B9... there's a pun in there, when one thinks of how the "Lost In Space" robot's personality was initially introduced in episode #1; he nearly destroyed the Jupiter 2.

This is a full scale replica of "The Robot" from the show, on display at the Kennedy Space Center Visitor's Center. While it does not respond with the classic, "Danger Will Robinson. Danger!," it's still lit up as you can see.

I showed this to my youngest brother, who's always liked this gizmo.
