In order to present a white and translucent skin tone that conforms to the oriental aesthetics, the bionic skin of the humanoid robot is not directly filled with a good color, but adopts a multi-layer structure similar to human skin, and uses soft materials of different materials with different transparency and color to simulate the transparent epidermis, high-elastic dermis and subcutaneous tissue of human skin respectively.

At a cursory glance, the inside of the bionic skin is red, but if you look closely, you will find that it is actually a dense red device on a white base, and almost all parts are made of red.

In this way, when the light passes through the translucent bionic skin layer, the red light reflected back by the red "skin" at the bottom layer will be refracted by the dermis layer and finally become a faint human skin tone.

In fact, there is no such thing as pink light in nature, which is an "illusion" unique to the human eye, just as we would see seven colors of light as white light.

This skin tone, which allows the red base layer to pass through the white translucent medium, looks more textured and realistic than spraying paint directly on the surface of the bionic skin, without the inconsistent rubber luster that is unique to ordinary plastic robots.

For robotics that pursues flying over the Uncanny Valley, the fidelity is never-ending, and only by getting as close to 100% realism as possible can we avoid falling into the uncanny valley trap and causing consumers to feel bad, so even if the cost of using multiple layers of skin has increased significantly, it has to be chosen.

The effect of this bionic multi-layer skin is indeed worthy of the complex production process and high cost, the previous generations of bionic robots can also let people see the traces of "fake" people, but the current Xiaoxing series is completely invisible, whether it is the existing picture recognition engine or many netizens, they can not see the fake of Xiaoxing at all; Nowadays, at least looking at photos and videos over the Internet, and actually viewing them at medium and long distances, it is impossible to distinguish between real and fake.

Only when you look closer, by observing the abnormal movement of the muscles, and the skin with only pores but no hair, can you see that Xiaoxing is not a real person; Of course, this is also something that can only be seen by someone who has this kind of observation.

This is also something that can't be helped, although Xiaoxing uses a large number of micro motors to simulate the stretching effect of skeletal muscles, which can better simulate human limb movements than traditional rotor motors.

However, there are more than 600 skeletal muscles on the human body, as well as an uncountable number of muscle fibers to form expression muscles, etc., with the existing technology, it is impossible to completely restore 100%, so we can only choose the best, and give priority to the selection of obvious visual effects and less difficult simulation for simulation and realization.

Now the focus on the flexibility of the limbs, so that robots can replace humans in work, the current generation of robots, in the dexterity of fingers, even more than most ordinary people.

In Xiaoxing's "abdominal cavity", there are no wires, gears, and geometric shapes that people have in the impression that the robot torso should have, and the edges and corners are full of various parts of mechanical beauty.

In addition to micro motors, wireless charging technology is also used on a large scale, and most of the motors in the whole body are driven by a series of wireless energy transmission and micro energy combinations, and the whole body is filled with micro energy that can only work for micro motors for a few minutes, and then the whole body is transmitted wireless energy through a large reserve energy group in the abdominal cavity.

The overall power system is composed of a carbon fiber skeleton and more than 200 micro linear motors and micro hydraulic transmissions, while there are no mechanical parts in the abdominal cavity, mainly a large string of batteries and overall control modules.

In addition, there is a computer system that acts as Xiaoxing's brain, as for her cranial cavity, there is no "brain" for thinking, and the overall facial system and visual and auditory collection system that simulate the expression muscles take up too much space, resulting in insufficient available space in the cranial cavity, plus the problem of heat dissipation is also considered, so the computing module is all moved to the chest cavity, almost in the heart area.

As a robot, Xiaoxing, which uses a battery to drive the motor and drive the movement of the limbs, needs to consider the problem of heat dissipation, so there is a complete set of simulated vascular systems to form a complete set of water cooling and heat dissipation systems.

