This concept art for the SMRT-1 robot at EPCOT Center is dated May 3, 1982. SMRT-1 was featured at the Communicore exhibit and "spoke" with visitors via telephones while playing trivia games.
The Widen Your World website has a pretty thorough breakdown of the Communicore exhibit. Their photograph of SMRT-1 appears below. Communicore was closed in 1993 and converted into the Innoventions exhibit in 1994.
Be sure to check out one of the Paleo-Future blog's earliest posts, which happened to be about the The Computer Song. The Computer Song was from the Communicore attraction, Astuter Computer Revue, and certainly gives you a taste of the early-EPCOT atmosphere.
