Rule system

A large group of people gathered around the entrance of the supermarket, looking at the experimental robot in the middle.

The fat boss was also among them, and went around a few times, staring at the robot's arm carefully, "This is really advanced!"

Zhao Yi smiled.

The real advanced level of the robot is definitely not the hardware. To put it bluntly, a complete set of things worth tens of thousands of dollars cannot be advanced.

The others looked curiously.

Zhao Yi also introduced, "We are going to test the robot automatic shopping system at Brother Wang's supermarket. The three things we selected are cucumbers, milk and paper towels."

"Wait for a while, the robot will officially start. Please help. Don't get too close to me, otherwise it may affect the robot's operation. Also, please help keep quiet."

Zhao Yi experimented with high-tech in his supermarket. The fat boss also felt very face. He quickly stood up and said in a loud voice, "It's all quiet! Quiet! This is experimental high-tech! It's not for you to watch the show."

Many people laughed out loud.

Zhao Hongjuan and Lin Xiaoqing were among them. Lin Xiaoqing and Zhao Yi stood very close, and Zhao Hongjuan also helped greet, "Everyone, help, quiet down, look at Xiaoyi's robot, don't get too close."

Zhao Yi asked them to help look at the machine and go into the supermarket to check the environment.

The fat boss is prepared.

The distance between the shelves in the supermarket has been expanded a bit, and the inside has become much cleaner. There are no obstacles such as boxes between the shelves and the shelves, which will make the robot run more smoothly.

After seeing the environment inside, Zhao Yi walked outside and waved to signal everyone to calm down.

Xu Chaogu stood on the doorstep, leaving only the barrier-free passage, and the robot could directly turn to the barrier-free passage, calculate the slope and climb up along it.

The test officially begins.

Zhao Yi opened the robot.

After the robot system is loaded, immediately say one sentence, "Robot, Dongdong, is on standby!"

"Pump!"

Zhao Hongjuan couldn't help but smile, and quickly covered her mouth and looked around, giving Lin Xiaoqing a fierce look.

She knew that the name was inseparable from Lin Xiaoqing.

carry on.

Zhao Yi said, "Start the shopping mode, go to the supermarket right in front, buy two cucumbers, a pack of tissues, and a box of milk."

"complete."

"Received instructions!"

The robot stopped for about two seconds, several cameras were turned on, and they walked straight ahead.

Xu Chao stopped right in front.

The robot stopped about 0.5 meters away from Xu Chao, then moved laterally to the corner of the barrier-free passage, then turned left and right to view, walked a short distance forward, and finally stopped in front of the barrier-free passage, and then followed the slope. Climbed up.

"Huh~~"

The people outside couldn't help shouting.

Even ordinary people who don't understand know how difficult it is to find the way. A machine staggers the stepped main entrance and finds a barrier-free passage to climb up. It is definitely a great thing.

The robot walked to the main entrance of the supermarket, then stopped and turned to enter the supermarket, and came to the outermost vegetable area.

The fat boss’s supermarket is not big. There are only six rows of shelves in the middle, and a whole row of shelves against the wall. The vegetable area at the door contains two rows of vegetables and fruits with an aisle in the middle.

The robot walked along the aisle, looking in a single direction, and quickly stopped in front of Cucumber.

After a gap of about two seconds, the robot stretched out its robotic arm to grab a cucumber and placed it in the shopping basket it was carrying behind, then twisted it around to grab a cucumber and put it back in the shopping basket.

"Hula~~"

"Papa Papa~~"

"He did it! He did it!"

The crowds at the entrance of the supermarket were more excited than Zhao Yi. Some people shouted out excitedly, and some simply clapped their hands. The fat boss was a rare calm person.

He hurriedly pressed his hand and shouted, "Quiet, quiet!"

The crowd calmed down.

The robot did not leave the vegetable area, but continued to walk along the aisle, while constantly checking, and after strolling around the vegetable area, it reached the next aisle and entered the shelf area.

There is wine in front of the shelf area.

The robot walked quickly, almost without any stop, until it reached the second row of beverage area, it began to stop continuously, and there was an obvious'buzzing' noise in its stomach.

That is the sound of the fan.

When the amount of calculation becomes huge, the CPU usage becomes higher, which also speeds up the cooling speed of the fan.

There are many items in the beverage area, all of which are in common with the'boxed milk', which makes it impossible to exclude them immediately. The calculation amount will increase immediately. The robot stops in the milk area, but in the end it still does not make a choice, but continues to Go ahead.

"call……"

Many people think it is a failure.

Lin Xiaoqing also asked Xiang Zhao Yi, "Is it a failure?"

