Genius of the Rules-Style System

A large group of people gathered at the entrance of the supermarket.

In the middle sits the experimental robot.

The fat boss walked around the robot a few times, stared at the robot's arms carefully, and reached out to touch it, "This is really advanced!"

Zhao Yi smiled.

The truly advanced thing about a robot is definitely not the hardware. To put it bluntly, a complete set that costs tens of thousands of dollars cannot be that advanced.

Everyone else looked at it curiously.

Zhao Yi introduced it, "We are going to test the robot automatic shopping system in Brother Wang's supermarket."

"When the robot is officially launched, please help. Don't get too close to the robot, otherwise it may affect the operation of the robot. Also, please help keep quiet."

His own supermarket would be used to experiment with high technology, and the fat boss also felt very proud. He quickly stood up and shouted at the top of his voice, "Quiet! Quiet! This is a high-tech experiment! I'm not letting you watch a show." "

Many people laughed out loud.

Zhao Hongjuan and Lin Xiaoqing are also among them.

Lin Xiaoqing and Zhao Yi stood very close to each other, as if they had become part of the robot team.

Zhao Hongjuan helped with the greeting, "Everyone, please help, calm down and look at this robot. Just look at it from a distance. Don't get too close."

Zhao Yi asked them to help look after the machine and went into the supermarket to check the environment.

The fat boss is prepared.

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

After looking at the environment inside and finding that there was nothing wrong, he walked outside to signal everyone to quiet down.

Xu Chao went over and stood on the steps at the door, leaving only the barrier-free passage. The robot could directly turn to the barrier-free passage, calculate the slope and climb up.

The test officially begins.

Zhao Yi turned on the robot.

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

"Puch!"

Zhao Hongjuan couldn't help laughing. She quickly covered her mouth and looked around, and gave Lin Xiaoqing a fierce look. She knew that her name was closely related to Lin Xiaoqing.

continue.

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

"complete."

"Instructions received!"

The robot stopped for about two seconds, turned on several cameras, and 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 check, walked forward for a short distance, and finally stopped right in front of the barrier-free passage, and then followed the slope Climbed up.

"Huh~~"

People outside couldn't help shouting.

Even ordinary people who don't know much about it know how difficult the path-finding process is. It is absolutely amazing for a machine to stagger the main entrance with steps and find a barrier-free passage to climb up.

The robot walked to the main entrance of the supermarket, stopped for a moment, turned and entered the supermarket, and came to the outermost vegetable area.

The fat boss's supermarket is not big, with only six rows of shelves in the middle and a whole row of shelves against the wall. The vegetable section at the door has two rows of vegetables and fruits, and there is an aisle in the middle.

The robot walked down the aisle, looking in a single direction, and soon stopped in front of the cucumber.

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

"Hula~~"

"Pa bang bang~~"

"It did it! It did it!"

The onlookers at the entrance of the supermarket were all more excited than Zhao Yi. Some people shouted excitedly, and some people simply clapped.

The fat boss was a rare calm person. He quickly pressed his hands and shouted, "Quiet, quiet!"

The crowd fell silent again.

The robot did not leave the vegetable area, but continued to walk along the aisle while constantly checking. After browsing the vegetable area, it went to the next aisle and entered the shelf area.

The front of the shelf area is full of wine.

The robot walked quickly, almost without stopping, until it reached the second row of the beverage area, and then it started to stop again and again, and its stomach also made a "buzzing" sound.

That's the sound of the fan.

When the amount of calculation becomes huge, the CPU usage becomes higher, which also causes the fan to rotate faster for heat dissipation.

There are many items in the beverage area, all of which have something in common with 'boxed milk', so it cannot be eliminated immediately, and the amount of calculation will immediately increase. The robot stopped in the milk area, but in the end it did not make a selection, but continued to move towards Go forward.

"call……"

Many people feel that it has failed.

Lin Xiaoqing also asked Zhao Yi, "Did it fail?"

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

"Why?"

Zhao Yigang wanted to speak but was stuck. He felt that explaining this problem to Lin Xiaoqing was too complicated, so he simply said, "You'll know just by looking at it."

