True on both accounts. Robbie the Robot was from the classic 1950s SciFi film Forbidden Planet. That movie was the inspiration for a lot of 1960s and beyond SciFi TV shows. Forbidden Planet also introduced the concept of a personal communicator, although unlike the wireless version in Star Trek it was wired to their belt area of the uniforms. Great movie BTW, my favorite SciFi movie from the 1950s. I don't think the dorky robot in Lost in Space even had a name.

I'm pretty sure the Lost in Space robots "prime directive" was to incinerate that creepy, old, pedophile looking jerk who was always running around with the kid if he got to chummy. What stupid parents would let their kid hang out with that creep? LOL! As a child in the 1960s that character creeped me out considerably. I laughed when I saw their fake space monsters, but shuttered when I saw their resident creep!
