Doyle is a fictional female Robot in the Andromeda series. The character was portrayed on screen by Brandy Ledford. Her allegiance / loyalty is to The Commonwealth. Doyle is a female robot who Seamus Harper built to replace Rommie when she (Rommie) was blown apart at the end of the previous series (series 4). Later in the fifth series, Harper builds a new Rommie. Even though Doyle is supposed to be a completely different and new robot to Rommie, Harper added memories of Rommie into Doyle's memory banks.
