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 that's true, there can only be one defense — other robots. I can't fight as tirelessly as a robot. So if there are evil machines out there to get me, then I'll need ones to protect me. 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.
