Robotech is a science fiction franchise that was launched by an 85-episode adaptation of three different anime television series. Within the combined and edited story, Robotechnology refers to the scientific advances discovered in an alien starship that crashed on a South Pacific island. With this technology, Earth developed giant robotic machines or mecha (many of which were capable of transforming into vehicles) to fight three successive http://en.wiktionary.org/wiki/Extraterrestrial Extraterrestrial invasions.
Robotech was adapted into novel form by "Jack McKinney", a pseudonym for the team of James Luceno and the late Brian Daley, a pair of writers who had previously collaborated on the animated series Galaxy Rangers. Using fictitious epigraphs in the style of Dune, McKinney's novels fleshed out the chronology (including adapting the incomplete Sentinels source material) in greater detail.
A line of Robotech pen-and-paper role-playing games based on the Robotech and Sentinels series were published by Palladium Books from 1986 to 2001.
