Technology and life: starting with solar cars

Chapter 25 Appearance of Silicone Skin
After a few hours, Liu Yun felt that Liu Jinwei should have finished designing the program.

So he interrupted Liu Jinwei, who was feeding, and said, "Have you two finished designing?"

"After the design is finished, there is a counter next to the circuit board, which will count the number of times except for the thumb. Every time the cumulative number reaches 3, it will be reset. When the tendons in the arm move, the first joint bends to 45 degrees, and the second The joint bends to the level, completely imitating the bending mode of the human finger. When the tendon moves again, the mechanical finger will bend to the extent that it touches the palm. The tendon moves again, and the finger is fully stretched. If you are not satisfied, you can do more Set a few fingers to bend." Liu Jinwei put down the bowl in his hand and said.

He really spent a lot of effort on the design this time, and even made several preparatory plans, just to make Song Fangqing wear a prosthetic limb that would look a little more like a real finger.

"Don't make the design so complicated at the beginning, just like a child learning a bicycle, learn the simplest one at the beginning, and then design more complex modes after getting familiar with and mastering the simplest control mode, I guess next time I will design the fingers Bending mode Song Fangqing's fingers should be able to move freely like ordinary people without any feeling of stiffness." Liu Yun felt that Liu Jinwei might be stupid, Song Fangqing hadn't adapted to it yet, and wanted to give someone a complex finger pattern.

"Okay, let's make the design simpler this time. Next time, I will design it with 10 finger positions. At that time, as long as you practice proficiently, it will really be like your own fingers. It is the same as typing. It was very slow at first, but once you get used to it, you can quickly type it out without looking at the keyboard." Liu Jinwei also knew that he was a little impatient, mainly because the injured person was his dream lover who was suddenly dazzled by love.

Liu Yun didn't speak any more, picked up Liu Jinwei's code and looked at it, after getting along for such a period of time, he can somewhat understand some simple computer languages, such as int string char these simple things represent everything has been figured out.

But having said that, learning code is really boring and boring. Those code masters are not generally good, at least the mood is very good.

Regardless of the operation aspect, at least the design aspect is almost completed, Liu Yun said with a sigh of relief, "The last item of design is left, and that is the production of inflatable human bionic skin."

"Haha, brother, do you want to say something inflated? You are so shameless." An Cui made a face at Liu Yun.

Liu Yun's words almost made her laugh to death. Do you really think she is a child? She knows what it is just by saying the word inflatable.

"Cut, Liu Yun, you are really shameless. Talking about those unhealthy things in front of so many people is not ashamed. Why did I agree to work under your hands? I don’t like luxury toilets anymore, it’s a pit.” Deng Yunqi was also a little unhappy, discussing in front of her, a lady, whether those unhealthy things are really good.

And Liu Jinwei smiled awkwardly, thinking of some inflatable past.

However, Wang Chuanjun didn't respond to this. He was originally a great god who reached the pinnacle of life early and saw through the world of mortals. He didn't seem to have much demand for that.

"What are you thinking? The inflatable thing I'm talking about wants to restore the skin of the human body as much as possible. To be honest, the color numbers of the human bionic skin sold online are too different from the human body. As long as you are not blind, you can see it at a glance. The skins that come out are fake, I really don’t know why those people on the Internet would buy these things.”

Liu Yun changed the subject and continued: "Besides, there are two beauties, do I need that thing?"

"What did you say? You bastard Liu Yun, believe it or not, I'll tell my aunt?" An Cui angrily stepped forward and twisted Liu Yun's waist, which was very painful.

Not to be outdone, Deng Yunqi picked up the notepad and threw it in Liu Yun's face. She had a more docile personality and did not do those extreme behaviors.

Liu Yun was in so much pain that he said to Wang Chuanjun next to him, "Old Wang, see if you want to give one of these two beauties to you. How about my sister An Cui? Do you want it? I think you two are a good match. A fool and a nerd are a match made in heaven, that's quite suitable."

Liu Jinwei nodded, Deng Yunqi nodded, and even Song Fangqing nodded. Except for the two involved, everyone felt that An Cui and Wang Chuanjun were a good match.

