Minimally invasive robotic surgery systems strive to combine the advantages of conventional minimally invasive surgery with those of open surgery. However, surgeons loose their sense of touch. The first step towards restoring this important haptic mode of perception is measuring tissue interaction forces at the operation site. The novel tool presented in this thesis allows for full intra corporal force measurement at the tool tip. The thesis shows the development of the currently smallest 6 degrees of freedom force-torque sensor with several Newtons measurement range. The sensor is combined with a 2 degrees of freedom articulated wrist for enhanced dexterity, and a generic tip for tissue manipulation. High quality force measurement is achieved by mechanically decoupling the tool actuation forces from the tissue interaction force measurement.
