I once had a robotics professor who argued any definition of 'robot' broad enough to include roombas and self-driving cars and industrial robot arms (even if made narrow enough to exclude remote-control toy cars, cars with cruise control, CNC mills and washing machines) would inevitably define cruise missiles as robots. Meaning the world had 'killer robots' before we had digital computers.
Instead, he argued the definition of a robot is "I know it when I see it"
