Gregory's Server@skobkin im not so sure of that.. i mean wire isnt that expensive, and those robots need to communicate nad have processing power... id imagine the coils would be cheaper, at the very least affordable.. just taling about some chunks of iron and a bunch of wire.

 @skobkin yea this is one of those things we would have to test.. im not even sure how much power youd really need.  @freemo But... Moving pieces are still fun! @skobkin usually electromagnets using thin wire wth many turns @freemo Yeah, it's more efficient, but minimally sufficient thickness of the wire is still a thing to determine. Also a subject for modeling and calculation... All this sounds like a very interesting engineering project. @skobkin very doable without much advanced EE... but still a tehcnical challenge. Sure, would be fun. @freemo @skobkin being done with a small ball: https://incoherency.co.uk/blog/stories/electromagnet-grid.html @freemo |

We still need at least the same amount of computations if not more when working with coils. Especially if trying to achieve smooth movements. We also need something to manage high currents on such a large scale. Let's say, we won't be considering fully paralleled operation of all coils at the same time. But we still need to be able to power at least ~8 coils at the same time.
Main challenge from my PoV is potential magnetic interference which can reduce the efficiency of each coil. But it's a task for some physics modeling, not just sudden brainstorm in Mastodon comments.
