Huang Yueying saw Sun Yu staring at the wooden cow and flowing horse like a demon, and she was reluctant to take her eyes off, who knew that he was nostalgic for the robot engineering he learned in his later life, and thought that he was fascinated by his own design.

So she walked to the side of the wooden ox and the horse, gently picked up the two handrails that stretched out from the back of the wooden ox and the horse, and pushed it forward.

Huang Yueying deliberately pushed it to an uneven depression in the yard, and then put the wheels below into the belly of the car, turning it into walking on four feet, she pushed the wooden cow into the depression, only to see the four feet of the wooden cow slowly moved, just like a real cow walking, the uneven ground had no effect on it, as if walking on the flat ground.

Sun Yu was overjoyed: although this thing is wooden, the technical content of it is not very high, it is the ancient prototype of a quadruped robot, but after all, it is the originator of quadruped robots, and to see this kind of thing with his own eyes is as exciting as a later generation of gun enthusiasts when they see an arquebus.

This thing is an antique among antiques, and it is the beginning of human robot research, Sun Yu, a broken scientist, was so excited that his whole body trembled, he walked to the side of the wooden ox and flowing horse, reached out and stroked its wooden back, and said excitedly: "Miss Huang, can I take this thing apart and take a closer look?" ”

Huang Yueying glanced at Xiao Xu Shu next to her, and then said to Sun Yu: "Okay, you can play casually, I'll take this little sister of your family to the kitchen to find something to eat." ”

Sun Yu was fascinated by the robot, and he didn't notice Huang Yueying's small movements, he happily pushed the wooden ox and the horse to play.

Huang Yueying beckoned to Xiao Xu Shu and said, "Little sister, come to the kitchen with my sister." ”

Xiao Xu Shu grinned and ran into the kitchen with Huang Yueying.

As soon as she entered the kitchen, Huang Yueying lowered her voice and said, "Xiaoshu, did that man bully you?" ”

Xu Shu shook his head and said, "You didn't bully me!" It was me who bullied him, hehe, I didn't talk to him, and I called him uncle when he occasionally said a word, so angry that he blew his beard and glared. ”

Huang Yueying touched her head distressedly, and asked again, "Did you eat well and sleep soundly with this man?" ”

Xiao Xu Shu nodded and said, "It's all good, I just want to think a little bit about Sister Zhuge , Xiaotong, Xiaohui...... Sister Huang, are you going to take me back to Wollongong? Let's kill that bad uncle out there. ”

Huang Yueying smiled bitterly and shook her head and said: "He doesn't look very bad, Sister Zhuge wants me to tell you, you follow him first to see if he is a good person or a bad guy, if it is a bad guy, Sister Zhuge will come to kill him and save you back." ”

Xiao Xu Shu pouted and said, "Sister Zhuge said so?" Alright then, I'll play with him for a while. ”

At this time, Sun Yu walked a few steps in the yard pushing the wooden ox and flowing horse, and the initial excitement of touching the antique robot with his own hands had slowly cooled down. After all, this is a very rudimentary robot, and in the eyes of roboticists like Sun Yu in later generations, its function is simply weak.

After pushing a few more steps, Sun Yu found that it has two major shortcomings, the first is the flexibility of the machine, because the bearings of this era have not yet established a scientific theoretical system, all rely on the experience of craftsmen to produce, so the whole machine is a little out of place, difficult to sleek.

The second is the problem of power, this thing is propelled by manpower, although it can go up and down the hill, but the manpower is limited, when the wooden ox stream is immediately filled with food, this thing is not a wheel, but four feet. The person who pushes the ox and the horse needs a lot of force to move it forward.

To put it simply, this thing looks like a sleek thing, but it's actually weak! Compared with Sun Yu's later life, he used his imagination to redesign the wooden ox flowing horse.

But this is also a very normal thing, if the wooden ox and flowing horse designed by the robot engineer thousands of years later are not as good as the ancients thousands of years ago, Sun Yu might as well go and die.

When Huang Yueying came out of the kitchen with Xiao Xu Shu, Sun Yu couldn't help but shout at Huang Yueying: "Miss Huang, I tried to play with the wooden cow flowing horse you made, this thing is really powerful, but I also made a wooden cow flowing horse when I was idle, I don't know if Miss Huang is interested in seeing it?" ”

When Huang Yueying heard this, she was shocked: This man has also been a wooden cow and a flowing horse? No one has ever made the design of my wooden cow and flowing horse, even Zhuge Liang's ghost and elf are full of praise when he sees it, this man actually has his own design?

