It’s hard in two senses: one, it’s hard to translate low-level commanding into meaningful work in all but the most controlled of environments. That’s why robots that are economically viable today are nearly all on factory floors: that’s basically the only setting where you can control the environment well enough for them to be useful. And two, for “advanced” robots (quadrupeds/humanoids) it’s very hard to get them to even balance, much less walk. Yes, there are robots that do this today — surprisingly well, in fact. But there is a tremendous amount going on algorithmically under the hood to make it happen. Figuring out how to make them work took decades of research in controls. This is largely a restatement of what you said above, so I suppose it depends on what you mean by “low level”. My intent above was low level in horse terms, which includes standing and walking. Things humans think of as atomic behaviors.