However, unlike the general water-cooled heat dissipation system, where the cooling water circulates in a closed pipe, the heat dissipation system on Xiaoxing's body is semi-open, on the one hand, there are heat sources that flow from the heart through joints, drive motors, wireless energy transmission components and other heat sources to take away the heat, and then flow into the whole body heat dissipation network, and finally flow back to the complete circulation of the heart; On the other hand, artificial skin is porous and will "leak", and every time the cooling water flows through the skin, there will be a small amount of loss, and this part of the water will be lost under the action of water surface tension and water pressure, along the small sweat duct structure connected to the capillaries in the artificial skin, "crawling" to the surface of the skin, becoming sweat and finally evaporating into the air.

The reason for this design is also determined by Xiaoxing's extreme pursuit of realism to human beings, and simulating human beings naturally cannot be less than 37 degrees Celsius human body temperature.

This water-cooled system flows into the computer module and the linear motor module that simulates the skeletal muscle, bringing its heat to all parts of the body, which not only avoids the danger of overheating and burning of the computer module and the motor, but also achieves the waste utilization to make the surface of the small star heat close to the human body.

However, relying solely on the skin surface to dissipate heat, when encountering high room temperature, thick clothing, strenuous exercise, excessive use of the brain, etc., it may cause the body surface temperature to exceed 36 degrees Celsius and cause fever.

Therefore, in order to avoid "fever and illness", the system will increase the rate of heart rate, increase the pressure of the water circulation system, promote "sweating", and thus rely on hot water evaporation to lower the body temperature.

In order to prevent the precipitation of dissolved substances in the water from being adsorbed and clogging in the heat dissipation pores, the bionic robot can only use a special reddish "heat dissipation water", which will store part of the "heat dissipation water" in the body and automatically replenish the water consumed by the skin according to the blood vessel water pressure through the circulatory system.

There are also several micro-cooling tissues inside the body, which maintain the water temperature, and the superheated water will be dispersed to the surface and discharged, and this overall heat dissipation circulation system has taken dozens of researchers more than half a year.

"I believe that it won't be long before this team can achieve good results, at least it will definitely be better than the men's team."

If it is said that in the past, yellow people were not as good as whites and blacks because of their physical strength and overall physical fitness, resulting in poor football performance.

This can be a reason, although in this reason, there are also strong teams in Asia, such as Dongying and Thailand, as well as Chen Guo, a football powerhouse.

Saying this, it is naturally Yang Yi, the Archon of Sulawesi, the President of Star Group, and the Chairman of Shanghai Star Women's Football Club, who has just changed his outfit and incarnated as a young man of Sunshine and Vitality Sports.

However, today, the Shanghai women's football team is specifically mentioned, because of today's exhibition match, so Yang Yi only appeared on the sidelines of the sports field today, watching a unique game with countless media and audiences.

This is a football exhibition match, the two sides are the Star AI football team and the Shanghai women's football team, in the last Women's World Cup, the Shanghai women's football team finally participated in the competition, and won the championship trophy.

The performance of the women's football team is in stark contrast to the men's football team, even if all the members of the men's football team have become "new humans", it can be said that there is no physical difference between white and black people who have also become "new humans", but the results are still very poor.

In the group stage, it has lost to Dongying, Thailand, and Brunei, which is disappointing enough, and the eyes have turned to the women's football team.

Since this year, all international sports events have begun to change the rules, because most of the evolution of human beings has led to the explosion of all the results of major sports.

The resulting changes to sports such as football, basketball, rugby, baseball, etc., are still being discussed.

This exhibition match is also a trial, before that, the Star AI Little Star Team has already played exhibition matches with several teams, such as some teams in the men's football second division and the first division, basically won, and now it is to start challenging the first team in China - Shanghai Star Women's Football Team.

After challenging and clearing Go, table tennis and other sports, the robot once again set its sights on football, the world's largest sport.

