Ye Ming took over the remote sensing controller changed from Xbox one, and quickly became familiar with the operation under Peng Xiaofei's introduction.

"The remote sensing module is not bad, who tuned it?"

"The captain is in charge."

Ye Ming glanced back at the captain Li Dongsheng, and saw that Li Dongsheng and Jiang Yongliang, the deputy captain in charge of structural design, were seriously discussing something in front of their notebooks.

Peng Xiaofei said with a smile: "This is also the only advantage of our robots, but the RC competition is now more and more inclined to be fully automated, unlike the Mecha Masters Tournament, which eats remote sensing and operation, and Captain Li's technology is buried." ”

Ye Ming nodded: "Hmm...... But if you have technology, you are not afraid of anything, aren't we here to learn? ”

"Having said that, I still want to win an award for Baoyan." Peng Xiaofei was a little emotional and a little depressed.

He is Ye Ming's roommate, although he has only been together for half a year, he also knows that Ye Ming has turned on the "Xueba" mode since the middle of last semester - the game is not played, the novel is not read, and even the small movie is not touched, and he runs to the library and study room every day, and he is stunned to learn the feeling of being a senior in high school.

As long as Ye Ming's learning state is maintained, it is a sure thing to protect the research.

But he is different, and it doesn't mean that he Peng Xiaofei is worse than Ye Ming - everyone is in the same school based on their college entrance examination scores, how much worse can they be?

He just thinks that if he is in college, it will be really boring if he still does the same as the third year of high school.

It can only be said that everyone chooses to spend their college career in a different way.

At this time, Li Dongsheng beckoned to the two.

……

"We don't have a lot of people on our team." Li Dongsheng looked at Ye Ming with a smile: "Ye Ming, you just said that you plan to fix a software project, so did you learn Python in advance?" ”

"Learned." Ye Ming was not modest, but nodded directly: "C, C++, Python will all be a little." ”

Li Dongsheng was obviously happy: "Okay, then the two of us will get a computer." Xiaofei, you and Tao Zheng are working together on the lower computer, and by the way, you are responsible for the control, no problem, right? ”

Ye Ming and Peng Xiaofei glanced at each other, and both nodded at the same time.

The so-called host computer refers to a computer that can directly issue control commands, such as a personal computer. The lower computer is a system that executes commands, such as PLC, single-chip microcomputer, etc.

For example, if a computer is connected to a printer, then the computer is the upper computer, and the main control chip system of the printer is the lower computer.

The upper computer in the team is naturally the notebook in everyone's hand, and the lower computer is the robot's STM32 microcontroller.

"Ye Ming, while I have some time, I'll introduce you."

Because Ye Ming didn't bring a notebook over, Li Dongsheng pulled him to his notebook and sat down: "I saw you and Xiaofei try our robot just now, can you understand what is wrong with our robot?" ”

Li Dongsheng asked, but found that Ye Ming hadn't answered for a long time, he turned his head suspiciously, only to see Ye Ming staring at his screen, with a rather strange expression on his face.

- On his screen, a frame of "I spent a month making a robotic arm that can play table tennis" is suspended.

This screen is the source code interface of Python.

"Haven't you seen this video?" Li Dongsheng asked curiously.

"Forehead......" Ye Ming endured his complicated mood and nodded honestly: "I've seen ......"

It took him a day to cut out this video! And it was cut to extreme shreds......

"Captain, I think there may be two problems with our robots, one is that the visual robustness is low, and the other is that the obstacle crossing function is not good." In order to prevent Li Dongsheng from asking about the content of the video again, Ye Ming hurriedly replied.

Robustness, in fact, is the transliteration of Robust - but in the field of robotics, it does not refer to how solid the robot is, but to the ability to resist interference and unexpected situations.

Low visual robustness means that the robot will not be able to make accurate judgments if there is interference from other objects, resulting in mission failure.

Syllable! Li Dongsheng slapped his thigh: "Not bad!" That's it! That's why I want to see the solution of Brother Trumpet. As he spoke, Li Dongsheng also looked at the computer screen.

- Brother Trumpet, this is the nickname given by netizens to the author of "I Made a Robotic Arm That Can Play Table Tennis in a Month", because this guy's name is very happy.

It's called "Tick Tick Tick".

"It's a pity, this guy said open source, but he didn't move at all, and he didn't even post any news." Li Dongsheng's face was full of regret.

Ye Ming's eyes widened when he heard this.

Affection...... Is this waiting for yourself?

At this time, the voice of the deputy captain Jiang Yongliang sounded next to him: "Captain, I don't think about it, you look at it." ”

Ye Ming and Li Dongsheng turned their heads at the same time: "What's wrong with Zhihu?" ”

"Brother Trumpet is on the hot list."

