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

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

Zhao Yi smiled.

The real advanced thing about the robot is definitely not the hardware, to put it bluntly, a full set of things that cost tens of thousands of dollars, and it is impossible to be advanced.

Everyone else looked at it curiously.

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

"Wait for a while, the robot will be officially launched, please help, don't get too close to me, otherwise it may affect the operation of the robot, and ah, everyone help keep quiet. ”

Zhao Yi was experimenting with high-tech in his own supermarket, and the fat boss also felt very face-saving, so 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 a show." ”

Quite a few people burst out laughing.

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

Zhao Yi asked them to help watch the machine and go into the supermarket to see the environment.

The fat boss is prepared.

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

After seeing the environment inside, Zhao Yi walked outside and waved his hand, signaling everyone to be quiet.

Xu Yue stood on the doorstep steps, leaving only the barrier-free passage, and the robot could directly turn to the barrier-free passage, calculate the slope and climb up the road.

The tests officially began.

Zhao Yi turned on the robot.

As soon as the robot system is loaded, a sentence is uttered, "Robot, Dongdong, ready to go!"

"Flutter!"

Zhao Hongjuan couldn't help laughing, quickly covered her mouth and looked left and right, and glared at Lin Xiaoqing fiercely.

She knew that her name was inseparable from Lin Xiaoqing.

Go on.

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

"Over. ”

"Ordered!"

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

Xu Chao stopped directly in front.

The robot stopped at 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 a short distance forward, and finally stopped in front of the barrier-free passage, and then climbed up the slope.

"Whew~~"

The people outside couldn't help but shout.

Even ordinary people who don't know know how difficult it is to find a way, a machine staggered the main entrance with steps, and found a barrier-free passage to climb up, which is definitely a great thing.

The robot walked to the main entrance of the supermarket, then paused and turned into the supermarket, and came to the outermost vegetable section.

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, and the vegetable area at the door, there are 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 robot arm to grab a cucumber and put it in the shopping basket behind it, then twisted around to grab a cucumber and put it back into the shopping basket.

"Hula~~"

"Bang Bang Bang~~"

"He did it!

The onlookers at the door of the supermarket were more excited than Zhao Yi, some people shouted excitedly, and some people simply applauded, the fat boss is a rare calm person.

He hurriedly shouted, "Quiet, quiet!"

The crowd quieted down.

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

The front of the shelf area is full of wine.

The robot walked quickly, almost without any stops, until it reached the second row of drink areas, and then began to stop continuously, and there was a distinct 'buzzing' sound in its stomach.

That's the sound of a fan.

When the amount of computation becomes large, the CPU usage increases, which also makes the fan heat dissipation faster.

There are many items in the beverage area, all of which have commonalities with 'carton milk', which makes it impossible to eliminate them at the first time, and the amount of calculation will increase immediately, and the robot stops in the milk area, but in the end it still does not make a choice, but continues to move forward.

"Hoo ......"

Many people feel that it is a failure.

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

"Nope. Zhao Yi didn't care, "Because I didn't set the data to match 100% with the boxed milk." ”

"Why?"

Zhao Yi just wanted to open his mouth but was stuck, he felt that it was too complicated to explain this problem to Lin Xiaoqing, so he simply said, "You can know it just by looking at it." ”

"Tell me!" Lin Xiaoqing was very dissatisfied.

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

"Okay!"

Zhao Yi simply said.

The robot judges that the object is identified by design, and the most basic is through color identification, and he uses the method of 'fuzzy calculation', which covers the largest range, even if it is the color.

For example, on a milk package, because of a cartoon character image, any color can appear, using the method of 'fuzzy calculation', a certain color coverage area, more than 50% is no longer calculated, but the color of the item is directly attributed to the color with the highest coverage.

The milk is set to be white.

However, there are also many 'square' box-like items in white packaging, and if the text cannot be recognized, other judgments need to be made, such as the range of box size, weight, and so on.

If 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 didn't have a 'certain' judgment at all.

He made dozens of potentially relevant judgments, and made percentages for each judgment, and finally determined the item through the percentage, and the item that exceeded the condition of 95% would be determined to be some kind of item.

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

In fact.

Of course, there is a better way to judge things, but what he needs to do is a 'human-like' approach, rather than simply calling data to make judgments.

At the same time, making judgments must also be unified in one way in order to achieve the common code, and it is impossible to change another way for simple or complex items, which is equivalent to writing a new set of code in order to identify a thing.

That would not be advisable.

Therefore, 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 many uncertain factors, will be more complicated to judge.

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

After turning all the places, he walked back to the door, suddenly stopped, turned towards the milk area, stopped and took a carton of milk, and then returned to the door.

"It's got!"

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

"That's amazing!"

The crowd at the door cheered again.

This time, everyone didn't care about the voice, because the robot completed the command and got the tissue, cucumber and milk, some people simply asked Zhao Yi, "Where did you buy it, so high-end?"

"Do you sell any of these robots? I want to buy one too?"

"How much is it?"

Zhao Yi first turned off the robot in the past, because the prompt was low on power, because there was no power to turn it off, which might damage the system or files, which was definitely not advisable.

Only when he came back did he smile, "The machine was bought, tens of thousands of yuan, and the program in it was designed by myself." ”

"That's amazing!"

"By the way, Zhao Yi is a mathematician, what mathematical problems have he solved, in fact, he is a computer master!"

"Hackers!"

"Hackers are amazing!"

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

......

Test successful!

Although there are still a lot of problems exposed in the middle, at least the core functions are played.

Pathfinding, no problem.

Item identification, no problem.

In fact, Zhao Yi only entered ten items in advance, and the others have not been entered yet, but the follow-up is a crossword puzzle, and with a basic compliment, just let Xu Chao put something 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 all went, and several neighbors nearby, including the supermarket owner Brother Wang, also got together at a table, Zhao Yi paid the bill very generously, and the neighbors sometimes help and take care of them, and invite guests to deepen the relationship.

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

It was taken by a mobile phone.

The pixels of the photos are very poor, but the number is very large, there are more than 40 in total, all of which have been uploaded to the Internet, and someone has exposed what happened and the whole process of the robot selecting items.

In addition, someone uploaded a short video, which is the part where the robot enters the supermarket.

Videos and photos are put together, it is very convincing, most people just watch the excitement, and sigh about the current intelligent high-tech, robots can be like people, normal shopping in the supermarket.

It's different for professional people.

Zhou Kai, the manager of Haitian Technology, is a professional person, and they have been working on an intelligent technology that can recognize items, and they didn't expect to see it on the Internet.

"Is this true?"

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

"This man is ......"

Zhou Kai was skeptical at first, he felt that high-tech intelligence would generally only appear in the laboratory, until he saw a photo with a face that seemed to have been seen.

"Yes...... That genius high school student?"
