Re-used several diving sequences from "The Monsters Web"
In 1932, Paul Fix played a woman in The Little Rascals short "Free Eats".
This episode takes place in the 1980s.
The robot used was actually a "Martian Astronaut" from the early 1960's. The chest doors are covered with cheap cardboard and very unprofessional detail paint on the outside. You can see the edge of the cardboard applied to the chest doors when they open. On the back of the doors, you can also see the cutouts for chest windows that would've emitted a neon glow. The top was replaced with a Knights helmet and the whole thing was painted silver.
