 This 'Cyclops' version of Robby was also used in the 1977 TV series "Space Academy" and the 1988 video B-movie "Phantom Empire".All appearances of Robby after 1971 are a replica, as the original was retired and on display in a museum (see below).Robby has made few appearances after the 1970s, but he does make a cameo appearance in "Gremlins" (1984); he can be seen standing in the background and speaking some of his trademark lines.
