Contrary to the perception of ordinary people, Calmede is not actually dark. At least not on the side facing Jupiter.

Although it is more than 700 million kilometers away from the sun, the sun as seen from here is still very bright, even brighter than the full moon seen on Earth, enough to illuminate the shadows of objects. Especially since the wreckage planet impact event has just occurred, its brightness is even higher.

At the same time, Jupiter is also bright enough to shadow objects on Callisto because of its proximity.

In this way, the objects on Europa have two shadows. Combined, the Sun and Jupiter provide light that can give Callisto a similar lighting environment to the twilight on Earth when the weather is not so good.

In addition to Jupiter and the Sun, the two brightest objects, there are four extremely bright stars in the sky. Chen Yue knew that they were Europa to Io, four large satellites.

In addition, there is a band of light in the sky, which is extremely gorgeous, and it crosses the entire sky. As Ganymede orbits Jupiter, this band of light is sometimes wide, sometimes narrow, and sometimes disappears completely.

That's Jupiter's rings.

It's away from the sun, away from home. But it's also a bizarre and colorful world.

After enjoying the scenery here for a while, Chen Yue did not rest - anyway, he would not be tired at this moment, and directly started the follow-up work.

During his years of voyage to Jupiter's system, Chen Yue has been thinking about the question of how to proceed on his path to the rejuvenation of civilization.

There are many, many things to do, and there has to be a priority.

The final result of thinking is that the most important thing is to comprehensively judge the current situation and situation, and build a few robots first. All other goals and tasks can be postponed.

You must know that at this moment, the only thing that Chen Yue can manipulate and can move freely is Xiaobai, a robot. Without Xiaobai, or Xiaobai has some malfunction, or accidentally damaged, Chen Yue will have to be paralyzed again.

As for how to make robots, Chen Yue is not worried.

The central computer of the original Glowing spacecraft contained an extremely large database of almost all categories of knowledge from the Steam Age to the Electric Age.

Of course, there is no knowledge that is too cutting-edge, cutting-edge, and specialized.

The main reason for setting up this database is that it is too inconvenient for Mars to communicate with Earth. Once some accident encounters and the two lose contact with each other, the astronauts on the Glowing spacecraft or Mars can find a solution to the problem by looking for a solution.

Now, this database has become Chen Yue's most valuable asset.

After the integration with the computer, this knowledge has truly become Chen Yue's own. He can not only memorize this knowledge firmly, but also understand and master this knowledge in an instant with his huge computing power, and he can also learn and apply it lively.

It is in this situation that Chen Yue developed the manufacturing method of the robot by himself through simulation based on the working principle of the robot, the robot maintenance manual, the circuit table data, etc.

There are manufacturing methods, and there is no shortage of materials.

The "ransacking" of the Mars base at the beginning gave Chen Yue a large number of spare parts. In the past, during interstellar voyages, there was no gravity in the Glowing spacecraft and it could not be manufactured. Now that it's landed, there's gravity — even if it's small on Callisto, but as long as it's there — and manufacturing is certainly on the agenda.

So, with Xiaobai as his hand and intelligent machine tools, 3D printers and other equipment as the manufacturing platform, Chen Yue spent three days and finally built a new robot.

The robot is about one meter five tall and has four arms and four wheels. The four wheels can also be expanded into four legs, so that it has more passability.

The positioning of this new robot is a maintenance robot. With the dexterous robotic arms on it, it can repair almost anything, even itself.

"Make sure you don't get paralyzed before you can think about development."

Looking at the No. 2 robot that was slightly rough and even had exposed cables, Chen Yue was very satisfied.

After completing the manufacture of the No. 2 robot, Chen Yue continued to build No. 3 to No. 10, a total of eight new robots. As a result, Chen Yue's troops instantly skyrocketed tenfold, and there were a total of ten robots that could be driven.

After completing these nine robots, Chen Yue refused to rebuild them.

Because these nine robots are all assembled from the parts carried by the Glowing spacecraft itself. The number of parts that come with it is limited.

"In the future, these components will only be used in critical locations. The rest of the less important parts should be produced by themselves. ”

It's not okay to sit and eat empty. You have to have the ability to make your own blood.

So in the next step, Chen Yue sent No. 1 Xiaobai and No. 4 to No. 10 robots out to prepare to start working. Robots 2 and 3 were left inside the ship to prevent an accident that could cause the robots to be wiped out.

A total of eight robots traveled to eight different locations to begin further field exploration of several pre-identified mining areas.

The results of the exploration made Chen Yue quite satisfied.

It was here that he found almost all the mineral deposits he needed. Although some rare metals have not been found, the Glowing spacecraft can still hold on to the fuselage reserve for a while.

The mineral collections found on Callisto are not good, and the reserves are not much, but if they do, Chen Yue really doesn't dare to expect too much.

After confirming the location, grade and type of the deposit, Chen Yue quickly formulated a mining plan.

Intelligent refining robots are undoubtedly at the heart of the whole plan. By adjusting different parameters, it can process and refine dozens of metal minerals, and of course, don't expect it to be fast.

But it doesn't matter, Chen Yue can afford to wait.

As a result, the eight robots turned into hard-working workers, and after manually mining ore, they were directly transported to the intelligent smelting robot, which processed and refined, and finally produced an alloy that met the requirements. The metal is then transported to a smart machine for further processing and final into parts.

Limited by performance, the quality of the parts produced by this process is generally not up to standard, and the performance is not up to standard. But Chen Yue didn't care at all.

It's all this time, as long as you have to use it, what else can you hope for?

But smart machines also have limitations. Some parts that are too delicate to be produced at all.

At this point, it's time for 3D printers to come out.
