When it was almost time for dinner, one by one said that something was going on, and they were going home.

This is also no way out. The young men in the village either go out to do business, run transportation, or go to work.

刨 It is definitely not good to plan food on the ground these days. These women have to take care of the family.

To get to dinner, we need the dinner of the Zhang Luo family, the elderly want to eat, and the children should finish their homework after school.

There is nothing you can do about Zhang Yifan. Workers of this nature have this disadvantage and are more troublesome than casual workers.

一半 The man walked away halfway, this temporary production line basically could not be opened, so watching Zhang Yifan piled up with nearly a thousand finished products let everyone off work.

Before that, the old Zhang head picked up a load of melons in the field before returning. They are all ripe melons, and then they are not weighed. They are directly counted as ten dollars. Half delivery also sold seven or eight.

When everyone is done, the old man ’s head will simply clean up the ‘assembly line’, but there ’s nothing to clean up. Everyone has done a good job of sanitation before leaving;

I left some tools like a soldering iron. I didn't know where to put it for a while, so I dialed the electric table.

After finding all these things in a box, the old Zhang head got into Zhang Yifan's room;

"Xiao Fan, have you got anything in the field?" The old Zhang asked in a low voice.

I was thinking about the automatic pick-up machine for Wang Beibei. When I heard Dad's voice, Zhang Yifan was startled.

He thought he picked a bunch of melons to collect data, then verified the melon detector, and finally the matter of feeding pigs was revealed.

In fact, this matter is not big, and the melon in the ground is not worth the money. Take a dozen or twenty to experiment, and there is no waste in feeding the pigs in the future-without those inputs, where is the hottest melon now Artifact?

But the problem is that Zhang Yifan was guilty of conscience and was beaten and scolded by his father from an early age to a long time ago ....

"No, nothing ..." Zhang Yifan replied in support.

Old man opened his head to see his son's counseling. Based on his many years of experience, he still didn't know there was a ghost: "Say, Dad doesn't scold you this time ..."

"It's really nothing, haven't you seen that I've been busy at home during this time?" Zhang Yifan said stiffly.

"To be honest, I don't yell at you, I don't yell at you," said the old Zhang head. "If you didn't get anything wrong, our Gutian field will become so delicious this year?"

Didn't it come out? Zhang Yifan's heart finally let go.

"I have done nothing except tossed some of the organic fertilizer that I can't sell and piled up there into the melon fields and vegetable fields. I haven't poured water twice." Zhang Yifan said right now.

"Does that mean that our family will use this dung cake to grow melons next year, and it will be so delicious?" The old man said with a bit of expectation.

"I don't know, if you guessed right, it should, maybe, maybe the role of organic fertilizer," Zhang Yifan said ambiguous.

所以 "So, the food we eat recently is particularly tender and refreshing, should it be the same thing?" The old head was overjoyed ....

"Maybe?" Zhang Yifan was not sure.

"Catch Minger, I will order some vegetables and watermelons at home and sell them in the county. If we can get a good reputation, our vegetables will be more expensive than others' foods, then we have another way to live without pigs." The head said cheerfully.

The above request to close the small-scale pig farm made him sad, and then, in order to support his son's cause, he invested all his savings in the family, which can be said to be an internal problem and an external problem;

Now that he has a road to sustainable development, he is also very happy.

"But the pig farm is not allowed to do anything, no pig dung, I don't know if other dung can do it," Zhang Yifan quickly poured cold water.

"It's okay, as long as it can be done, let alone pig dung, I will find a way to get it even for panda dung," the old Zhang said arrogantly.

Zhang Yifan didn't have the courage to expose this big story, and the consequences of a quick mouth were either endangered or trained.

He just woke up: "Everyone will come to work at home tomorrow, and this work will take three or four days ..."

"Anyway, I can't help you at home anymore, and selling fruits and vegetables can come back at noon, when I will return from Xiaobei's car," said the old head.

Then threw down a sentence: "I'll go and see which farm truck will go to the county tomorrow, just to catch me." Then he hurried out.

Zhang Yifan didn't say anything. His father's character was very good, and it was useless to persuade him. I hope he can dispel the idea if he can't sell it.

However, there are not many vegetables growing in my own vegetable field. Even if it is easy to sell, it will not sell for a few days.

Continue to study how to pick up garbage automatically ...

Which way of travel is tracked or wheeled? The rubber track is too easy to damage, and the driving loss is too ...

If it is wheeled, off-road is a bit problematic. When walking on the sidewalk, there are obstacles everywhere. Taking non-motorized lanes, trash cans, etc., are still a little away from the road ...

Then, the internal combustion engine or electric?

These are the technical difficulties to consider ...

There is still a long way to go to solve the waste recycling problem of the Wang family. Zhang Yifan doesn't want to let Wang Beibei know that he's doing this. The idea of ​​avoiding risk, but in this case, many things will die.

I might as well get things out myself, even if it is not practical, you can modify it and put it in some other use.

Like the old Zhangtou, Zhang Yifan also has his own personality, and does not like to be interfered by others.

Battery cost and service life, internal combustion engine cost, service life;

对比 Comparison of electricity and fuel costs during operation, cost-effectiveness ...

Every conceivable factor was written down in Zhang Yifan's notebook and then calculated there using a calculator.

Zhang Yifan has always been particular about practicability. He definitely wants to use the simplest way and the lowest cost to achieve the function he wants.

GPS has some position deviations, and no one will set a positioning point for the trash can, so you need to add a picture acquisition and route correction system ...

I want to distinguish between plastic products and paper products, and then load them separately. How can the robot distinguish them clearly?

It is definitely impossible to use a method like a sweeper. In this case, any garbage is brought back.

辨识 Identification through the feedback of the grip of the robot arm is not an ideal method;

For example, in a carton, there is no way to compare the wet and dry hardness;

And, not to mention picking up trash to take pictures and analyze it seems a bit silly, that is, the sanitation workers saw the mess mess up, even everywhere, afraid that they would directly pick up the broom and hit the robot ....

There are a lot of problems in front of Zhang Yifan, but he finds it very interesting-this is a good challenge!
