Abstract: An articulated robotic platform is provided as an end-actuator intended to be fitted to an articulated robotic arm. One use of the articulated robotic platform is to more accurately guide surgical tools during a surgical intervention making it possible to achieve positional accuracy on the level of millimeters or fractions of a millimeter. The articulated robotic platform includes support members attached to the patient or anchoring the articulated robotic platform onto a clamp. The support members of the articulated robotic platform are capable of changing in length, and this change can be monitored by an extension measurement sensor fitted to one or more of the support members. The controller, when provided with feedback information of the extension measurement and direction of several of the legs, can calculate accurately the position of the articulated robotic platform relative to an intervention area of a patient.