Wang Chuanjun hesitated and said: "I have no plans to start a family yet, but I do have plans to become a monk. Maybe I will become a monk sometime, because I think I have already seen through the world of mortals."

"Slap." Liu Yun slapped Wang Chuanjun mercilessly. The slap with all his strength was extremely painful.

Wang Chuanjun didn't know what was wrong with Liu Yun, but it didn't stop him from getting angry. He stood up angrily and asked Liu Yun, "What do you mean? Why did you hit me?"

"Didn't you say that you see through the world of mortals, so I will try to slap you. Look at your angry look now, it shows that you have not seen through the world of mortals. I think it is the king's benefactor, you are pretending, and you are not suitable to be a monk. , let’s stay in the world of mortals honestly.” Liu Yun rubbed his numb palms and said.

Beating Wang Chuanjun actually felt a kind of pleasure, is this the feeling of beating the Son of Destiny?

After arguing for a while, it was time to get down to business. Liu Yun waited for everyone to calm down and said: "The design of this skin looks the simplest, and it is indeed the simplest item, but it is just a simple technology. There are many procedures, and it is very simple. Trouble. Because my request is not to make those junk products on the market, what I want to make is a silicone skin that is 90% similar to a human hand. Pores, wrinkles, creases, and nails must all be present. The size is 1 :1 At the same time, every detail must be in place.”

"Liu Yun, do you want to design this silicone leather cover on the robotic arm?" An Cui asked blankly.

"Aren't you talking nonsense, I designed a silicone skin and don't put it on the mechanical arm, can't I wear it myself? I'm sick."

"You are indeed a little abnormal." Deng Yunqi actually cooperated with An Cui to speak.

Liu Yun was stunned, what is the situation, when did these two women get so good.

As everyone knows, Deng Yunqi and An Cui watch and discuss TV dramas together all day long, and gradually become best friends, but Liu Yun, a sloppy eye, doesn't know it at all.

The main reason is that Liu Yun usually doesn't pay much attention to these things. He also has things to do when he is free. Can't he play games or something, or how boring he is when he is free.

"Next, let me start with the key points. Let's start with the nails on the palm of your hand. You women are familiar with nails. Is it better to use ceramic, plastic or metal for your nails?" Liu Yun is really unsure about this.

Metal is the most durable. There is no doubt that the degree of simulation of metal is too low. It is easy for others to see the authenticity. Ceramic is more suitable, but the material of ceramic is a bit brittle, and it may break, which would be embarrassing.

Plastic is definitely not easy to break, because it can be transparent and has a high degree of simulation, but after a long time of use, there will be a lot of scratches on the plastic, and the scratches will become more and more fake as time goes by. , so Liu Yun was very entangled.

"I think it's better to use plastic. The plastic is light. When the time comes, you can do a manicure on your fingernails. Just use the manicure to cover the scratches on it." An Cui suggested.

Everyone nodded, thinking that this suggestion is really good. It is a good idea to use plastic ones for manicures so that the abnormalities of the nails will not be visible at all.

"An Cui's proposal is good. Does anyone have any suggestions? Both men and women can talk about it. Since it's a discussion, let's express our opinions. Don't be afraid to make a mistake and be ashamed. Let's discuss and make progress together." Liu Yun looked around, wanting to encourage The rest spoke up enthusiastically.

"I think it's okay to use ceramics. If you use ceramics, you can put the fingernails on the palm of the robot. Don't inlay them on the silicone skin. The inlays on the silicone skin are easy to fall off. It's better to fix them on the mechanical fingers. position, then you can replace the nail cap at will, and you are not afraid of the problem that the nails are easy to fall off on the silicone.” Deng Yunqi also has his own suggestions.

The crowd nodded again, thinking that Deng Yunqi's suggestion was very good. The nails inlaid on the silicone must be easy to fall off. No matter how they are fixed, it is difficult to fix a soft material and a hard material well.

If the nail is placed on the finger position of the robotic palm, it can be very stable.

Just put a nail buckle on the position of the mechanical finger, not only can it be fixed, but also you can change the nail as you like. If you don’t like this nail or there are too many scratches on the nail, just change it.

