Technology 451:How to Make Your Own Mechanical Hound
Tom Rebold, MPC Engineering Instructor
Technology 451
What role does Technology play in F451? What was Bradbury’s inspiration for the
Mechanical Hound? Has anyone created a Mechanical Hound? How can you build your own robots?
Sci-Fi vs Sci-Fact
A self perpetuating loop
Bradbury’s Mechanical Hound… The mechanical Hound slept but did not sleep, lived
but did not live in its gently humming, gently vibrating, softly illuminated kennel back in a dark corner of the fire house.
Light flickered on bits of ruby glass and on sensitive capillary hairs in the nylon-brushed nostrils of the creature that quivered gently, its eight legs spidered under it on rubber padded paws.
The Mechanical Hunter
“What does the Hound think about down there nights. Is it coming alive on us, really? It makes me cold.”
“It doesn’t think about anything we don’t want it to think.”
“That’s sad,” said Montag, “because all we put in it is hunting and finding and killing. What a shame if that’s all it can ever know.”
-- Fahrenheit 451, 1953

the first electric fire-control system
Norbert Weiner, 1894 – 1964Founder of Cybernetics
Cybernetics or the Control and Communication in the Animal and the Machine (1948). Norbert Wiener
Acclaimed one of the "seminal books . . . comparable in ultimate importance to . . . Galileo or Malthus or Rousseau or Mill", Cybernetics was judged by twenty-seven historians, economists, educators, and philosophers to be one of those books published during the "past four decades," which may have a substantial impact on public thought and action in the years ahead." -- Saturday Review
Cybernetics Is…
Math/Science of systems that have goals Using circular “feedback” loops of
sensingcomparing with goalsaction sensing …
Communication systems, control theory Applied to Animals, Machines, Business,
Government…anything that processes information

Is the Mechanical Hound a Cybernetic Hound?
Nights when things got dull, which was every night, the men slid down the brass poles, and set the ticking combinations of the olfactory system of the hound and let loose rats in the fire house areaway. Three seconds later the game was done, the rat caught half across the areaway, gripped in gentle paws while a four-inch hollow steel needle plunged down from the proboscis of the hound to inject massive jolts of morphine or procaine.
After the War…
Scientists/Engineers seek funding to apply wartime cybernetic techniques to broader problems
Ideas developed for military use describe: Living organisms Control and communication devices Human society
In terms of: Information, feedback, control
Other Developments in Robotics
1950Alan Turing publishes Computing Machinery and Intelligence in which he proposes a test to determine whether or not a machine has gained the power to think for itself. It becomes known as the "Turing Test".
1951The Day the Earth Stood Still premieres in theaters. The movie features an alien named Klaatu and his robot Gort.
Was this Bradbury’s Inspiration?
Gray Walter’s Tortoise (1948-1953)
Even organisms with extremely simple nervous systems could show complex and unexpected behavior
Steering motor on front wheel and driving on rear wheels
Two vacuum tubes for control
One photocell One bump sensor
Surviving Technology – the irresistible allure
Fahrenheit 451 as a critique of cybernetics Humans subject to “control” thru media No books = no independent thought
Mildred’s case: “It doesn’t think about anything we don’t want
it to think.” The ideal consumer—a mechanical human?
Clarisse: “I rarely watch the parlor walls,So I’ve lot’s of time for crazy thoughts.”
An unexpected bounty
As technology gets cheaper, the development of it gets more democratic
Technology as liberator
