The gimpy genius known as Waldo lasts inside an orbital home ground & works earthside via remote manipulators he developed. It were described when getting the shape & manual dexterity of a man hand, so leaving the two to treat any man thing, including a second manipulator. It were available inside the kind of sizes, from either micro-manipulators to construction sized.

In the modern feel, the waldo occurs as remote manipulator. Modern waldoes will keep close at hand direct mechanical linkages or even exist when teleoperated as a originals in the story were. It could too exist as expanded to include all but any a share or even work of the person.
