Two versions of the robot were used during Lost in Space filming a "hero robot" costume worn by Bob May, and a static, "stunt robot" prop that was used for distant or hazardous shots. Both versions fell into disrepair after the series, but these have since been discovered and restored. The "hero" was privately owned by TV and film producer Kevin Burns, who commissioned a replica in the early 1990s for touring and conventions. The "stunt robot" was on display at the Science Fiction Museum and Hall of Fame in Seattle, Washington from 2004 until it was offered at auction by Heritage Auctions in 2023.

Like Robby the Robot, the Robot prop costume was re-used on at least one other show. On the Saturday morning children's show Mystery Island, it was modified to make the primary character "P.O.P.S." There it had different domes, different color scheme, and an added rectangular skirt of gold colored tubes, covering the rubber bellows legs and base.
