Re: Nice review...
Generally, just a rough idea:
Robot: Mechanical device, including bipedal humanoid types. Aka Droids, drones. Dewy and Huey from Silent Running, R2D2
Android: A robot designed to resemble a human, some indistinguishably. StarTrek's Data, R. Daneel Olivaw, Yule Brynner, The Terminator, Cylons from BSG, Replicants, Ash, Bishop, Call and David, Artificial People
Cyborg: A man/machine mixture. Cybermen, The Borg. Robocop.
These aren't hard-and-fast categories, though.
