Rule department scholar

For example, the number one student in the college entrance examination in other provinces is really a new face in the report. Zhao Yi's reputation is too great. The title of "genius mathematician" can compete with second-tier starlets. It has been reported in the past year many times.

Reporters are also more inclined to interview Zhao Yi, and the news they get can attract a lot of attention if they are posted online.

Zhao Yi still decided to keep a low profile.

After a few days of the top scorer in the college entrance examination, he basically stayed at home and was bored, and at most he went around the neighborhood to experience the relaxed and lazy life?

Mathematics is the most basic subject.

Even biological science has a lot to do with mathematics. There are many biological experimental analyzes that require the use of mathematical methods for analysis.

Early July.

Zhao Yi is about to end his easy life, and is going north to Yanhua University.

The day before? Lin Xiaoqing was at his home talking about her longing for college life.

It's getting late.

Thinking about what her mother said, Lin Xiaoqing stood up shyly, looked towards the balcony, and then asked seriously, "Are you back?"

Does she mean that Zhao Yi went to the capital? He is busy with robot-related matters, and he seems to be going abroad to attend an academic conference in August, and he seems to have no time to come back.

Zhao Yi also glanced towards the living room balcony.

There is a figure there.

Zhao Hongjuan.

After the college entrance examination ended, Lin Xudong and Zhao Hongjuan seemed to have made an agreement that Lin Xiaoqing was strictly forbidden to come to him after dark.

Every time Lin Xiaoqing was alone with him? There were always figures at the window.

Zhao Yi wanted to call the police!

Peep!

Considering that Lin Xudong is the captain of the criminal police, and it was his daughter who came here? Zhao Yi decided to be calm and sent Lin Xiaoqing to the door? He suddenly pushed her to the wall at the hanging corner.

Hey.

Can't see it?

Zhao Yi experienced Bidong's arrogance first, and then gave him an affectionate hug.

Lin Xiaoqing wanted to push him away, but didn't use much strength? Zhao Yi put her palm on the place with the most flesh? Then she gently hooked the tip of her little nose, and said with a smile on her face, "I promised to send you there school."

Lin Xiaoqing blushed and raised her head gently, "Then it's a deal!"

"Do not worry!"

"Then I'll go first..."

Zhao Yi didn't let go.

Lin Xiaoqing suddenly moved her head closer.

Before Zhao Yi could react, he felt a hard bite on his shoulder, and a low voice came from his ear, "When it's time, remember to call me."

After she finished speaking, she pushed Zhao Yi away, covered her face, opened the door and ran out.

"Sigh~~"

Zhao Yi squinted at the bitten shoulder, and sighed depressingly, "There is profit and there is compensation!"

"Hand, earned it."

"Shoulders, lost!"

"This girl really hurts when she bites..."

……

The testing time for the robot is July [-]th.

Zhao Yi arrived in the capital one week in advance, and went straight to Yanhua University after getting off the plane. There is still some work to be done before the test, and he needs to check the function in advance.

Since he decided to cooperate with Zhao Yi, Qian Zhijin has regarded the project as an important task of "building the reputation of the laboratory". Not only did three doctoral students and one graduate student follow Xu Chao to improve the code, but he himself is always concerned about the progress , spent a lot of thought on the robot.

These efforts are of course effective.

The robot's item recognition function, including the database for identifying products, has been improved a lot, the automatic pathfinding function has also been improved, and the appearance has also been greatly improved.

Compared with the previous robots, the only thing that is the same is the robot arm.

The Intelligence and Automation Lab has better partners who can provide more advanced robotic arms, but the original robotic arm involves a lot of code, and is even linked to the data of the program package. If you want to change it, you need to adjust a lot of code.

That would be a very complicated job, and maybe only Zhao Yi himself would be able to make the new mechanical arm work normally within a month.

In the end, it was agreed that the arm would not be replaced.

After Zhao Yi arrived at the laboratory, he was dragged by Qian Zhijin to a workshop. The workshop looked very technological, surrounded by more than a dozen computers in a circle, with a robot in the middle, and a large number of lines and equipment.

This scene is really taller, bigger, and higher than at home.

"The laboratory is a profession!"

Zhao Yi made a silent comment in his heart, and was still very calm on the surface, listening to Qian Zhijin's introduction of the design progress.

Now the robot still has some small problems that need to be corrected, and at the same time, there is a big problem that has not been solved, which is the follow-up method of the robot to judge the "human obstacle".

This link is mainly about the stress response of the robot when it may collide with the human body.

Human activities are fluid.

Normal people go shopping in the supermarket, and there are people shopping next to them. It doesn’t matter. When a collision may occur, just react and dodge it. Even if you can’t dodge, just touch it.

The robot is made of pure metal, and there are many precision parts inside. After colliding with the human body, the result may be very serious. It may injure people, or it may be directly damaged.

Then the stress response is very important.

The design plan discussed by Qian Zhijin and Xu Chao is that if someone approaches a certain range, the robot will stop operating. However, considering the flow of people in the supermarket, the effect of stopping the operation is very poor, and the robot may stop for a long time.

In addition, it is not easy to stop the design of the operation, and the frequent stop can easily cause damage to the hardware and software.

They can only continue to consider the plan.

