Can you imagine why a robot would need to yodel? I’ve got no idea because yodeling is fricking annoying in my book. Radio Man was featured in the April 1939 issue of Popular Science, and was the Slim Whitman of early android technology.
When I talk about retro tech, I’m usually going on about stuff from the late 1970s or early 1980s since those were the years that really defined me as the geek that I am today. The 1930s, on the other hand, are just a wee bit before my time.
