Many people have the mentality of attracting others' attention. Whether they read the news or other articles, many people like to write a few comments, regardless of whether they write them correctly or not. Some people know that the comments they write and may cause others to scold, but they still enjoy writing them. These criticized comments are not rewarded for a penny.

Now Peng Huading and his friends offer so much reward for this website, so there is no registration fee, there is no qualification review, and there is no strict requirement, so naturally many people are willing to write a few sentences.

Of course, there are also many people who want to scold them.

"The website is boring, and it's famous by such a bad hype. Is it interesting? Your mother called you back for dinner."

"Looking at the reward notice above, I felt a sense of super IQ in my heart."

"Really and false? This society is speechless. I find that I don't even dare to say that it is true or false."

"Upstairs SB! You can't even tell the true or false of such a child's trick. Are you afraid of lowering the human IQ?"

"The upstairs is even more sandwiched between sa and sc. Are you insulting the child? Now the child is much smarter than you."

"Similar, now you can attract a beautiful girl to slap your knives and bed with you, but you can try to trick the little girl into watching goldfish with lollipops?"

"I'm a soy sauce."

"Brother sat on a small bench and was watching the fun."

"+1. However, it seems that a natural beauty doesn't need any lollipops, right?"

"One thousand yuan is not bad, you can do several foot massages."

...

However, although there are many sour messages, many people still secretly write down their ideas and ideas and send them out.

Many of the people who send these messages have the mentality of giving it a try. It doesn’t matter if you hit it or not, it just wastes a few minutes. What if the website says it is true, and this kind of submission is kept confidential and does not lose face.

In Yunfeng Technology Company, Peng Huading, Xie Zhanfeng and Tan Jinhu are studying the power of snake-shaped robots. The so-called research is actually inspiration, which means that Peng Huading constantly extracts some creative suggestions from various submissions received by the website and makes them think about it. Let them agree.

When their opinions tend to agree, that is, they are finally pulled to the correct point of view by themselves, Peng Huading recorded it in the wisdom of the collective. When their opinions are not unified, or they do not understand the suggestions they make, Peng Huading shows that he is the boss and the style of the immediate boss forcing them.

In a word, the two new college students had to follow Peng Huading's baton. However, Peng Huading's work was not so explicit, which made them feel that the design of this snake-shaped robot was really discussed, as if they were inspired by their creation. Many of their creativity were extracted from the suggestions collected on the website.

Peng Huading drew a sketch on the drawing board and said, "Tell me what you think we should define the walking mechanism of the snake robot as. Xie Zhanfeng, you are the main person in charge of this project, you can talk first."

Xie Zhanfeng fixed the sketch he drew to the drawing board with a circular magnet and said, "I thought about it over and over again, but I thought it would be better to adopt a track-like walking mechanism. Why? Because I think the working environment of the snake robot is very harsh. It is not walking on the flat ground. It has to climb a rugged path. It has to enter a hole in the ground and climb a tree branch. If it is a wheeled mechanism, there is no crawling force at all. The wheeled mechanism is good on the flat ground, but on the rugged path, there is no power in the hole in the ground.

As for the track you are worried about is difficult to connect with its soft body, I think this is your thoughts and you have entered a dead end, thinking that the entire snake robot must be pressed on the track. This will naturally cause great difficulties for us to install. Especially, it cannot be firmly connected in the front of the body at all. My suggestion is to only adopt a small section of tracks at the front of its body, which is symmetrically distributed, and then drag the way behind it. In this way, the installation problem will be solved."

The graphics he showed no longer look like a snake, but more like a catfish, or a tadpole that was extended and enlarged.

Seeing that Tan Jinhu was about to laugh, Xie Zhanfeng said: "The purpose of making this robot is to be useful, not to emphasize that it must be snake-shaped. Since my robot can complete the work of a snake-shaped robot, why not? I checked that the robot designed by the famous university in our country is just a concept and cannot achieve practical effects. Their method of moving frames is too large, and a lot of energy is consumed on unnecessary movement of the extracted metal frame. The energy used for its movement is less than 10%, so it runs for a short time and cannot achieve practical possibilities at all. Unless the so-called metal battery is invented in the future, the battery has a very high energy density."

Peng Huading smiled and said to Tan Jinhu: "Do you still think your wheeled walking mechanism is good?"

