The goal of the Center for Surgical Systems and Technology ( is to develop techniques and technology that will fundamentally change the operating room of the 21st century. Over the past eight years, this center has developed numerous systems for computer-integrated and computer assisted medical interventions. In this talk, I will argue that robotic surgical assistance provides a unique opportunity to study robotics, machine perception and human-machine interaction in circumscribed, but highly relevant applications. Using examples from our recent work on systems for the eye, throat, sinuses, and thorax, I will describe several technological and scientific problems we are tackling. These include the development of methods for creating augmented displays of the surgical field by fusing video with pre-operative imagery, control methods for human-machine cooperative control, and recent progress on recognizing surgical intent from hand motion data captured using the da Vinci surgical system.