"Tell me about it!" Lin Xiaoqing was very dissatisfied.

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

"All right!"

Zhao Yi simply said it.

The robot relies on design recognition to identify items. The most basic one is through color recognition. It uses the "fuzzy calculation" method to cover the largest range, regardless of the color.

For example, on a milk package, because of the cartoon character image, any color may appear. Using the 'fuzzy calculation' method, if a certain color covers more than 50% of the area, it will no longer be calculated, but the color of the item will be calculated. Go directly to the color with the highest coverage.

Milk is designated as white.

However, there are also many "square" box-like items in white packaging. If the text cannot be recognized, other judgments need to be made, such as the range of box size, weight, etc.

Even if all the conditions are met, it is still impossible to 100% determine whether it is milk, because there are still many similar things.

Zhao Yi didn't make a 'conclusive judgment' at all.

He classified dozens of possible relevant judgments and gave a percentage to each judgment. Finally, the item was determined by percentage. If the item exceeded 95% of the conditions, it would be determined to be a certain item.

This vague method is also the way the human brain makes judgments.

In fact.

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

At the same time, judgment must be made in a unified way to achieve common code. It is impossible to use another method for simple or complex items. It is equivalent to writing a new set of codes to identify one thing.

That is not advisable.

Therefore, when it comes to judging items, some items, such as cucumbers, are very simple and can be judged directly. However, for items such as milk and packaging, which have many uncertain factors, the judgment will be more complicated.

While Zhao Yi was explaining, the robot successfully selected the paper towel and then continued to move around the supermarket.

After turning around all the places, I walked to the door again, suddenly stopped, turned towards the milk area, and stopped directly to get a carton of milk.

"It's got it!"

"What's going on? Can't you get the milk?"

"awesome!"

The crowd at the door cheered again.

This time, everyone didn't care about the sound, because the robot completed the order and got paper towels, cucumbers and milk. Some people simply asked Zhao Yi, "Where did you buy it? It's so high-end?"

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

"how much!"

Zhao Yi first went over to shut down the robot because it was prompted that the battery was low. Forcing it to shut down due to lack of battery might damage the system or files.

He came back and said with a smile, "I bought the machine for tens of thousands of yuan, and I designed the program myself."

"This is awesome!"

"By the way, Zhao Yi is a mathematician and has solved some mathematical problems. In fact, he is a computer expert!"

"hacker!"

“Hackers are really awesome!”

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

…

Test success!

Although many problems were exposed midway, at least the core functions were fulfilled.

Pathfinding, no problem.

There is no problem with item recognition.

In fact, Zhao Yi only entered ten items in advance, and the others have not yet been entered, but the follow-up is a crossword puzzle. With the basic framework, Xu Chao can just put things in it.

There still needs to be a celebration banquet.

night.

Zhao Yi invited a big meal.

Xu Chao, Sun Liang, and Zhao Hongjuan's mother and daughter all went there. Several neighbors nearby, including supermarket owner Wang Ge, also joined us at the table. Zhao Yi paid the bill generously, and the neighbors sometimes helped and took care of them. , treating guests also deepens the relationship.

While a group of people were eating and drinking, photos of Zhao Yi testing the robot have been posted on the Internet.

That was taken with a cell 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 exposed what happened and the entire process of the robot selecting items.

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

Videos and photos put together are very convincing.

Most people just watch the fun and marvel at the current smart high technology. Robots can actually complete shopping in supermarkets like humans.

Professional people are different.

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

"is this real?"

"It doesn't look fake. How could an experimental robot appear in..."

"This person is..."

Zhou Kai was full of doubts at first. High-tech intelligence usually only appears in laboratories. In addition, there are too many black technologies in the robots and videos. It is not easy to find a path alone. , the identification of items seems to rely on dynamic graphics, and the technical content is too high.

Until I saw a photo.

There was a face on it that he seemed to have seen before, and he was immediately surprised, "Is it... the genius high school student who created the 'screening method'?"
