Abstract
The invention relates to a method for positioning an articulated arm of a medical robot assisted by a navigation system comprising an electromagnetic field generator and two sensors. The generated field forms a measurement zone in which the position of a sensor can be determined by the navigation system and communicated to the robot. A first sensor is positioned at an anatomical location of interest of a patient. A second sensor is positioned on the articulated arm. When the two sensors are located in the measurement zone, a so-called 'region of reduced influence' of the measurement zone is determined, in which the introduction of a metal object has virtually no influence on the determination of the position of the sensors by the navigation system. The articulated arm is then configured so that any metal part of the articulated arm located in the measurement zone is situated within the region of reduced influence.
