Terminator but others are cool too.
C3PO, of course.
I always liked that robot from the 50's.
I only know about 3 of these robots but checked out the others too. Terminator seem to be the coolest one.
he was almost human
It certainly wouldn't be C3PO -- I know the guy they probably modelled him on and he's no fun at all.
I think I'll settle on R. Daneel Olivaw -- a most remarkable robot from Isaac Asimov.
It would have to be Robby. There were others before him like Klatu but Robby was cool.
