When the U.S. military searched for the wreckage of a Malaysia Airlines passenger plane in 2014, the "tuna" dispatched was an automatic type. Pen & Fun & Pavilion www.biquge.info

However, these two types of unmanned underwater vehicles will also involve six major technologies, including bionics, intelligent control, underwater target detection and identification, underwater navigation (positioning), communication, and energy systems.

Therefore, underwater robots are a kind of technology-intensive and systematic engineering, with a very high threshold.

Therefore, it has also been in the field of military industry, and consumer-grade products have only appeared in recent years.

To a certain extent, it is more difficult to "catch turtles in the five oceans" than to "go to the moon in nine days", because if the underwater robot wants to go underwater, the first thing that needs to be solved is the problem of the robot's "survival" underwater, and its hardware level has high requirements.

In addition to keeping the machine airtight, it is also necessary to prevent corrosion and water pressure.

In addition, in order for the robot to be able to play underwater in a balanced way, it also needs to keep its center of gravity in the same position as the buoyancy center.

What directly affects the intelligence level of the robot is its control technology - the brain and nerve center system of the robot, which is the integration of various artificial intelligence technologies and control technology.

After the robot detects and identifies targets underwater, it can provide effective resource management and feedback.

At present, most of the underwater robots seen on the market are only a combination of "machine" and "electricity", which is an electromechanical system, which can only be called "underwater intelligent machine", not "underwater intelligent robot".

However, with the development of deep learning technology, the intelligence of underwater robots is also constantly improving.

For now, underwater robots are just a tool to extend the human arm, and since they are tools, collecting data and information is their top priority.

At present, the mainstream communication methods of underwater robots mainly include optical fiber communication (mainly used in remote control robots) and underwater acoustic communication (mainly used in autonomous robots).

Optical fiber communication is mainly composed of three parts: optical transceiver (water surface), underwater optical transceiver, and optical cable, which has the advantage of high data rate and good anti-interference ability; The disadvantage is that it limits the working distance and maneuverability of the underwater robot, since it is generally cabled.

Since the working area of the underwater robot is in the water, the products on the market are basically designed with bionic technology.

The underwater robot designed by Mo Ye is also designed based on bionics, after all, there are too many defects in humanoid robots, so Mo Ye finally adopted the shape design of spider crabs.

The reason for this is that the design and implementation of the eight-legged spider bionic robot have already been done.

If Mo Ye was allowed to study from scratch, it would not be impossible for him to do it, but it would take too much time.

If the assembly is redesigned on the basis of the existing scientific research level, there is no difficulty.

Now countries around the world have a lot of research on various robots, as long as Mo Ye selects some of them, optimizes and reorganizes, you can get a more satisfactory product.

For example, the underwater spider crab eight-legged robot he designed came about in this way.

The most difficult control program for others is precisely the simplest part for Mo Ye, as long as a set of primary intelligent operating systems is installed, this problem can be perfectly solved.

Therefore, for Mo Ye, whether it is a drone or an underwater robot, what bothers him is energy, that is, its endurance.

However, the cutting-edge technology that Mo Xie spent several years collecting was not done in vain, so he still found several more satisfactory design schemes.

At present, there are mainly several types of self-living underwater robots designed by countries around the world, such as fish, shrimp, humanoids, jellyfish, etc.

Among them, each one has its own advantages, Mo Xie is to make up for the shortcomings, and finally adopt the shape of a spider crab.

The eight-legged ensures stability, and also ensures that its main body can be larger, so the back of the spider crab can be installed with computing units, batteries, and thrusters.

The spider crab bionic robot can detect underwater mineral deposits, with two specially designed tentacles to detect obstacles in the environment, and eight legs that can move in any direction.

With 11 infrared light-emitting diodes built into the dome structure, they can communicate with each other.

In this way, as long as the number is large and the distance is close, a stable communication network can be formed to achieve underwater barrier-free communication.

The spider crab bionic robot also supports 2 million pixel video recording, and also has a multi-function suspension point, which can be easily hung on the bottom of the ship.

In addition to these functions, it can also be equipped with 3D cameras, sonars, robots, optical fibers, and other equipment.

And the most important thing is that this spider crab bionic robot can rely on the wave and the battery to provide driving energy, and can use the wave to generate propulsion underwater, with a maximum speed of 5.5 kilometers per hour.

It can be operated stand-alone or integrated into a fleet to transmit data in real time, and can run for an entire year without any fuel.

