Claim 8:
9. A method of guiding a drill during robot-assisted surgery on an anatomical feature of a patient, the method comprising the steps of:
determining, by computer processing, a drill target and an associated drill trajectory and effectuating movement of an end-effector to a position corresponding to the determined target and the determined drill trajectory;
coupling a drill guide to the end effector, the drill guide having a guide sleeve adapted to receive a drill bit attached to a drill, and a depth stop sleeve slidably received in the guide sleeve and longitudinally lockable to the guide sleeve, the depth stop sleeve having a through hole to allow the drill bit to be freely slidable therein,
setting a depth stop of the depth stop sleeve by longitudinally sliding the depth stop sleeve relative to the guide sleeve;
locking the set depth stop;
inserting the drill bit through the locked depth stop sleeve and the guide sleeve of the drill guide such that a distal tip of the drill bit extends from a distal end of the drill guide;
drilling the anatomical feature with the inserted drill bit until the locked depth stop of the depth stop sleeve stops the drill from advancing further.
