Hollywood and the movie industry have turned out some very memorable robots. You can think of R2D2 and C3PO, the Laurel and Hardy of science fiction. What do you like most about these two? Could it be their personalities? Think about this a bit. Even though R2D2 is mostly a wastebasket shape with a dome head and no face, he has a definite personality. You describe him as feisty, or stubborn. The website Robots and Androids (http://www.robots-and-androids.com/R2D2.html) described him this way:
“The droid is shown as being highly courageous, unwavering in loyalty, and a little bit stubborn. He never backs down from a mission, even when the odds appear to be stacked against him. His personality is often contrasted against that of [C3PO], who is fussy and timid.”
This is pretty impressive for a robot who never says a word and communicates...
