Fang Yuan heard the cry of the little guy outside the door, thinking that something had happened to her, he hurriedly put down the things in his hand and ran out, only to see that the little man was already crying breathlessly, and hurriedly hugged her over, "Baby, what's wrong with you, you were fine just now, why did you cry suddenly?"

Fang's mother also turned off the vacuum cleaner and walked out at this time.

"Daddy...... You...... You don't want to ...... Don't sell me, I'm very well-behaved, I'm ...... Very obedient ....... The little guy wiped his tears and choked up.

Fang Yuan was confused when he heard this, when am I going to sell you, why don't I know?

But Fang's mother in the back didn't know this, she thought that Fang Yuan had told her something, she reached out and slapped Fang Yuan on the back of the head, and then hugged Xinxin into her arms, and comforted: "Baby, don't cry, grandma just sold your father, and she won't sell you." ”

Fang Yuan was confused, when did I say I was going to sell you? Why didn't I know that I was scummy enough to sell my daughter?

Fang's mother whispered comfort, the more she thought about it, the more angry she became, she stretched out her hand to give Fang Yuan the back of her head again, Fang Yuan hurriedly avoided the past, but the little man hugged grandma's arm at this time, "Grandma, don't hit my dad." ”

The villain himself was still aggrieved, and he was still thinking about his father, but Fang Yuan was very moved.

So he hugged the little man from Fang's mother's arms again and held him in his arms, "Baby, Dad told you that Dad will never sell you, because you are Dad's most precious and beloved baby." ”

"Really?" asked the little man with tears in his eyes, choked up.

"Really, Daddy assured you. Fang Yuan said seriously.

The little guy was sad when he heard this, and under the comfort of the two, this was the truth of the matter, Fang's mother and Fang Yuan looked at each other when they heard the words, but the two didn't laugh at her, this matter looked funny, but it just reflected the sensitivity of the villain's heart from the side.

Fang Yuan picked her up, walked into the house, pointed to the sweeping robot and vacuum cleaner on the ground and said, "This is small, this is big, grandma said that the sweeping robot is useless, so Dad said to sell the small one, not sell you." ”

The little guy was stunned for a moment when he heard this, and he began to be a little embarrassed, hugging his father's neck, shrinking his head on his father's shoulder, and looking up embarrassed.

"Baby, did Dad take you to buy Miao ornaments? It's so beautiful, come and show it to grandma." Fang's mother diverted her attention.

Sure enough, after listening to Fang's mother's words, the little guy raised his head, slipped down from his father, and showed off her collar to Fang's mother with his chest straight.

Fang's mother made a fuss with her for a while, and the little guy's mood gradually stabilized, so she began to wonder about the sweeping robot again, why did grandma say it was useless, why did Dad sell it?

After Fang Yuan showed her the operation, she immediately lost interest, "It's not as fun as my Xiaobai, it's not interesting at all." ”

The little white in her mouth is the all-terrain robot that Lu Shouyi bought for her, saying that it is a high-tech product, but it is actually a big toy, and she threw it aside after playing for a few days after buying it, or dogs, rabbits, and dolls are interesting.

As soon as she said this, Fang Yuan remembered the robot that Lu Shouyi had bought, that thing was quite expensive, it was about to catch up with the price of two sweeping robots, but it was completely incomparable to a sweeper, it had insect bionic six-legged, and integrated all the necessary sensors - it had a 720p camera with night vision, a three-axis accelerometer, a distance sensor, an infrared emitter, etc.

The head can be rotated at any angle of 360 degrees, making it easy to balance and walk on difficult terrain, and can run at speeds of 1.2 km/h and climb obstacles up to 375 px (13.23 cm).

And you can also use the open system interface, seamlessly link the third-party or self-compiled applet, Lu Shouyi said that he bought it for Xinxin, it is better to buy it for himself, he likes to play some cutting-edge technology products, anyway, he is not bad for money, if he encounters a good project, maybe he can also invest in it.

