Actually we have something like that even now though it is bigger. I don't know the details but the ball shape moves by shifting it's weight inside. These also seem to be at least magnetic.
Can't find anything like you've mentioned (not enough context), but after thinking about it for some time I could see a way to move the spheres by some kind of internal motor that clamps down onto the ground touching portion and moves it (like a hamster in a ball...), but it would only ever be able to rotate it in one axis at a time, thus steering essentially like a tank.

The problem here is that such propulsion would be very weak and I doubte it would be able to climb walls.

I want to get hyped with the anime but it's LN anime, man...

why? isn't the novel better than the manga version? I read some of the officially translated novel and the manga just seems like a stripped down to knickers version of the novel.

yo mods. Don't ban for this, I made a small joke using material referenced from the current chapter that this forum thread is based on. I'm not spoiling anything unless if someone has chronic amnesia.

I did a quick google of "ball shaped robot" and it actually gave a me a few examples. Seems Samsung is even selling one as a Toy. I also looked a little further and the Wiki page for "Spherical robot" gives a nice explanation for how they work.
And as I mentioned considering the shape he carried them in they are probably magnetic of have some other anti Grav tech build in. Let's be honest though, this manga has "casual space flight" as it's main trope. It was never really "hard" on the Sci fi Scale to begin with.

The ones I found are supposed to be of Chinese make and like anything from China, the actual functionality is always highly suspect of being heavily overstated. In any case, I found an actual paper on the design of such machines and to my surprise, the idea I mentioned turns out to be pretty much the most robust currently known but rarely used due to the cost. The most common way to move them involves displacing their center of mass, but this is less moving and more gently rolling, they have trouble overcoming even small bumps on the surface.

The problem with assuming "they are magnetic" is that it wouldn't work. The center of mass displacers certainly wouldn't be able to move even an inch vertically, and the motor powered one would likely not be able to overcome gravity and friction without wearing out both the sphere and the motor. So yeah, it requires fantasy tech as you;ve guessed.

Technically Samsung is Korean. It is by any means a toy due to our limited tech. I assume these in story ones use some gravity gimmick. Gravity Control has been well established as a thing in the Story as both Ships and Stations have Gravity and artificial gravity was at least mentioned once early. As for why I mentioned magnetism there is actually a lot of musing about all the wonderful bullshite we could do if we could properly control magnetic fields but it was mostly because the "form" he carried them in is actually a neocube, classic cube design made of Magnetic balls ... except these are gravity defying spy bots instead.

What do you mean? We're pretty good at that. The only real "holy grail" that comes to mind on this topic are magnetic monopoles, which probably can not exist.

What's sorry is your low iq take, maybe if you had reading comprehension you'd understand I never wrote that animation isnt important but that flow of the story is simply more important, at least for people who value storytelling that is, but your low iq took parts of the comment as extreme and built some dumbass argument on false equivalence. Not gonna bother with your low iq takes anymore, either reading diagonally or just lacking reading comprehension as a whole, not worth my time.
As someone that actually worked in theater and stage directing... I can tell you that you are wrong. They are equally important, which is what I said in the first place. It's not low IQ, it's just hard facts. If it looks like ass, people are going to lose interest, if the story is shit, people are going to lose interest, if the pacing is bad... guess what.. people are going to lose interest.

All of it needs to come together. They are all important. One isn't greater than the other. If you focus on one over the other, the whole things suffers as a result.

YOU as a person might be able to look past certain elements that are lacking, but that does not mean that anything I've said is wrong or "low IQ". You're the one that seemingly can't accept millennia of collective knowledge on the subject.

Properly might have been the wrong word, not a native English speaker. I did not mean Monopoles (since as you said those might be impossible, though a favorite of soft sci fi). I meant more "Sci fi" level of Magnetic Field control you can sometimes see in shows or books (and people at least claim it is theoretically possible, granted they claim a lot of things). Not sure how put it properly in English.
...actually thinking about it considering he carried them in a Neocube the ball bots might produce Monopole Magnets instead of gravity stuff. The Science is soft enough in this manga for that.

Can't say much without knowing which shows or books you have in mind, though I have seen media which invented "futuristic" devices that were pretty much born from a lack of understanding of the physics of electromagnetism. Things like a single electromagnet creating a field of some weird shape (and bounded to a specific room no less) and the like.

Honestly main issue is over the decades I watched hundreds of Movies and read hundreds of books so remembering a specific name is difficult. But yeah your example is more a classic "Soft" Sci fi one.