"No." Zhao Yi didn't care, "because I didn't set the data to match 100% of the boxed milk."

"why?"

Zhao Yi just wanted to speak but got stuck. He felt that it was too complicated to explain this to Lin Xiaoqing, so he simply said, "You can see it by looking at it."

"Talk about it!" Lin Xiaoqing was very dissatisfied.

Sun Liang also said, "Zhao Yi, explain, I don't quite understand!"

"Ok!"

Zhao Yi said it simply.

The robot judges objects by design and recognition. The most basic thing is to recognize by color. He uses the method of "fuzzy calculation" to cover the largest range, even if it is the color.

For example, on a milk package, because of the image of a cartoon character, any color may appear. Using the method of "fuzzy calculation", the area covered by a certain color will not be calculated if it exceeds 50%, but the color of the item Attributed directly to the color with the highest coverage.

Milk is determined to be white.

However, there are many white-packaged'square' box-shaped items. If the text cannot be recognized, other judgments are needed, such as the size and weight of the box.

When all the conditions are met, it is still impossible to judge 100% that it is milk, because there are still many similar things.

Zhao Yi did not make a'sure' judgment at all.

He made dozens of possible related judgments, and made a percentage for each judgment, and finally determined the item by the percentage. If the item exceeds 95%, it will be determined to be a certain item.

This vague method is also the way the human brain judges.

In fact.

If you just judge items, of course, there are better ways, but what he has to do is a "human-like" approach, rather than simply calling data to make judgments.

At the same time, the judgment must be made in a unified way to achieve the common code. It is impossible for simple or complex items to change to another way, which is equivalent to rewriting a set of codes to identify something.

That is not desirable.

So in terms of judging items, some things, such as cucumbers, are very simple and can be judged directly, while items such as milk, with packaging, and items with many uncertain factors, the judgment will be more complicated.

In the process of Zhao Yi's explanation, after the robot successfully selected the tissue, it continued to move around in the supermarket.

After turning all the positions, he walked to the door again, suddenly stopped, turned towards the milk area, stopped directly to take a carton of milk, and then returned to the door.

"It got it!"

"What's the matter? Can't you get milk?"

"awesome!"

The people at the door cheered again.

This time everyone didn't care about the sound anymore, because the robot completed the order and got the tissues, cucumbers and milk. Some people simply asked Zhao Yi, "Where did you buy it, so advanced?"

"Is this kind of robot available? I want to buy one too?"

"how much!"

Zhao Yi used to shut down the robot first, because it indicated that the battery was insufficient, and the system or files might be damaged, which is definitely not advisable.

Only when I came back, I smiled, "I bought the machine, tens of thousands of dollars, and the program inside was designed by myself."

"This is awesome!"

"By the way, it's all because Zhao Yi is a mathematician who has solved some mathematical problems. In fact, he is a computer expert!"

"hacker!"

"Hackers are amazing!"

Zhao Yi forced a smile on his face and complained dozens of times, "Does this have anything to do with hackers?"

...

testing successfully!

Although many problems were exposed midway, at least the core function was played.

Pathfinding, no problem.

There is no problem with item identification.

In fact, Zhao Yi only entered ten items in advance, and none of the others were entered yet, but the follow-up was a crossword puzzle. With basic compliments, just let Xu Chao put things in it.

There is still a celebration banquet.

at night.

Zhao Yi invited a big meal.

Xu Chao, Sun Liang, and Zhao Hongjuan’s mother and daughter were there. Several nearby neighbors, including the supermarket owner Wang Ge, also joined the table. Zhao Yi paid the bill generously, and the neighbors sometimes helped and looked after Inviting guests to deepen the relationship.

When a group of people were eating and drinking, the photo of Zhao Yi testing the robot had been posted on the Internet.

It was taken on a mobile phone.

The pixels of the photos are very poor, but the number is very large. There are more than forty photos in total. All of them have been uploaded to the Internet. Someone has exposed what happened and the whole process of robots selecting objects.

In addition, someone uploaded a short video of the robot entering the supermarket.

Putting the video and photos together is very convincing. Most people just watch the excitement and sigh with the current smart high-tech. Robots can actually complete shopping in the supermarket like humans.

Professionals are different.

Haitian Technology Manager Zhou Kai is a professional person. They have been studying an intelligent technology that can identify objects, but they never expected to see it on the Internet.

"is this real?"

"It doesn't look like a fake, how could an experimental robot appear in..."

"This person is..."

Zhou Kai initially questioned. He felt that high-tech intelligence would generally only appear in the laboratory until he saw a photo with a face that he seemed to have seen.

"Yes...that talented high school student?"
