The only thing telling me this is supposed to be a robot is you calling it a robot.
If their intent with this design was to communicate "robot", they failed.
Seriously, why would you even put a miniskirt on a "female" battle robot?
Fabric does not go on that.
A and C solved that much better by making that armor plates as part of the legs.
And what is with that weird fixation on earmuffs anyway?
Edit:
So the male main character basically consists of plate armor and wears a helmet and the female one is generic animu girl in a miniskirt.
Ok...
