Editing Robby the Robot (section)

==Later appearances==
The costly prop was used in numerous later productions for cinema and television, and the robot quickly became a science fiction [[pop icon|icon]] in the decades that followed. Robby was reused by MGM in ''[[The Invisible Boy]]'' (1957) and its television appearances include episodes of ''[[The Gale Storm Show]]'', ''[[The Thin Man (TV series)|The Thin Man]]'', ''[[Columbo]]'', ''[[The Addams Family]]'' and ''[[Lost in Space]]'' where he battles [[Robot (Lost in Space)|The Robot]]. While Robby's appearance was generally consistent, there were exceptions.

The original [[Rod Serling]] incarnation of ''[[The Twilight Zone (1959 TV series)|The Twilight Zone]]'', which was substantially filmed at MGM Studios, made extensive use of props and costumes originally created for ''Forbidden Planet'', including Robby, who appeared in three episodes over the series' original run: "[[One for the Angels]]" (s01e02, 1959), "[[Uncle Simon]]" (s05e08, 1963) and "[[The Brain Center at Whipple's]]" (s05e33, 1964). In "Uncle Simon" (1963), Robby's appearance was considerably altered, combining the familiar body with an alternative head piece. According to Robby's past owner, director William Malone, the head used in this episode was a prototype created during Robby's original construction at MGM. It featured a highly simplified and rather old-fashioned cylindrical "oil can" robot head with stylized "eyes" (that were illuminated and movable) and a circular "mouth"; this was enclosed under the distinctively-shaped conical plexiglass dome, but this head's front grille also did not have the blue neon tubes and lacked the rotating external "ear" pieces seen in ''Forbidden Planet''. It is not known whether this internal "oil-can" head was original, but its rather rudimentary design and appearance is clearly not of the same exacting MGM standards that are evident in all other ''Forbidden Planet'' props, and suggests it may have been custom-made for the filming of this ''Twilight Zone'' episode. However, this version of the prop survives and was also owned until recently by William Malone.

In other appearances, Robby usually retained the moving parts inside his transparent dome, although the details of his "brain" and chest panel were sometimes altered; in ''[[The Man from U.N.C.L.E.]]'' episode "The Bridge of Lions Affair", only Robby's head dome was used as part of a regeneration machine. Robby also appeared in the ''[[Mork & Mindy]]'' second-season episode "Dr. Morkenstein", this time representing a character called Chuck (voiced by actor [[Roddy McDowall]]) whom Mork befriends while working as a security guard in the science museum where Chuck is on display. Robby was given a major makeover for his appearance in the TV series ''[[Project U.F.O.]]'' (1978). The original head was removed and replaced with a newly constructed "cyclops" head that had new internal "brain" fittings, a much squatter (roughly hemispherical) perspex dome, and a large circular glowing green "eye" on the front, mounted in a protruding triangular panel. The front panel on Robby's torso was also modified with the addition of a new protruding panel, and additional appliances and cables were added to the front of both legs. This "cyclops" version of Robby was also used in the 1977 TV series ''[[Space Academy]]''<ref>[https://firebreathingdimetrodon.wordpress.com/2016/11/14/space-academy-1-12-my-favorite-marcia/ Space Academy 1.12 – My Favorite Marcia], November 14, 2016, Fire Breathing Dimetrodon Time</ref> and the 1988 [[B-movie]] ''[[The Phantom Empire (1988 film)|Phantom Empire]]''. All appearances of Robby after 1971 used a replica, as the original was retired and put on display in a southern California car museum (see below).

Robby made few appearances after the 1970s, but he does have a [[cameo appearance|cameo]] in the film ''[[Gremlins]]'' (1984); he can be seen standing in the background speaking some of his trademark lines. Aside from that, he also appeared in ''[[Looney Tunes: Back in Action]]'' (2003). He was also featured in a 2006 commercial for [[AT&T Inc.|AT&T]].

Robby the Robot was inducted into the [[Robot Hall of Fame]] in 2004.<ref name="Hall of Fame" />