She couldn't help but be curious: "Where is your wooden ox and flowing horse?" Take it out and I'll take a look. ”

Sun Yu had the heart to stay at the Huang family, and wanted to touch Huang Yueying's bottom to see if she was a "god of work", so he smiled and said: "I came from afar, how can I take it with me, or you can lend me the carpentry tools, and I will spend a few days to build them for you to see." ”

"How many days?" Huang Yueying hesitated for a moment, thinking: There are still a bunch of little girls living in my house, how can I let you live here, so she said: "It's too inconvenient for me and my mother to live here in my house, and you and your companion and two men!" ”

Sun Yu smiled and said, "We can rent a house nearby, and come to your house during the day to disturb us." ”

Huang Yueying was also very interested in the wooden ox and flowing horse he designed, so she agreed, and lent Sun Yu his hammers, chisels, axes, saws and other tools.

Sun Yu thought to himself: If Huang Yueying is the "God of Workers", and I don't know what kind of martial arts the "God of Works" is, in order to force her to use it and let me confirm it with my own eyes, I have to make my own wooden ox and flowing horse magical, and completely defeat her, so that she may use the "God of Works" martial arts skills to try to surpass my design.

Okay, just do it! Let's start with the more complicated ones.

Sun Yu asked Yan Yun to go to the neighborhood to buy some dry wood and come back, while he lay on the ground first and drew the drawings. If you want to surpass the wooden cow and flowing horse designed by Huang Yueying, it is impossible to play tricks on the appearance alone, the key is still inside, especially the power part.

Sun Yu decided to first use a hand-cranked power system, that is, to make a joystick that is shaken by human hands, use this rocker to connect a gear set, and drive the four legs of the wooden ox and flowing horse to move through the gear set.

So Sun Yu first drew a gear set on the ground with a tree branch, the largest gear was fixed at the end of the joystick, and then used this big gear to drive a slightly smaller gear, and then used this gear to drive more gears.

Seeing a large pile of gears drawn by Sun Yu, Huang Yueying's eyes lit up, she also picked up a branch, pointed to a gear drawn by Sun Yu and said: "I know this thing, the last time someone dug up a bronze wheel from four hundred years ago, there was this kind of tooth on the edge, but unfortunately I studied it for a long time and didn't think of what it did." ”

Sun Yu heard this, and thought to himself: gears were invented in 400 to 200 BC, and bronze gears of that era were unearthed in Shanxi, China...... China's ancient magical skills are passed down by word of mouth, so it is a pity that they have been lost.

He smiled and pointed to a gear and said, "This thing is called a gear, and it can change the size or direction of the force." Like what...... I flick a small gear with a big gear, and I can convert the distance traveled into power, and double the distance for double the power...... Of course, my statement is relatively simple, and there is a conversion formula for the specific distance and strength. ”

Huang Yueying was stunned and didn't understand.

Sun Yu smiled: "To put it simply, I can use these gears to make a child push 200 catties of grain." ”

Huang Yueying's face was full of disbelief.

Sun Yu laughed, ignored her, and continued to draw the design drawings on his own.

After a while, Yan Yun bought a large amount of wood, as well as some iron sheets, iron rods, beef tendons and other things. Sun Yu picked up two pieces of wood, beat them with a hammer and chisel, and after a while, made two wooden gears.

In fact, gears should be made of iron to be more durable, and gears made of wood will be damaged after a few times, but Sun Yu doesn't have time to find a blacksmith to slowly build iron gears, so he casually uses wood to play temporarily. People make gears by hand, and the accuracy is very poor, but Sun Yu can't care about so much, anyway, it's for demonstration.

Sun Yu put the two iron rods between the two gears, one large and one small, respectively, and then fixed the two gears together, and then smiled at Huang Yueying: "Let's take a look at the role of the gears first!" ”

He made a rocker on the iron rod of the pinion, and turned it gently, and the pinion rotated with the movement of his hand, and the bite of the two gears made a rattling sound of wood that made my teeth ache, and the big gear immediately followed the pinion.

Sun Yu smiled and said, "Understood?" ”

Huang Yueying shook her head and said, "What is there about turning these two wheels that you don't understand?" ”

Sun Yu laughed and said: "You see, I can drive the big wheel by turning this small wheel hard, but the circumference of the big wheel is longer than the small wheel, that is...... When I'm spinning the little wheels, I just need to put a little more effort into making the wheels spin a little bit more......"

Sun Yu paused, and then said: "On the other hand, if I turn the big wheel to drive the small wheel, I can only turn a little distance and let the pinion turn a few times......

Sun Yu picked up a big stone from the side, put it in front of Xiao Xu Shu and said, "Xiao Shu, try to see if you can hold it." ”

Xiao Xu Shu ignored him.

Huang Yueying hurriedly gave Xiao Xu Shu a look, and Xiao Xu Shu obediently walked over.

She hugged the stone with all her strength and didn't move!

Sun Yu hung the big stone on the big gear with cow tendons, and then pointed to the rocker of the little gear and said to Xiao Xu Shu: "Xiao Shu, you can try to shake this wheel......
