Yeah, everything that Mal said.
And also...

Hmm.
I don't like the idea of making nanobots out of plastic and motors and
whatnot, because that's not how they work, to my knowledge; they're made
out of carbon and move by manipulating their electromagnetic fields to
cause their molecular structure to flex. He might have built microbots
that way, though, as a way of scaling up assembly from what the nanobots
assemble on the molecular level.

Uh, dude...  That may not be how things work in reality, but Handwavium likes to slap physics to the ground while yelling, "Bitch!  This is how -I- roll!"  It can definitely make some Mind Storms machines into nanobots, especially if it was accidentally done.
