My dinner discussion tonight:
What is the minimum and necessary things for something to be a robot?
We got a loop, and a conditional option, physical actuation, an input of some kind:
Robot: printer, jacquard loom, radio.
Not a robot: Key and lock, light switch, fake perpetual motion machine, computer with only an LCD display as the output.
Is the electron beam in a CRT physical actuation, LCDs?
If an analog computer drives a car, is that a robot?
