Ron Plumb

Ron Plumb (born circa 1950s) is an American former child actor best known for his role as Robby the Robot in the television series Lost in Space. While his appearances as Robby the Robot were brief and often uncredited, his physical stature allowed him to fit inside the robot costume during scenes requiring movement and specific actions.

Beyond Lost in Space, information about Ron Plumb's acting career and subsequent life is scarce and largely undocumented in mainstream entertainment databases. His role as Robby the Robot remains his most prominent, albeit relatively anonymous, contribution to television history. He is sometimes confused with Danny Lockin, who also portrayed Robby the Robot, making definitive identification challenging.
