On this day, Zhou Xin sat in the command cabin, his face was not very good, and in front of him was a report on the conclusion that the Voyager had just reached. Pen, fun, pavilion www. biquge。 info

After reading the report, Zhou Xin frowned and asked, "The damage to the engineering robot is more serious than expected?" Isn't the magnetic field the most important factor affecting the operation of the robot? Minerals harvested by engineering robots are causing more damage to them? Voyager, explain in detail. ”

"Since the engineering robots are not equipped with too many delicate parts, the impact of the magnetic field on these robots is much smaller than that of detectors." The Voyager began to explain, "However, there is another point that none of us have noticed before. It may also be because the probe did not collect resources on the planet, so this was not revealed until a few days after the engineering robot worked on the planet's surface. ”

"What is the reason?"

"The surface of the planet is covered with a strong magnetic field, which has been known since the beginning." Voyager continued, "But what the probe didn't notice under the strong magnetic field that spread across the globe is that most of the minerals on this planet are also faintly magnetic. ”

"Minerals?" Zhou Xin recalled the analysis report of the planet's soil sent back by the probe before, "You mean - magnets? ”

"Your guess is right." The next words of the Voyager confirmed Zhou Xin's conjecture, "The minerals of this planet contain a large amount of iron and nickel, and under the influence of the strong magnetic field of the planet, these minerals are more or less magnetic. This weak magnetism is not very obvious in lumpy minerals, but when the minerals are crushed by the machine, the dust raised will adhere to the metal objects under the action of magnetism, and at the same time, the dust raised by the robot moving on the surface of the planet will also have a weak magnetic effect, and these dust will also adhere to the metal objects-"

"Wait." Hearing the last words of the Voyager, Zhou Xin interrupted, "Why didn't the probe encounter this problem when it was moving on the surface of the planet before. ”

"The surface of the probes is diamagnetic, so the impact of magnetic dust on them is not as great as that of the planet's magnetic field. The batch of engineering robots on the surface of the planet was improvised on the dinosaur planet before, and the surface was not treated with antimagnetism, so a large amount of magnetic dust on the surface of the planet would adhere to the metal surface of the robot. After explaining, Voyager went on to describe the problems encountered by the robot, "These magnetic dusts adhere to the usual metal surface without problems, it is nothing more than a little increase in the load of the engineering robot, but if they adhere to the robot's mechanical joints or similar connectors, the impact cannot be ignored." A large amount of magnetic dust gathers here, which will greatly affect the flexibility of the robot, and also bring obvious wear and tear to these joints when the robot is active. Dismantling of these incapacitated robots revealed that their exposed joints had been directly blocked by magnetic dust, and some of the parts with severe friction had worn out more than a third. Other parts are also evident with varying degrees of wear, which can no longer be repaired and can only be replaced. ”

"And, not only engineering robots, but also those mineral mining equipment, mineral transportation equipment and mineral processing equipment have more or less this phenomenon, but compared with engineering robots, these equipment is less precise, so it is less affected, but with the continuous accumulation of dust, these equipment will have problems sooner or later, so the impact on these equipment cannot be ignored." The Voyager then added.

Zhou Xin frowned, "Is there a way to solve this problem?" For example—" he thought for a moment, "find a way to degauss the collected minerals first?" ”

"This ship has already launched a set of degaussing equipment to the planet base a few days ago." Voyager replied, "This does significantly slow down the wear and tear of the mineral processing equipment, but it is of no use to other equipment and robots. Degaussing devices are fixed equipment, and there is no way to equip every device and robot on this ship, so the speed of damage to parts will not slow down for them. Then it added, "And the energy consumption of the degaussing device itself is also very large, and if all the minerals are demagnetized, the energy on board this ship is not sufficient." ”

"You don't have to worry about energy." Zhou Xin waved his hand, "There is no shortage of energy in this galaxy, when the time comes, you can go to the two giant planets to collect them, Voyager, launch more degaussing equipment, what we need now is efficiency rather than energy saving." ”

"Understood."

Zhou Xin then asked: "According to what you say now, that is, except for the equipment in the temporary base, other equipment and robots that go out to mine cannot avoid the impact of magnetic dust?" So how big is this impact, and how much will the lifespan of engineering robots on the planet's surface be shortened? ”

"Yes, this ship has not yet found a solution to this problem, and any equipment that goes out can only be directly exposed to the magnetic dust on the surface of the planet." The Voyager came out with very bad news, "In this case, the lifespan of engineering robots is about ten to fifteen days, the lifespan of mining units is about five days, and the lifespan of transport equipment will be a little longer, around a month." ”

"The lifespan is too short." Zhou Xin's face was a little bad, "If it takes about ten days for engineering robots to be rotated, then we will stay here for even longer." He thought about it for a long time and realized that he couldn't come up with a good solution. Then he remembered Atlas, and with an attitude of trying, he called Atlas.

"Atlas, what are you doing, I'm looking for you." Zhou Xin shouted into the communicator.

"Is there anything wrong with the captain's brother? People are studying the reasons for the formation of these two planets. Before Zhou Xin's words fell, a familiar little girl appeared on the screen.

"After so many days of research, have you got any results?" Zhou Xin asked kindly.

