The March breeze brought the spring chill across the provincial campus, along the corridor of the Science and Technology Center, and into the electromechanical laboratory on the third floor of the Activity Center.
The laboratory is quite large, about 80 square meters. Facing the door is a workbench consisting of four large desks. There are seven or eight desks beside it. The desks are filled with various equipment, tools, electronic components and circuits.
plate.
Behind the laboratory is a spacious space of about fifty 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 at the workbench, and everyone was looking at the notebook in front of them seriously.
The picture on the laptop is a video from a blogger in the technology district. In the video, a robotic arm is holding a table tennis racket and skillfully hitting a table tennis ball against the wall.
After watching the video, captain Li Dongsheng looked at the young team member sitting furthest away and asked: "What major? How is your hands-on ability? Do you have experience in robotics? Are you good or bad?"
"Uh...he's my roommate."
"Oh..." Li Dongsheng immediately became a little disappointed: "You're a freshman?"
At this time, the only girl laughed: "Captain, it would be great if a new person comes in. Are you still choosing?"
Li Dongsheng also burst out laughing: "I'm worried. We accept everyone who comes, regardless of education or distinction - Xuanxuan, hurry up and urge your bestie, we can't do without a chief financial officer!"
The girl named Xuanxuan laughed and took out her mobile phone.
Li Dongsheng coughed and said to the other boys: "I just watched the video again. The author's robotic arm is in the same direction as our robot. Do you have any opinions?"
As soon as they heard this, the team members began to look at their noses and minds.
the reason is simple……
The video they watched, the author...
too strong!
——"It took me a month to build a robotic arm that can play table tennis"
Listen, is this human talk?
The arrogant title must bring a lot of traffic. In addition, the author does use fast-forward to show a robotic arm from design to completion, and finally completes the task of playing table tennis...
Therefore, in just one week, the number of views of this video exceeded one million.
When no one spoke, the vice-captain in charge of the mechanical department coughed lightly: "Ahem...Captain, I think what a netizen said is right."
"Which sentence?" Li Dongsheng lowered his head and looked at the video comment area.
The comment section was full of praise.
"It can be seen that table tennis is indeed a national sport."
“I can’t understand it, but I’m shocked”
"Hopefully it's not a cyber thimble"
"Roll it up! Technology Zone UP, roll it up!" This person 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 such a robotic arm that can automatically receive serves and can also be controlled synchronously.
A team of five people can't even think about it for three or two months.
Of course... the premise is to build it from scratch, from design to source code to assembly to debugging.
Therefore, many netizens suspect that this is not the work of one person.
The reason for choosing such a title is simply to create a persona of a "technological genius".
In this modern world where traffic is at the forefront, what else is new?

Ye Ming walked on campus holding his mobile phone.
Even wearing a mask, he couldn't hide the smile on his face.
He is having fun.
As a cute new UP owner, his debut video reached one million views within a week.
In the science and technology district, without selling meat or taking advantage of hot spots, this is already a ridiculous start.
Of course, the reason why the video is so popular is not only that the robotic arm in the video itself has sufficient technical content, but also that his video is very controversial.
Not only did he not show his face in the entire video, but even his voice was artificially synthesized by AI - so much so that at first, the audience was convinced that he was a marketing account and that the video was stolen from a "foreign master".
Later, after confirming that his video was original, someone soon compared him with the robotic arm of another UP owner in the technology area...
So naturally, the video became very popular.
The number of his fans has also exceeded five digits from single digits.
According to this rate of increase in fans, I'm afraid it won't take more than two months for me to have a smooth meal, right?
"Brother, be careful."
Just when Ye Ming was playing hard, he almost hit the glass door of the library - if there wasn't a buddy behind him who pulled him away.
"Um...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 quite a wealth of science and engineering books, and Ye Ming found his goal easily.
A copy of "Programming Essentials" by Alexaepanov/Paul Mes.
A copy of "Matrix Computation" by Gene H. Golub and Charles F. Van Loan.
These two books are well-known in the fields of algorithms and artificial intelligence, and can be regarded as textbook-level readings for graduate students in related majors.
As a "fresh" student, the reason why Ye Ming understands it is naturally because...
He's hung up.
…
Holding the book in his arms, Ye Ming scanned the entire place and found that the entire second floor was already overcrowded, especially the single seats next to the bookshelf, where there were no empty seats.
Just when he was filled with disappointment and was about to go to the cafeteria to make do, the girl sitting next to him suddenly picked up her cell phone.
Ye Ming remained calm and glanced at the girl secretly - according to experience, as long as he takes the mobile phone, he plans to leave.
The girl clicked on WeChat and saw a text message.
——Dear Xiao, come quickly, I’m waiting for you.
The girl smiled softly and quickly typed a reply.
——Wait a moment, I already have an idea for the last question.
After replying to the message, the girl turned off her phone and continued to do the questions.
Ye Ming withdrew his gaze with satisfaction.
really!
My boyfriend is urging me here, and it seems to be another relatively simple postgraduate entrance examination question in Mathematics. I guess this senior will give up her seat in a few minutes, right?
But as time passed by, Ye Ming found that the girl's brows gradually wrinkled and the pen in her hand gradually stopped.
At this moment, a girl opposite who was wearing a yellow coat, a silk scarf, and a gel pen in her hair glanced at Ye Ming warily, and then she touched the fallen girl.
Problem girl.
The girl looked up and immediately felt Ye Ming's gaze.
Obviously, she had realized that Ye Ming had been standing beside her for a long time.
Ye Ming coughed lightly and whispered: "r(AT A)=r(A)"
"What?"
"The orthogonal transformation method converts the quadratic form into the standard form. The key is r(AT A)=r(A), and then solve three linear homogeneous equations..."
Ye Ming whispered softly, looking at the pencil in the girl's hand.
The girl's face was full of astonishment, but she immediately realized that Ye Ming was lecturing for her. She blushed immediately, handed the pencil and scratch paper to Ye Ming, and stood up at the same time.
Ye Ming is not polite either. Anyway, he has been coveting this seat for a long time.
"After obtaining the eigenvectors, unitize them to obtain the orthogonal matrix..."
Ye Ming took the pen and quickly wrote down the process: "The method you used is difficult to calculate the determinant. After calculation, you have to factor it... it's troublesome."
girl:"……"
Ye Ming wrote down the answer to the second question.
"2y1^2+6y2^2"
The girl took the manuscript paper at a loss and held it for a long time before whispering: "Thank you, senior brother."
"You're welcome." Ye Ming waved his hand and whispered: "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 up her things and left, Ye Ming also opened "Matrix Calculation".
Then, he lowered his gaze and called softly in his heart.
