The procedure can be summarized as follows; the rescue robot will be brought in to the scene using external means like the Squad Mission Support System (SMSS) or air dropped into the disaster scenarios using a helicopter, similar to the marsupial concept used by REX/REV systems. Launched within range of the disaster scenario, the SAVER system will locate the injured, drive up to the person, estimate the posture and then align the person so that he/she can be easily transferred on to the stretcher. The head support system slides down the stretcher and stabilizes the head and neck of the person and then engages the shoulder support hooks. The injured person is then slowly pulled on to the declined stretcher. The various steps of the extraction procedure are detailed in figure.
