The book “Robots of Westinghouse” has a lot of information on Elektro and several predecessor robots Westinghouse built. The book is uneven and needed an editor, but the technical content is fascinating. Elektro was built largely with components (motors, relays, wiring) taken from Westinghouse appliances. There is a picture showing a bundle of cables like those used on kitchen appliances, with braided cloth cords and Bakelite plugs at the end. My mother’s electric skillet had one of those power cords.
