Now, the Robot is just a prop
Bob May died on January 18 at age 69. He was an American actor best remembered for playing The Robot on the television series Lost in Space, though the voice was done by voice actor and long time Irwin Allen announcer Dick Tufeld. From the imdb news links:
His co-star June Lockhart, who played Maureen Robinson, recalls, "He always said he got the job because he fit in the robot suit.
"It was one of those wonderful Hollywood stories. He just happened to be on the studio lot when someone saw him and sent him to see (series creator) Irwin Allen about the part.
"Allen said, 'If you can fit in the suit you've got the job.'"
May and his wife were left devastated in November after losing their family home in the wildfires that ravished parts of Southern California.
