"Robot Laboratory ~ The Past That Doesn't Disappear" (ロボット研究室 ～消えない過去), sometimes translated as "Robot Laboratory ~ Unerasable Past", is a music track from Phoenix Wright: Ace Attorney: Dual Destinies associated with Aura Blackquill and the UR-1 Incident. The track plays in The Cosmic Turnabout when Aura tells Phoenix Wright of her distrust in the legal system that resulted from the false conviction of her brother Simon Blackquill, and during Wright's encounter with Aura and Apollo Justice in the robotics lab in Turnabout for Tomorrow, when Aura and Clonco talk about Metis Cykes and the research she worked on with Aura.
