The director is remaking the dystopian classic by Paul Verhoeven which follows a wounded policeman who is returned to the force as a cyborg.
Padilha told Dutch entertainment site film1: "I love the sharpness and political tone of RoboCop and I think that such a film is now urgently needed. But I will not repeat what Verhoeven has done so clearly and strongly.
"Instead I try to make a film that will address topics that Verhoeven untreated. If you are a man [who] changes into a robot, how do you do that?
"What is the difference between humans and robots developed? What is free will? What does it mean to lose your free will? Those are the issues."
The Elite Squad director will be helming from a script by Josh Zetumer, who worked on the unproduced Dune remake and the fourth Bourne film.
MGM originally pulled Black Swan director Darren Aronofsky into the project before the studio went into bankruptcy.