In general, up to now, Yang Yineng said that the little stars have not embarrassed her, there is no mismatch between left and right power, becoming high and low feet and short legs, running and running to draw circles and even fall to the ground to eat grass and mud, and there is no lack of power, unable to kick the ball but falling down, but in addition, at the beginning, the situation on the court was still a little chaotic, and all kinds of strange events kept appearing.

The Xiaoxing robots on the field are the latest generation of products, and the overall height is basically between 170-175, the weight is about 50 kilograms, and the overall cost of each unit is about one million.

Speaking of which, this form of robot, although it seems to be able to sing and dance now, light body, and developed movement, but its power system redundancy is very small, the clothes on the body are slightly thicker, the action strength is a little larger, and the dance and some movements can not go on, and the dance performed in front of the camera on the stage, the movements are specially designed, and the postures that are too intense and consume too much energy have been deleted, so that there can be a good dance effect.

If there are really users who spend a lot of money to buy "them" home, the well-packaged image of "dancing elves" will be immediately exposed.

This is also the reason why although the starry sky is promoted on a large scale, but it is not promoted to the personal market, in the final analysis, this kind of robot technology is not practical enough for the time being, and it is not suitable for the civilian market at all.

Now it is mainly facing the commercial market, such as team sparring, at least now after dozens of exhibition matches, football skills are already very strong.

At the beginning of the football exhibition game, the game was not good-looking, the scene looked noisy, the performance of the robot players on the field can be said to be super bad, the pass is big, the shot is not powerful, and the stop ball is snatched away are the norm, and from time to time because of the scrum and crash together, people fall on their backs, turning football into rugby.

The most commendable thing is the goalkeeper of the AI team, who is almost foolproof in his defensive skills.

Although the AI goalkeeper doesn't do much of those psychedelic actions, the opposing striker has a probability of not being able to score more than eighty percent, either the strength is too high, the shot is too high, or the strength is too small and passes directly into the goalkeeper's arms.

However, in the setting, the AI goalkeeper relies on strong computing power to quickly determine whether the opponent's shot can be kicked and defended.

If you can kick in, you will also do some psychedelic actions, starting from the team of A and B, playing all over the teams, at the beginning, there will be some draws, because neither side scored, the AI side is because of the strong defensive ability, there is a strong goalkeeper, but the offensive ability is not good.

But later, with the increase of experience, the AI that has been learned has grown rapidly, and in the exhibition match with the first-class team, it has won its heyday, and this time the match with the strongest team of the women's football team is the last one in China, attracting many fans to participate.

Xiaoxing series has built a total of more than 70 units, minus 48 defective units, the overall cost of materials is more than 100 million, and the research and development cost is more than 100 times, although many of these technologies can be used in other projects, but Xiaoxing series also has to be promoted, in order to carry out the next generation of research and development.

At present, Dongying people have bought two, one for Go and one for table tennis training; Chen Guo also bought two units, which were used for the same purpose as Dongying; Most of the other countries bought only one for research.

Now, with small profits and quick turnover, one only sells for 2 million, there are still 37 units left, which needs to be further promoted, and it is naturally the most cost-effective to sell to football projects.

Football is a game that requires 11 people, and each football club is a local tyrant, and buying 11 AI players as sparring partners is only 22 million, which is not as good as the transfer fee of a good player.

This market is very large, at least there are more than 10 teams that can afford it, football can, then basketball, rugby will naturally have teams to buy.

In this way, the R&D cost can be recovered; Originally, Yang Yi was thinking about developing in the film and television industry, and AI robots are very useful for film and television drama shooting, and martial arts actions that are not afraid of casualties are a good way to use.

It's just that now many film and television production companies are taking resources to support people, and the promotion in this regard is not going well, so after thinking about it, they will be used as "Dancing Queen" performance guests.

This time, I was going to invite a girl group to come, but the asking price was too high, so after thinking about it, I arranged the dance moves and asked the "little stars" to be the performers.

This has also caused a big crisis, and some people have begun to take the rhythm in the media, such as "the human rights of robots", "robot threat theory" and so on.
