Chapter 167 Kirin Wings ([-]) Transformation

190,

Kirin Wings just started contacting the district and county governments, and began to try to establish a cooperative relationship with the government, deploying express boxes in various communities and streets. In less than a week, Liu Shuangshuang found Qi Na and asked about this matter. Qi Na was very curious: "This It's just our intention, how did you know it so quickly?"

Liu Shuangshuang chuckled: "You have to understand, who is the boss in Ningnan now."

Qina thinks so too, the relationship between himself and Du Juan is so close now, although he tried his best to draw a clear line with the political forces, but in the eyes of outsiders, it is deeper, but he doesn't care anymore, you can be strong without desire, he repeatedly told himself , I want to hold on to it.

Liu Shuangshuang asked him to come and report to Secretary Du Juan.

After Qi Na told Zheng Xiumin about the situation, he reported to the CEO and asked for leave. The full-time driver of the website sent him to the municipal committee.

The meeting this time was at the same place as the meeting half a month ago, the two sides have changed differently, Du Juan has more ups and downs, but now the overall situation is finally under control, while Qi Na is the same as before, adhering to the belief that everything depends on himself, Not stubborn with each other, so the mentality is more peaceful. .

However, Du Juan did not mention a single word about Feng Shuangying's corruption case, but only mentioned the operation status of Life Online. Qi Na introduced that the office environment restricted its development, and Life Online was looking for a new office environment.

Du Juan let out a cry, and Qi Na glanced at her, Du Juan was still looking at him with a smile, he was a little uncertain about the meaning of her asking him to come.

After talking about Life Online, I will continue to mention Kirin Wings. This is naturally a supporting package for Life Online. At the beginning, Kirin Wings was established to make some articles on hardware, and the first project was express boxes.

Du Juan was full of interest in this project and asked more details. Qi Na also mentioned the robotic arm that was about to start testing. Du Juan was even more curious. There is still a gap in the arrangement, or go to the scene to see?!"

Du Juan nodded: "That's a good suggestion."

Qina glanced at Liu Shuangshuang, not understanding their purpose.

Du Juan added: "By the way, I'll go to Life Online to check it out."

After leaving the municipal committee building, Liu Shuangshuang and Qi Na stood side by side, and when they saw no one around, they said to the dull Qi Na: "Look at you! Can Secretary Du invite anyone? She said to go to Life Online, it's a gift to you." Great face."

Qina scratched the back of her head: "But what's her purpose for going? I have to make some preparations."

"Fart preparation, you just need to introduce it well, she is giving you a gift." Liu Shuangshuang said.

"Give me a gift?" Qina was extremely curious.

Back at the company, he called a meeting with the heads of the two companies, Emily and Wu Jun, and introduced that Secretary Du Juan would come to inspect tomorrow, and asked them to do a good job of display and reception.

Wu Jun is very experienced and immediately arranged for some KT display boards to be placed on both sides of the relatively empty corridor for presentation to the guests.

And Emily also learned a lot and went back to prepare.

Qi Na was worried about the operation and debugging of the robotic arm that had just been put in place.

The robotic arm was purchased from a company in Guangdong. The two technicians who came here were a little dull and the work progress was very slow.He repeatedly emphasized that the requirements of Kirin Wings were too special, and complained that the calculation volume of this robotic arm was too amazing.

In order to cooperate with the operation of the robotic arm, Qi Na has fully opened a set of virtual server modules of Kirin Wings, a total of fifteen virtual machines. The resource usage of the entire device has exceeded [-]%, but it still cannot meet the needs of the operation of the robotic arm. operation.

Qi Na deeply believes that the company's hardware is not bad, but the software is obviously far from the world's highest level.But now the far water can't quench the near thirst.He had no choice but to ask the manufacturer's technicians to guarantee tomorrow's demonstration. As for the loss of the mechanical arm caused by this, it is not their responsibility.

The factory technician said to him impatiently: "Our equipment is only used for two simple operations on the production line. Your requirements are too high and too many, and we cannot realize them."

Qi Na patiently said: "You have an API interface that is open to the outside world, but the documentation you provide is limited. If possible, you can provide a more comprehensive interface guide, and we can cooperate with you in secondary development."

