Deep Space Fleet

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

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

"Do you want to share half with you?"

"Ah, thanks! I've been deciding which baby to take on the road and I forgot to eat."

With the fate of a meal, the two quickly became acquainted.

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

But the most important thing is that he is an "eighth-level fitter" who is proficient in various handicraft manufacturing.

Zhang Yuan became curious now: "Is that the kind of profession that can file an iron ball with a file?"

Eighth-level fitter, do you know how much salary they get?

Needless to say, it must be taller than him!

"Instead of filing a ball, use basic tools, such as files, cutting machines, and polishing machines, to polish a cube of iron into a ball. The error can only be a trace at most, which is the accuracy of a strand of hair. In this way Just pass the test, it's an eighth grade."

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

"It's okay if you are proficient enough, but it won't work if you have high precision. You must use advanced tools."

"sharp!"

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

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

Of course, it was my former self.

This type of senior fitter is trained to quickly restart civilization. The load capacity of the spaceship is limited, and it is impossible to carry every kind of 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 two or three bites, Zhang Yuan stared at the group of metal creations and began to study them.

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

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

Ye Kaifu's eyebrows were beaming, his eyes were shining brightly.

When talking about his baby, it seems to tickle his itch: "This is my work in the esl robot competition, this is the national competition work, and this...this...#...%;"

"You filed it out yourself with a file?"

"How can it be? The parts like sensors are bought, and most of the parts are really made by hand."

"What about the robot program?"

"Uh, I made most of them myself..." Ye Kaifu said this, with a slightly unnatural expression.

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 best friend", which is equivalent to one mind with two legs.

But no matter how powerful a person is, there are still limits to what he can do.

So, never won the first prize.

Lick the dog for nothing in the end.

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

Zhang Yuan said with a smile: "I don't regret it, the first prize is so difficult... I also participated, and I didn't even win it!"

While chatting, Zhang Yuan casually picked up a robot-like object and looked at it curiously.

It looks very good, with a texture full of metal strength, which is more than enough to be used as a movie mold.

Weigh it carefully, good guy, it's almost twenty kilograms!

Designing this robotic arm takes a lot of time. And if you want to make it really move, the difficulty is not unreasonable.

This guy is a real scholar!

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

"Power armor?"

"Actually, I only made one arm. If you make a movement, it will do the same movement as you. Do you want to play?"

"Try!"

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

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

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

Ye Kaifu adjusted it a bit: "Okay, you can move now."

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

There was only a sound of mechanical movement, and the iron arm also looked decent, with five fingers clenched into a fist.

He loosened his five fingers, and the iron arm also loosened.

He asked curiously: "Is this leather glove a pressure sensor, the famous MIA pressure sensor system?"

"Yes!" Facing the same knowledgeable person, Ye Kaifu became even more enthusiastic, and clattered about various parameters.

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

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

clatter——

There was a heart-piercing roar from the can, and it was crushed 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 from his face and said, "How does it feel after experiencing it?"

"Don't talk about the advantages, only the disadvantages, otherwise I can't make up my mind to eliminate it. I can't take it to the sky."

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

"Speak, speak, don't be shy!"

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

"First, there is no feedback to the human body itself. If I don't use my eyes, I don't know if the iron hand has caught something, and I don't know how much strength it uses. Compared with the human body, it lacks the sense of touch, which is very inconvenient .”

Ye Kaifu nodded, "Indeed, there is no human-computer interaction, so we can only use our eyes to estimate things."

Zhang Yuan continued: "Secondly, I don't seem to be able to control the grip strength. I crushed the can in one fell swoop... In fact, 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 moved by the manipulator seems to be a little different from the distance I move... How should I put it, it's not very accurate."

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

Moreover, it was he himself who asked to seek abuse, no wonder others.

He drooped his head: "Oh, you are right, so it only has the second prize. It's better to abandon it."

"Goodbye baby, see you in the next life..."

He picked up the robotic arm and put it in the box.

Zhang Yuan felt a little embarrassed, was he being too honest? It's worthless to say this stuff.

He hurriedly said: "Your model is quite good. When it is moving, the gears have backlash, and the friction is different at different angles. The design is very difficult. It is already very good to be able to make it like this."

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

Seeing this, Zhang Yuan didn't say much anymore, and put this matter behind him.

Anyway, nothing to do, let's study. Learning always brings happiness.

"What to 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 computer.

"Kinematics Research for Whole Body Motion Mapping Robots"!
