Our vision about the future of surgical robotics includes the extension of the minimally invasive benefits of surgical robotics - increasing dexterity with reduced trauma and reduced healing time - to more surgical procedures that involve longer and more tortuous access pathways. In this article we present a series of analytic models that investigate the design tradeoffs involved in considering alternative transmission approaches for surgical robotics. We then evaluate their relative ability to efficiently deliver power and required performance. The results highlight the overall opportunity for high performance minimally invasive robotics with more stringent access geometries than current systems.
