I don't know when it started, Guangdong and "Xiao Qiang" formed an indissoluble relationship.
The first impression of foreign friends coming to Guangdong is not food, not humanities, not scenery, but - cockroaches that disappear in the night and seem to be everywhere.
It is not surprising, after all, Guangdong's largest airport: Baiyun Airport, is designed with cockroaches as inspiration, who sees it and does not call the insider?
Just kidding, this topic that was once on the hot search, Guangzhou Baiyun Airport once personally came forward to explain: the design of Baiyun Airport is the concept of the central airport, and it is also the first in the country to do so.
Or maybe cockroaches, like herbal tea, have been carved into the DNA of Cantonese people like Guozi: we look like cockroaches.
If one day someone suddenly finds out that the cockroaches have evolved into cybertrons, it is difficult to say whether this is a surprise or a fright.
But unfortunately, it's true.
Let the fruit drink a cup of herbal tea to calm the mind, and then talk to the fox friends.
Recently, a team at the Riken Institute of Chemistry in Japan designed a system that can make remotely controlled semi-mechanical cockroaches.
So why charge this thing? Give electronic xiaoqiang a five blessings and an annum の safe fast charge?
Unexpectedly, they designed a miniature wireless control module that can be charged by solar energy. Not only can it be self-powered, this ultra-thin electronic device and flexible material, but it can also allow this semi-mechanical cockroach to move freely and release its nature.
The team says their cyborg cockroach design may be able to make it possible to apply cyborg insects in real life.
When I think of it, our lives in the future may be filled with mechanical cockroaches, mechanical spiders, mechanical mosquitoes... I couldn't help but shiver.
How did such a (ke) into (pa) technology get made?
The research team said that putting these delicate devices on Xiao Qiang's "petite" body made a lot of effort. They developed special "backpacks," ultra-thin organic solar modules, and adhesion systems that guarantee the free movement of mechanical cockroaches.
On this basis, the research team selected a Malagasy cockroach about six centimeters long as the lucky one... Oh no lucky mantis, take advantage of this specially designed cockroach model backpack that attaches a wireless leg control component and lithium polymer to the top of the chest.
Specifically, the backpack is 3D printed with an elastic polymer, which is warm and close to the body, and cockroaches can wear it for more than a month.
If there is no electricity, it is all in vain, so power supply is very important. This time, the ultra-thin organic solar module is only 0.004 mm thick and has an output power of 17.2 milliwatts, and is placed on the dorsal side of the abdomen of the "Lucky Mantis".
With the double blessing of ultra-thin and flexible solar cells and reasonable attachment methods, cyborg cockroaches can move freely for a long time.
The research team also said that this is not an exclusive benefit of Xiao Qiang. This design can be adapted to other insects such as beetles, and even flying insects such as cicadas.
After reading these research materials, Guozi had to sigh: In front of the Japanese, our Cantonese people's "love" for cockroaches is so superficial:
They worked hard to remake cockroaches, armed to the teeth; And we just want to use slippers to make cockroaches become two-dimensional.
They really... I cried to death.
Out of curiosity, Guozi went to Baidu again, only to find out: this is not the first time about cockroach transformation.
As early as 2021, someone in Nanyang Technological University in Singapore tried to install a small computer chip equipped with an infrared camera, carbon dioxide sensor, temperature and humidity sensor on the cockroach. Cockroaches are controlled remotely to point out where to fight.
There may be foxes who wonder: there are so many insects in the world, why do you have to use cockroaches? Is it because these foreigners have the same Cantonese DNA as the fruit?
No, there is a scientific basis for choosing cockroaches.
The cockroach can be controlled by electrical stimulation of nerves, neuromuscular or sensory positions, and the energy of its activity is also provided by itself, so the overall "endurance" of the cyborg cockroach is longer than that of conventional robots of the same small size.
To see clearly, the tail of this Madagascar cockroach is implanted with electrodes, and the current is transmitted through the electrodes to the two tail whiskers, which can cause rotation. When the left tail hair is stimulated, the cockroach will turn to the right, and vice versa.
So you can control the direction in which the cockroach moves by changing the current, just like rowing a boat with an oar.
Humans spend so much effort to make this kind of cyborg cockroach, what is the picture?
The prevailing consensus is to detect hazardous areas, the surrounding environment, and search and rescue missions.
It is easy to understand the detection of dangerous areas, open a brain hole:
What are the ceiling ventilation passages with bombs, the abandoned mines, the buildings where the gangsters lurk... Such areas that people cannot reach or need to sneak into can let the cyborg cockroaches explore first.
That...... How did a little cockroach save a giant human being?
By connecting a microcontroller and an infrared camera guided by a custom machine learning model to a cockroach, combined with custom control algorithms and the insect's own navigation capabilities, the cyborg cockroach can explore complex terrain and detect and find humans in environments such as collapsed buildings.
These are all semi-mechanical cockroaches, so are there "all-mechanical cockroaches"?
Don't you say, there really is... That is, miniature robots created by imitating the characteristics of cockroaches.
It is 3cm long, 1.5cm wide, weighs 0.024g, and operates at a minimum voltage of only 8V.
But it is such a small thing that is as tenacious as a real cockroach:
Take a weight of 100g and press it down, for it is "wet and wet".
The 119-pound adult gave it a kick, or it was fine, this weight is already 2.48 million times its own.
Not only is it stress-resistant, but you can also be a porter and move things that weigh six times as much.
Not only can you walk on flat ground, but you can also climb a 7.5-degree slope.
Compared with the previous "cyborg cockroach", this bionic cockroach robot is not as flexible as a real creature, but it is also more secretive.
If it is used for military purposes... Good fellow, that's really a good helper for a detective like Bond.
In any case, these latest scientific studies on cockroaches have stunned the fruit: the cockroaches that are usually eliminated quickly can still have such a great use.
Of course, if you see a cockroach, the fruit will not hesitate to pass by with a slipper: the fruit never wants to recall the picture of a cockroach crawling on the toothbrush.
