It was already nine o'clock in the evening, and it was quiet in the hospital.

When He Xiao ran into the inpatient department, he was immediately stopped by the nurse on duty.

"Little girl, what are you going to do? It's past the time to visit, come back tomorrow! ”

As the nurse spoke, she looked at He Xiao and saw an eager look on He Xiao's face: "Doctor, I'm here to see my brother, he was injured on the battlefield in the south and is hospitalized here, my brother ...... He is a battle hero! ”

"What's your brother's name?"

"He Liang. Do you know him? Was he seriously injured? ”

The nurse hesitated for a moment: "Okay, you go, in bed 18, be careful, don't make loud noises, be careful to disturb other patients, at most five minutes." ”

"Thank you, thank you."

He Xiao trotted all the way, rushed to the ward area, found the ward where the 18th bed was located, and gently pushed open the door.

The people inside did not sleep, after all, lying in a hospital bed all day, where could they sleep, but, as soldiers, they all had discipline, even if they stared at the ceiling with their eyes open, they would not make a sound.

When the door opened, the people in the three beds looked out and saw a young and beautiful girl walking in, holding her proud chest.

One of them suddenly widened his eyes: "Xiaoxiao? What are you doing here? ”

Sure enough, it's my brother!

He Xiao walked to his brother's hospital bed in a few steps, with a nervous look on his face: "Brother, where are you injured?" Where did it hurt? ”

"It's okay, Brother Ling is very good, in fact, he can be discharged from the hospital a long time ago, but the doctor won't let me." A smile squeezed out of He Liang's face.

"Hmph, lie, I'll see."

He Liang pulled away the quilt: "See?" Your brother is in good health and has complete parts. ”

However, as he moved, the wound on his leg was pulled and it hurt a little, and he pretended to be calm, and glanced down with his gaze, intentionally or unintentionally.

He Xiao's eyes were puzzled, and he touched his brother's upper body with his hand, and sure enough, they were all intact, except for some external injuries, there was no major problem, and he didn't see the incision of the operation, but if it was a minor injury, how could he be hospitalized?

"It's not early, you can go back." He Liang said: "The hospital has hospital regulations. ”

"Oh, then I'll come back to see you tomorrow."

"Hmm."

He Liang looked at his sister who was about to turn around and leave, and finally breathed a sigh of relief, he will be discharged from the hospital tomorrow, don't let his sister know, as for the future...... If you can hide it for a day, it's a day.

However, at this moment, He Xiao suddenly ripped off the bottom of the quilt.

It was empty, there was nothing.

At this moment, He Xiao's tears fell like beads with broken threads.

He Liang was a little overwhelmed for a while, he didn't want his sister to know, he was afraid that his sister would cry.

"It doesn't matter, although your brother has lost his legs, but at least he is still alive, in the south, your brother is lucky like this, even if your brother can't stand up in the future, he is still a man!"

"No, brother, you will still be able to stand up in the future, and you can still walk like a normal person!" He Xiao's tone was choked, but he was also very firm.

"What do you say, can you give your brother a pair of legs again?" He Liang's heart was like a knife, but his face still had to show a look of indifference.

"Yes, brother, I'm currently working on a project, this project is to give people an extra pair of legs, and when I wait until tomorrow, I will bring you my results!" He Xiao said firmly: "Brother, you wait tomorrow!" ”

He Xiao wiped his eyes with his sleeve, then turned around and walked out, five minutes is too short, my brother still has a long life!

Walking to the door, she stopped again: "Brother, I'll come back in a few days, and when I finish your legs, I'll bring you over." ”

Looking at the back of He Xiao leaving, He Liang smiled: "My sister, college student." ”

The comrade-in-arms on the hospital bed next door was envious: "Your sister is so beautiful, do you have a partner?" ”

"What, the toad wants to eat swan meat? Let me tell you, my sister is a top student, and her object is also a college student, and they are engaged in scientific research together. ”

"Yes, it's indeed a top student, she just said that she wants to make you a pair of legs."

He Liang's eyes were full of expectation, yes, my sister is a college student, my sister said, if you want to make a pair of legs for yourself, then you will definitely be able to make it, and when the time comes, no matter how difficult it is, you will use the legs made by your sister to stand up again!

A week later, Army General Hospital, Department of Rehabilitation and Physical Therapy.

Zhao Xiangyang, an old expert in his fifties, looked at the long medical record book with a complicated look.

"Alas, they are all young men, they have become crippled, how can they live in the future."

"Yes, they are all fighting for their country." The nurse on the side said: "They are all heroes, and even though they are disabled, they don't want to affect the country, and they want to return to their hometown after being discharged from the army, if only our hospital had a way to help them." ”

"Hmm." Zhao Xiangyang said: "There is a way. ”

Knock knock!

