Chapter 579 Machine Cockroach

The machine cockroach in the box is the "good thing" that Shu Xiaoxian wants to show Lin Hong.

Lin Hong took one out of the box and put it in front of his eyes to observe it carefully.

This is a very simple machine. There is a motor and battery in the middle of the body, and the calf made of connecting the motor and steel sticks through the gear transmission.

Overall, it looks like an extremely simple toy for children.

Of course, Lin Hong naturally knows that this thing looks simple, but it is not so easy to make, because there are also some carefully constructed details. For example, the number and distance of gears between these calves are not the same. It's not just like those toy machinery, it's just forward and forward. .

Around this thing, there are several long tentacles that can be folded, connected to a very clever device. Lin Hong can see that as long as the tentacle touches the object, the movement rules of the machine will be changed.

When Lin Hong saw this thing, he couldn't help but think of the competition between robots he saw when he was studying in the United States.

Mark Pauline finally used several small toy cars and almost won the game. Among them, there is an infrared device that Lin Hong helped to improve, which has the same effect as this tentacle.

"Brother Hong, this is the machine cockroach I designed." Shu Xiaoxian introduced, "It has been improved many times before it was finally finalized."

With that, she waved her hand and motioned Lin Hong to come over. When Lin Hong put her ear over, she whispered in his ear, "This design is based on the previous uncle's machine car."

Lin Hongxin said. Sure enough.

The toy car used by Arthur's uncle at the beginning was similar to the current machine cockroach, but the mechanical calf replaced the original roller.

This kind of small cockroach structure is relatively simple and easy to make. They have made a lot, except for those in Shu Xiaoxian's hands. Lin Peng also took out another box from a shelf in the room, which was full of such small things.

Then. They came to a relatively empty room.

This room is usually an experimental site used by the department for special testing. There were originally some obstacles in the site. However, at this time, it has been cleaned aside, with a baffle in the middle.

With the assistance of Lin Peng, Shu Xiaoxian began to show Lin Hong the mechanical cockroach she designed and invented.

After starting the switch, the small motor began to rotate slowly, and the thick calves of the six matchsticks also began to sway, put them on the ground, and it began to move forward.

I can't see that this machine cockroach is quite flexible and does not move slowly, after a while. Then he touched the wall, then stepped back a few steps, turned in one direction and began to move.

Lin Peng said, "A machine cockroach can't see anything. It needs a group of people. It's very interesting."

said. He began to start the switches of these cockroaches one by one and let them out one by one.

Lin Hong kind of guessed the meaning of his words, and also squatted down to help start these little things together.

In a short time, the whole field was covered with this kind of small machine cockroach, and they were pattering around the field. It's messy.

saw them moving in the original direction, and finally touched the baffle, and then it stopped, adjusted an angle, and then continued to move forward.

If you encounter other machine cockroaches in the middle, the same is true of the decision they make. Stop, adjust the direction, and move forward.

There was a very noisy sound in my ear. I didn't feel the footsteps of a machine cockroach, but when the footsteps of these machine cockroaches overlapped, the whole site was full of this sound, just like the sound of mosquitoes.

However, this messy state did not last long. Soon, Lin Hong saw that the cockroaches in the field gradually formed a stream of insects, and their movements began to become regular. Whether they were moving forward or turning, their movements became neat and uniform, as if there was a man giving orders in a unified way. Induct them to make some kind of action.

Lin Hong seemed to really see a group of cockroaches, forming a stream of insects, running left and right in the middle of the field.

Seeing this situation, Lin Hong couldn't help but have doubts in his heart.

What is the reason why they finally formed the current state?

In his mind, a scene of beeswarms, birds and fish came to his mind.

The movement of the swarm usually forms a seemingly chaotic mass, and then moves as a whole, but this kind of cluster can keep the internal orderly. Originally, many people thought that in the middle of the swarm, there must be a key bee leader in commanding their actions, but according to the latest research and observation results, there is no such special bee in the middle of the swarm, as if there is an invisible hand directing their actions.

The same is true of the birds in the air and the fish in the sea.

Thousands of birds or fish can form a huge three-dimensional sphere, ribbon, and other strange shapes.

