Med-droids are androids programmed to give basic medical examinations, such as blood tests and heart rate monitoring. They are also used to safely transport victims of letumosis to quarantines without risk of contaminating other humans. They are also equipped with ID chip scanners. In Cinder, several med-droids were programmed by the Lunars to steal identity chips from those who died of letumosis to use for their special operatives.
Med-droids are the primary caretakers of those sick with letumosis, due to their ability to take care of patients without getting infected themselves.
Their appearance is that of a hovering white android with yellow sensors and red crosses painted on their heads. They are insinuated to be shorter than the average human.
