1. we were able to make a small skeleton, but the joints were not satisfactory. The movement is not good, and there is a lot of rattling.
If you want to do precision work, it will not work if there is any rattling here.
The output of the magical muscles is not balanced.
This is the reason why the movement is not smooth.
These were the two points.
"I see."
Jin nodded.
"First of all, the joints are probably not precise enough.
< have the disadvantage that they are not simple spherical joints and are difficult to reshape.
Usually, this becomes less of a disadvantage with skill, but in the case of the <, it seems that they were not yet at that stage.
The error in processing by < is constant regardless of the size of the workpiece.
Therefore, errors that were not a problem when machining large workpieces can no longer be ignored when machining small workpieces.
Incidentally, while Jin is able to track down errors to the nearest tenth of a micron, ordinary engineers can only do so to the nearest millimeter, or at best, to the nearest 0.1 millimeter.
One millimeter to a meter is negligible, but one millimeter to 10 millimeters is too large an error.
"And the output of a muscle is proportional to its cross-sectional area. So if the size is reduced by a factor of 4, the weight is reduced by a factor of 64 and the power output is reduced by a factor of 16. We just need to balance this. We just need to achieve this balance.
"I see. ......"
Jin's explanation seemed to make some sense to everyone.
"If it's too difficult, I think it's okay to use spherical joints instead of < only for the joints.
Jin said, "Because the purpose of the aircraft is to be used for in the first place.
"If those are the prerequisites, <> should be fine."
Jin also said that since the machine is designed to be piloted by humans, the reaction speed does not need to be very fast.
"It is also necessary to design a machine that is suitable for its intended use.
Rasnath Heilbronn, the head of the <>, seemed to realize what he had just said.
"No, Mr. Jin, you are right. This small golem was commissioned by the Aeronautics Research Institute. We had to consider it separately from the subject of our research, didn't we?
Rasnat scratched his head, "It was a mistake not to put as much emphasis on orders as we did in the general workshop, since we are a laboratory.
"We will continue our research on making small golems, but we must complete the requested golem for the on time."
Rasnath Heilbronn notifies the members of the .
"I'm sure you've all heard about my talk with Mister Jin. Let's use our form drives and get this done in time!
Yes, sir!
"Yes, sir!" "Yes, sir!"
So began the production of a small golem using <>.
(<> is suitable for a small golem. ...... It's an unexpected discovery.
Reiko tugged on Jin's sleeve while he was thinking about this.
"Father, it's time ...... to go."
"Oh, I see."
It was almost dinner time.
Dinner was about to be served, so Hitoshi said,
"I'll come back tomorrow.
He said no, and left the room.
As he was leaving, Eira said
"Thanks for the advice, Jin. Look forward to seeing you tomorrow!
After dinner in a private room, Jin told Erza about his time at the .
"It's true that the <> is suitable for small golems.
Erza agreed with Jin's opinion.
"I think it has a good balance of weight and power. It doesn't have any rattles.
Jin also thinks about the reason over a cup of tea.
"Maybe, yes. < is its slow speed, but I think the cause is inertia.
"Indeed. That's why it would be beneficial to use it on a golem with a small mass, in other words, a small size."
Jin thought that perhaps the smaller the golem is, the more advantageous the <> would be.
"It's a real game changer," he said.
"And it's not too hard on the joints."
"No need to make a separate exterior. And there's no need to build a separate exterior.
The more I think about it, the more I realize that it is suitable for a small golem.
"Well, I guess we can count on that tomorrow."
"Yes."
Jin and Erza nodded at each other.
"So, are we ready for tomorrow's lecture?"
"Yes, I have already decided on the content.
Elsa said that today's lecture would be an overview of the structure of the human body, and tomorrow's lecture would focus on internal organs.
"I might go to in the morning and in the afternoon. I'm sorry if I can't come to your lecture.
"Nah, I'll be fine."
Elsa smiled and said to Jin.
"My brother Jin and I are here to show the way to those who will come after us.

That night, the two of them spend the night relaxing.
Although a hot spring is not available on this man-made island, the bathtub in the guest room is large enough for one person to stretch out their arms and legs and soak in the hot water.
Since Elsa had taken the bath first the day before, Jin used the bathtub first on this day.
Reiko did not enter the bathtub because it was for one person, and she and the old man were discussing something on the built-in manacam.
Jin noticed this after he left the bath,
"Reiko, you were talking with the old man about something.
Reiko said.
"No, father. I know it's a bit much, but we were discussing whether it would be better to collect data on the effectiveness of the form drive I mentioned earlier for small golems.
"I see, that may be true. Thank you, Reiko.
The earlier we start such data collection, the more data we can collect.
Reiko and Lao-kun thought that Jin would want to try to make his own products as soon as he returned to Horai Island, so they decided to make preparations for that.
Jin was pleased and proud of their initiative.
* * * * * * * * * * * * * * *
"Well, that's a good idea!
"Oh, I didn't know there was such a way.
And at the , small golems using were being made at a rate that would keep them up all night. .......