At this moment, there was a knock on the door outside: "Section Chief Zhao, your guest is here." ”

Zhao Xiangyang stood up and looked at the door, where a tall figure appeared, about the same age as him, with a big beard and a glint in his blue eyes: "Zhao, we meet again!" ”

"Robert, welcome, welcome." Zhao Xiangyang said: "A few years ago, when I went to the United States for exchange and study, I heard that your woodway company manufactures medical rehabilitation equipment, so I would like to ask you to understand your progress. ”

"Zhao, then you have found the right person, our company is the most professional in the world!" "Now, we have developed the first walking training robot for rehabilitation, called WalkHelp, which can help patients recover," says Robert. ”

"What group of patients is this robot targeting?" Zhao Xiangyang continued to ask.

"The main thing is to help people who have difficulty moving to get back to walking, such as limb pain, muscle spasms, and even people with intestinal and digestive problems, in this way, they can walk again."

"What if it's an amputee?"

Robert's eyes widened: "Zhao, are you kidding, amputees, the best choice is to sit in a wheelchair, we help people with legs, legs are gone, how to walk?" If only one leg is amputated, we can contact the company that produced the prosthesis, if both legs are missing...... That's not going to keep your body balanced at all! Zhao, you are an expert in this area, don't you understand these things? ”

Zhao Xiangyang frowned, of course he knew, but seeing those young men lose their legs and lose their ability to walk, he had an indescribable feeling, he wanted to help these people, he wanted to let these people regain their ability to walk!

But now, it doesn't seem to work.

Even the most technologically advanced Americans can't do it!

It seems that there is only a second best thing, some people are only injured in their legs and cannot walk again, but these people can still use it.

"How much does it cost for a robot like you to help people walk and train?" Zhao Xiangyang asked.

"Three million dollars."

"What?" Zhao Xiangyang's eyes widened, this is too expensive, right? Needless to say, three million dollars, even if it is thirty thousand dollars, this is money that many people will never make in a lifetime!

"Zhao, you should know that to develop this kind of robot, it costs a lot of money, our woodway company was established in 1975, and since then it has been working hard in the professional system of competitive training, commercial fitness and medical rehabilitation, our walkhelp robot, has been established since 76 years, and has been developed for more than ten years now, invested a lot of money, and the price will certainly not be cheap."

Zhao Xiangyang's mood dimmed, it seemed that his idea was about to come to naught, and he couldn't help those soldiers who had amputated their limbs, and even those who had inconvenient legs and feet because of injuries, so he still had to continue to use the old methods, acupuncture, and physiotherapy......

At this moment, there was a sudden commotion outside.

"Wow!"

", that's awesome!"

Boom, boom, boom! There are also some unique stomping sounds, like soldiers kicking the right steps!

Listening to these sounds, the nurse who had been staying in the room hurriedly walked out, wanting to stop this noise, this is a hospital, and it needs to be quiet.

However, when she pushed open the door and looked outside, her eyes widened and her mouth opened wide: "Wow! This, what kind of advanced equipment is this? ”

"What's that?" Zhao Xiangyang became interested.

"Section Chief Zhao, you can come out and take a look." The nurse said, "The patient in bed 18 got up and walked on his own!" ”

18 beds? That combat hero with both legs amputated?

Zhao Xiangyang looked at Robert: "I'm sorry, Mr. Robert, you can sit down for a while." ”

With that, he strode to the door, taking off his reading glasses.

A young man walked up to him.

It was very warm in the hospital, and there were radiators in the corridors, so the young man was wearing only a thin military uniform, and the two lower trouser legs were empty, but his body was still upright! The sides of his two legs, the metal structure bracket that shone a little in the light, the bracket hung from his waist, and it was securely attached to his upper body, and there were several rope sleeves at the crotch to support the weight of his body.

The lower part is a two-section structure, the shape is very stout, it looks like it should be made of aluminum alloy, with a metallic luster, the upper half is tied to the thigh with a rope sleeve, the lower half is directly exposed outside, and the bottom is stuffed into a pair of yellow rubber shoes, you can see that there are metal soles inside.

There is a hinge between the upper and lower sections, and there is also a hinge between the bottom and the metal soles.

What is it? Mechanical legs?

The young man was obviously very excited, and as he walked, he said to the girl next to him: "Xiaoxiao, you are so good, you really made me a new pair of legs!" It's like this leg grows on me! ”

"Brother, don't worry, go slowly, accumulate some data first, I will continue to modify the program according to these data, which can make you walk more freely, and when there is no problem walking, let's talk about running."

"Can I still run?" As the young man spoke, he opened his thighs and took a sharp step forward, this time he was a little too strong, and he suddenly couldn't support his balance, and his body lay forward.

Everyone suddenly exclaimed, the girl just wanted to step forward to protect the young man, but the young man's other leg took a step forward suddenly, and actually let the body regain its balance!

The big guys all made a false alarm and let out a long boo.

"He Liang? Where did you get these mechanical legs? Zhao Xiangyang's tone was full of surprise.

As a doctor, Zhao Xiangyang has always looked forward to using advanced technology to make soldiers who lost their legs on the battlefield walk again, and he also found American experts for this purpose, but he didn't expect that the Americans did not have this technology, and only helped people with weak legs and feet to walk.

Now, his patient He Liang is wearing a pair of mechanical legs! And you can walk!

Don't underestimate this walking, it took millions of years for human beings to free their upper limbs, walk on two legs, and they won't fall, just this one requirement, stumped many people.

