I think the Telepresence Hand controlled by a Raspberry Pi is a great hack, but
there's another name for it, and science fiction writer Robert A. Heinline coined it nearly 80 years ago. He called it a Waldo, named after a fictional character, Waldo Farthingwaite-Jones. You can read about it in a story by the same name, first published in Astounding magazine in 1942, and reprinted in a book in 1950 that contains another story that is also fantasy. The name of the book is Waldo & Magic Inc.

As a tribute to Heinlein, remotely operated mechanical hands (not this sophisticated) that were used to handle dangerous materials used to be called Waldoes.
