Chapter 309 The hope of rebirth with a broken arm

"Junior Sister Lin, this is our No. [-] laboratory. It has been put into use for two months. At present, the research on high-efficiency foot-and-mouth disease vaccines is in this laboratory."

"What about the staffing?" Lin Yumo asked.

"I am the general manager, but my energy is mainly focused on my own medicines, and Junior Sister Helen is the general manager in charge of this project.

Half of the experimenters below are from Vietnam, and the remaining half are from China.

This is according to our agreement with the Vietnamese government to help them cultivate talents in this area. "

Lin Yumo nodded.

Later, under the leadership of Fan Shigang, Lin Yumo and Guo Yuan visited a circle of laboratories.

After spending the whole morning, Lin Yumo basically figured out the current situation of the laboratory.

It has to be said that Fan Shigang is a good talent. In such a short period of time, the guarantee of the laboratory has been raised, and the entire laboratory is managed by him.

To be honest, Lin Yumo felt that when she was studying in the past, her perception of Fan Shigang had some deviations, and Fan Shigang was far more powerful than she thought.

Thinking of this, Lin Yumo said with a smile: "Brother Fan, I owe it to you all this time."

"Junior Sister Helen is mainly in charge of the lab. I just helped with the recruitment. You should thank her."

"Then Senior Brother Fan has been researching your medicine all this time?"

"That's right, thanks to the venue you provided, my medicine can be released so quickly."

"Has Senior Brother Fan thought about how to use this drug to make money?" Guo Yuan asked.

Fan Shigang shook his head and asked him to engage in scientific research. He is really not good at making money.

"I have two immature ideas here, do you want to listen to Senior Brother Fan?"

"Of course, Mr. Guo is better than me no matter how you look for it!"

"Senior Brother Fan, I suggest you reduce the effect of the medicine first."

"Reduce the efficacy of the medicine?"

"Yes, I remember you said before, if it is the original version, you only need to take one pill a week, combined with one subcutaneous injection, and use it for 30 weeks continuously, you can guarantee to prolong the cell's self-repair mechanism for 10 years, right?"

Fan Shigang nodded.

"I suggest that you reduce the amount of medicine you take to only manage for a week at a time. It needs to be taken for a long time to be effective, and then what kind of essence should you add! Or something like a mask."

"Mr. Guo, you mean to sell it as cosmetics?"

"Yes, this is the least noticeable and the most profitable. She spends tens of thousands of money on cosmetics a month. The average woman is not as rich as her, but she will invest in cosmetics every month. Some." Guo Yuan pointed to Lin Yumo and said.

At this time, Fan Shigang also understood.

"Mr. Guo, we just need to set the medicine to a level that all women can afford, and we can make a lot of money by relying on sales, right?"

"That's right, there is also a VIP version for rich women, the effect is no different, the price is at least 3 or 4 times more expensive, otherwise rich women will think our products are too cheap, the effect is sure not good."

"Ahem! I'm still sitting here! It's almost done!" Lin Yumo rolled her eyes and said.

"In short, the idea is almost like this. Mr. Fan, you look at the arrangement. We will help you with the specific patent when the time comes."

Fan Shigang nodded excitedly.

He seemed to have seen a golden mountain falling towards him.

Although the share of this drug is 73 percent, Dragon City Biotech's 7 percent, but according to Guo Yuan, 3 percent is also an astronomical figure!

"Senior Brother Fan, don't rush to be happy, give us 5 sets of your medicine." Lin Yumo said.

Fan Shigang nodded and brought 5 sets of medicine.

Guo Yuan and Lin Yumo stayed in Vietnam for a week, and they took the first medicine that day.

They didn't feel much for the first three days, but from the fourth day onwards, both Guo Yuan and Lin Yumo felt that some minor ailments on their bodies were much better.

Guo Yuan's muscle strain from exercising, and Lin Yumo's sore shoulders both eased a lot.

This means that the drug is really working.

Lin Yumo was very happy. Originally, she thought she was several years older than Guo Yuan, and she would look a little old when she got married.

Now that worry is gone.

On January 1th, the two returned to China together.

The medicine was brought in under the name of Dragon City Bio.

"Guo Yuan, this medicine is for you. It is just right for your sister to take this medicine at her age."

Guo Yuan nodded, took the medicine and asked casually, "Who are you going to give the remaining two copies to?"