"Actually, the best solution is to set an operating speed, just like the human body. When someone gets too close, the robot's arm can be slowed down. Otherwise, it will return to normal speed, but the speed setting The setting is very complicated, and the calculation of the judgment mechanism is also very complicated..."

"There will be some other issues involved, and the underlying package may need to be improved..."

Qian Zhijin and Zhao Yi were talking.

Xu Chao and a few fresh students stood beside them, and they also said, "It's really too difficult. We want to design such a support program, and it will take at least a month or more!"

"There is not enough time now!"

"I still suggest to stop the operation and let the robot test. Anyway, no one will really get close to it during the test."

"What if there is an accident? It suddenly stopped working, and the robot stopped working."

"Otherwise, the stress function of the human body will be removed. Our test location is the supermarket on the first floor of the shopping mall. We can discuss with them and clear up a place..."

"..."

Several people kept talking.

Zhao Yi has been listening patiently, almost meaning is 'difficult', 'difficult', 'difficult'.

He simply said, "Well, let me see!" He asked Xu Chao, "Which computer has all the program packages? All the codes?"

Xu Chao pointed to a computer on the left.

Which computer's mainframe is not closed, the main board is directly exposed, and the model of each accessory seems to be larger. Qian Zhijin introduced, "It was removed from the server room and installed directly."

"Ah."

Zhao Yi nodded and opened the programming software and database, found the program package, code and data, and also found the half-designed shutdown program.

The stop program on the computer can be said to be just a command to stop the robot arm directly and block the robot's wheels at the same time.

The additional codes are to close this and close that, which is a protection mechanism for the robot software and hardware.

Zhao Yi took out the paper and pen, made calculations on the scratch paper, designed a simple speed-down curve, and then began to tap the keyboard continuously.

Lines of code are typed.

At the very beginning, only Qian Zhijin and Xu Chao were watching, and at some point, people from the workshop came over, and they squeezed to look at the computer screen.

Zhao Yi used a scientific research coin and a learning coin to improve his inspiration and keep his concentration unaffected, so he kept tapping on the code.

There was a doctoral student behind him who couldn't help but take a deep breath. He found that his thinking couldn't speed up typing codes at all.

The same goes for everyone else.

Qian Zhijin's thinking couldn't keep up, and he couldn't understand the following at all, but he still pretended to understand, and turned his head to remind, "Shh~"

"Don't make a sound!"

"Mr. Qian, can you understand?" A doctoral student couldn't help asking in a low voice.

Qian Zhijin raised his head and said, "Of course, now he is directly applying the speed curve on the straw paper to the program to control the robotic arm!"

A few people next to him nodded, feeling a little disdainful in their hearts.

Several of them are students under Qian Zhijin's supervision, and they have been teaching them for a long time. They think Qian Zhijin is a good teacher, but their ability is definitely not as good as that of the other two professors in the laboratory.

Qian Zhijin is a very face-saving person, and pretending to understand is normal operation.

For example, now.

Everyone knows that Zhao Yi is using the speed curve and design code on the straw paper to control the mechanical arm?

Needless to say!

The key is how the code is designed as a whole, and none of them can keep up with it.

45 minute later.

Zhao Yi stopped tapping the keyboard, pressed his sour fingers, and said, "Brother Chao, help me make a cup of coffee!"

"Correct!"

Qian Zhijin quickly reacted, "Don't let Xu Chao go, Xiao Zhou, you go!"

Xiao Zhou hurried to go.

Zhao Yi sat in front of the computer and waited. When the coffee was brought over, he stood up and stretched, took a big sip of the coffee, and then said, "It's done!"

"nailed it?"

Everyone felt unbelievable, they thought it was Zhao Yi's 'half-time break', not even half-time, because less than an hour had passed.

Their entire team has spent a week thinking about the stress design of the robotic arm, but they still haven't come up with a good solution.

This……

is it possible?

Qian Zhijin quickly sat down in front of the computer and carefully looked at the code line by line. What he was looking for was the place where he couldn't keep up with the train of thought just now, and soon he chose to give up.

45 minutes.

Zhao Yi tapped almost [-] lines of code, and his fingers never stopped. If you want to understand all the [-] lines of algorithms and control codes, it will take time...

Is one day enough?

Qian Zhijin thinks it should be multiplied by three, or even seven?

uncertain.

Finally, Qian Zhijin nodded and stood up, and commented, "The design is very good, as expected of a computer genius and algorithm expert!"

"Mr. Qian, can you tell us something?" Xiao Zhou, who had gone to make coffee just now, asked with a smile on his face. He obviously did it on purpose, and everyone else was holding back their laughter.

Qian Zhijin said seriously, "What are you talking about? The important thing now is not to learn, but to test the effect. Xiao Zhou, it's up to you. Come and debug and run it. After the debugging is passed, you can put it into the robot program for a try. "

The code written by Zhao Yi is not 100% accurate, there may be many typing errors, and there may be inconsistencies between programs and programs.

These are minor issues.

The code still needs to be run and debugged in order for the robot test to work.

Zhao Yi considers himself an 'error-correcting expert', but he doesn't want to do things that the team can do, and he wants to give others a chance to do it.

So he walked straight out of the lab and was taken to rest by a doctoral student.

Qian Zhijin arranged for him to live in the teacher's dormitory building in the school. There is an empty room on the second floor. The area is not large and the decoration is not gorgeous, but it is very good to live in such a single room in the school. Well done.