Such an underwater robot is enough to use, after all, under water, there is no need to move too fast, and there are no enemies.

Therefore, compared with land robots, underwater robots are still a little simpler.

There has been a design plan for a long time, what Mo Xie lacks is all kinds of components, and now he has money, plus he has his own fleet, which can operate the buying and selling of sensitive components, so the batch of machine construction that Mo Xie wants recently has all been in place.

As long as the underwater robot is in accordance with the design plan, the standard parts are made, assembled and debugged, and the main problem is compatibility, as long as there is no compatibility problem, even if the design and production are successful.

Land robots are different, compared with underwater robots to consider the problem of communication, land robots need to consider more problems, such as communication, load-bearing, endurance, speed, stability and so on.

Communication is the easiest, load and endurance are inversely proportional, of course, speed and load are also inversely proportional, and stability is the best solution.

Load, endurance and speed, in the final analysis, is energy, which relies on the current technology, almost no solution, and stability, now there is a good solution, such as the robot that does not fall, as long as the design is reasonable, the magic machine will balance itself, and it can't be pushed down at all!

The principle is actually very simple, simply understood as any object will produce an effect of stabilizing the axis of rotation when rotating, for example, the spinning top cannot stand still, but once it rotates, it can stand firmly, and the faster and more stable.

This is the embodiment of the law of conservation of angular momentum, when designing a robot, as long as the normal direction of the three perpendicular surfaces is stabilized by the flywheel, so that it can achieve considerable stability in three-dimensional space.

Stability can be supported by hexapods, agility and dexterity are not difficult to solve, and now the main thing is mobility.

In fact, many large robot companies have solutions to the above problems, such as the robot dog developed by the U.S. military, the main problem is the noise generated by its power system, maybe they use diesel engine power, so the noise can keep up with the diesel engine.

"If the engine technology is used, it is better to make it directly into a model robot!"

After a busy night, he didn't think about how to solve the power problem, and Mo Ye could only give up in the end.

The most mature robot on land must be a model robot, and a foreign bull who manufactures industrial robots seems to have been acquired by a domestic company recently!

It is one of the world's top industrial robot manufacturers, and his robots are everywhere in all the factories at home and abroad.

In the popular short film "The Shock of German Industry 4.0", more than 90% of the work in BMW's unmanned factory is done by robots.

And now, many manufacturing companies and OEM companies are all carrying out robot transformation, because the labor cost is too high, so they want to replace humans with robots.

Not to mention anything else, the express automatic packaging and sorting system released by an online sales platform recently is more bullish, and these are the beginning of intelligence.

"There are fewer workers, welfare benefits will be increased, more workers, it is a sweatshop, it will be exploited, and now the wages of workers have finally increased a little, those capitalists actually want to eliminate workers, all with robots that work hard and complain 24 hours a day?"

Thinking of this, Mo Xie was dejected and sealed all the information he had searched for in the corner.

Intelligence is the general trend, but the speed can not be too fast, if immediately enter the era of intelligent robots, then what are the nearly 200 million migrant workers in China to do?

"It's still the disadvantage of education industrialization, if all of them are college graduates, as long as they have a little training, they can train qualified technicians!"

Intelligent factories require a large number of maintenance personnel, and without culture, it is naturally not easy to learn technology.

"In the final analysis, the problem of talent is still a problem of education, which is a dead cycle!"

I couldn't figure it out, Mo Ye simply took a shower and went to sleep, and when he woke up, he was refreshed again.

Walking out of the house and getting in the car, Mo Xie planned to go to the school for a walk, after all, it had been two months since he came out, and he was not a good student.

"Who's this? Why do I look like Boss Mo? How do you have time to come to school? As soon as he entered the school gate, Mo Xie heard a yin and yang strange voice, needless to say, the one who could talk to Mo Ye like this must be Comrade Zhao Xinhua.

"Lao Zhao! How do you have time to go out? Hey, this is going to buy groceries in person? Mo Xie said with a hippie smile.

"I even go to the toilet myself!" Zhao Xinhua said angrily.

"What are you angry about! I did it in strict accordance with the school's regulations, and I completed all the tasks assigned by the school! Mo Xie said with a smile.

Zhao Xinhua sighed and said: "It's because it's done so well that I'm angry, you go and take a look now, see how many people in our class still go to class?" There are also senior classes, and professors can rest at home! ”
