Greg Miller stated in an interview on Facebook that he used a Microsoft Word 98 text-to-speech software on his old Macintosh computer for Robot's voice during production for season one, but after the first season was completed, the executives of Cartoon Network disliked how it sounded. Bobby Block was chosen to take the role of Robot in season two. Robot Jones's text-to-speech voice was also recorded for production of the second season, but because the voice change happened during the production of those episodes, this voice was never dubbed into the final prints. In that interview, he also said that he would want to do a revival of Robot Jones, but it would be up to Cartoon Network.
