A hot kiss.

"Brother Feng, can you go to my house? Gillian wants to lie in your arms..."

"Okay." Qin Feng nodded.

"Really? Great, Brother Feng, I thought you didn't want to. ”

"Your brother Feng is also a normal man..."Qin Feng decided that it was better to pick up the sun than to hit the sun.

Crunch... At this moment, the courtyard door on the side opened, and a middle-aged woman appeared inside, with short ear-length hair and a blue factory uniform.

The eyes of the two looked over, and Zhao Jiao was shocked at the moment: "Mom, are you back?" ”

"Well, your father's factory is getting bigger and bigger, and he can't keep busy, so I quit my job and work with him. Xiao Feng, did you send Xiao Jiao back? Come, come in and sit down. ”

Qin Feng looked up at the full moon above his head: "No, auntie, it's so late, I have to go back." ”

Zhao Jiao stomped her feet, and stopped talking, but could only watch Qin Feng's back disappear at the mouth of the alley.

Brother Feng, it's okay to stay in my house, Gillian secretly went to look for you in the middle of the night, why did you leave?

The next day, early in the morning.

Woohoo, woohoo!

In the duty room of the rubber shoe factory in Pingwang Town, Qin Feng opened his sleepy eyes, when he came back last night, Qin Feng fell asleep, and he slept until now, what time was it, why was there a dog barking outside?

Qin Feng put the quilt on his head and planned to continue sleeping, but the dog's barking was getting louder and louder, and he really couldn't sleep, so he could only sit up.

I have to go to Zhang Luo with Zhao Jiao to buy a house today, it's the Mid-Autumn Festival soon, spend the full moon, can you do it?

With such thoughts, he got up, washed his face in the basin, opened the door, and the barking of dogs outside again attracted his attention.

How to ignore?

Go out and check it out!

Pingwang Town rubber shoe factory near the house, in the corner of the house yard is a big black dog, because the courtyard wall is just a fence, so you can clearly see everything outside.

At this time, the big black dog bared its sharp teeth, and looked fiercely at the people who appeared outside the fence, barking wildly.

This person was not afraid at all, his eyes looked at the limbs of the big black dog through thick glasses, and his mind was constantly analyzing the structure, movement, and coordination of the four legs.

There is another person next to this person, who is being dissuaded at this time.

"Senior brother, you see this dog is so fierce, let's go, be careful that it breaks free from the chain and bites us."

"It's okay, senior sister, the happier it moves, the greater the amplitude of its limbs, and the more convenient it is for me to observe." Zhang Shengwang said, pushing his thick glasses.

Yesterday, I heard Qin Feng talk about the quadruped robot, Zhang Shengwang couldn't sleep all night, thinking about it over and over again, early this morning, the teacher checked the work of the double-density injection molding machine, and after no problem, he took the morning bus back, and did not alarm Qin Feng.

Zhang Shengwang and He Xiao sent the teacher to the car, and when they came back, they happened to see the dog in the fence, Zhang Shengwang couldn't walk, and decided to observe and study.

The big black dog is very angry, usually it barks like this a few times, passers-by will leave quickly, today there is actually a person who is not afraid! It screamed incessantly, and its neck was straining against the chain.

Crash! One of the chains was broken!

The big black dog dragged half of the chain, ran a few steps, rushed to the fence, kicked on his hind legs, jumped out with a whoosh, and fiercely rushed to the person who was observing him, opened his big mouth, and was ready to bite down on the leg of the person in front of him!

"Don't hurt my junior brother!" He Xiao didn't know where the courage came from, and she suddenly blocked in front of Zhang Shengwang, although she was also weak in her legs, but she still decided to protect her nerdy brother and lover.

Zhang Shengwang is not without manhood, it's not that he doesn't know how to protect He Xiao, but now his mind is full of the dog's four-legged movements, how various joints move, how the four legs cooperate, etc., he has been immersed in the thinking of research, when He Xiao blocked his eyes and cut off his sight from the dog, his brain entered the normal mode from the research mode.

After a moment of trance, he picked up He Xiao, held the girl's fluttering body in his arms, then opened his legs, turned around and planned to run.

Under normal circumstances, a two-legged person can't outrun a four-legged dog, not to mention that Zhang Shengwang is still holding a person, at this time, he will definitely not allow the big black dog to bite He Xiao, at most he will bite himself.

Before Zhang Shengwang turned around, he felt the heat of the dog's mouth on his calves, and even the teeth were about to pierce his pants.

He was shaken and knew he couldn't run.

"Senior sister, if I have rabies, don't come near me..."

Wait, it seems like it's okay?

Zhang Shengwang looked down, the dog's mouth was indeed very close to his leg, and he could bite it immediately, but it was a little bit worse! The big black dog still tried to stretch forward, but the half-cut iron chain he was dragging was dragged by someone!

When I looked behind the big black dog, I saw a familiar figure.

"Xiao Hei, if you dare to bite down, I will put you in the pot and stew! Chop off all four of your legs and send them to my brother for study! ”

When the big black dog that was barking wildly just now heard this, it suddenly wilted, stopped biting Zhang Shengwang, turned its head and waved its tail at Qin Feng.

This dog is not from the rubber shoe factory, but because of the close distance, when Qin Feng passes by, he will occasionally throw some food into it, even if it is half a tortilla, it is also a good thing for a dog who can only eat bran.

After going back and forth, the dog and Qin Feng became acquainted.

"Senior brother, let me down." He Xiao was shocked, and his tone was still trembling.

"Oh." Zhang Shengwang put He Xiao down, when his feet touched the ground, He Xiao was very sweet in his heart, and a little regretful, just hug himself for a while, this nerd usually doesn't take the initiative at all, are science and engineering men like this?

Zhang Shengwang's gaze looked at the dog's leg again.

"Senior brother, this dog's leg looks simple, it is seven moving joints, but the coordination of the four legs is quite complicated, just now, I have analyzed thirty-two ways to match..."Zhang Shengwang seems to have forgotten about the big black dog biting himself just now: "If you continue to study, there should be more, and this control procedure will probably be quite complicated." ”

"That's for sure, we need special algorithms. For quadruped robots, I have an algorithm idea here. ”

In September 2018, MIT Biomimetic Robotics Lab, a big bull in the field of quadruped robots, successively open-sourced Cheetah Mini, that is, the motor drive and all the running code of the mini cheetah robot, which immediately caused a sensation in the whole circle, which is a core secret!

Taking advantage of this shareholder wind, many domestic high-tech companies have begun to develop quadruped robots, mainly based on MIT's open source code to develop, but there are also some companies that are unmoved and insist on taking the road of self-development.

The self-developed one is a core secret, Qin Feng doesn't know, and Qin Feng can't memorize this open-source code, but he still understands the entire algorithm.
