"I started writing in the 1930's when I was eighteen years old. And deep inside me I'm still eighteen and it's still 1938."
- Isaac Asimov

| Waldo | ||
| A telefactoring device; also known as the Waldo F. Jones Synchronous Reduplicating Pantograph. |
This story has been largely forgotten (even though it still makes great reading). The notion of a waldo, however, has not. The word itself has come into common usage; the American Heritage Dictionary describes it as follows: "A mechanical agent, such as a gripper arm, controlled by a human limb." Real-life waldoes were developed for the nuclear industry during WWII; they were named after the invention described by Heinlein.
This technology is known today by the more generic term "telefactoring"; it is used in a variety of industries.
In the story, Waldo is in orbit around the Earth, in his space station called "Wheelchair"; he controls waldoes far below, on Earth.
| Near the man, mounted on the usual stand, were a pair of primary waldoes, elbow-length and human digited. They were floating on the line, in parallel with a similar pair physically in front of Waldo. The secondary waldoes, whose actions could be controlled by Waldo himself by means of his primaries, were mounted in front of the power tool in the position of the operator.
‘Very well, friend Alec - the gloves.’ Jenkins thrust his arms into the waldoes and waited. Waldo put his arms into the primary pair before him; all three pairs, including the secondary pair mounted before the machine, came to life. Jenkins bit his lip, as if he found unpleasant the sensation of having his fingers manipulated by the gauntlets he wore.
 (Waldoes worn by Waldo from 'Waldo' by Robert Heinlein) Waldo flexed and extended his fingers gently; the two pairs of waldoes in the screen followed in exact, simultaneous parallelism. “Feel it, my dear Alec,” Waldo advised. "Gently, gently—the sensitive touch. Make your muscles work for you." He then started hand movements of definite pattern; the waldoes at the power tool reached up, switched on the power, and began gently, gracefully, to continue the machining of the casting. A mechanical hand reached down, adjusted a vernier, while the other increased the flow of oil cooling the cutting edge. “Rhythm. Alec, rhythm. No jerkiness, no unnecessary movement. Try to get in time with me." |

Heinlein shows his creativity by giving his character a problem (myasthenia gravis - degenerative muscle weakness) and then literally giving him the tool to solve it. You'll also enjoy his laboratory (in orbit, of course, to give Waldo maximum mobility).
A pantograph is a device with a simple physical connection between a pointer and a drawing pen on a piece of paper. Altering the linkage between the pointer and the pen alters the scale of the drawing. The pantograph dates from 1630. Thomas Jefferson liked them; he built one into Monticello.
In Oath of Fealty, by Larry Niven and Jerry Pournelle, telefactor operators who all live in the same arcology assist in a variety of tasks around the globe (and on the moon). At one point, they go on strike; a case of acting locally and globally.
Compare to microhands from Microhands (Микроруки) (1931) by Boris Zhitkov and the iron fingers from The Death's Head Meteor (1931) by Neil R. Jones.
