IMDB

Frankie Avalon is a secret agent.  He meets a hot chica, who turns out to be a gold digging robot created by Dr. Goldfoot.  Dr. Goldfoot is using an army of sexy robot women to con rich men out of their fortunes.  Frankie hooks up with Dwayne Hickman, who is one of the targets of Goldfoot.  They aim to take Dr. Goldfoot down.
I loved this movie.  It is completely insane.  It is pure camp.  Vincent Price, who plays Dr. Goldfoot, is hilarious.  Frankie Avalon and Dwayne Hickman are great and have some great moments of slapstick.  Of course, there are plenty of sexy mod women.  And there is the greatest chase scene in film history.  The chase sees a constant change of vehicles.  It's hilarious, crazy and amazing.
This is currently on Netflix Instant Watch.  If you happen to read this--and very few will happen upon it, surely--watch it.
By the way, a bikini machine refers to the female robots.  There is not a machine that mass produces bikinis.
