A recent Star Trek marathon rebroadcast many of the early episodes. When Riker observes that Data is like Pinnochio he establishes the character's persona for the series.
As an ardent Asimov afficiando, (aliteraton anyone), I enjoyed the character Data, as much as his early guise as "Robbie the Robot"
"Warning Will robinson!!!"
And who can forget that sinister character from "Captain Video and his Video Rangers" You know, the evil Tobor, (which was robot spelled backwards)!
Actually, Robbie the Robot was from Forbidden Planet, not Lost in Space. They were NOT the same robot.
The robot on Lost in Space was just called Robot.
There was one episode they both appeared in.
