure of 20.9 meters per second — the maximum speed when using the “boots-walkers” twenty-first century — also based on the energy generated by the cyclist of world class. In other words, for most of the population of the planet speed when you apply the device might be a bit lower than claimed.
Currently, the researchers have still many problems associated with . Anyway, experts are optimistic and intend to adapt the work of the spring to different speeds, as do gears on a bike. And, who knows, maybe a new technology could one day fit in conventional shoes, thereby creating the preconditions of their use not only in extreme situations, but when creating a completely new sports.
