Asimov's last words about his robots may have been his introduction to
Robot Visions.
In it he listed the 16 robot stories that he considered particularly significant. They were "Robbie," "Reason," "Liar!," "Runaround,'' "Evidence," "Little Lost Robot," "The Evitable Conflict" all from
I, Robot
"Franchise," "The Last Question," "The Feeling of Power," "Feminine Intuition," "The Bicentennial Man,"
The Caves of Steel, The Naked Sun, The Robots of Dawn,
and
Robots and Empire.
He also mentioned some of the other stories he was fond of but that broke no new ground, among them "Galley Slave," "Lenny," "Someday," "Christmas Without Rodney," "Think!," "Mirror Image," "Too Bad!," and "Segregationist."
