R2D2

When you think of robots and androids, it is hard not to imagine the vast universe of Star Wars. Not only is the series wildly popular world-wide, but it features so many different characters and species, including robotic heroes and villains. And one of the most famous of these robotic characters is the little astromech droid, R2D2. The little droid, from the very beginning, made a habit of going places that he shouldn't, and doing things that other droids would gawk at. From the beginning of the first movie, R2D2's first action is to disobey his companion C3PO's warnings, enter a secluded part of the ship they are traveling on, and then use an escape pod to evade the Empire forces. R2D2 plays against the idea of an ever-obeying robot, showing that even though he can only "speak" in beeps and whistles, the droid exhibits advanced thought and planning, and constantly aids his allies in their battles. R2 is a heroic robot, one that doesn't raise much thought in-universe; but fans find themselves asking "How can such a little droid get into so much trouble?" The droid shows quite a bit of free-will, a feature that is never spoken of in the series. C3PO, in comparison, is a docile android who only wishes to serve his master; the robot constantly complains about the mischief of R2, and the danger that his master gets into. C3PO is smart and sophisticated, but is obviously held back by his ever-obeying status. R2D2 doesn't speak but instead expresses his thought through his actions. If he is impatient, he will disobey commands and leave; if he is happy, he will wobble back and forth excitedly. R2D2 is closer to being human than his android counterpart, as he exhibits the emotions of a human far better, and constantly shows that he exhibits some amount of free will.
