After Li Fanyu returned to China, he first returned to the group, and He An Ning explained what had often happened in Russia during this period of time, as well as his own arrangements and plans for the future.

Although An Ning was still angry with him, he didn't say anything when he saw that Li Fanyu had not only been fine for a while, but also made the original messy Russian market plan clear.

It's just that seeing Li Fanyu himself outside for a while, he has lost a lot of weight, and he is a little distressed.

After getting An Ning's advice to go home for dinner on time at night, Li Fanyu agreed with his mouth, and then came to Zhengxin Power,

Liu Qing is working with Wang Yu and Xu Fufang on the products exhibited at the Zhengxin Industrial Exhibition, or trial products.

Seeing Li Fanyu coming, the three scholars immediately stepped forward and gave Li Fanyu a good meal, as Zhengxin's industry abroad became bigger and bigger, and the affairs of Zhengxin in China became more and more busy, the time for the four brothers to get together like this is getting less and less.

"Hey, okay, okay, you three are, I'm not. Let me see what you are going to use to the industrial exhibition this time. ”

Li Fanyu easily got rid of the three overly enthusiastic guys, and asked,

"Hey, hey, hey!" Liu Qing laughed wickedly, Zhengxin Power was responsible, and the group's spare distribution center was responsible for cooperating, and a design drawing of a concept product created under the joint effort was pushed in front of Li Fanyu.

That's a strange guy.

How so?

On the drawings, it looks like an excavator, with a tracked or stationary, or climbing chassis.

But zooming in, the bodywork of this monster is a huge robotic arm like a human hand, and on the decomposition drawing, this robotic arm has several different forms of work, including welding, weightlifting, and so on.

"This is?" Li Fanyu scratched his head, judging from the drawings, this thing looked like a mechanical arm was broken off the production line, magnified hundreds of times, and installed on a tracked chassis.

"That's right, now we have too many supporting projects at home and abroad, often a project has to be done for three or four months, or even longer. In fact, these supporting bars are not the most rare in terms of technology, mainly because we have to wait for the implementation of other aspects of the project while we have carried out our own projects.

For example, in the ship project, we have the engines installed, and we have to wait for them to finish welding and so on. It took a lot of time, so I thought, why not make a product that's big enough and sophisticated enough to do the time-consuming work of assembling and welding these big projects?"

When Li Fanyu heard this, he clasped his ears: "Isn't it just a large movable multi-functional mechanical working arm, look at the trouble you said!

Saying that, Li Fanyu learned Liu Qing's tone and said, "Hello, I want to have a soul-touching conversation with you tonight. Let's explore the true meaning of love in the midst of honesty...... You just said you want to sleep, what girl can't understand?"

"you!" Liu Qing said angrily: "This is different from a large mechanical working arm, what I want is the kind of thing that has a sensitivity of 70% of the human hand, and can be directly controlled by front-line workers without relying on programs." ”

Hearing this, Li Fanyu was shocked.

What the is this......

"Aren't you going to be a mecha, brother, dei!"

"Yes, yes, yes!" Hearing Li Fanyu's complaint, Liu Qing was happy: "I want to apply this thing to the industrial and civilian fields in the first step of mass production, and after the next step is to improve the flexibility and the structure of the power arm, I will move to the military! Think about it, after a few decades, all the armies will drive mecha derived from my products, fighting on land, in the sky, and in the ocean, what a majesty it is!"

The corners of Li Fanyu's eyes twitched: "There is an ideal brother, so now, how is your progress?"

"Hey, there's no problem mechanically, we have made a particularly complete set of bionic robotic arms with the clumsy center processor, but in terms of control...... Let's take a look."

As he spoke, Liu Qing tore off the tarpaulin behind him, revealing the huge prototype, that is, a robotic arm without a crawler chassis and erected on the pedestal.

He picked up a remote control that resembled a glove, with a large number of sensors and wires, and put it on his hand. Then, the switch of the robotic arm was turned on.

With a slight movement of his hand, a few seconds later, the top of the mechanical arm moved.

After just a few glances, Li Fanyu found a problem.

First of all, this huge robotic arm has a delay of about 7 seconds in operation. This is undoubtedly a very unfavorable situation for doing work.

For example, welding is extremely strict in terms of temperature and timing, so how can you wait for so long to react?

Moreover, with Li Fanyu's excellent visual observation, he found that the mechanical arm trembled slightly after each workmanship.

Li Fanyu touched his chin and said, "You use the mechanical arm to draw a horizontal line for me on the ground and I'll take a look." Draw slowly. ”

When the three scholars heard Li Fanyu's request, they looked at each other and smiled bitterly.

Liu Qing grimaced, and according to his request, drew a horizontal line on the ground.

I saw that the mechanical arm was trembling as if it had Parkinson's disease, and slowly drew a horizontal line on the ground.

When the mechanical arm was raised, Li Fanyu stepped forward to take a look and was immediately disappointed.

The situation was worse than he had imagined, and he saw a scratch on the ground of various shades and waves.

This means that the product designed by Liu Qing still has a long, long way to go.

At least in terms of precision, this thing is too substandard.

Li Fanyu thought for a while, and then ordered: "You pick up this box for me."

Liu Qing was completely defeated, "Forget Brother Fan, this kind of action of taking the box can't be done now, it's not stable enough, and the sensor can't handle the strength, either it falls down halfway through, or it directly crushes the box,"

Looking at the huge mechanical arm, Li Fanyu's mind was spinning rapidly.

After a while, he thought of the crux of the problem: this thing is just a bionic human hand, but as everyone knows, the human hand can react and make all kinds of delicate movements because there is a huge neural network within the bones and muscles.

And obviously, Liu Qing didn't make this thing,

Now whether it is the so-called sensing remote control or the internal sensing system of this robotic arm, it can't reach a single cent of neurons, how to talk about making the robotic arm reach 70% of the flexibility of human hands?

As he thought so, there was a rumble in his head.

"Tip: Detected that the current test user's R&D points have reached the upgrade standard!"
