Sounds like Star Wars, but the black-clad villain who kills one of the good guys in the end is actually a cyborg instead of a robot. ;)

Starchaser: The Legend of Orin is very similar to Star Wars, and its version of Vader actually is a robot. It's animated, though, so that might not be it.

I saw this movie when I was a kid, but I can't remember what it was called. It starts in a desert, and the heroes eventually end up going to a space station or something. The villain was a black robot and I remember he kills one of the heroes at the end.
