Chapter 42: Disappearing Villagers' Houses
"If only the special transport vehicle was still there."
Su Wu was in a dilemma.
Although the previous storm did not significantly change the course of the river, it did cause considerable damage to the terrain. With the small toy-like bodies of the mini excavators and mini transporters in the current engineering team, it is bound to be a very difficult task to navigate in such a complex environment. If you are not careful, you will overturn.
But no matter how difficult it is, we have to do it. The construction of the shelter cannot be stagnant for this reason.
After being troubled for a while, Su Wu quickly thought of a solution.
That is to install a detection radar on the micro excavator.
At present, the machinery in the engineering team basically uses cameras to identify the external environment. This method of relying solely on image recognition is too simple and cannot detect various hidden traps. If it can be equipped with a detection radar, it can make up for this defect to a great extent.
As long as the trap can be discovered in advance, with the ability of the mini excavator, there are many solutions to choose from, whether it is filling it on the spot or taking a detour. There will basically be no rollover or getting trapped.
However, actually installing the detection radar is not an easy task.
Radar is not cheap, and truly high-performance industrial and military-grade radars are not something Su Wu can afford.
The batch of supplies previously purchased from the official shelter included only ten of the cheapest commercial-grade lidars and sonic radars.
The effective detection range of laser radar is 25 meters, and it can only identify unobstructed pits. Its accuracy is only slightly better than that of camera recognition. Sonic radar can further detect those hidden pits, or simply determine whether the ground is solid enough to support the vehicle. However, its detection range is only 3.5 meters, and there are a lot of blind spots. Each detection can only detect a fan-shaped area within 60 degrees in front.
At the same time, they also have various problems such as the working environment temperature cannot exceed 50 degrees, the detection head is precise and fragile, etc.
Su Wu studied for more than ten minutes before he came up with a final solution with the help of artificial intelligence and the database.
Both types of radars are installed and equipped with a waterproof and dustproof casing, a freely rotating base, and a separate cooling system.
This solution cannot be said to be very good, but at least it can make the radar operate normally.
If we ignore the difference in accuracy, reaction speed, and detection distance, there is not much difference between it and the terrain radars on large trucks and special transport vehicles upgraded with survival points. It can already be used in practice.
More than two hours later.
The construction robots that successfully completed the first phase of the construction task began to return to the shelter one after another.
They cleaned the dust and dirt on their bodies in the disinfection room on the first underground floor of the shelter, and then went to the manufacturing center on the second underground floor to receive routine maintenance from the engineering robots. Finally, they split into two, two of them received rifles and magazines at the manufacturing center and guarded near the shelter's lifting platform. The other six joined the engineering team and went to the fourth underground floor to participate in excavation and expansion of the shelter.
And at the same time.
A mini excavator and a mini transporter separated from the original construction team and came to the ground one after another. Then they turned on the lights in front of the cars and slowly drove towards the land in the distance that was swallowed by endless darkness.
"I hope nothing happens."
Su Wu looked at the small convoy gradually disappearing into the darkness through the ground surveillance of the shelter, and a vague worry grew in his heart. It felt as if this was the last time he would see them.
I was in a daze for a while.
Su Wu began to switch the main control screen to the mini excavator that was leading the way away.
The lines of data that were refreshed on the screen indicated that the status was normal, and the old road signs that could be vaguely seen under the light of the car lights made Su Wu feel a little less uneasy. The storm not long ago was not all bad. At least it almost cleared the ground from the global forest fires and the ashes brought by the volcanic eruption.
Judging from the environment near the highway, it looked like a remote suburb that had suffered a drought. It was not like an alien planet. The whole world was covered with a gray hue, and it looked like a silent hell that made people feel depressed and desperate.
Due to its size, and the fact that there is a lot of gravel and debris on the road that has not been cleaned up.
The speed of the micro excavator and micro transporter is not very fast, only less than 10 kilometers per hour.
Su Wu waited for nearly 15 minutes before he saw them leave the road and turn into a country road on the side where there was almost no trace of them.
This is the route closest to the river.
In the past, there were two or three self-built houses and a piece of abandoned farmland here, but now they are completely gone.
"It should be right in the center of the storm belt."
“It was completely destroyed.”
Su Wu controlled the camera on the mini excavator and turned it to the location of a self-built house.
At this time, the place had become a sunken earth pit. In the earth pit, except for a pile of rubble carried by the storm, there was no trace of any man-made buildings.
He remembered that a family of five once lived in that house. The head of the family was a middle-aged man named Miao Yijun, who had a very cheerful personality.
When Su Wu first came here, he asked him to help buy some gasoline and sugar. At the same time, he also heard him brag about his own vegetable cellar, which was spacious and sturdy, and could be used as a shelter without any problem.
However, while the words were still ringing in his ears, his house and his sturdy vegetable cellar had disappeared forever in the storm.
"Hopefully they have all been moved to official shelters ahead of time."
Su Wu sighed silently.
I didn't insist on getting closer to find out the truth of the matter.
Get off the road.
The leading mini excavator moved even slower. Occasionally, it encountered some rocks and pits blocking the road, which it had to dig through or simply take a detour. After all this trouble, by the time it reached the edge of the river, nearly half an hour had passed.
At this time, warnings came again from the large trucks and special transport vehicles that arrived at the edge of the city to clear the roads.
The wind over there began to gradually get stronger.
The reconnaissance drone formation on high-altitude alert had been forced to land in the cab of a large truck and could no longer perform its normal alert mission.
"Is this another storm coming?"
Su Wu was subconsciously startled. But he looked through the official forum and did not find any similar disaster warnings.