"Our introduction to other companies' interfaces is like this. Others can do it, why can't you. Our equipment is good if it can run when it is powered on. If it can't run your software, that's your problem." The technician is still arguing.

Qi Na gradually became angry, but he still had to rely on them tomorrow, so he didn't want to be troublesome, so he suppressed his anger and said, "If you successfully debug the equipment, it means that we will purchase ten to two units before the end of the year. Ten mechanical arms."

"That has nothing to do with us, you can talk to the salesman." The technician turned away the opportunity in a blink of an eye.

Qina thought how such an employee could stay in the company!It is estimated that the other party just felt that Qilin Wings was an unworthy customer, so they arranged for such a technician to serve.

He didn't want to communicate with the technician any more, so he went back to the office and called the manufacturer. The salesperson was very enthusiastic. He heard that the technician's attitude was very bad, and kept saying that it was impossible, saying: "Our boss knows that you are a new customer. Testing, so it is very important, and the technical engineers arranged in the field are the best here. How could it be poor!"

Qi Na was speechless, so he had no choice but to ask the engineer next door to convey his opinion. The next day, the mechanical arm must work normally.

The salesman immediately agreed when he heard Qina's bad tone.But he said: This is our best technician, there will definitely be no problems.

Qina didn't say much, hung up the phone, and began to arrange emergency plans.When Du Juan came over, it would be a pity if the core product could not be demonstrated.

Liu Shuangshuang said that Du Juan would give gifts, and wondered if the demonstration of the robotic arm would affect the size of the gift package.

Just as he was thinking wildly, there was a commotion in the laboratory. Qina walked out quickly, and saw the short factory engineer angry at Emily: "Aren't you suing? If you have the ability to debug it yourself, I will quit."

It turned out that the manufacturer had called, probably blaming the technician, but instead of absorbing the problem, the technician acted wildly, causing Qi Na to shake his head.

Emily knew that there was an important event tomorrow, so she desperately pulled him with her colleagues to prevent him from leaving.

After talking back and forth for a long time, the short engineer did not just step down and die down, but instead became more and more noisy, yelling at the Qilin Wings, Emily blushed from holding back, but was still smiling.Several technicians were also laughing.

What Qi Na saw earlier was that his heart was angry, how could he let his colleagues suffer this insult, he stopped Emily, and said loudly: "Let this person go, he will debug these two devices, call an engineer, really think he is a grandfather 40, nothing, I can still fight with Qilin Wings."

Qi Na has done technology and has seen the face of a class of technicians. He feels good about himself, puts on airs, bullies laymen desperately, and acts like a turtle in his shell when he encounters problems, without seeking to make progress.

It may be that Qilin Zhiyi didn't entertain them well, and after coming to Qilin Zhiyi for three days, they repeatedly shouted to leave.

The chunky engineer nodded to Qina: "You are awesome."

Seeing that this man was still stubborn, Qi Na didn't know whether to laugh or cry, and didn't bother to talk to them, and asked Emily to throw out all their tool bags together.

But they are gone, how to debug these more than 40 robotic arms next?
The colleagues in the R&D department all looked at Qi Na blankly.

These are all recent graduates of the corresponding majors from nearby mechanical and aerospace universities. Their biggest achievement is to be a toy-grade robot or a model of a quadrotor unmanned aircraft.

However, they are very unfamiliar with industrial-grade robots such as mechanical arms, and the engineers of the manufacturer are very conservative, so after these three days, their understanding of mechanical arms is still zero.

Qi Na said to them: "Come on, we'll work overtime all night today, Emily, you can't treat your belly badly if you work overtime, and order a delicious takeaway."

Colleagues saw that the boss wanted to do it himself. Although they heard that the boss was awesome, most of the colleagues had not seen Qina do it himself.Then everyone cheered.

Colleagues who don't know the situation may think that they are cheering and can have a full meal.

The robotic arm is fixedly placed on the workbench, with a set of interfaces on the side, including a Gigabit network interface, a Console port, and a power supply interface.

Qi Na took a laptop, connected it to the console interface through a USB cable, and logged in to the control background of the robotic arm.

