A remote manipulator, also known as a telefactor, telemanipulator, or waldo (after the 1942 short story "Waldo" by Robert A. Heinlein which features a man who invents and uses such devices),[http://www.technovelgy.com/ct/content.asp?Bnum=23 Technovelgy telemanipulator page] is a device which, through electronic, hydraulic, or mechanical linkages, allows a hand-like mechanism to be controlled by a human operator. The purpose of such a device is usually to move or manipulate hazardous materials for reasons of safety, similar to the operation and play of a claw crane game.
History

In 1945, the company Central Research Laboratories[http://www.destaco.com/crl-products-equipment.html CRL history] was given the contract to develop a remote manipulator for the Argonne National Laboratory. The intent was to replace devices which manipulated highly radioactive materials from above a sealed chamber or hot cell, with a mechanism which operated through the side wall of the chamber, allowing a researcher to stand normally while working.
The result was the Master-Slave Manipulator Mk. 8, or MSM-8, which became the iconic remote manipulator[http://www.destaco.com/telemanipulators.html Telemanipulator page] seen in newsreels and movies, such as The Andromeda Strain or THX 1138.
Robert A. Heinlein claimed a much earlier origin for remote manipulators.{{citation |last=Heinlein |first=Robert A. |author-link=Robert A. Heinlein |chapter=Science fiction: its nature, faults and virtues |editor-last=Davenport |editor-first=Basil |title=The Science Fiction Novel |publisher=Advent |location=Chicago |year=1957 |publication-date=1959}} He wrote that he got the idea for "waldos" after reading a 1918 article in Popular Mechanics about "a poor fellow afflicted with myasthenia gravis ... [who] devised complicated lever arrangements to enable him to use what little strength he had."
