News of high technology: the Terminator T-1000 is near

Almost every week in the world of high technology there is information about the achievements of the scientists in robotics. This week was no exception, but this time the news is a bit ominous.

Why with age, time flies faster than in childhood?

In the course of growing up-almost every person there is a feeling that over time greatly accelerated, it would seem that he only recently woke up and it was time to go to bed. For many years scientists tried to identify the cause of this phenomenon, and a new hypothesis put forward by researchers at Duke University, seems the most realistic. She says that the feeling of accelerated time due to changes in the aging brain, namely speed of information processing and the quantity of visual images.

Время и мозг

It was already known that changes in the sense of time related to the fact that an adult pays around events less attention due to the fact that they are already familiar — time is fast. Children, in turn, are interested all the events, and their brains process much more information — accordingly, the time seems to much slower flows.

A group of scientists led by Professor Adrian Bejana decided to dig a little deeper and found that children receive much more visual information than adults. They proved this by comparing the frequency of eye movements of people over the years. It turned out that children’s eyes “run” very often, and their young minds process large amounts of visual data, and very quickly.

Slow data processing in adults stems from the fact that plexus neurons in their brain are becoming more complicated and longer. Consequently, the signal takes longer than before. Thus, it may seem to people that their childhood up to 10 years lasted very long, while the adult life moves at lightning speed.

Robots are particles capable of much

Most robots perform tasks alone, but researchers from the institutions of Massachusetts, Harvard, Columbia and Cornell introduced the so-called “robot particle” that can only act in a team. Each of the tiny robots is a round mechanism that is able to connect with like by means of magnets. Working together, they can form a “swarm”, which takes a variety of forms, depending on the task. For example, the robots can move to the light source and push the items without problems passing through any of the passages.

The only movement that can make a “particles” is to compress and decompress in diameter from 15 to 23 inches. They use the built-in motor, batteries and a microcontroller that is responsible for the frequency of movements. To feel light source, each robot is equipped with a light sensor, and to contact the operator device for making teams.

Роботы-частицы

Single robot by itself is practically useless, but once they join the group — they can move and to move objects. The group can consist of an infinite number of devices and have any shape. For example, the accumulation may take an arcuate form and push the object, or lining up to pass through a narrow passage. Robots don’t rely on each other directly, so the broken one “particle” does not interfere with the movement and with the entire group.

The performance of a group of 24 robots have been proven in an experiment where they successfully moved the light source and pushed the subject. Computer simulations showed that the same efficiency has and a group of 10,000 robots — it continues to work, crap if 20% of the devices failed.

In the future, the researchers intend to simplify the design of robots and reduce their size. Thus they want to create a group of millions of “particles” that will be able to perform much complicated actions than now.

The postponement of the first flight of the spacecraft Boeing CST-100 Cockpit

The developer of the manned spacecraft CST-100 Cockpit Boeing has postponed its first test launch to the International space station (ISS) for three months. According to news Agency Reuters, referring to sources close to the project, at the same time shifted and manned test flight of the spacecraft with the crew.

According to earlier information, it was reported that originally scheduled for the month of March, the first test flight was postponed to the end of April. By this time the first flight of the ship with the crew at the time, was left unchanged — it was scheduled for August 27, 2019.

Now it became known that the first flight of CST-100 Cockpit unmanned, on 17 August. The same information is reported by the Russian news Agency RIA Novosti referring to a source in the Russian space industry with which the news of the postponement of the launch of shared American colleagues.

“The American side informed the Russian that the launch of an unmanned spacecraft Cockpit postponed to August 17 due to problems that occurred during ground tests of the ship”, — quotes words of the source news Agency.

The source also added that as a result of the postponement of the first test flight of the unmanned now also moved from August to a later date of start of the vehicle Cockpit to the ISS in manned mode.

Earlier also it became known who was to fly to the ISS in August. Aboard the CST-100 Cockpit will be a crew of NASA astronauts Michael Fincke and Nicole Aunapu Mann, and also the astronaut of the Boeing company Christopher Ferguson.

With the closing of the space Shuttle program the US has not been able to deliver their astronauts to the ISS and bring them back. To do this, America used the services of Roscosmos and the Russian ships “Union”. New ships for manned flights under contracts with NASA, has developed a private American company SpaceX and Boeing. The first test launch of the new ship’s Crew Dragon from SpaceX to the ISS on 2 March. The flight was unmanned. When you are docked automatically with the ISS a day later, the machine was in orbit for 6 days, after which the March 8 returned to Earth, descending on parachutes and provodnitsas in the Atlantic ocean. According to current plans, in July to be held the second test launch Crew Dragon, but with a crew on Board. The first to go to the ISS on a private spacecraft will be astronauts-veterans of NASA, Bob Behnken and Doug Hurley. After that, NASA needs to make a decision on the certification of Crew Dragon for regular flights.

For insurance in case of unavailability of spacecraft SpaceX and Boeing, space Agency NASA declared the desire to get some more seats on the Russian Soyuz in the period from 2019 to 2020-th years. A few days earlier the head of Roscosmos, Dmitry Rogozin on his page on “Twitter” confirmed the readiness of Rocksome to help American partners on this issue.

Scientists closer to creating liquid “Terminator”

Certainly, when watching the movie “Terminator 2: judgment day” and almost every spectator was delighted with the cyborg T-1000 liquid metal. At the moment the creation of such a robot, of course, impossible, but scientists are slowly moving towards this goal. For example, researchers from the American chemical community has managed to create liquid metal that can be manipulated using a magnetic field. This can be considered a small but important step, because this is the first case when the material is managed to move not only horizontally, but also vertically.

If in the future will be created and liquid robots, then surely they will be made of gallium or other metals that melt at room temperature. In addition to this property, they have other features like high conductivity and infinite flexibility. Liquid metal can be moved by means of magnets, but be sure that the alloy was added particles of Nickel or iron.

Unfortunately, due to the high surface tension of magnetized liquid metal can move only horizontally and only within a liquid. But researchers have found a way to move them even vertically. They reduced the tension, creating a liquid alloy of gallium, iron, indium, and tin — immersion in hydrochloric acid on the material surface was formed a layer of gallium oxide, which affected the surface tension.

Attaching a magnet to the opposite sides, the researchers ensured that the material was stretched vertically. This means that they can be moved even in three-dimensional space, not only in the plane as before. The new alloy is not yet ready for use in liquid robots, scientists are still far. However, a new discovery, but has brought scientists to the creation of a new kind of robots.

As you see, the year in which humanity will create a liquid robot? Impressed if you cyborg T-1000 from the second “Terminator”? My assumption is the answer is possible to write in the comments or in our Telegram chat.