"Although there are no concrete results yet, people already have eyebrows." Atlas's voice was a little excited, "Next, as long as the problem of how the two planets were together before is solved, then the reason for the formation of these two planets should be completely solved." Then she asked in an impatient tone, "So what's the matter with the captain's brother, let's solve it quickly so that I can continue to study these two planets, it's the first time I've seen such a magical planet." ”

Urged by Atlas, Zhou Xin felt a little embarrassed, but fortunately, Atlas couldn't see his expression now, and calmed down a little, and he briefly explained the issues he had just discussed with the Voyager to Atlas.

After listening to Zhou Xin's words, the little girl on the screen frowned cutely, "Brother Captain, are you going to let me come up with a solution to the problem of magnetic dust?" ”

"That's right." Zhou Xin nodded, and then looked at the little girl on the screen hopefully, "Do you have any solution?" ”

"Let me think about it." Atlas held his forehead, "I remember that those grandfathers also encountered such a problem in the earliest days, how did they solve it at that time, let me think about it, it's been a long time, and people have forgotten a little." ”

Originally, Zhou Xin had already planned to change the robot frequently in his heart, and he didn't expect Atlas to give any effective solution, but he didn't expect her to really have a solution, his mood was slightly excited, and then he stared at the little girl on the screen tightly. Although he knew that this had no effect on Atlas's thinking, he remained silent, for fear of interrupting her train of thought.

After a few seconds, Atlas clapped his hands and exclaimed excitedly, "I remember." ”

"What's the solution?" Zhou Xin couldn't wait to ask.

"Apply a special coating to the whole body of the robot, which will form a special protective film on the metal surface, and replace the protective film every day to alleviate the damage to the robot." Then, she said the disadvantages of this method, "But this is only a temporary solution, this protective layer is very thin, so a large amount of dust will still cause damage to the machine, and the wear and tear of the protective film needs to be replaced every day, very troublesome, brother captain, you still have to find a way to develop a diamagnetic material." If you really can't do it, they also have several formulas of diamagnetic materials here, but people don't know if you can make our materials with your technology. ”

"We also have diamagnetic materials, but we didn't expect to encounter magnetic dust on this planet." Zhou Xin smiled bitterly, and then he repeated the previous words of the Voyager to Atlas, and then he said helplessly, "So if you temporarily use diamagnetic materials to make machines now, not only will the materials be insufficient, but also a lot of time will be wasted, so let's use the method you said for the time being." Then he remembered a question, "By the way, is it difficult to make this paint you said, do you have a formula?" Let's see. ”

"It shouldn't be too difficult, it's all the materials that were commonly used on the earth in the past." Saying that, Atlas made a list of materials on the screen, and looking at the list of materials, Zhou Xin suddenly had a sense of familiarity.

"Isn't that the material needed for papermaking?" After a while, Zhou Xin finally recalled the items corresponding to this list of materials, "Atlas, did you send it by mistake, are you sure that these materials can make the kind of special paint you said?" ”

"Papermaking?" Hearing this word, the little girl was slightly stunned, and then showed a clear expression, "You mean the kind of material that can be easily torn up and can be used for recording?" Then she explained, "That's right, the same material is used for both things, but the grandfathers have improved the production process a little bit, and then it becomes this protective paint." ”

"I see." Zhou Xin nodded suddenly in realization, "Voyager, make some of this paint, and then give it a try to the engineering robots and machinery on the surface of the planet to see if it has any effect." ”

"Don't worry, it must have worked." Atlas played the package ticket, "except that it is a little more troublesome and slightly less effective." Those grandfathers used this method for a few years, and then the diamagnetic material was invented, and this method was abandoned. ”

"Okay." Zhou Xin nodded, "Then the Voyager, go make this paint." ”

Then Atlas asked urgently, "Brother Captain, are you okay?" It's okay, I'm going to continue studying those two planets. ”

"Go, go, go." Although he knew that Atlas couldn't see it, Zhou Xin still waved his hand at the screen, "Remember to tell me the results after the research is out." ”

"Got it—" Before Atlas could finish speaking, the little girl on the screen disappeared in an instant.

More than ten days passed, and on the day Atlas said how to make that paint, Voyager succeeded in making that paint, according to Voyager, the method of making that paint was not complicated, but it was just a few more steps added in the process of forming the pulp, and then the original pulp became a transparent liquid, and this transparent liquid was a protective paint.

The day after the paint was manufactured, Zhou Xin asked the Voyager to try out some of the robots on the planet's surface. It was found that the effect of this coating was still good, and although there were still some wear and tear at the joints of the engineering robot, it had been significantly improved. Seeing this situation, Zhou Xin breathed a sigh of relief, however, in the process of use, they also found new problems, in addition to Atlas mentioned that the paint must be replaced every day, the Voyager found that the engineering robot sprayed with this paint has decreased in flexibility, and it seems that the paint affects the activity of the joint of the engineering robot. However, this did not have a particularly big impact on the robot's activities, so Zhou Xin also allowed this paint to be used in large quantities in the future, and at the same time, according to the wear and tear of the robot in the next few days, the Voyager came to a relatively acceptable conclusion - under this level of wear, the life of the robot can reach about a month, which is not much different from the life of the robot's core on the planet.

Hearing this conclusion of the Voyager, Zhou Xin finally completely relieved, and he instructed the Voyager to repair the spacecraft while building a backup engineering robot in the temporary base. Finally, Voyager was able to get a complete repair on this not-so-satisfactory planet......
