As a child of 7 in 1967, THIS was my favorite show: It featured a family named Robinson whose father was an astronaunt going into space on a space ship named the Jupitor 2. Along for the ride was the Robot, whose name was Robot; a handsome copilot who was in love with the eldest daughter, and of course the antagonist himself, Dr. Smith. The many adventures of the Robinson family during their journey thru space and time kept me and my sisters and kid brother on the edge of our seats!

Saboteur Dr. Zachary reprograms the Robot to "Destroy" the Jupiter 2 and Crew, except Spy gets stuck in ship, poetic justice! Kudos, Robot B9!
