14. A method for drilling a hole in a cranium of a patient in connection with cranial surgery, the method comprising:
providing a surgical robot system including:
a surgical robot;
a robot arm connected to the surgical robot;
an end-effector connected to the robot arm;
a perforator connectable to the end-effector and configured to be advanced or withdrawn relative to the cranium, the perforator having an elongated bit terminating in a sharp, perforator tip, the bit having a bit diameter, the perforator having a clutch operable to rotate the bit in response to detection by the surgical robot of resistance during advancement of the bit and further operable to stop bit rotation in response to detection by the surgical robot of penetration past an internal wall of the cranium,
maintaining the perforator bit along a trajectory line;
moving the bit in a conical oscillation relative to the trajectory line during advancement of the perforator tip into the cranium.
