Bah, I didn't really mean "autonomous" but rather something that you program with a specific set of instructions and it executes them, and NOT something you control with a joystick from a remote location. That's not a robot, it's a remotely-operated device. A robot is something you give instructions to and it does it. A batch script on a computer is essentially a robot. An assembly machine in a car factory is a robot. There are tons of robots in the world, but something someone controls remotely isn't one of those.
