Start as you mean to go on.
From the feedback scream at the start, through the pounding bass line and the well constructed melody, there is a certain degree of malice to the piece, as if someone was stalking Johnny 5 from Short Circuit in some sort of macabre visage of a horror film gone cheesy.
I think that making it mechanical means that the next place to take this sound would be to explore some of the industrial genre, giving light to certain sounds like pneumatic hammer presses falling in an apocalyptic thumping of a beat - slower and more purposeful, to compliment this style. Of course, there's much more there to choose from, so have a play and see what you could do.
I have to admit that by the time the tune had finished, I felt quite sorry for the screaming robot / computer / automaton, who is inevitably going to die. Certainly a good chase scene.
