Calling things "robots" is more about the amount of movement. Spinning in place like a washing machine sprayer isn't enough to qualify.
A paint conveyer belt is not a robot. A sprinkler system is not a robot. A CnC machine might be a robot. A conveyer belt that sorts items might be a robot. A roomba is a robot. And all of these function just fine.
I think of robots as general purpose, machines are specific purpose. When it works, we make it single purpose because that’s far far cheaper than general purpose.

No, it would have been called what it is both then and now; an asynchronous message emitted by a device having sensors capable of detecting when to do so.
