From black technology to super engineering

Chapter 32 Video is born like this
"The grapes are here!"

Before Peng Xiaofei arrived, his voice came first.

Then he returned to the lab empty-handed.Under Ye Ming's surprised eyes, he took out a few grapes from his pocket.

"Now the price is so high that the grapes are sold by the piece?"

"Hey, it's not for eating anyway, so I went to the cafeteria and asked for a few."

"I didn't see it, you're an expert at saving money." Ye Ming smiled and handed him the phone, while he went to the toolbox next to him to rummage for a while, and found an aluminum strip that was as long as a little finger.

"Be careful not to take pictures of me, and then help me think of lines."

"I was thinking about it on the way." Peng Xiaofei turned on the phone camera and pointed it at the top of the robotic arm.

Under the camera of the mobile phone, Ye Ming replaced the jaws, then fixed the aluminum bar, and then fixed the cutter head on the base.

Peng Xiaofei on the side cleared his throat: "I want to sew needles for grapes. As a boy, what should I do if I don't have needles? It's okay, let's drive by ourselves. In addition to fine movements, the mechanical arm can also cooperate with the motor in the front joint to complete it." Operation of various machine tools."

"For example, now I plan to use an aluminum strip to process it into a needle for sewing grapes."

Ye Ming gave him a thumbs up: "Good match."

"necessary."

As Ye Ming aligned the robotic arm with the cutter head, Peng Xiaofei said again: "We know that the melting point of aluminum is not high, and its hardness is not high, but there is no way, our motor torque is too small, we can only cut it --is not it?"

Ye Ming laughed beside him: "Yes."

As the two of them sang together, Ye Ming activated the mechanical arm.

The gripper of the mechanical arm began to rotate rapidly, and slowly stretched towards the cutter head.

"We saw that aluminum scraps were flying, and a needle with a diameter of about 0.5 mm was being rapidly formed... Fuck, slow down, it will break."

I have to say that it is indeed much faster for two people to work than one person.

And Peng Xiaofei, as the operator of the RC team, his hands are not usually stable, and the effect of the video shot is the same as that of a stabilizer.

"Another advantage of the aluminum needle is that it is easy to perforate. Please pay attention."

Peng Xiaofei held up his mobile phone and pointed it at the aluminum needle at the end of the robotic arm: "It's time to reflect the visual positioning accuracy of the robotic arm."

Following his voice, Ye Ming clicked the mouse cautiously.

The robotic arm precisely inserted a steel needle into the tail of the aluminum needle.

"The following is threading, and this is another moment to witness a miracle."

"The following is the moment to truly witness the miracle."

"Fuck, why did you sew too much?"

"The force feedback is too small, let me adjust it..."

Time passed minute by minute.

When the grapes were sewn, it was already evening.

In the laboratory, apart from Peng Xiaofei, there were two more people, Li Dongsheng and Tao Zheng.

The two also heard Peng Xiaofei say that Ye Ming was shooting a video, so they rushed over to watch the fun.

"Okay, what we see next is the ultimate challenge. 3D stereoscopic carving!"

Following Peng Xiaofei's voice, the robotic arm that had been replaced with a three-dimensional knife slowly stretched out to the rotating base in front.

Sawdust flying.

Right under everyone's eyes, the prototype of a robot cat, Tinker Bell, slowly appeared.

……

The hum of the motor slowly fades away.

Followed by the applause of Li Dongsheng and Tao Zheng.

"It's amazing." Li Dongsheng stared at the robotic arm with envy on his face: "Whoever has such a machine at home will not have to worry about it."

Tao Zheng also deeply agreed: "Ye Ming, according to me, you should use it to participate in Daiso or Internet+, maybe some investors will take a fancy to it, and then invest in you to start a business and become a boss."

Peng Xiaofei disagreed: "Forget it, Ye Ming is all open source. Besides, if it really wants to be commercialized, I don't think it can compare to those manufacturers that specialize in high-end robotic arms."

"Well, it really can't compare." Ye Ming was also very calm: "This is originally used for practicing hands. It's fine for playing tricks, but it's really not good enough to be used as a tool."

Li Dongsheng and Tao Zheng smiled at the same time.

Think about it, people have this technology, wouldn't it be easy to find a big manufacturer in the industry with this robotic arm?Why do you want to start a business? It's not the good time a few years ago.

Afterwards, several people gathered together to watch Ye Ming's video clip.

——They are indeed a little curious about how a video with two million views was born.

But after seeing it, they were disappointed.

Ye Ming used the most common video editing software. He first selected the highlights, and then put them together casually—the kind that didn't even have transition effects.

After the video is merged, he separates the audio track, and then writes lines according to the length of the video.

It's just that many of the lines this time came from Peng Xiaofei's impromptu performance on the spot.

In the end, he used AI voice to convert the lines into audio files, and then merged them into the video, and he was done.

And when all this was done, the time came to ten o'clock.

Everyone was dumbfounded when they saw the notification that the upload was complete.

"that's it?"

"if not?"

"I heard that to make a video, people want to be creative, do this and that, and also set up a studio... and the cycle is a long time." Li Dongsheng's face was full of emotion: "You are good, you can do it in one day. "

Peng Xiaofei laughed loudly: "This is the power of technology."

……

……

The sixth floor of the Science and Technology Museum.

RM preparation hall.

The RM mech master team is preparing for the competition intensely.

At the end of last month, they successfully won the first qualifying round of the college league, and will continue to participate in the cup after a two-month break.

It stands to reason that they don't need to stay up all night like this.

But...they had to suffer.

Because they changed the machine vision algorithm.

One and a half months ago, after they were "bloodbathed" by the RC team, they began to "strive for strength", which specifically manifested in looking for excellent open source algorithms all over the world.

For example, the machine vision of the trumpet brother is also one of their goals.

As a human, you always have to realize the gap before you know how to work hard.From this point of view, it is better for them to be bloodbathed by non-opponent RC than to be bloodbathed by other opponents in the final and semi-finals.

Cao Junwen and Gao He, the algorithm master of the team, were sitting cross-legged on the edge of the field.

Gao He checked the code intently, thinking about how to adjust the small parameters.

Cao Junwen, on the other hand, swiped his phone rather bored.

Suddenly, he was slightly taken aback.Immediately yelled.

"Damn it, brother trumpet has been updated!"

The teammates around the field who were practicing manipulation looked up blankly.

"Brother Trumpet! Tick-tick-tick!" Cao Junwen said loudly, "The one with the mechanical arm!"

"What's the matter with the update? Are you his fan?" one of the team members in charge of controlling the robot asked with some disapproval.

"Crap, nonsense! You don't know how strong this B is! And we use his algorithm!"

Cao Junwen suppressed his excitement and took a deep breath.

Started watching the video.

Ten minutes later, the video was over.

Algorithm master Gao He directly opened the GitHub account page of Brother Xiaohao.

——Brother Trumpet said he has updated the algorithm.
