From black technology to super engineering

Chapter 1 Let the bullets fly for a while
In the spring of 2022, the provincial capital.

"Who is Ye Ming?"

The March breeze brought the spring cold across the campus of the Provincial Jiaotong University, along the corridor of the science and technology center, and blown into the electromechanical laboratory on the third floor of the activity center.

The laboratory is quite large, about [-] square meters. Facing the gate is a workbench composed of four large desks. There are seven or eight desks on the side. The desks are full of various equipment, tools, electronic components and circuits. plate.

Behind the laboratory is a spacious space of about [-] square meters, with two generator-like mechanical equipment stacked on the floor.

This is the "dedicated" laboratory of the provincial Jiaotong University robot team.

At this time, seven men and one woman were sitting by the workbench, and everyone was seriously looking at the notebook in front of them.

The screen of the notebook is a video of a blogger in the science and technology area.In the video, a robotic arm is holding a ping pong racket, skillfully hitting a ping pong ball against the wall.

After watching the video, Captain Li Dongsheng looked at the young team member who was sitting farthest away and asked, "What kind of professional? How good is your hands-on ability? Do you have experience in robotics? Are you good?"

"Uh...it's my roommate."

"Oh..." Li Dongsheng immediately became a little disappointed: "A freshman?"

At this time, the only girl laughed: "Captain, it would be great if there is a newcomer, why don't you choose?"

Li Dongsheng also burst out laughing: "I'm the one who is in a hurry. We don't refuse anyone who comes, and there's no one to teach——Xuanxuan, hurry up and remind your best friend, we can't live without a chief financial officer!"

The girl named Xuanxuan chuckled and took out her phone.

Li Dongsheng coughed and looked at the other boys: "I watched the video again just now, and the author's robotic arm is in the same direction as our robot. Do you have any opinions?"

Upon hearing this, the team members all looked at each other with their eyes and noses, and their hearts became concerned.

the reason is simple……

The video they watched, the author...

too!powerful!up!
—— "I spent a month building a robotic arm that can play table tennis"

Listen, is this human?

The arrogant title must have a lot of traffic. In addition, the author did use fast-forward to show a robotic arm from design to completion, and finally completed the task of playing table tennis...

So in just one week, the number of views of this video exceeded one million.

Seeing that no one spoke, the vice-captain in charge of the mechanical part coughed lightly: "Cough...Captain, I think the words of a netizen are good."

"Which sentence?" Li Dongsheng looked down at the video comment area.

The comment section is full of praise.

"It can be seen that table tennis is indeed a national sport"

"I don't understand it, but I'm shocked"

"Hope it's not a cyberthimble"

"Roll it up! Technology zone UP roll it up!" By the way, this guy also @several other well-known bloggers in the technology zone.

……

The deputy captain smiled: "Let the bullets fly for a while."

——They are engaged in intelligent robots and robotic arms. They don't know much about the technology and engineering required for this kind of robotic arm that can automatically receive and serve and can also be controlled synchronously.

A five-person team can't even think about it in three or two months.

Of course... the premise is to do it from scratch, from design to source code to assembly to debugging.

Therefore, many netizens suspect that this is not the result of one person.

The reason for taking such a title is nothing more than to create a "technical genius" personality.

In the modern age of traffic, what else is new?

***
Ye Ming walked around the campus holding his mobile phone.

Even wearing a mask, he couldn't hide the smile on his face.

He is yelling.

As a cute new UP host, his debut video reached one million views within a week.

In the technology zone, without selling meat or gossiping about hot spots, this is already a ridiculous start.

Of course, the reason why the video is so popular is not only that the mechanical arm in the video has sufficient technical content, but also because his video is very controversial.

Not only did he not show his face in the video, even the voice of the copywriting was synthesized by AI—so much so that at the beginning, the audience even firmly believed that he was a marketing account and that the video was stolen from the "foreign master".

Later, after confirming that his video was original, someone soon compared him with the mechanical arm of another UP master in the technology area...

So naturally, the popularity of the video rose.

The number of his fans also broke through five digits from single digits.

According to the speed of increasing fans, I am afraid that within two months, I will be able to make a meal smoothly, right?
"Brother, be careful."

Just when Ye Ming was squatting, he almost bumped into the glass door of the library - if it wasn't for a buddy behind him to give him a hand.

"Uh...thank you."

Ye Ming blushed, thanked him and walked quickly to the second floor of the library.

As a university of science and engineering, the provincial Jiaotong University library has a lot of science and engineering books, and Ye Ming found his goal easily.

A copy of "The Originals of Programming" by Alexander Stepanov/Paul McJones.

A copy of "Matrix Computation" by Gene H. Golub and Charles F. Van Loan.

These two books are well-known in the field of algorithms and artificial intelligence, and they can be regarded as textbook-level readings for graduate students of related majors.

And as a "new" freshman, the reason why Ye Ming can understand it is naturally because...

He has hung.

……

Holding the book in his arms, Ye Ming glanced across the room and found that the entire second floor was overcrowded, especially the single seat next to the bookshelf, and there was no empty seat.

Just when he was full of disappointment and was about to go to the cafeteria to make do with it, the girl sitting next to him suddenly picked up the phone.

Ye Ming kept his composure and secretly aimed at the girl—according to experience, whenever he took his mobile phone, he planned to leave.

The girl clicked on WeChat, and it was a text message.

——Dear Xiao, come quickly, I'll be waiting for you.

The girl smiled lightly and quickly typed a reply.

——Wait a minute, the last question, I already have an idea.

After answering the message, the girl turned off her phone and continued to do the questions.

Ye Ming looked back with satisfaction.

really!

There is a boyfriend urging here, and it seems to be a relatively simple math three-entry exam question. I guess this senior will give up in a few minutes, right?

But as time passed, Ye Ming found that the girl's brows gradually frowned, and the pen in her hand gradually stopped.

At this moment, a girl opposite, wearing a yellow coat, a silk scarf, and a handsome gel pen stuck in her hair, glanced at Ye Ming vigilantly, and then she touched the girl who was stuck Problem girl.

The girl looked up, and immediately felt Ye Ming's gaze.

Obviously, she has realized that Ye Ming has been standing by her side for a long time.

Ye Ming coughed lightly, and whispered: "r(AT A)=r(A)"

"what?"

"The quadratic form is transformed into the standard form by the orthogonal transformation method, the key is r(AT A)=r(A), and then three linear homogeneous equations are solved..."

Ye Ming said softly, looking at the pencil in the girl's hand.

The girl was stunned, but in an instant she realized that Ye Ming was speaking for her.She blushed immediately, and immediately handed the pencil and draft paper to Ye Ming, and stood up at the same time.

Ye Ming is also welcome, anyway, he has coveted this seat for a long time.

"After obtaining the eigenvectors, normalize to obtain an orthogonal matrix..."

Ye Ming took a pen and quickly wrote down the process: "The method you use, the determinant is difficult to calculate, and it needs to be factored after calculation... Trouble."

girl:"……"

Ye Ming wrote down the answer to the second question.

“2y1^2+6y2^2”

The girl took the manuscript paper in a daze, held it back for a long time before whispering: "Thank you, brother."

"You're welcome." Ye Ming waved his hand and said in a low voice, "Do you still need this position?"

"Yeah? No need."

"Thank you." Ye Ming took the book out of his lap and put it on the table.

girl:"……"

As the girl hurriedly packed her things and left, Ye Ming also opened "Matrix Computing".

Then, he lowered his eyes and called softly in his heart.

"system"

　The black technology involved in this book contains a lot of nonsense in a serious manner, so you can enjoy it.
