WOPR is missing because it'd be too big. DARYL isn't shown because he looks human. No artificial lifeform that looks human at first glance (DARYL, the new Cylons, Major Kusanagi) seems to be shown in the picture.
* The red one behind C-3PO is from the
Go-Bots cartoon series. Can't recall his name, but I know he's one of the good guys, known as Guardians. In front of C-3PO is a Sentinel from the
Matrix movies.
* Behind the Dalek is Bender, from
Futurama. To the left of the Dalek is Andrew Martin, main character of the movie
Bicentennial Man, played expertly by Robin Williams. To the right of the Dalek is Dorothy's companion, the Tin Woodsman.
* To the right of Tin Woodsman, behind the one with the red cap, is Nomad, who appeared in
Star Trek: TOS.
* To the right of Rosie from the Jeffersons, behind the robot from the Heavy Metal movie, is a turquoise-colored robot I can't identify. The one to the right of
that robot, with the oval-shaped head and dark blue eyes, is an unnamed robot featured in
Rocky IV. It was a birthday present for Paulie.
* The red robot all the way to the back is Maximillian, a bad guy from the movie
The Black Hole. Also from
The Black Hole is good guy V.I.N.Cent, who is near the front, behind and to the right of the violin-playing egg. He has a cylindrical head with square eyes.
* In front of Maximillian is the T-1000, from
Terminator 2 (there were times when it clearly didn't look human, as shown there). Two robots to the right of Maximillian is (IIRC) Klaatu, from the original version of
The Day The Earth Stood Still (trivia: the phrase featured in
Army of Darkness, "klaatu barata nikto", was Klaatu's shutdown code).
* The clockwork owl, to the left of the transparent dome on the right side of the picture, appeared in the original
Clash of the Titans movie.
* In the back, third from the right, is ED-209, from the
Robocop movies. In front of ED-209 is Dot Matrix, the golden android from
Spaceballs. The blue spider-like thing to the left of Dot Matrix is a Tachikoma, from the anime series
Ghost in the Shell: Stand Alone Complex. The rust-colored robot to the left of the Tachikoma is the ABC war-bot from the
Judge Dredd movie.
* Near the center of the picture is a cross-eyed robot with a transparent dome atop its head. Behind that robot is Atlas, found in the co-op mode of
Portal 2.
* In the very front, all the way to the right, is the "mouse droid" found in the
Star Wars movies, usually on the Death Star (a funny moment happens when one is rolling along and meets Chewbacca, Chewie roars at it, and it flees in total panic mode).