This control background uses Intel's Atom CPU, and the memory is only 256M, but it uses onboard components. Although the configuration is much lower than that of a home computer, the power consumption is low and the heat generation is low. Ordinary entry-level, so the performance is more than sufficient, and a large amount of data calculations are still transmitted through the network interface, and most of them are calculated through the server.

Soon, Qi Na confirmed that the operating system of the manufacturer's robotic arm was also modified based on Linux through two commands.

This is too simple for Qi Na.

He exported the core file of the robotic arm, and then obtained the fragmented source file by decompiling.Jiner uploads all files to the server.

Facing the questions from colleagues who were talking in a hurry, he said: "Go and see the source document yourself, and I will go to retreat."

But this source document is just like a heavenly book. How can these fledgling young people have the patience to read on?
Qina returned to the office, locked the door, hung up all the phones and mobile phones, and then placed a page in the void, copied the operating system in the mechanical arm, and then used the intelligent brain to virtualize a mechanical arm, accompanied by After reading the source files, Qi Na began to analyze the system.

Combined with the technical development documents provided by the manufacturer, it took only two hours for Qi Na to understand the operation requirements of the robotic arm.

Qina felt that the 40 was not worth it.It's not that the machine is too rough, but that the software is too weak.

Then Qina started from scratch and wrote a new set of control software, using a simplified version of linux as the operating system.

This set of robotic arms has only a pair of crab-like pincers, which can only grip objects.However, there is enough space inside the robot arm to place wires and connectors.It would be a waste to use only one pair of crab hands like this.

Qi Na immediately began to plan the revision plan.

First, replace the crab pliers with finger-like joints, and then add three more joints to form a real manipulator.

However, this kind of mechanical finger has no force feedback and cannot obtain the state of the grasped object.

But this is not important, what needs to be done now is to modify the equipment.

When Qi Na left the office, as expected, all the R&D colleagues stayed behind, and Qi Na was secretly happy. The vigor of young people made the company full of vitality.

Qi Na cleared the firmware of the robotic arm, installed a simplified version of Linux at the same time, and then installed the control software he wrote for the robotic arm on the laptop associated with the robotic arm.

He moves very quickly, his hands are like a pianist, extremely fast and accurate, there are almost no mistakes or corrections, and the numbers and letters on the laptop screen fall like raindrops.

The college students who had just walked out of the school next to them were stunned, and some pretentious colleagues suddenly lost their arrogance, only thinking that they might not be able to achieve Qi Na's height in their entire lives.

His skill as a piano master has always been amazing, and he can't help conquering this group of young people in Qilin's Wings.

Qina would think of all kinds of whims and whims of the people around him. After entering the last command, press Enter to restart the mechanical arm.

I heard the creaking sound of the mechanical arm, trembled slightly, and the whole machine seemed to be alive. The red LED lights emitted in the joint gaps set off the arm like red jade. After all, it is a new machine with a piano-painted shell. Still kind of cool.

Qi Na immediately connected the database system used for the demonstration with the robotic arm on the spot, and at the same time shut down the virtual server modules one by one, and the fifteen virtual machines deployed were offline one by one.

The operating system and control software of the robotic arm he wrote have much lower requirements for data calculation with the background server, leaving only one server as a transfer station with the database.

According to the test process, Qina first sends a piece of information to the database. After the database gets the information, the control software of the robotic arm obtains the information synchronously, that is, the information of the objects grasped by the main robotic arm.

Qi Na did not use RFID technology for near-field identification, and did not plan to use Internet of Things technology. Instead, it started from scratch. Simply put, it wanted its own masterpiece, video recognition technology.

That is to say, a high-definition camera is installed on the robotic arm to identify the barcode on the express package.

This is not complicated to say, but it is not easy to implement.

First of all, it is necessary to ensure that there are barcodes on multiple sides of the package. This alone is already unattainable for most express companies.However, Qi Na has a way to deal with it, which is to ask the merchants who deliver the goods to operate.As for the effect, it can only be seen after effects.

Secondly, after the package arrives, it will not be square and square, and when the barcode is pasted, it will not be horizontal and vertical, which will also increase the difficulty of capturing the barcode with a high-definition camera.

Qi Na's solution to this problem is to add two cameras indoors for cross-calibration.

