There is Fischertechnik, a German brand. Don't know how common it is outside Germany. It's pretty close to "real" robotics/construction.

I'm aware of it... and its one of the "when I get my desk lego things done, I'll get one of them to play with" - https://www.fischertechnik.de/en/products/simulating/trainin... has been particularly tempting.

The factory must grow into real space.
