Chapter 810

Yu Le smiles meaningfully, then pushes Yu Yin forward. Xu Haotian follows him, crosses the shooting range and enters a robot area where robots are displayed one by one.

"Are these failures?"

With the stump area, Xu Haotian guesses that these robots are all failed products, so they are displayed here.

"Bang."

Xu Haotian's back was hit by a blow, Xu Haotian the whole person staggered two steps, turned around, saw a robot hit Xu Haotian's head, Xu Haotian quickly rolled over to one side.

"Yu Le, you are naughty again."

The sound of the aftersound rang, Xu Haotian quickly jumped out, the robot kicked a space, Xu Haotian finally understood that these robots can move, they are not a failure, they are displayed here, also do not know why.

Xu Haotian stood up, looked at the robot did not move, reached out to push the nearest robot, the robot did not move, Xu Haotian breathed a sigh of relief, "aftersound, these robots are used to fight?"

Looking around, Xu Haotian quickly walked through several robots, where to clear the shadow of Yu Le? Looking at hundreds of robots at a glance, where can I still see Yu Le.

"Stop it, have fun."

Xu Haotian quickly ran out and searched one by one, but he searched all over the robot area, but he didn't see Yu Le.

"Damn it, I really lost it."

This can be a shame, even lost, Xu Haotian simply pulled a robot to the ground, began to study the robot, anyway, Yu Le will definitely come to pick up his own.

I have studied robots for a long time. These robots are humanoid robots, but they are still relatively heavy. Obviously, the level is not high, and the motor function is not very developed. Otherwise, Xu Haotian would have been beaten up just now.

"Dong Dong..."

Xu Haotian knocks on the chest of the robot, making a dull sound, not like the sound of metal, but with the texture and feel of metal.

"Come on, don't tear it down."

The voice of the aftersound rang, Xu Haotian looked back, saw the aftersound behind him, Xu Haotian quickly got up, "where did you come from, there is no door."

Yu Yin reaches out his hand. Xu Haotian grabs Yu Yin's hand. Yu Yin's wheelchair moves forward slowly. Xu Haotian walks along and finds that he seems to have crossed something. Looking back, everything outside has changed. Where is there any robot.

"What's this?"

Xu Haotian can't believe looking at all this. He seems to have crossed from one space to another.

"It's called the radio wave isolation wall. It's not a space crossing. Radio waves affect the human brain, so what you see is a wall. In fact, there is nothing."

Yu Yin released Xu Haotian's hand, "let's go, grandpa has been waiting for you for a long time."

"Who said that he would not lose it?"

Yu Le comes up to Xu Haotian and teases Xu Haotian. Xu Haotian is extremely thick skinned, pretends not to hear him, and pushes his voice forward slowly.

Through the long corridor, came to a huge space, in this space, saw a lot of science and technology personnel, are working there.

What makes Xu Haotian feel incredible is that several staff members, holding a metal bone, are using fine sandpaper to grind the metal bone under a thin water pipe. In such a technological space, can they still use sandpaper to grind the metal bone by hand?

Xu Haotian curiously came up. The staff didn't even lift their heads. They were carefully polishing there. The sandpaper was gently sanding, as if they were doing a very delicate work.

Xu Haotian looked at the Afterword, "isn't it better to polish by machine? How can you still use manual work?"

"The accuracy of the machine is good, but the delicate work still needs manual repair. If the matching of the joints is a little poor, it will affect the activity and the cause of science and technology. It is not as simple or as bright as you think. Many programs need manual work."

Yu Yin explains that in the eyes of laymen, such high-tech things should be polished manually, which is not high-end at all. However, technology is just like this. Some things can't be made by machines. Behind the bright products, there are often unknown hardships.

Sandpaper grinding almost, after working water first, picked up an instrument to shine on the joints, pasted on the top of careful inspection for several times, and then picked up sandpaper again for grinding.

Xu Haotian shakes his head. His imagination limits his understanding of science and technology. Xu Haotian squats down and wants to see how far the workers want to go.

After polishing for a long time, the worker picked up the instrument again and checked the joint again. This time, it seems to be qualified. The worker picked up another accessory, covered it on the joint, and then tried to run it in.

Two parts have been tried for more than ten times, and the workers are satisfied with putting them on the conveyor belt of the assembly line. The conveyor belt of the assembly line passes the parts away, and then another worker picks up the parts, matches them, and grinds them again.

This process is very boring and boring. Xu Haotian watched it for about ten minutes and stood up. Xu Haotian never imagined that such a high-tech thing was made in this way“ What about? It's a surprise, isn't it? " Yu Tian's voice rang, Xu Haotian looked back, looked at Yu Tian, and quickly said hello, "old Yu." Yu Tian nodded with a smile and pointed to the huge production space. He was in a very complicated mood and said, "300 sets of accessories can be produced here every day. After matching procedures, in the end, only one set of qualified products can be produced in three days."“ This will consume a lot of precious metals, human, material and financial resources. In the end, the cost of this set will reach about six million, and what comes out of the six million is not finished products, only qualified semi-finished products. " Yu said with a sigh, his face showed a sense of helplessness, "China's industry started late, developed late, for high precision parts, we still can't machine production, so a lot of products, we developed, have good performance, but can't distribute to the army."“ You should see the stumps when you come here. Those are the assembled products. From the test, to the first generation, to the second generation, hundreds of sets have been accumulated, but those are still failed products. Only about one tenth of the products are really successful. " Yu Tian's words made Xu Haotian frown. Yu Tian asked Yu Yin to take him to see these things, just to tell him that it's too difficult to produce these things, or that the cost is too high? It should not be. The rest of the day, he wants to complain to himself, and he wants to blackmail him. He wants to complain to himself in advance, and he just wants to stop the lion talking. Xu Haotian wants to understand this, and he curses in his heart, old fox.
