who played the robot on lost in space

The robot on the original Lost in Space (1965-1968) wasn’t played by a single person, but rather it was a prop costume operated by a performer. Here’s a breakdown:

• Prop Costume: The robot suit was a complex and cumbersome costume built by Bob Stewart.
• Performer: Actor Bob May wore the robot suit and brought the character to life through his physical movements.
• Silent Performance: Due to the limitations of the costume and the filming techniques of the era, the robot character was silent. Its communication was limited to body language and flashing lights.

While Bob May didn’t provide the voice of the robot (the robot mostly communicated through electronic sound effects), his physical performance as the robot was a crucial part of the show’s success.
