Ask any roboticist of a certain age, whether a professional or hobbyist, how they first got interested in robots. Odds are good they'll mention a 1976 TAB book, written by David L. Heiserman, called Build Your Own Working Robot. The book described the construction of Buster, a small, wheeled robot. This was before the era of ubiquitous microprocessors. Buster's brain was a mass of TTL logic chips that implemented surprisingly complex behaviours. In some ways, Buster was not unlike Grey Walter's vacuum tube-based turtle robots from the late 1940s and was likely the first significant step forward in behavior-based robots since Walter's turtles. Did you ever wonder what Dave did after writing those books or what he's up to today? Read on to find out!
