If you’ve watched popular sci-fi movies, you might be able to spot a common theme — computers and robots are bad. At some point, they’ll advance so far that they’ll rage against humanity.

If it’s so easy to imagine evil robots, why not imagine robots that fight on the side or righteousness? Recently, I’ve taken a big step in building my own robot army.
