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

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

"Do you want to give you half?"

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

With a meal, the two soon became familiar.

This guy's name is Ye Kaifu. He has the same education as him. He is only an undergraduate.

But the most important thing is that he is a "Grade 8 fitter", proficient in the manufacturing of various handicrafts.

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

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

Needless to say, it must be taller than him!

"Instead of filing a ball, we use basic tools, such as file, cutting machine and polishing machine, to polish a cube of iron into a ball. The error can only be a trace at most, that is, the accuracy of a hair. In this way, I'll pass. It's level eight. "

"The accuracy of a hair? This is very difficult. It can only be measured by the perception of human hands. "

"It's ok if you're proficient enough, but no matter how high the accuracy is, you have to use advanced tools."

"Awesome!"

"There are more people than me... There are also level 9 fitters and level 10 fitters."

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

Of course, it's who I used to be.

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

Don't underestimate the power of mankind itself.

Three or two people swallowed the noodles, and Zhang Yuan stared at the group of metal creations to study.

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

Programming level, he is still good. But because of their poor hands-on ability, they didn't rush into the street in a gorgeous way.

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

As soon as I talked about his baby, it was like complaining about his itch: "this is my work in the ESL robot competition, this is the work of the national competition, and this... This... #...%;"

"You filed it yourself?"

"How can I? Sensors and other parts are bought, and most parts are really made by hand. "

"What about the robot?"

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

Because

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

When participating in the competition, he always takes his "girlfriend" and "girlfriend's boyfriend", which is equivalent to one God with two legs.

But no matter how powerful a person is, what he can do is still limited.

Therefore, I have never won the first prize.

Licking the dog ends up with nothing.

In a rage, he simply left this sad world.

Zhang Yuan said with a smile, "I'm not sorry. How difficult it is to win the first prize... I've participated in it too. I didn't get a fart!"

Chatting, Zhang Yuan picked up something like a manipulator and looked at it curiously.

Its appearance is very good. It has a texture full of metal power. It's more than enough to be a film mold.

Weigh it carefully, good guy, almost 20 kilograms!

It takes a lot of time to design this manipulator. And if you want it to really move, the difficulty is not covered.

This guy is a real bully!

Ye Kaifu had a trace of pride on his face: "... This is the power a I spent four months to make, the second prize of the galaxy award, and I was borrowed to make the film terminator 100!"

"Power a?"

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

"Try!"

Zhang Yuan was interested in wearing a very tight leather glove, which covered his wrist.

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

After opening the switch, a sound of mechanical rotation sounded, as if the motor had started.

Ye Kaifu debugged: "yes, you can move."

Zhang Yuan tried to make five fingers into a fist.

There was only a sound of mechanical movement, and the iron arm was holding five fingers like a fist.

He loosened his five fingers and his iron arm.

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

"Yes!" Facing the same knowledgeable people, ye Kaifu was more energetic and talked about various parameters.

"Try squashing it." He picked up a can and handed it to the robot arm.

Zhang Yuan carefully moved his arm. He saw that the iron arm also moved with the expansion. After carefully holding the can, his five fingers worked hard.

WOW——

There was a roar from the tin can, which was pinched into a discus.

"The maximum grip strength can reach 320 kg, while the grip strength of ordinary people is only five or six kilograms."

Ye Kaifu wiped the sweat on his face and said, "what's the feeling of experience?"

"Don't mention the advantages, just the disadvantages, otherwise I can't make up my mind to eliminate it. I can't take it to heaven. "

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

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

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

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

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

Zhang Yuan continued, "second, I don't seem to be able to control my grip. I flattened the can at once... In fact, I just want to pick it up gently. "

"That's right."

"Third, this guy seems to have a little delay and doesn't move very smoothly. The moving distance of the manipulator seems a little different from that of me... How to say, it's not very accurate. "

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

Moreover, he asked for abuse himself. No wonder others.

He hung his head and said, "well, you're right, so it's only the second prize. Abandon it. "

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

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

Zhang Yuan feels a little embarrassed. Is he too honest? It's worthless to say this.

He hurriedly said, "your model is very good. When moving, the gear has back clearance and different friction at different angles. The design is very difficult. It's good to make it like this. "

"The model is good. What's the use? In fact, there is no technical content, it just takes time. " Ye Kaifu shook his head and sighed. He was immersed in the sadness of losing his harem

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

Anyway, I have nothing to do. I'd better study. Learning always brings happiness.

"What to learn..."

Once learned knowledge, kept flashing in my mind.

Suddenly, he had a flash of inspiration and thought of a good idea in his father's tablet computer.

Motion research of whole body motion mapping robot!