Tan Jinhu said: "Yes. I think the wheeled mechanism is light, simple to manufacture, and has a low failure rate. From our daily life, we can see that there are very few crawlers, only tanks, self-propelled artillery, etc., only a small number of tractors and mobile cranes, and most of the walking equipment is wheeled, such as cars, trains, and even robots on the moon, they also use wheeled mechanisms.

Xie Zhanfeng just said that the crawling force of the wheeled mechanism is small, which means that because the snake-shaped robot is light in weight, the friction with the ground is small if it adopts a wheeled walking mechanism. In fact, we can use other methods to solve it. Just like the lunar robot, we adopt the metal skeleton like a wheel, and even install sharp spikes on the wheel to increase friction.

The advantage of adopting a wheeled walking mechanism is obvious, that is, it is convenient to purchase a power mechanism, and you only need to purchase a micro motor. The most prominent advantage is that you can install wheels on both sides of the snake body instead of dragging the car in the second half. It greatly improves its movement speed and load capacity."

After they finished speaking, Peng Huading said, "You both have worked hard for several days, but I think your horizons are still not broad and you can't see far. You are still constantly strengthening yourself to connect the walking of the snake robot with the objects around us. You have not carefully studied how to use the characteristics of the snake. We either don't do it now, and of course we do the best, rather than pursuing the completion of this task to achieve this task.

You already know the three forms of movement of snakes, that is, the first winding movement, which is the snake body that is horizontally wavy bends on the plane, and the back of the bend of the snake body is exerted on the rough ground, which is equivalent to a person standing on the boat to support a bamboo pole, and relying on the reaction force at the bottom of the water to push the hull forward, while the snake uses the reaction of the muscles at the bend to push the snake body forward.

The second type is dragon boat-like movement. The snake's ribs can be swayed forward and backward around the spine under the drag of the muscles. There is a ribbed skin muscle between the ribs and the abdominal scales. When part of the ribbed skin muscle contracts, the ribs connected to the connected part will be lifted and moved forward. The abdominal scales attached to it are relaxed at this time and will also move with the previous one.

Then the rib skin muscle lowers the ribs and exerts the force on the ground with the posterior edge of the abdominal scales. When the other rib skin muscle contracts, the ribs move backwards and pushes forward against the ground, while the other part of the ribs breaks away from the ground.

This way, some of the ribs are lifted forward, and some of the ribs pressed against the ground and backward, and the snake keeps moving forward.

If the former movement method is equivalent to standing on a boat and supporting a bamboo pole, then this movement method is equivalent to rowing a dragon boat. The athletes on the dragon boat are equivalent to the ribs of a snake, and the oars in their hands are equivalent to the rib skin muscles of a snake.

The third way of movement is to stretch and contract. When moving forward, the front half of the snake suddenly stretches out. After this part touches the ground, it immediately presses it. Other parts of the body are supported and move forward in the snake's skin. This method is equivalent to a gymnast playing a balance beam. First, extending out your hands and pressing it on the balance beam, the body is suspended under the action of both hands, and then the body moves forward under the action of muscles throughout the body. This way of movement not only has this function, but also earthworms and soft caterpillars. They play this action of pressing and hanging again and moving forward again.

Many of the books you see in the books that introduce snake movement are wrong, or these books are very mysterious, partly correct and partly wrong, so they restrict your imagination and creativity. Now that I have explained the principle of snake movement clearly, we will discuss how to achieve these three ways of movement, or whether we adopt all three ways of movement or only one or two of them."

After Peng Huading said this vividly, Xie Zhanfeng and Tan Jinhu all understood a lot in their hearts, and they were no longer the sceptical concepts when reading books. In particular, Peng Huading decomposed the snake's movement into a bamboo pole, rowing a dragon boat, and the athletes moved on the balance beam, which made them feel very vivid, very easy to understand, and it was easier to think about how to use mechanical methods to achieve these three movements.

Xie Zhanfeng immediately said: "Boss, I think we can achieve the easy first, so we focus on one kind of movement, that is, dragon boat-style movement. Because the winding movement requires too high flexibility on the entire mechanism, we cannot achieve it for the time being, and I can't find a good way for the moment. The telescopic and similar movement have high requirements for the entire robot. The inner cavity must have several layers, and the snake's muscles can flexibly stretch and shrink, but our materials cannot do it for the time being, at most, fold and relax. It takes up a lot of places, and it also makes the robot easy to loosen."