"Give it to Yurou! There is another copy that I want to study myself."

"then you."

"Dinglingling~" Before Guo Yuan finished speaking, the phone rang.

He took out his phone and the number on it was a mess of characters.

This kind of call is most likely from someone above, he quickly answered the phone, and then Director Liu's voice came from the phone: "Guo Yuan, you go back to China!"

"Well, I'm back, is Director Liu okay?"

"Yes, did you just invest in an intelligent robot company?"

"Yes!"

"Have you seen their mechanical arms?"

"Yes, isn't this trying to make a robotic arm with as much precision as possible, and create a "rebirth of a broken limb"!"

"I happen to have a similar project here, are you interested in communicating with someone?"

"With people? With whom?" Guo Yuan asked in a daze.

"Bai Jingwen."

"Have not heard."

"He is an academician of the Chinese Academy of Sciences and an authoritative expert in machinery."

"Academician? That's for sure!"

"Then write down his cell phone number, his number is"

Guo Yuan winked at Lin Yumo, and Lin Yumo immediately helped Guo Yuan write down the phone number.

"Academician! Your superiors value you very much!"

"It should happen to be that the research done by Academician Bai and I are the same."

Guo Yuan thought for a while and didn't call directly, but first sent a text message to introduce himself.

After a while, Academician Bai came back with a reply letter, which was from Academician Bai's students: "Mr. Guo, the teacher is busy, if you have anything to do, you can send it to the teacher's mailbox 163, and the teacher will reply to you later. "

After Guo Yuan received the reply, he discussed with Lin Yumo about the problem with Zhou Songfeng's robotic arm, sorted out the problems and sent them to Academician Bai's mailbox.

Two hours later, there was a notification on Guo Yuan's WeChat that a new friend was added.

The friend's name is Bai Jingwen, and Guo Yuan passed without hesitation.

As soon as Guo Yuan passed through here, a video call came from the other side, and Guo Yuan answered it without hesitation.

Academician Bai is an old man who looks 60 years old. His hair is gray, but he looks very energetic.

"Guo Yuan, I read the email you found, and based on your data, I used the star engine to simulate your mechanical arm.

There is a big problem with this robotic arm of yours, which is that it is not accurate enough.

Through simulation, I confirmed the reason for the low accuracy of the robotic arm, mainly due to the vibration caused by the internal clearance of the reducer. "

Hearing this, Guo Yuan turned on the laptop and asked 01 to unfold the simulation map of the robotic arm. According to Academician Bai, he marked the problem points, and then asked 01 to perform a repair simulation.

After the restoration simulation, the accuracy has improved a lot.

Guo Yuan's eyes lit up, and he quickly asked, "Then Academician Bai, should I notify the other side to remove the reducer and replace it?"

Academician Bai waved his hand and said, "Don't be so anxious, I have to confirm the parameter data of the reducer again."

"I'll send you the detailed data."

Bai Jingwen hung up the video after receiving the data.

Half an hour later, Bai Jingwen called again with a video: "Hey, Guo Yuan, I have confirmed the gap data in the reducer.

To eliminate the vibration caused by the clearance of the reducer, in fact, there is already a mature solution in the industry, that is, dual-motor drive clearance elimination.

At present, the 840D numerical control system of German Siemens company uses this method. By adding a torque compensation control link in the servo loop, a part of the rated torque of the motor is used as the anti-backlash bias torque, so as to realize the dual-motor master-slave anti-backlash control function. "

When Guo Yuan heard that the industry already had a mature solution, he hurriedly asked Bai Jingwen about the specific details of dual-motor drive backlash elimination.

After Bai Jingwen and Guo Yuan talked, Guo Yuan then asked: "Academician Bai, do you know anything about this method?"

Bai Jingwen nodded and said, "I've studied this method and realized it myself, but at that time it was limited by the algorithm performance of the control system, so the final realization effect was not ideal."

When Guo Yuan heard this, didn't he hit himself with a gun?He needs to consult Bai Jingwen for mechanical matters, but in the field of algorithms, he asks himself that there are not many problems that can bother him.

"No wonder Director Liu called me, isn't this the best partner!" Guo Yuan thought in his heart.

Then Guo Yuan said with a smile: "Academician Bai, isn't this a coincidence? You should also know what I do. I think with the cooperation of the two of us this time, this subject will definitely be conquered! I'm so lucky now That email I sent you earlier."

