    The Westinghouse Electric & Manufacturing Company, founded in 1886, was a pioneer in the development of communications technology. In 1927, Westinghouse engineers developed the Televox, a telephone-operated industrial switching machine. Using three tones carried over telephone wire, the Televox could regulate the flow of gas, water or electricity in factories or utility plants by instructing electrical relays to open or close in specific sequences. Before this time, a human switch operator had to be present at each step.This 1929 photo, possibly taken in Seattle, shows a man standing by a demonstration model of the Westinghouse Televox. The actual machinery is in the chest of the robot. In addition to operating electrical relay switches, this "mechanical man" could also move its arms and lift a telephone receiver. less
