The robot cockroach in the box is the "good thing" that Shu Xiaoxian wants to show to Lin Hong. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

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

It is a very simple machine, with a motor and battery in the center of its body, and a gear drive that connects the motor to the legs made of steel rods.

Overall, it looks like a very simple child's toy.

Of course, Lin Hong naturally knows that this thing looks simple, but it is not so easy to make, because there are some carefully constructed details in it, for example, the number of gears and the distance between these calves are not the same, and it is not like those toy machines, which are simply forward and forward.

Around this thing, there are also a few long tentacles that can be folded, connected to a very ingenious device, Lin Hong can see that as long as this tentacle touches the object, it will change the rules of movement of this machine.

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 almost wins the race with a few small toy cars, including an infrared device that Lin Hong helped improve, which works like the tentacles.

"Brother Hong, this is the robot cockroach I designed." Shu Xiaoxian introduced, "It was improved many times before it was finalized. ”

As she spoke, she beckoned and motioned for Lin Hong to come over, and when Lin Hong leaned her ear over, she whispered in his ear: "This design refers to the previous uncle's machine car." ”

Lin Hong said in his heart. And so it was.

The toy car used by Arthur's uncle was similar to the current robot cockroach, except that the original wheels were replaced by mechanical legs.

This kind of small cockroach has a relatively simple structure and is easy to make, and they have made a lot of them, except for these 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 used as an experimental site for testing in the department, and there were originally some obstacles in the field. However, at this time, they have all been cleaned aside, and there is a baffle in the middle.

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

After activating the switch, the small motor began to rotate slowly, and the six matchstick-sized calves began to sway up and down, and when it was lowered to the ground, it began to move forward.

I can't see that this machine cockroach is quite flexible, and it doesn't move slowly, after a while. He touched the wall, then took a few steps back, turned in one direction and started moving.

Lin Peng said: "A robot cockroach can't see anything, it has to be a group, it's very interesting." ”

said. He began to turn on the switches of the cockroaches one by one, releasing them one by one.

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

After a while, the entire center of the field was covered with these small robotic cockroaches, and they were jumping around the field. Be scatterbrained.

They moved in the same direction, eventually hitting the baffle, and then it stopped, adjusted an angle, and continued forward.

If you run into other machine cockroaches in the middle, they make the same decision, stop, adjust the direction, and move on.

There was a very noisy sound in my ears, and the footsteps of a robot cockroach did not feel anything, but when the footsteps of these robot cockroaches overlapped, it was like the cry of a mosquito, and the whole venue was filled with this sound.

However, this chaotic state did not last long, and soon, Lin Hong saw that the cockroaches in the field gradually formed a stream of insects, and their movements began to become regular, whether it was advancing or turning, the movements became uniform, as if there was a person giving orders in unison, directing them to make a certain action in unison.

Lin Hong seemed to have really seen a group of cockroaches, forming a stream of insects, rushing left and right in the field.

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

What is it that led them to the state they are in?

In his mind, a swarm of bees, birds, and fish came to mind.

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

The same goes for flocks of birds in the air and schools of fish in the sea.

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

The whole group seems to be disorganized, but in fact it follows an extremely precise rule, and the birds and birds, and between the swimming fish, always maintain a certain distance, even if they make sharp turns, they will not collide, which is shockingly accurate.

Just as plants grow according to a certain law of nature, this aggregation of animals also seems to have some kind of law that has not yet been discovered.

Many scientists have been working on these topics, and many achievements have been made, proposing the concept of "group intelligence". The core idea is that individual animals may have limited intelligence, but when they are gathered, they form a magical intelligence phenomenon and can make corresponding decisions, which are often the best choice.

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

This time, it was Shu Xiaoxian who gave him a big surprise, he never knew that in addition to animals, even in machinery this phenomenon exists.

The scene in front of him told him that among these mechanical cockroaches, an inexplicable group wisdom was formed, and such a regular flow of insects was finally formed.

Lin Peng next to him may just think this phenomenon is amazing, and Shu Xiaoxian may just think it's funny, but Lin Hong saw something unusual from it.

Lin Hong praised: "Very interesting thing, Xiaoxian, this mechanical cockroach, you designed it?" ”

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

"How did you come up with the idea of making something like this?" Lin Hong was a little puzzled.

"Actually, it's a by-product of my blind guide robot." Shu Xiaoxian said a little embarrassed, "But that kind of robot is too complicated, I can't do it, and then I remembered you...... The robot car you told me about last time was inspired by this. ”

Shu Xiaoxian originally wanted to say that she had seen the content in Lin Hong's memory, but as soon as she remembered that there was someone next to her, she immediately changed her words.

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

In the end, Shu Xiaoxian didn't know the specific meaning of the effect, but it was fun at the beginning, putting a lot of machine cockroaches together, and she saw this phenomenon.

Although Shu Xiaoxian has learned a lot of knowledge about electronic appliances and design with Lin Hong's memory, she is still young after all, and things in terms of vision and way of thinking about problems cannot be obtained only through reading and learning and memorization, but must be accumulated for a long time.

Lin Peng said on the side: "The machine cockroach designed by Xiaoxian gave the lunar rover R&D team a lot of inspiration. 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, and it was a huge problem to control the six legs at the same time to maintain a balance and move forward. Later, Xiaoxian's robot cockroach made them understand that the control mechanism of the legs does not need to be so complicated, and they only need to be responsible for lifting and lowering. ”

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

The previous "Mars rover" used wheels, but now the R&D team of the lunar rover wants to replace it with mechanical legs, which is naturally not just a change. They tested many versions and ended up stuck here and couldn't move.

And Shu Xiaoxian solved this problem by using a simple mechanism, which made everyone's eyes fall to the ground.

Of course, there are still differences between small machines and big machines, and they can't be copied, but this design idea has given them a lot of inspiration.

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

Strictly speaking, this is not an electronic product, except for the motor, everything else is made up of mechanical devices.

In other words, there is no key part of the brain that controls these robot cockroaches, and in the midst of their chaotic actions, they finally reach a tacit understanding.

Simple rules can lead to unexpected crowd intelligence.

Lin Hong has known this for a long time, but he never thought that in the field of machinery, this principle can also be established.

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

Lin Hong wanted to know, if this mechanical cockroach was improved and some of his own ideas and techniques were added, what more interesting phenomena would happen in the end? (To be continued)
