In fact, these eight lunar rovers are all remote-controlled lunar rovers, and now only two of them are used for testing.

In other words, they don't really have to climb step by step, and if there is a more valuable research target nearby, they can quickly run over to study.

It is no longer the time for human beings to first touch the moon, and not every centimeter of the lunar surface is worth studying, but due to the speed limitations of unmanned lunar rovers, scientists can only play this "carpet" scientific research.

Of course, it would be better if "carpet" and "run" could be combined.

No, eight new lunar rovers of the Navigator are coming.

In fact, this remote-controlled lunar rover is very similar to the way Merrican's previous manned lunar rover moves, requiring human hands, eyes, and brains to make quick judgments, rather than slow calculations by computers.

Why can a manned lunar rover reach 17 km/h?

It's because there's a driver driving it.

If there are pits, rocks, or aliens ahead, the driver can make a judgment as quickly as he does on Earth, and then drive over, bypass, or stop.

If the direction of progress is basically flat, with only small ups and downs, no deep craters, and no large boulders, just use the "super speed" of 17 kilometers per hour to fly over.

The same is basically the case with remote-controlled cars, the difference is that there is a manned driver on the spot, and there is no delay. And the driver of the RC car on Earth, there is a delay.

Therefore, the speed of the RC car is limited to 10 km/h, and the usual use is even more than 5 km/h.

It's just to give the driver enough time to react.

If the remote pilot sees dangerous craters and large rocks ahead, and the data given by the probe is seven meters, then the driver can remotely control the lunar rover to stop even if there is a delay.

So if you want to play RC cars, you need to have several conditions.

First of all, the detection system should be sensitive and fast, and it can quickly give the distance and size of a more conspicuous target, mainly to measure the "depression" and "bulge".

The previous equipment was not good, and the accuracy and speed were not up to it, but now it is not a big problem.

Then there is the appropriate speed limit and extended reaction time, which has been mentioned earlier.

Then there's the driver's problem.

In addition to the need for the eyes and reactions of a normal driver, it is also necessary to be able to anticipate.

Needless to say, the driver must have this, that is, there is a stone or pit in front of you, you have to judge how far away they are from you, and then you can react quickly.

And the prediction is the unique skill of the driver of the lunar remote control car, because what they have to fight is the delay of the Earth-Moon communication.

If the driver on the earth finds that there is a pit in front of him and finds it in time, then he does not need to make a sharp turn, and can slowly turn a large arc to ensure the stability of the vehicle.

If you find something wrong, it has actually been more than a second, and when you make a move, it will take more than a second to transmit it to the lunar rover.

So when you feel like you can turn a corner, it's actually too late, and you should stop immediately.

Fortunately, the speed of the lunar rover is not fast, it is impossible to be like the earth car, it is tens or 100 kilometers at a time, and its general speed is only five kilometers per hour.

The requirements are not too high.

Of course, the driver will definitely have to be trained, and the better the better, because it also retains a speed of 10 kilometers per hour, which will be unlocked if there is really a "predictive flow" of old drivers.

If it is an ordinary remote control driver, it must be braking most of the time, which seriously affects the detection speed.

Tang Chao felt good.

After the results of a 10-meter test came out, he set a target of 50 meters for the second time.

This time it was also easy, the road surface was relatively flat, and no craters and rocks of dangerous size were found, so it was completed quickly.

After 100 meters, 200 meters, and 500 meters, Tang Chao and another driver drove more and more smoothly, passing in a straight line, bypassing, stopping, turning, and starting again......

Because it's time to test the handling, I don't think about scientific research, so I'll run for a while.

The speed of 5 kilometers per hour gave them the feeling of driving a formula 1 car.

Especially when another car followed behind him, the scene was very shocking.

Even if the small wheel only travels 1.39 meters per second, it turns quite fast, and the lunar soil it brings up is thrown high and falls quickly, and it can fly far away.

That's called a spectacular.

The audience also screamed.

【Cattle Batch!! 】

[It really worked!] 】

[If this is the case, combined with those slow unmanned rover, the scope of human exploration on the moon can be greatly increased.] 】

[That's right, and you don't need to go up in real people, after all, it's too troublesome for real people to go up. 】

[Yes, in fact, the most ideal solution is for machines to replace humans to explore space, but humans need to go out in the end, so they still need to go to the human world. 】

[It's already a lot better, and when the astronauts go up in the future, just remotely control these vehicles in the lunar module, haha. 】

[That's right, let these remote-controlled vehicles explore a good place first, and if there is a need, the astronauts can go directly, and they don't have to come out and find it little by little. 】

[I really want to control the moon remotely...... it, it's overturned! 】

[, it's really overturned! ] 】

[Captain Tang's lunar rover overturned! ] 】

[Hahaha, what am I talking about, shame, wasting a lunar rover. 】

[That's it, what's the matter, the technology is not good, it's quite a wave, this is overturning.] 】

[Shame on the waste of scientific research assets!] 】

The surface of the moon is not the earth in the end, there is no flat road, and the rate of weathering cannot catch up with the earth.

The crater formed by a meteorite falling down can remain in its original state for a long time, and it will not be weathered by wind and rain and is slightly flattened.

In addition, it was a small slope before, and although the angle was not large, it just blocked the small pit.

The main thing is that there is also a slightly raised stone next to the pit.

If you drive alone on a small crater or rock, the roof will tilt a little at most, but this is not a big problem.

But now the two are combined, and the position distance is just right, and the wheels are just stepping on the lowest and highest points, then the inclination is larger.

Coupled with the fact that the previous small angle affected the detection efficiency, it was too late for him to see the real situation and the data warning.

As a result, the lunar rover went into the pit on one side, went uphill on the other, and overturned all at once.

Or the reason for the lack of experience, underestimate that kind of small slope.

In fact, the correct thing to do at that time was to slow down, allow enough time for reconnaissance and reaction, and confirm that everything was okay before passing.

But that's okay, it's all right.

The data shows that all the equipment is fine, it is operating normally, but the lunar rover simply fell.

If the general lunar rover is overturned, it is dangerous.

If you roll over, you can also try to use the rotation of the sun wings to lift the car.

But to be successful, the solar wing must be stiff enough, the motor must be strong enough, and the solar wing must be long enough.

If you can't satisfy all three aspects, then you're embarrassed, just lie quietly.

If it rolls over front and back, or even turns straight upside down, it's not to mention.

His remote-controlled lunar rover is not an ordinary carry, it is a two-dimensional vehicle, with a mechanical arm on it, and the motor power is definitely enough.

The moon has low gravity and the rover exhibits less weight.

Tang Chao manipulated the robotic arm and propped up the lunar rover little by little.

At this time, another remote-controlled car also came over, using the same robotic arm on the side, and turned Tang Chao's remote-controlled car very smoothly.

The command center cheered and applauded!

Terrific!

The achievement of the lunar rover successfully rescuing another lunar rover on the moon for the first time - achieved!

Not only did the rollover not cause an impact, but also completed a test by the way, which is cost-effective, no one.

And the barrage that was clamoring for Tang Chao to apologize just now disappeared in an instant, and it was all words of cheer and celebration.

At present, this experimental mission can be regarded as over, and it can be considered a complete success.

In an instant, the big screen in the command center turned into a big red screen.

[Warm congratulations on the success of the first flight of the Long March-9 carrier rocket and the Yuegong-2 test mission]