Of course, there are already walking robots, but only the robots walk on their own, and they want the robots to walk according to human ideas, tacit cooperation, and the requirements are higher.

"My sister made it for me."

Your sister?

Zhao Xiangyang looked at the girl beside He Liang: "This female comrade, are you?" ”

"My name is He Xiao, a student at the School of Engineering of Capital University, and I am in my third year of graduate school this year." He Xiao said: "I am currently researching human exoskeletons, and I am very glad that I chose this project to make my brother stand up!" ”

The first product developed by He Xiao was a non-powered exoskeleton, which only assisted people to bear weight, but when it was developed, there was also a research plan for a powered exoskeleton, and a week ago, after coming out of her brother's ward, she began to do research day and night.

The drive motor has been designed a long time ago, only processing remains, the control circuit also needs to be improved, the program needs to be upgraded, and now, she still has two panda eyes, but seeing that this improved device can be worn by her brother and walk normally, He Xiao's heart is full of pride.

Thanks to the fact that I chose this direction, and thanks to meeting Mr. Qin, otherwise, I would not be able to help my brother! Moreover, research and development requires a large amount of money, all of which are provided by Mr. Qin!

"How did you do that?" At this moment, Robert walked out from behind Zhao Xiangyang and looked at the things He Liang was wearing under him in surprise: "It can actually be worn by people who have lost their legs, and they can walk very steadily!" It's nothing short of a miracle! ”

Robert said, walked up to He Liang, circled around He Liang, and finally fixed his eyes on the box he was carrying behind him.

"What program do you use? What chips were used? Is this electric? ”

"You are?" He Xiao looked at him suspiciously and curiously.

"I'm an engineer at Woodway in the United States, and we're working on a similar robot, do you sell this kind of technology? If I sell, I can pay a high price of $100,000! ”

The muscles on Zhao Xiangyang's face twitched twice: "Robert, your kind of rehabilitation training robot, what about three million in one set, right?" ”

In the past, when they were in the United States, the relationship between the two was not bad, after all, there was an intersection in each other's work fields, but I didn't know that the other party would be so shameless, a broken system sold for three million, and now I see that we have it here, and I actually want to buy it for 100,000 dollars!

"If you don't see this product in front of you, then you really have to sell you three million sets, and now, we are willing to sell you a set for $50,000!" Robert said: "Your technology is very good, I just opened 100,000 at a price that is too low, how about 1 million?" Little girl, think about it, a million dollars, what a huge fortune that is enough for you to enjoy for the rest of your life, do you want to go to the United States? On behalf of the company, I sincerely invite you to join our company with an annual salary of 100,000 US dollars! ”

Robert said it in English, and most of the people around him didn't understand what he was talking about, but you could see how excited the expression on the foreigner's face was, and he was obviously very satisfied with the Dongfang product.

"Is a million dollars a lot? What is your company's annual profit? ”

"Our company's annual revenue is tens of millions! Of course, this is also because our company has invested a lot of money in research and development, otherwise, our company's annual revenue can be more than 20 million US dollars! ”

"It's only 20 million, our President Qin just received an order of 100 million US dollars some time ago, for our group, a small company with an annual income of 20 million US dollars, there is no capital to talk to us at all, brother, let's go back!"

Gotta go back, it's time to recharge!

100,000 dollars, 100,000 dollars, who is rare! This is clearly to take advantage of the robbery, what foreign country to go, we are good in the East! Mr. Qin is right, the United States has developed science and technology because they plundered the technology of other countries, so they will not be fooled.

The unpowered exoskeleton also needs electricity, just supplied to 51 single-chip microcomputers to monitor the work of various parts of the body and carry out simple coordination, this powered exoskeleton needs to provide energy to the joints, only relying on a simple battery, the energy density is too low, and it will not take long.

However, other drive schemes such as hydraulics and pneumatics are also unreliable, since Mr. Qin has chosen the electric route, there must be his reason, and so on, the battery technology will be improved, and the energy will be more abundant, now the first program is done!

51 single-chip microcomputer can only drive the unpowered exoskeleton, this dynamic program complexity is greatly increased, so, the inner control part is a 386 chip, which is also the most advanced processor chip that can be bought in the civilian market at present, but there is only such a piece of redundancy, so, it is removed from the mechanical dog.

At that time, Zhang Shengwang just watched and didn't dare to say anything.

This system is not perfect, there are still many things to improve, now, let my brother walk on his own.

He Liang's body turned flexibly, and then walked in the direction of the ward, and Robert opened his eyes wide, looking at the two mechanical legs.

Perfect, too perfect, this control technology is not simple, how exactly do they do it? What Mr. Qin, what just received a big order of 100 million? Are they bragging? When did the East have such an enterprise?

Robert turned his head and looked at Zhao Xiangyang.

"Zhao, do you have such a company in China?"

"Of course, Pacific Group." Zhao Xiangyang said: "I heard before that Pacific Group invested and Capital University set up a project to study human exoskeletons together, but I didn't think much about it at that time, I didn't expect their progress to be so rapid!" ”