……

……

Zhihu, a Q&A platform for sharing knowledge. Due to the emergence of a large number of "annual income of one million", "I am in New York, just got off the plane", "I am in the top 3 universities", "I am in the top 500" and so on...... So he was jokingly called Bhu.

Pack B of B.

Ye Ming also has it on his phone, but he hasn't opened it for a long time.

clicked on the hot list and slid down a few times, a "How do you think of the robotic arm work of the author of Station B's 'Tick Tick Tick'?" Compared to the genius boy, who is a little more powerful? The question came into view.

Ye Ming felt that his face was hot, and he hurriedly took his mobile phone and walked aside.

This question has only been on the hot search for a short time, and there are only dozens of answers, but the highest-ranked answer has already had hundreds of likes.

"What do you look at? Look with your eyes.

Looking at the video, the author claims to have spent a month independently completing a six-axis robotic arm. Don't show your face throughout the whole process, don't talk about it without dubbing, I'm shy about him. But whether it is the design of the PCB, or the code or the code, there is no process, just the display of the finished product.

Of course, he didn't forget to take a picture of the machining.

But the question is, does the robotic arm need machining capabilities?

said that the cyber thimble has raised him, and the low-profile version is handmade.

This year, I don't act anymore. ”

Ye Ming took a deep breath, his heart began to beat faster, and at the same time clicked on the comment that should be answered.

Not surprisingly, there were more than 20 replies, all of which were in support of the respondent.

He gritted his teeth and continued to slide to the next answer.

"Interest-related, a former member of the RC team of a 985 school, responsible for the electronic control part.

Maybe everyone has no concept of the function of 'robotic arm playing table tennis',Let's put it this way,According to the accuracy and ability shown in the video,Replace table tennis with badminton,Then it is the brightest boy in the 2015 National Robot TV Competition - 2015year,The badminton robot of the University of Electronic Science and Technology is also used with human eye binocular vision,A strong batch,And then swept thousands of troops。

But be warned, Denko's robot is not a robotic arm with six degrees of freedom! That's just an automatic program-controlled car with a three-axle robotic arm on it to swing the racket!

Therefore, I do not believe that the author can independently complete it in such a short period of time, and can surpass the robotic arm of the badminton robot in terms of comprehensiveness. ”

……

"Look, I was right, right?" Vice captain Jiang Yongliang saw that Li Dongsheng also clicked on the Zhihu page, put the back of the chair on the side and smiled: "I said let the bullets fly for a while." ”

Li Dongsheng frowned, and after a few seconds of silence, he let out a long breath.

As a junior, he also mixes up Zhihu, and he also knows that it is not credible to pretend to be forced on Zhihu, but it is ......

Generally, there are two brushes.

In particular, a few of the highly praised ones are also sprayed with reasonable evidence.

He is also a member of the old RC team who has been playing since his freshman year, and now he has taken over the responsibility of captain, so he naturally knows how much work is needed for what function.

Take the big guy who made the robotic arm at station B as an example, although he used his spare time, he did it for four months before and after - don't think that four months of spare time is not as good as a month of concentrated time, sometimes doing projects and debugging all need inspiration.

Not to mention machining, boarding, and procurement, all of which require hard waiting time.

Therefore, Li Dongsheng also felt that that little brother could not have made it by one person, at least the relevant algorithms and codes would not be original to him.

Otherwise, why did he say that the open source would not be opened?

"Well, it's okay, if we can't learn from it, we'll do it ourselves." Li Dongsheng quickly laughed, glanced at the time and stood up: "Let's go, let's have dinner first!" ”

As a captain, of course, he has to show a lot of fighting spirit.

Just then, a voice suddenly sounded.

"Captain, leave the visual positioning and motion trajectory prediction algorithm of the ball-throwing robot to me."

Li Dongsheng turned around and saw Ye Ming holding his mobile phone and slowly walked over.

His face was a little red.

"Are you okay?"

Jiang Yongliang looked at this newcomer who had only joined for less than half a day, with a puzzled expression.

Although I know that this guy has the ability to teach math problems to junior seniors, this ability to "be a problem solver in a small town" is really nothing in the field of engineering.

"I want to ...... I should be able to do it. Ye Ming exhaled deeply and exhaled slowly.

Seeing that everyone was looking at him at this moment, he was suddenly a little nervous.

"The little brother you guys are talking about making robotic arms...... It's me. ”

- He came to the robot team, in addition to the mission, but also to use the resources in the team.

For example, the 3D printer on the side, as well as a series of tools and instruments.

Besides, the table tennis robotic arm was originally made by him.

From design to code, from machining to assembly grinding.

At his home, he originally started a machining workshop in the town!

Even without a system, he learned to turn screws three years ago!

What did he dare not admit?
