Everything I've ever seen says that pipettor is in fact the pipette with additional components, not the scientist or the robot. https://www.sigmaaldrich.com/US/en/products/labware/liquid-h...

It's just terminology, "regular" pipets dispense mainly in milliliters, micropipets dispense in microliters.

The pipet is considered the tube, the pipettor is the mechanical attachment, I would say that is whether the attachment is with lips & tongue or not.
