While ice is a somewhat extreme example, the idea of bringing over the electronics and using local materials to put together whatever structural components are needed isn't that crazy. It'd save a lot of mass, and things like 3d printers can produce them with reasonable precision. There already is a decent amount of research into the prospect of 3d printing structures with Lunar or Martian regolith, so structural components for robots or machines don't seem too crazy.
