More than half a century ago, Robert Heinlein created a science fiction short story that centered around the concept of remote manipulators that he called "Waldos". By an odd coincidence, the protagonist in Heinlein's story. Waldo Farthinwaite-Jones, was severely handicapped and invented the robotic assistance devices to help cope with his own personal disability.
The story was first published in the August 1942 issue of Astounding Magazine. Finally, after 60 years of research, development, trial and error, and uncounted millions in investment, we're finally getting reasonably close to having practical robotic devices that start to fulfill Heinlein's vision.