Bai Jingwen smiled when he heard Guo Yuan's words.

In fact, when Director Liu contacted him yesterday, he wanted to take the initiative to find Guo Yuan. He decided to communicate with Guo Yuan because he took a fancy to Future Technology's technical strength in software algorithms.

It's just that Academician Bai didn't expect that the first project he cooperated with the other party would be dual-motor drive backlash elimination. He originally imagined that he would help Guo Yuan solve the problem of the robotic arm first, and then invite the other party to participate in the project at hand and provide some Algorithm design support.

It is also good to directly carry out the subject of dual-motor drive backlash elimination. Bai Jingwen is very clear that as long as he can complete this project, he will at least make a big splash in China.

"Guo Yuan, since the subject is already in front of me, I would like to invite you to participate in this project, do you agree?"

Guo Yuan has no reason not to agree. If he can complete this project with Bai Jingwen, firstly, his own robotic arm project will be considered completed, and secondly, he can continue to learn from Bai Jingwen during the project research process, so that when the project ends At that time, the shortcomings of my lack of practical experience were filled.

Thinking of this, Guo Yuan gave Bai Jingwen a hearty smile, and replied: "No problem, I wish for it!"

Bai Jingwen was also very happy, and he promised Guo Yuan: "Guo Yuan's project is jointly developed by the two parties, and your future technology will provide the network technology, and I will conduct realistic simulations and experiments.

We take advantage of our respective elemental advantages, learn from each other's strengths, divide labor and cooperate, and jointly realize technological innovation. In this way, both parties share the results, which is beneficial to both you and me. Moreover, your robotic arm is ready-made and does not cost much. "

Bai Jingwen's proposal was in line with Guo Yuan's intentions, and he even felt that he had taken advantage of it.

Guo Yuan thought for a while and said, "Academician Bai, our company will pay for this project!"

"Isn't that good? Let's all work together!"

"It's good for us to come. This project doesn't need much funds. On the project, I prefer to cooperate with you, Academician Bai, so I need you, Academician Bai, to deal with the communication with the school."

To be honest, Guo Yuan doesn't mind this kind of capital expenditure. Academician Bai said that the results of this scientific research will be shared by both parties, which is more in line with the interests of future science and technology.

On this basis, Guo Yuan has already taken advantage of it, and it doesn't matter if he pays a little more.

After Guo Yuan said that, Academician Bai didn't object anymore, and nodded in agreement.

After the two discussed some cooperation procedures, they directly entered into a new round of discussions on the method of dual-motor drive backlash elimination.

The main purpose of confirming the cooperation method is for the distribution of scientific research results, so although the cooperation intention has just been confirmed, it will not affect the progress of the research work.

When it was almost time for dinner that day, Guo Yuan had already understood the principle of the method of dual motor drive to eliminate backlash from Academician Bai.

I also understood why Bai Jingwen had studied this project before, but finally shelved it.

The performance of the algorithm program for dual-motor drive control is insufficient, and effective control cannot be achieved. Therefore, compared with the single-motor drive, the dual-motor drive originally used for anti-backlash increases the complexity of the drive, and ultimately fails to achieve the predetermined anti-backlash goal.

After confirming the algorithm requirements for dual-motor drive with Bai Jingwen, Guo Yuan hung up the video.

"01."

"I'm here!"

"Did you hear what Academician Bai asked just now?"

"heard it."

"The relevant algorithm will be handed over to you."

"Good Mr. Guo Yuan."

"How long will it take?" Guo Yuan asked.

"If you start doing it now, you can finish it in 32 minutes."

"Well, after finishing it, send the algorithm to Academician Bai every two days."

"Good Mr. Guo Yuan."

If the accuracy problem of the robotic arm is solved, the next step is how to minimize the size of the robotic arm while maintaining such accuracy.

When the robotic arm can be reduced to the size and thickness of a normal human arm, the weight is similar to that of a normal arm, and the accuracy is not affected, then the "rebirth of a broken arm" can really be achieved.

If the robotic arm is done, the legs are even simpler.

The flexibility of the palm is much higher than that of the soles of the feet. The palms are all done, and the soles of the feet only need to consider the load-bearing and joint passage.

If this technology is realized, it will really be a boon for thousands of people with disabilities. It is no exaggeration to say that it will benefit the present and benefit the future.