Finally, what to do with the barcode on the package if it gets wet from rain and wears out from handling?Qi Na's initial idea is to use the whole process of video surveillance on this system, and at the same time compare the batch barcode list, these two means to solve the problem package.

Of course, the last two belong to process design issues, and Qi Na has not started to write control modules and software.

All he has done now is to install a high-definition camera on the robotic arm for barcode recognition.

But that's okay, after all, it's the testing stage, every package is stacked neatly, and the barcode is also pasted horizontally and vertically on the side.

A message from Qi Na was sent to the database, and the robotic arm was raised almost at the same time, stretched within the radius of the crankshaft, hovered in front of the neatly stacked packages, and swung the rocker arm left and right, as if searching for the target package.

Packages that match the information were piled up at the bottom, and the robotic arm made a judgment almost in a breath. It carefully moved the top package away, but still neatly stacked it aside, and then grabbed the target package. Then rotate the crankshaft, the mechanical arm is almost 180 degrees, the heavy mechanical hand is like a martial arts master punching, the young people standing around startled and retreated, only Qi Na remained motionless, The mechanical arm stopped almost close to his cheek, let go of the crab pincers, and the package that Qina wanted to pick up fell on the table without making any abnormal noise, just like people face to face.

The colleagues surrounding Qi Na and the robotic arm were stunned, not only by Qi Na's demeanor, but also that the robotic arm test was almost perfectly completed.Some of them applauded first, and then all clapped and cheered enthusiastically.

Some shrewd people have realized that this little-known company they belong to will be a new legend.

Emily stood at the outermost edge, calm on the surface, but countless thoughts had been churning in her heart. She remembered the scene before the virtual fitting system went online with him when she was in NMC, and also remembered the same cheers and applause. When testing the virtual fitting system, the colleagues around me were so excited and excited, just like the young people around me now.

The phone she was holding took two videos and sent them to Jenny, titled The New Miracle.

Qi Na waved his hands at everyone, and said very dissatisfied: "Didn't you find the problem?"

Someone asked: "What's the problem?"

But someone quickly replied: "This is of limited use for large pliers."

Qina nodded: "I want to change the pliers into fingers tonight, can any of you help me?"

Although this question seemed simple, almost everyone was silent.

Qi Na pouted, he has great advantages in software, but in terms of hardware, he is somewhat lacking. If there is no hardware expert to assist him, it is almost impossible to transform the mechanical arm.At least ten days and a half months more.

At this time, a voice whispered in the corner of the R&D laboratory: "Can I try?"

So everyone turned their heads to look at this person. Qina was tall and tall, and quickly passed the backs of everyone to find him.

This is a skinny colleague who is only 1.6 meters tall. He looks older than other colleagues, but Qi Na remembers him.

"Xiao Gao, tell me!" Qi Na didn't remember any mention of his experience in robot manufacturing in his resume.

Gao Qinglin was a little shy, he didn't expect that Qi Na would remember his name, he was a little nervous, so he spoke quickly, and a little bit jumpy: "You can remove the shell, I heard it when they were doing the test, there are more The repair parts they left behind, after the shell is removed, there is enough space inside, the repair parts are enough for a finger to use, after the shell is removed, the main board and control interface inside are spare, just need to be reconfigured.”

All the colleagues in the audience frowned, but they almost understood what he meant, but they all felt that he was too disorganized, and what he said was scattered. If the reaction of the brain was slow, they would definitely think that he was talking to himself Talking nonsense to himself.

Qina nodded, and Gao Qinglin at least told what he was going to do. Although it was a little unreliable, he asked: "How do you know that there is enough space, and there are spare motherboards and control interfaces?"

After all, the manufacturer's engineers have never disassembled the equipment.How did Gao Qinglin know?

Gao Qinglin stammered a bit: "I'll set them up. They're from Cantonese. I can understand Cantonese. I know everything they say. After chatting a lot, I know everything."

Qi Na felt a little regretful, he originally thought that Gao Qinglin had some special skills, but he didn't expect that he had heard all of them.

However, Gao Qinglin said again: "I have participated in the National Robot Contest, and I am just a substitute. None of these things can trouble me."

Qi Na's eyes lit up, this is what he wanted to hear, no matter what, Gao Qinglin still has experience.
