One of the main problems – hands starts shaking involuntarily, which adversely affects the accuracy. How can I fix the problem? Either classical methods or by using MAXFAS.

Efficiency in the exoskeleton technology

Under this acronym hides a new prototype exoskeleton technology for the military. The invention automatically “stabilizes” movement of the wearer, increasing the efficiency of the fire.

Full name of the initiative – Mobile Arm eXosceleton for Firearm Aim Stabilization. Develops system Research Center of the US Army soldier’s outfit.

How does the new product? On the shoulders and wrists arrow mounted servos, cables, as well as various sensors. Built-in computer records and dampens unwanted vibrations promotional tremor.

If you believe the engineers said can increase accuracy by 27% (on average). Simply put on the exoskeleton technology.

That’s great – the product is relatively easy. The creators are going to achieve weight 300 grams. At the core of carbon fiber. Another important detail: MAXFAS not prevent deliberate action does not confuse them with the accidental.

Alas, the introduction is too early to say. The new project exoskeleton technology is brought to mind. The date of “release” of information there.

Walking is a good form of exercise. But there are some cases where a person may need additional assistance during walking. For example, patients who have had a stroke, or a person who, on the contrary, spending too much time on their feet.

For the first time, experts can improve walking person without the use of an external power supply, according to a study published recently in Nature. The Exoskeleton, which is placed in an ordinary sneaker, reduces energy costs of human walking about 7 percent, which is equivalent to the fact that you will remove the 4.5 pound backpack. The device makes walking less tiring. Researchers at Carnegie Mellon University and the University of North Carolina using elastic exoskeleton.

However, 7 percent reduction in energy expenditure during walking is not a completely new development: the researchers achieved similar success in the past. In 2013, a group of researchers has achieved a 6-percent reduction in energy consumption due to the compressed air system. Others worked with the exoskeleton is powered by electric motors and batteries.

Unlike most of the calf muscle is not “turned on” by reducing and compressing itself. This provides a rigid connection in which the Achilles’s tendon can be stretched. With each step, the passive coupling activates a spring disposed parallel to the Achilles’s tendon, taking the load off the calf muscles. The device has a super light weight. This means that the wearing of such a mechanism does not require additional costs. “The device weighs 300 to 500 grams, which is slightly heavier than your sneakers,” – say the creators.

Specified. that the device has been tested on nine able-bodied adults. I wonder how the device is used in everyday life. “It is not clear how the device will not respond rhythmic cyclic tasks,” – said Daniel Ferris, a biomedical engineer at the University of Michigan. “Use the invention is not very difficult,” – said Sawicki, co-author of the research. “After 20 minutes, most people do not notice it and remembered only when it is removed.”

When it comes to the exoskeleton, just seems solid construction. Robotic, with a bunch of heavy batteries, full pneumatic and electric motors.

As it turns out – this is not the right approach. A group of researchers managed to produce a “soft” analog. The prototype is called Sensorimotor

Of course, the invention is not superhuman talents grants. To transfer the goods in hundreds of pounds more suitable “rigid” model (like the XOS 2, Fortis or HULC). Exoskeleton of flexible materials intended for other purposes. It improves sensorimotor function by reducing the load on the muscles of the upper extremities.

Owner’s life literally becomes easier.

SEnS designed by Japanese experts Hiroshima University (in collaboration with colleagues from other institutions and companies). Do you have news commercial prospects? Any more.

So easy and unobtrusive “suit” is useful to all who work in extreme conditions. Yes, and the elderly extra power does not interfere.

The Agency for Defense Advanced Research Projects USA (DARPA) has officially stated that it is ready to proceed to the second phase of the program Warrior Web, aimed mainly at the soldiers.

According to DARPA, the soldiers in the infantry missions often carry electronics, supplies, weapons, and other cargo weighing up to 50 kg. In overcoming long distances extra weight increases the risk of injuries of the musculoskeletal system in such sensitive areas as the knees, ankles, hips and lower back. 

Over the past few years in the web quite often there are news about the development of special exoskeleton, which reduce the power of exercise on the soldiers, but they tend to turn out to be quite practical. In contrast to the large number of cumbersome exoskeletons Warrior Web suit is so easy and convenient, it can be worn under normal uniforms.

In the current prototype suit implemented technologies that enhance the power of the joints, the weight is distributed throughout the body and provide a kinesthetic sensations (feelings position of different parts of the body and the muscle forces produced during the movement). In the configuration of the costume also includes a plurality of sensors designed for diagnosing a soldier in order to increase his endurance missions.

The so-called phase “B” implies a search for ideas for improvement and commercialization. Special event for interested parties will be held on September 5. Currently, DARPA is looking for ways to improve existing technologies and examines the materials and fabrics that will suit the most convenient and invulnerable. The Agency is also interested in the opinion of experts on the question of the potential use of costume in physiotherapy and rehabilitation for people with limited mobility.

At the moment, there are three laboratories DARPA working prototype Warior Web, but the agency hopes that this year will focus on one of them.