That's a good suggestion.

It is absolutely possible to set a standard for the specifications of the nails, such as the size and curvature. In the future, there will be a standard for male nails and a standard for female nails, so that quantification can be realized instead of individual customization.One-by-one customization can be closer to the user's fingers, but customization means high cost. For those families who are struggling to buy a robotic arm, customizing nails is tantamount to worsening the situation.

Therefore, nails can go in two directions: customization and mass production. Those who have money will support customization, and those who have no money will buy mass-produced ones to meet their needs.

Liu Yun couldn't help but praise himself. He felt that he was a real genius, and he thought of setting standards.

Before he crossed over, he understood the truth that downstream companies use other people's things, midstream companies produce things, and upstream companies set standards, and the standards set by upstream companies must be followed by others.

Of course, if you want your own standard to become an industry standard, you must have a very solid industry reputation. It is impossible for individuals to set standards, which is a bit too nonsense.

"Song Fangqing, that's the kind of solution you want. In the final analysis, you still wear the nails. You can design whatever you like." Liu Yun didn't make a final decision. He's not a dictator. Let's discuss things, we are all friends.

"I think it's all right. It's best to put nails in the mechanical fingers and then use plastic nails. Why don't you wear 100 nails, so you can change them frequently." Song Fangqing said her own idea.

Liu Yun nodded, and said to Deng Yunqi: "Deng Yunqi, you can design a plastic nail cover based on the nails of Song Fangqing's other hand later, and when the design is finished, ask someone from the machinery manufacturing factory to slightly modify the nail part of the robotic arm. That's it."

Deng Yunqi nodded, designing a nail, it couldn't be easier for her, it was very easy.

"In addition, our company will buy another nail manufacturer. As long as it is not a troublesome industry, we can buy it and do it ourselves. Everything about the robotic arm will be managed by Song Fangqing in the future, including the nail factory that will be acquired later. and human biomimetic skin factory."

"I don't care about the management. Song Fangqing, you can figure it out. If you want to change the boss, you can change it. If you don't want to change the boss, you can use the previous boss. You are free." Liu Yun said to Song Fangqing.

Song Fangqing nodded, and suddenly felt a lot of courage in her body, mainly because she had no management experience before, and it was the first time she was appointed to such an important position. Not only is the position important, but it is not normal to manage several factories at once. many.

"Let's talk about the texture next. There is nothing to say about the texture. Make relatively light creases on each joint bone on the inner side of the finger. The texture on the inner side of the palm should also have it. Like the love line or the career line. There must be a marriage line, and there are countless small lines around these four big lines. My goal is to have one, and that is to imitate the real."

Song Fangqing was a little moved. Although she knew that Liu Yun was just trying to complete the product, he was really moved by such a meticulous design that went down to every little detail.

"Then under the big textures of the love line, career line, and marriage line, put some shallower textures like human fingerprints, so that the fingerprints run through the inner side of the palm."

"Next, let's talk about the outside of the palm. The nails on the outside of the palm have been finished. Let's talk about the design of each finger. There must be folds at each joint. Making the folds wider than the knuckle folds above, and being as realistic as possible, was a top priority."

"Then there is the place where the fingers and the palm are connected. This place should be raised during the mechanical design. When the real thing comes, it will be decided whether to put a tendon on the silicone skin or put a tendon in the mechanical palm. "

"There must also be pores on the back of the hand. The size of the pores must be restored as much as possible, as well as the fine hair on it. Then there are blue blood vessels on the back of the hand. This must also be fake. The color of the blood vessels will be discussed later. "

"At that time, the silicone sleeve will completely cover the mechanical cover and extend to the wrist by five or six centimeters, so that it will not be visible when wearing long sleeves."

"There is also a buckle that can be designed at the end of the silicone sleeve. Occasionally, the wrist can be loosened, so as to save the wrist from sweating and itching."

Liu Yun bombarded so violently that the five people in the ward almost fell asleep.

"Okay, let's talk about the color number later, let's relax."

With a whoosh, the person disappeared.
