Abstract: The introduction of robotics in medical field was considerable in the last decade, thanks to the progress in mechatronics and in minimally invasive surgery (MIS). The MIS reduces the surgical incisions limiting the patientís trauma and the post-operative stay. Nevertheless it requires more dexterity than a classical operation and, consequently, new devices have to be developed to meet this requirement. This paper presents the kinematic design of a new robot for neurosurgical operations, named NEUROBUD. This robot is a six joints serial manipulator whose redundancy with respect to the surgical task allows the surgeon to choose a suitable robot configuration, in order to minimally limit his movements during the surgical operations.
