The Black Tech Life of Scum

一 In the early morning of the next day, Zhang Yifan did not go to Li Bing, but went to Tiantian City with Wang Beibei;

北 Wang Beibei drank a little too much last night. The two of them blew up to 11 o'clock and stayed at Zhang Yifan's house.

之后 After Li Bing had misunderstood the incident, the old man who had nothing to do also drank wine with the two young men, by the way, pulling his glorious past from time to time;

I did n’t know how to pull it, but later Wang Beibei encouraged Zhang Yifan to chase Li Bing, and continued to give him suggestions;

And it looks a little tempting to look at Zhang Yifan ...

The old man looked down and threw a sentence: "One bachelor teaches another bachelor to pick up girls, one dares to speak, and one dare to listen ... If there is such a mind, let your mother mention it ... . "

Then, pack up and go back to the room to sleep ...

The next morning, Zhang Yifan was a little ashamed after waking up, so he went out to avoid it first, which was cold.

Go to Tian City, naturally, not to purchase components for making melon inspection artifacts, but to build garbage picking robots;

Along the way, Zhang Yifan kept asking Wang Beibei the price of the scrap purchase, and after listening, he was a little tangled:

Decadent paper floats at one ton at 1,500 to 2,000 yuan;

Decapitated plastic costs 25 to 3,000 yuan per ton;

Cans, 9,000 to 10,000 yuan a ton;

The scrap iron that is easiest to recycle, even after banning the import of garbage and scrap steel, is only about 18,000 tons;

The reason why scrap iron is easy to recycle is that it does not need to go through too much detection or discrimination;

Only an electromagnet mounted on a robot arm can be automatically collected and stacked by a program without occupying too much transportation space ...

Other recyclable waste products need to be analyzed before they can be collected, sorted and stacked, which is difficult to achieve ...

In other words, once the cost of this robot is too high, it may be impossible to get back a few tons of waste products. After all, it still needs to consume energy to maintain its operation;

The automatic garbage picking robot considered by Zhang Yifan is divided into two versions:

One is to automatically walk on the street, pick up recyclable garbage on the way and at designated garbage stations;

The other is dedicated to large landfills, similar to the role of a scavenger;

The former does not require too much off-road capability and terrain judgment, but needs to avoid pedestrians, vehicles and obstacles;

The latter requires strong off-road and self-rescue capabilities, because the garbage dumped in the dump is directly dumped by dump trucks, which is not strong;

The former is a bit easy to handle. Just install ordinary batteries and use motors. Just install a gravity sensor on the six limbs and feet, plus a gyroscope on the main body, and you can control the balance through the program ... .

之前 Before the detection system is not perfect, you can let the robot run only at night with fewer pedestrians and vehicles, such as after early morning;

Although a monster just like a leech runs across the street at night, it has a sense of sight when a monster sieges, but it can be equipped with lighting and red position lights;

People always take time to accept new things. When the car was just born, didn't it scare a lot of people?

The garbage dump version is a bit troublesome. If the motor is driven, the power and endurance are obviously insufficient. If lithium batteries are used, the cost will be too high ...

Zhang Yihang is not without a solution. The use of motorcycle engines can achieve the effect of small size and large output power. However, whether the fuel consumption can be recovered is a problem, or power distribution is a problem. After all, this is not a wheel drive ...

Another method is to use compressed air to drive each limb, which has the advantage that each cylinder can be accurately controlled by a solenoid valve;

The method of implementation is not difficult, adjust the stroke of each cylinder, use a motorcycle engine to drive the air pump (vehicle air compressor), of course, carry a large cylinder;

Zhang Yifan did not plan to eat a fat, so this time, he set aside the junkyard version-although this is obviously more rewarding;

After arriving in Tian City, Wang Beibei parked the car in a parking space, and then went straight into an Internet cafe, carrying a bottle of ice cola and a bag of potato chips bought in a small store ...

张 After several successful encounters with Zhang Yifan here, he is much better than before. If you do n’t understand anything, do n’t make any suggestions.

Talking is annoying and easy to face by reality ...

And Zhang Yifan directly started his buying;

Hardware stores, agricultural machinery parts stores, electronics city, computer city ... even sell glass fiber reinforced plastic ...

The reason why Zhang Yifan bought full transparent glass fiber reinforced plastic is mainly to directly observe the operating status inside the fuselage in order to make adjustments and optimizations by himself;

This type of reinforced plastic using glass fiber or its products as a reinforcing material is light and hard, non-conductive, stable, high mechanical strength, corrosion resistance and other properties. It can not be used as a car body for waste recycling cars ;

Moreover, it can also be heated and bent locally, or it can be sawed apart, then drilled with an electric drill, combined with self-tapping, fixed, or combined with glass glue, stitching ...

So it is a good material for non-standard fixtures in many factories. If it does not have the disadvantage of not being anti-static, it can even replace bakelite.

In Zhang Yifan's consideration, it is impossible to say that garbage is mixed with domestic garbage. There is no dirt at all. The main body made of iron or other materials will be corroded, and this fiberglass will be intact. Solve this problem;

Everything starts from low cost and can make money. It's so dirty that you can't see it. Then rinse it, and it's fine.

How many times do you have to change the car body if you use metal planks or the like?

After completing such a purchase ~ www.wuxiaspot.com ~ Zhang Yifan bought a new mobile phone, the previous mobile phone, I am afraid that I will stay in Li Bing's hands for a long time, pulling manure is also part of his career;

It didn't take long for me to owe Wang Beibei more than 10,000 yuan. It is expected that three automatic waste picking machines can be installed.

I did n’t buy a phone that was too expensive. In my early 2000s, the mobile phone, young people, just look at the appearance and the performance is OK. Huawei, it ’s too expensive, and it ’s too cheap.

As for the fruit, I haven't considered it, it is still in the poverty stage, and it is estimated that I will never think about it.

I have no idea of ​​national justice. I just feel that it is suitable for me, just enough.

If it wasn't for rice production outsourcing, and after-sales were all outsourcing, the students of the former vocational college were pitted a lot, and it was actually nothing to buy.

普通 For ordinary consumers, what they want is practical and reliable;

You can make a problem, but you have to solve it for me. Obviously, rice can't do this at present. When a problem occurs, the after-sales are all closed to find a way to ask for money.

With a new cell phone and a new number, Zhang Yifan called Wang Beibei as soon as possible;

He doesn't necessarily remember his parents' phone number, the only thing he remembers is Wang Beibei's cell phone;

Then, drive the car, load, and return home ...

After I returned home, Zhang Yifan started his retreat again, closing the door, and thunder couldn't move ...

The old Zhang family has long been accustomed to his routine, eating, and calling twice if he doesn't come out, even if it ...

Except for the old head who kicked the door twice during dinner time and saw no response, he just stopped ...

I ate, drank a little wine, and sighed there: son, is increasingly disobedient!