The whole group seems to be disorganized, but in fact it follows an extremely accurate rule. Between birds and birds, between swimming fish and swimming fish, it always keeps a certain distance. Even if it turns quickly, it will not collide, which is shockingly accurate.

Just as plant growth follows a certain law of nature, this aggregation of animals also seems to have a certain undiscovered rule.

Many scientists are studying these topics and have achieved a lot of results so far, putting forward a concept of "group intelligence". The core idea is that individual animals may have limited intelligence, but when they gather together, they will form a magical intelligent phenomenon and can make corresponding decisions, which is often the best choice.

Lin Hong also knew something about this area before, but he did not conduct in-depth research.

This time, Shu Xiaoxian gave him a big surprise. He never knew that in addition to animals, there was also such a phenomenon in machinery.

The scene in front of him tells him that between these mechanical cockroaches, an inexplicable group intelligence has formed, which finally formed such a regular insect flow.

Lin Peng next to

may just think this phenomenon is amazing, and Shu Xiaoxian may just think it's fun, but Lin Hong sees something unusual from it.

Lin Hongzan said, "It's very interesting, Xiaoxian, this kind of mechanical cockroach is designed by you?"

Shu Xiaoxian's small body stood up: "Yes, but other brothers in the department have also helped me a lot."

"How do you think of doing such a thing?" Lin Hong was a little puzzled.

"Actually, this is a by-product of my guide robot." Shu Xiaoxian said with a little embarrassment, "But that kind of robot is too complicated for me to do it. Later, I thought of you... The robot car you told me about last time, so I got this inspiration."

Shu Xiaoxian originally wanted to say that she had seen the content in Lin Hong's memory, but when she thought of someone next to her, she immediately changed her words.

In fact, many of the machine cockroaches she designed borrowed from the original car, especially the concept of tentacles. It was because she was not familiar with infrared wireless and could not make such an effect, so she finally retreated and chose this scheme.

In the end, Shu Xiaoxian did not know the specific meaning of the effect, but at the beginning, it was fun to put a lot of machine cockroaches together, and as a result, she saw this phenomenon.

Although Shu Xiaoxian learned a lot about electronics and design with Lin Hong's memory, she is still young after all. Things in terms of vision and way of thinking are not only obtained through reading and learning memory, but must be accumulated for a long time.

Lin Peng said, "The machine cockroach designed by Xiaoxian has given a lot of inspiration to the lunar rover research and development team. Previously, in order to allow the lunar rover to adapt to the complex terrain, they wanted to replace the wheels of the lunar rover with mechanical legs, but in the end, they were stuck on the control system. It was a huge problem to control six legs at the same time to maintain a balance. Later, Xiaoxian's machine cockroach made them understand that the control mechanism of the legs did not need to be so complicated, but only needed to be responsible for lifting and lowering.

For robots or other mechanical devices, the usual design idea is that there is a control system to control these devices globally and accurate to each joint. Naturally, this requires a very powerful system. Although it is easy for animals to control their legs, robots are not so simple to achieve mechanical leg walking. There are too many technologies and algorithms involved.

The previous "Mars rover" used wheels, but now the lunar rover research and development team wants to replace it with mechanical legs, so naturally it is not just a change. They have tested many versions, but in the end they are stuck here and can't move.

And Shu Xiaoxian used a simple mechanism to solve this problem, making everyone's eyes fall to the ground.

Of course, small machinery and large machinery are still different and cannot be copied, but this design idea has given them a lot of inspiration.

Lin Hong picked up the machine cockroach from the ground again and looked at it carefully.

Strictly speaking, this is not an electronic product. Except for the motor, it is composed of mechanical devices.

That is to say, there is no key part of the brain to control these machine cockroaches, and they finally reached a tacit understanding in the chaotic action.

Simple rules can bring unexpected group wisdom.

Lin Hong has known this for a long time, but he never thought that this principle could be established in the mechanical field.

I have to say that this is an unexpected surprise brought to him by Shu Xiaoxian.

Lin Hong would like to know that if this mechanical cockroach is improved and some of his own ideas and technologies are added, what more interesting phenomena will happen in the end? To be continued) RQ
