The engineering term "waldo" for a remote manipulator was coined in Robert Heinlein's 1942 story and adopted by real teleoperator builders

"Waldo" entered engineering vocabulary as the name of a remote manipulator through Robert A. Heinlein's 1942 science-fiction story Waldo, whose disabled protagonist controls mechanical hands at a distance. Per Wikipedia, "in reference to this story, the real-life remote manipulators that were later developed also came to be called waldos, some even by NASA." The coinage is a case of fiction naming a technology before the technology was widespread: the word attached to actual hardware and persisted into official usage, even as later users forgot its pulp origin.

The capture recorded a fuller lineage — that Raymond Goertz built the first practical master–slave manipulator at Argonne National Laboratory in the late 1940s to handle radioactive material behind shielding, and that the animatronics firm The Character Shop later trademarked "Waldo" for puppetry control devices. Those historical details were drawn from cyberneticzoo.com but were not quote-fetched at capture, so they are carried here as [unverified-mechanism/quant] and routed to question-verify-waldo-teleoperator-lineage-goertz-character-shop; only the Heinlein-to-generic-term etymology rests on a directly read (if Tier-4) quote.

As an uncontested etymological/definitional claim, the core statement clears the Tier 3–4 sourcing floor; the surprising, load-bearing historical specifics do not, hence the seedling status. The term is the connective tissue for the entertainment-technology thread in claim-henson-1988-waldo-realtime-cg-puppet-control, which named its 1988 device after this decades-older engineering word.
