Zhang Yuan opened the seafood noodles and planned to fill his stomach first.

Unexpectedly, the man opposite smelled the food and the Adam's apple couldn't help but thrust.

"Do you want to share half of you?"

"Ah, thank you! I have been deciding which baby to take on the road, but I forgot to eat."

After a meal, the two quickly became familiar with each other.

This guy is named Ye Kaifu, and his education is the same as his, he is just an undergraduate.

But the most important thing is that he is a "level eight fitter" who is proficient in the manufacturing of various handicrafts.

Zhang Yuan was curious now: "It's the kind of profession that... can be used to file a iron ball?"

A level eight fitter, I wonder how much salary is?

Needless to say, it must be taller than him!

"It is not to file a ball, but to use basic tools, such as files, cutting machines, and polishing machines to polish a cube iron block into a ball. The error can only be a single thread, which is the accuracy of a hair. This way you pass the test, which is considered level 8."

"The accuracy of a hair? This is quite difficult, and it can only be measured by human perception."

"It's okay if you are proficient enough, but no matter how high the accuracy is, it won't work. You must use advanced tools."

"sharp!"

"There are more people who are better than me, and there are also nine-level fitters and ten-level fitters."

Zhang Yuan sighed in his heart that everyone on Earth Age has a skill, and he may be the most mediocre one...

Of course, it was my former self.

This type of advanced fitter is cultivated to quickly restart civilization. The load capacity of the spacecraft is limited, and it is impossible to put every industrial machine tool on it. Some parts can only be made by hand.

Don't underestimate the power of human beings.

After swallowing the noodles in a few bites, Zhang Yuan stared at the group of metal creatures and studied them.

He is also a mechanical enthusiast and participated in the robot competition in college.

He is still good at programming. But because of his poor hands-on ability, he doesn't miss it very gorgeously.

Ye Kaifu's eyebrows were flying and his eyes were lit.

When talking about his baby, it seemed like he was so slutty that he was itchy: "This is my work in the ESL Robot Competition, this is a work in the national competition, and this... this...#...%;"

"You made it with a file?"

"Where can it be? Parts such as sensors are bought, and most of the parts are indeed handmade."

"Where is the robot program?"

"Well, most of them were also made by myself..." Ye Kaifu said this, his expression was a little unnatural.

because……

When he was in college, he accidentally became a licking dog.

When participating in the competition, he always brings his "girlfriend" and "girlfriend's male best friend", which is equivalent to having two legs.

But no matter how awesome a person is, there are still only a limited number of things he can do.

So, I have never won a first prize.

The licking dog ends up having nothing.

In a fit of anger, I simply left this sad world.

Zhang Yuan smiled and said, "No regrets, it's so difficult to win the first prize... I have participated, and I can't get anything!"

As they were chatting, Zhang Yuan picked up something like a robot and looked at it curiously.

It has a very good appearance and a texture full of metallic power. It is more than enough to use it as a movie mold.

After weighing it carefully, it was a good guy, almost twenty kilograms!

It takes a lot of time to design this robotic arm. And it is not difficult to make it really move.

This guy is a real academic master!

Ye Kaifu had a hint of pride on his face: "...This is the Power A, the second prize of the Galaxy Award that I spent four months to make, and was borrowed to film the movie "Terminator 100"!"

"Power Armor?"

"Actually, only one arm is done. If you do one action, it will do the same action as you do, will it play with it?"

"Try it!"

Zhang Yuan brought a very tight leather glove with great interest, covering his wrist.

There is a wire connected to the iron arm on the leather glove.

After turning on the switch, a mechanical rotation sounded, just like the motor started.

Ye Kaifu debugged it: "Okay, you can move."

Zhang Yuan tried to clench his five fingers into a fist.

Only a sound of mechanical movement was heard, and the iron arm was clenched into a fist with five fingers.

He loosened his five fingers and his iron arms too.

He asked curiously: "This leather glove is a pressure sensor, is it the famous mia pressure sensing system?"

"Yes!" Facing people who are also knowledgeable, Ye Kaifu became even more excited and talked about various parameters.

"Try to flatten it." He picked up a can and handed it to the front of the robot arm.

Zhang Yuan moved his arm carefully, but he saw that the iron arm also stretched and moved. After carefully holding the can, he exerted force with his five fingers.

Wow

The can was heart-wrenching roared and was pinched into an iron discus.

"The maximum grip strength can reach 320 kilograms, while the grip strength of ordinary people is only fifty or sixty kilograms."

Ye Kaifu said while wiping the sweat stains on his face: "How do you feel after experiencing it?"

"No need to talk about the advantages, just the disadvantages, otherwise I will not be able to make up my mind to eliminate it. I cannot bring it to heaven."

"Are you really talking about shortcomings?" Zhang Yuan scratched his head: "I don't know what to say..."

"Say it, say it, don't be polite!"

"Uh, it's a bit like an excavator to operate..."

"First, there is no feedback on the human body itself. If I don't look at it with my eyes, I don't know whether this iron hand has caught something or how much force it has been used. Compared with the human body, it is less touch and very inconvenient."

Ye Kaifu nodded, "Indeed, there is no human-computer interaction, you can only catch things with your eyes."

Zhang Yuan continued: "Second, I don't seem to be able to control the grip strength. I pinched the can in one go... Actually, I just want to pick it up gently."

“That’s right.”

"Third, this guy seems to have a little delay, and it doesn't move very smoothly. The distance the robot moves seems to be a little different from the distance I move... How can I say it, it's not very accurate."

Although Ye Kaifu was unhappy, he had to admit that what Zhang Yuan said made sense.

Moreover, he asked to find abuse himself, no wonder others were wrong.

He drooped his head: "Oh, you're right, so it only has a second prize. Let's abandon it."

"Goodbye baby, let's see you in the next life..."

He lifted the robot arm and put it into the box.

Zhang Yuan felt a little embarrassed. Are he too honest? He said this thing so worthless.

He hurriedly said, "Your model is pretty good. When it comes to movement, the gears have backlash, different frictions at different angles, and the design is very difficult. It is already very good to be able to make this."

"The model is good, what's the use? Actually, it doesn't have any technical content, it's just a time-consuming thing." Ye Kaifu shook his head, sighed, immersed in the sadness of losing his harem...

Seeing this, Zhang Yuan stopped talking and left this matter behind.

Anyway, I have nothing to do, so I should study. Studying can always bring you a sense of happiness.

“What should I learn…”

The knowledge I have learned is constantly flashing in my mind.

Suddenly, he had a flash of inspiration and remembered that there seemed to be a good idea in his father's tablet.