So Fang Yuan took Xiaobai out of Shin Shin's toy box, and then found a screwdriver to disassemble it and the sweeping robot, leaving only the motherboard inside.

Xiaobai's processor and built-in equipment are obviously much better than the sweeping robot, so Fang Yuan directly removed the original circuit board of the sweeper, and directly replaced it with Xiaobai's, and installed Xiaobai's original insect claws on the sweeper, and then a weird-looking, like a big spider sweeping robot was completed.

Mother Fang saw Fang Yuan tossing around, and some distressed things were dismantled for him, forming such an ugly thing.

"Mom, when I get it done, it will be easy for you to clean up the house in the future, and you can hand it over to it later. Fang Yuan patted his chest and assured, although it had been reassembled, it was not complete at this point.

Robot production technology is very easy, imitation insects, imitation beasts, and the most difficult human-like robots, there is no difficulty in the production process, to say that there are only two difficulties, the first point is energy endurance, the second point is the degree of intelligence.

The wisdom of the robot is limited by the intelligent program, and programming is exactly what Fang Yuan is best at, this month he is not only to build the environment of the DH language, but also has a more intuitive understanding of the application of this language, not to mention that there is a book in his mind "Principles and Maintenance of Agricultural Machinery", this book not only introduces the mechanical structure in detail, but also involves power drive and mechanical intelligence.

So Fang Yuan connected the original Xiaobai's control center to the computer, and then optimized all the original systems and instructions inside, and recompiled the running logic for it with a new algorithm.

Because there was already a ready-made program in his mind as a reference, Fang Yuan only needed to compile it with the computer, and then rewrite it into Xiaobai's control core, so as long as the hand speed was fast enough, it was not troublesome to get it, during this period, the villain came to see Fang Yuan a few times, and when he saw his father's serious work, he didn't bother him, and went to play with his grandparents.

When the sun set and a ray of afterglow shone in through the window, Fang Yuan pressed the last enter key, then got up and stretched, unplugging the computer cable.

"Dad, are you done?" Xinxin, who was shooting the ball with her grandfather in the living room, saw Fang Yuan come out, and immediately ran over and hugged his legs.

"yes, it's done. Fang Yuan raised the strange-looking sweeper in his hand.

"Oh, it's ugly. Shin Shin glanced at her, not at all interested.

Fang's father was also very dissatisfied, "After a busy afternoon, he didn't play with the children, and he didn't cook dinner, so he tossed such a strange thing?"

Fang Yuan ignored her, but said to Xinxin, "You call Xiaobai hello." ”

Xinxin glanced at him, but still shouted obediently: "Hello Xiaobai." ”

The robot in Fang Yuan's hand immediately reacted, and responded, "Hello little master, what do you command?"

"Wow, it can talk?" the little guy was particularly surprised.

Fang Yuan bent down and put it on the ground, the robot immediately took a few steps underground, the camera above his head rotated 360 degrees, and then went straight to Xinxin's feet, so frightened that the little guy hurriedly took a few steps back, mainly because its strange appearance was really a little scary.

"You can have it clean up the house now. Fang Yuan squatted down, let Xinxin lean on him, and whispered in her ear.

With his father behind him, the little guy was not afraid, so he said to Xiaobai: "You go and clean up." ”

When the robot heard this, the six grabs immediately walked around the house, the camera above its head rotated 360 degrees, and then modeled the scanned scene in the house, and then began to sweep the ground, and when it encountered something slightly larger, it would avoid it, or prop up the grab and step over, Xinxin just thought it was fun, but Fang's father was watching from the side with a big mouth.

In fact, Fang Yuan's time in the afternoon, if he really wrote an intelligent program, it would be complete nonsense, he just changed the algorithm and logical judgment again, and added Xunfei's voice control system outside the interface, which made it look like it was wise.
