A movie i watched as a kid with a deadly robot

I swear every once in a while i try to remember the name of this movie but i fail every single time, as the title say the film is very old and probably not the terminator saga, the protagonist was a woman and probably in some hot place like a desert, and there was this deadly robot who tried to kill her…at the end i remember she succedeed to kill the robot maybe and i say maybe detonating some explosives…i watched it probably 20 years ago that’s all i can say for sure
