PURPOSE: A surgery robot system and a control method thereof are provided to reduce feeling of fatigue of a surgical operator and to enhance efficiency of surgery.CONSTITUTION: An operation tracker(60) traces the movement of a hand of a surgical operator. The operation tracker comprises a camera(62) and an operation detection processor(64). The camera obtains an image of the movement of the hand of the surgical operator. The operation detection processor creates information of the movement of the hand of the surgical operator by analyzing the image obtained by the camera. Surgical instruments(38, 40) are driven by being synchronized to the movement of the hand of the surgical operator according to a driving signal. A signal processor(16) crates the driving signal of the surgical instruments.COPYRIGHT KIPO 2012본 발명에 따른 수술용 로봇 시스템은 시술자의 손의 움직임을 추적하는 동작 추적부, 동작 추적부에 의해 추적된 손의 움직임에 동기화되는 수술기구의 구동신호를 생성하는 신호처리부 및 구동신호에 따라 손의 움직임에 동기하여 구동되는 수술기구를 포함한다.
