Zhang Yuan opened the seafood noodles, intending to fill his stomach first.

Unexpectedly, the man opposite smelled the smell of food, and his Adam's apple involuntarily stirred.

"Do you want to give you half of it?"

"Ah, thank you! I was deciding which baby to take on the road and forgot to eat. ”

With a meal, the two quickly became acquainted.

This guy's name is Ye Kaifu, and his education is the same as his, but he is just an undergraduate.

But the most important thing is that he is an "eighth-level fitter" who is proficient in the manufacture of various handicrafts.

Zhang Yuan was curious: "That's the kind of ...... A profession that can file an iron ball with a file? ”

Level 8 fitter, I don't know how much salary there is?

Needless to say, it's definitely taller than him!

"Instead of filing a ball, we use basic tools, such as a file, a cutter, or a polisher, to polish a cube of iron into a ball. The error can only be a trace at most, that is, the accuracy of a single strand. In this way, you have passed, and it is considered level eight. ”

"The precision of a strand of hair? This is very difficult, and it can only be measured by human perception. ”

"It's okay if you're proficient, but not if you're accurate, you have to use advanced tools."

"Awesome!"

"Where, where, there are more people who are better than me...... There are also ninth-level fitters and tenth-level fitters. ”

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

Of course, it's the old self.

This type of high-level fitter is cultivated to be able to quickly restart civilization. The ship's payload is limited, and it is impossible to fit every industrial machine tool on it. Some parts can only be made by hand.

Don't underestimate the power of humanity itself.

Swallowing the noodles in three or two bites, Zhang Yuan stared at the group of metal creations and studied it.

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

Programming level, he is still good. But because the hands-on ability is too poor, it is not very gorgeous to hit the street.

Ye Kaifu's eyebrows danced, and his eyes lit up.

When he talked about his baby, it seemed to tickle him: "This is my work at the ESL Robotics Competition, this is the work of the National Competition, and this ...... This ...... #......%; ”

"You filed it all out of it yourself?"

"How can it? Sensors and other parts are bought, and most of the parts are indeed made by hand. ”

"What about bots?"

"Well, most of them are also made by myself......" Ye Kaifu said this, his expression was slightly unnatural.

Because......

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

When participating in competitions, he always brings his "girlfriend" and "girlfriend's male girlfriend", which is equivalent to one god with two legs.

But no matter how awesome a person is, there is still a limit to what he can do.

So, never won the first prize.

Licking the dog ends up with nothing.

In a fit of rage, simply leave this sad world.

Zhang Yuan said with a smile: "No regrets, how difficult is the first prize...... I've participated in it too, but I didn't even get any fart! ”

Chatting and chatting, Zhang Yuan casually picked up something like a mechanical hand and looked at it curiously.

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

Weigh it carefully, good fellow, almost twenty kilograms!

It takes a lot of time to design this robotic arm. And if you want to make it really move, it's not difficult.

This guy is a real scholar!

Ye Kaifu had a hint of pride on his face: "...... This is the power armor that I spent four months making, the second prize of the Galaxy Award, and I was also loaned to make the movie "Terminator 100"! ”

"Power Armor?"

"Actually, I only made one arm. You make a move and it will make the same action as you, play play? ”

"Try it!"

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

The leather gloves have a wire attached to the iron arm.

When the switch was turned on, there was a sound of a mechanical turning, as if the motor had started.

Ye Kaifu debugged: "It's okay, you can move." ”

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

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

He let go of his five fingers, and so did his iron arm.

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

"Yes!" In the face of people who also know how to do it, Ye Kaifu was even more energetic, and talked about various parameters cracklingly.

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

Zhang Yuan moved his arm carefully, only to see that the iron arm also moved with the telescopic movement, and after holding the can carefully, he exerted force with his five fingers.

Whoop -

There was a heart-rending roar from the can, and it was crumpled into a discus.

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

Ye Kaifu wiped the sweat stains on his face and said, "How does it feel to experience it?" ”

"I don't need to talk about the advantages, just the disadvantages, otherwise I wouldn't have made up my mind to eliminate it. There's no way I'm going to take it to the sky. ”

"Really, the shortcomings?" Zhang Yuan scratched his head: "I don't know what to say......"

"Say it, say it, you're welcome!"

"Well, it's a bit like an excavator......"

"First, there is no feedback to the human body itself. If I didn't look at it, I wouldn't know if the iron hand had caught something, or how much force it used. Compared with the human body, it lacks the sense of touch and is very inconvenient. ”

Ye Kaifu nodded, "Indeed, there is no human-computer interaction, and you can only rely on your eyes to grasp things." ”

Zhang Yuan continued: "Second, I don't seem to have a way to control my grip. The can was crumpled flat in one fell swoop...... Actually, I just want to pick it up gently. ”

"That's right."

"Thirdly, the guy seems to have a little bit of a lag and doesn't move very smoothly. The distance that the manipulator moves seems to be a little different from the distance I move...... How to put it, not very precisely. ”

Although Ye Kaifu was unhappy in his heart, he had to admit that what Zhang Yuan said was reasonable.

Moreover, it was he who asked for abuse, and no one else was to blame.

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

"Goodbye baby, we'll see you in the next life......"

He lifted the arm and placed it in the box.

Zhang Yuan felt a little embarrassed, was he too sincere? It's worthless to talk about this thing.

He hurriedly said, "Your model is quite good." When it moves, the gears have backlash, different friction at different angles, and the design is very difficult, so it is very good to be able to do this. ”

"The model is good, what's the use? Actually, there is no technical content, it is just time-consuming. Ye Kaifu shook his head and sighed, immersed in the grief of losing his harem......

Seeing this, Zhang Yuan didn't say anything more and left this matter behind.

Anyway, I have nothing to do, so let's study. Learning always leads to happiness.

"What ...... Learn?"

The knowledge I have learned keeps 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.

"Motion Research on Whole-Body Motion Mapping Robots"!
